NAME
XmContainer - The Container widget class
SYNOPSIS
#include <Xm/Container.h>
VERSION
This page documents Motif 2.1.
DESCRIPTION
Container manages child widgets that have the ContainerItem
trait. These child widgets can be viewed in several
different layout formats, selected using different selection
types and techniques, and directly manipulated by the user.
Three different formats or views are supported by the
Container. They are specified via the XmNentryViewType
resource:
⊕ XmLARGEICON
⊕ XmSMALLICON
⊕ XmANYICON
Three different layout types are supported by the Container.
They are specified by the XmNlayoutType resource:
⊕ XmSPATIAL
⊕ XmOUTLINE
⊕ XmDETAIL
In the XmSPATIAL layout type, several other resources
(XmNspatialStyle, XmNspatialIncludeModel,
XmNspatialSnapModel) control the positioning of the items
within the Container; an application programmer can specify
these resources so that the Container strictly enforces the
position of each item or so that the Container positions
items according to constraint resources specified for each
item. The user, however, can alter the position of an item
in the XmSPATIALlayout type within the Container by direct
manipulation; for example, by pressing BTransfer over the
item and then dragging and releasing BTransferover some
location within the Container.
In the XmOUTLINE layout type, the Container controls the
positioning of the items. Items within the Container can
have parent-child relationships between them. Each item's
XmNentryParent resource can specify another item in the same
Container as its parent; items with a non-NULL value for
Page 1 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
XmNentryParent can only be displayed in the XmOUTLINE layout
type. In the XmOUTLINE layout type, items are positioned in
a tree configuration with connecting lines drawn to
illustrate the relationships. Items are positioned top to
bottom in the order specified by XmNpositionIndex within
their parent. Container positions a PushButton next to each
item that has a parent relationship to other items. The
PushButton contains a pixmap to illustrate whether the child
items are shown or not; the user can activate the PushButton
to toggle between showing or hiding the child items. Direct
manipulation to alter the position of the item is not
supported in the XmOUTLINE layout type. Note that the
XmNtraversalOn resource of the PushButtons created by
Container are set to False.
The XmDETAIL layout type is the same as XmOUTLINE, except
that each item can also display additional information as
rows in columns with column headers specified in the
XmNdetailColumnHeadingresources. In each item row, the
item's detail information (see the reference page on
XmIconGadget for a description of the XmNentryDetail
resource) is displayed. Items are positioned top to bottom
in the order specified by XmNpositionIndex within the
parent.
Selection
When a child widget of the container is selected, the
container specifies that the item should display the
appropriate visual information to the user via the
ContainerItem trait. The application program is notified of
selection changes through XmNselectionCallback.
The container uses four selection policies:
⊕ Single
⊕ Browse
⊕ Multiple
⊕ Extended
In Single Select and Browse Select modes, only one item can
be selected at a time. Pressing BSelecton an item selects it
and deselects any other selected item. Pressing BSelect
over an empty space in the Container deselects all items. In
Browse Select, dragging BSelect moves the selection as the
pointer is moved.
In Multiple Select and Extended Select modes, any number of
items can be selected at the same time. In Multiple Select,
pressing and dragging BSelect or BExtend to specify an item,
Page 2 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
range of items, or group of discontiguous items causes the
selection states of those items to be toggled. In Extended
Select, pressing and dragging BSelect to indicate an item,
range of items, or group of discontiguous items selects
those items and deselects all others. Pressing and dragging
BExtend in Extended Select to indicate an item, range of
items, or discontiguous group of items causes the selection
states of those items to be toggled.
Several techniques are available to indicate an item, range
of items, or group of discontiguous items in the Multiple
Select and Extended Select modes.
In the XmSPATIAL and XmOUTLINE layout types, the
XmNselectionTechnique resource specifies the techniques to
be used to indicate items. The default specification of
XmTOUCHOVERallows both the Random-Swipe and Marquee
techniques to be used when XmNlayoutStyle is XmSPATIAL. The
default specification of XmTOUCHOVER allows the Range-
Swipe, Range-Click, and Marquee techniques to be used when
XmNlayoutStyle is XmOUTLINE.
Discontiguous groups of items can be selected using the
Random-Swipe technique. In the Random-Swipe technique,
pressing BSelect (or BExtend) over an item and dragging
BSelect over other items selects all of those items. Only
those items that pointer passed over are selected.
In the Range-Swipe technique, the user presses BSelect (or
BExtend) over the first item and releases BSelect over the
last item; all items within the range between the first and
last item are selected whether the pointer actually passed
over them or not. In the Range-Click technique, the user
presses and releases BSelect (or BExtend) over the first
item and then presses and releases BExtend over the last
item.
In the Marquee technique, pressing BSelect (or BExtend) over
a blank space within the Container indicates the starting
point of a Marquee rectangle. Dragging BSelect draws a
Marquee rectangle (rubberband line) between the starting
point and current pointer. All items completely within the
Marquee rectangle are selected.
Specifying XmTOUCHONLY for XmNselectionTechnique enforces
the Random-Swipe technique even when BSelect (or BExtend) is
pressed over a blank space. Similarly, specifying XmMARQUEE
enforces the Marquee technique even when BSelect (or
BExtend) is pressed over an item; since the item over which
the press occurs is only partially included in the Marquee
rectangle, it is not selected. XmMARQUEEEXTENDSTART and
XmMARQUEEEXTENDBOTH enforce the Marquee technique and also
Page 3 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
cause the rectangle to extend automatically around the first
item indicated and, for XmMARQUEEEXTENDBOTH, the last
item.
In the XmDETAIL layout type, the Range-Swipe and Range-Click
techniques are available to indicate a range of items for
selection.
Container uses the XmQTcontainerItem, XmQTscrollFrame, and
XmQTspecifyRenderTabletraits and holds the XmQTcontainer and
XmQTtransfer traits.
Data Transfer Behavior
Container supports dragging of selected items from the
widget. Depending on the value of XmNprimaryOwnership,
Container can also support primary selection.
As a source of data, Container supports the following
targets and associated conversions of data to these targets:
locale If the locale target matches the widget's locale,
the widget transfers the selected items in the
encoding of the locale. The value for each item
transferred, except the last, includes a trailing
separator. Each item value is the XmNlabelString
of the item.
COMPOUND_TEXT
The widget transfers the selected items as type
COMPOUND_TEXT. The value for each item
transferred, except the last, includes a trailing
separator. Each item value is the XmNlabelString
of the item.
DELETE The widget deletes the selected items.
PIXMAP The widget transfers a list of the pixmap IDs of
the selected items as type DRAWABLE.
STRING The widget transfers the selected items as type
STRING. The value for each item transferred,
except the last, includes a trailing separator.
Each item value is the XmNlabelString of the item.
TEXT If the selected items are fully convertible to the
encoding of the locale, the widget transfers the
selected items in the encoding of the locale.
Otherwise, the widget transfers the selected items
as type COMPOUND_TEXT. The value for each item
transferred, except the last, includes a trailing
separator. Each item value is the XmNlabelString
of the item.

XmContainer(3X) UNIX System V XmContainer(3X)
MOTIFCLIPBOARDTARGETS
The widget transfers, as type ATOM, a list of the
targets it supports for immediate transfer for the
CLIPBOARD selection. These include
MOTIFCOMPOUNDSTRING and PIXMAP. If the
selected items are fully convertible to STRING,
these also include STRING; otherwise, they also
include COMPOUND_TEXT.
MOTIFCOMPOUNDSTRING
The widget transfers the selected items as a
compound string in Byte Stream format. The value
for each item transferred, except the last,
includes a trailing separator. Each item value is
the XmNlabelString of the item.
MOTIFDEFERREDCLIPBOARDTARGETS
The widget transfers, as type ATOM, a list of the
targets it supports for delayed transfer for the
CLIPBOARD selection. This widget currently
supplies no targets for
MOTIFDEFERREDCLIPBOARDTARGETS.
MOTIFDRAGOFFSET
The widget transfers a list of two 16-bit numbers,
of type INTEGER, representing an x and y offset
for an item being dragged. This offset is
calculated so that, if the offset were added to
the x and y coordinates at the drop site, and the
dragged pixmap placed at that position, it would
correspond to the position the user would expect
the pixmap to placed at, based on the drag icon
used at the drop site.
MOTIFEXPORTTARGETS
The widget transfers, as type ATOM, a list of the
targets to be used as the value of the
DragContext's XmNexportTargets in a drag-and-drop
transfer. These include MOTIFCOMPOUNDSTRING,
PIXMAP, COMPOUND_TEXT, the encoding of the locale,
STRING, TEXT, BACKGROUND, and FOREGROUND.
As a source of data, Container also supports the following
standard Motif targets:
BACKGROUND
The widget transfers XmNbackground as type PIXEL.
CLASS The widget finds the first shell in the widget
hierarchy that has a WMCLASS property and
transfers the contents as text in the current
locale.
Page 5 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
CLIENT_WINDOW
The widget finds the first shell in the widget
hierarchy and transfers its window as type WINDOW.
COLORMAP The widget transfers XmNcolormap as type COLORMAP.
FOREGROUND
The widget transfers XmNforeground as type PIXEL.
NAME The widget finds the first shell in the widget
hierarchy that has a WMNAME property and
transfers the contents as text in the current
locale.
TARGETS The widget transfers, as type ATOM, a list of the
targets it supports. These include the standard
targets in this list. These also include
MOTIFCOMPOUNDSTRING, PIXMAP, COMPOUND_TEXT, the
encoding of the locale, STRING, and TEXT.
TIMESTAMP The widget transfers the timestamp used to acquire
the selection as type INTEGER.
MOTIFRENDERTABLE
The widget transfers XmNrenderTable if it exists,
or else the default text render table, as type
STRING.
MOTIFENCODINGREGISTRY
The widget transfers its encoding registry as type
STRING. The value is a list of NULL separated
items in the form of tag encoding pairs. This
target symbolizes the transfer target for the
Motif Segment Encoding Registry. Widgets and
applications can use this Registry to register
text encoding formats for specified render table
tags. Applications access this Registry by
calling XmRegisterSegmentEncoding and
XmMapSegmentEncoding.
As a destination for data, Container supports only the
dropping of items being dragged from the same widget.
Subclasses and the XmNdestinationCallback procedures are
responsible for any other data transfers to the widget.
Classes
Container inherits behavior, resources, and traits from the
Core, Composite, Constraint, and XmManager classes.
The class pointer is xmContainerWidgetClass.
The class name is XmContainer.

New Resources
The following table defines a set of widget resources used
by the programmer to specify data. The programmer can also
set the resource values for the inherited classes to set
attributes for this widget. To reference a resource by name
or by class in a .Xdefaults file, remove the XmN or XmC
prefix and use the remaining letters. To specify one of the
defined values for a resource in a .Xdefaultsfile, remove
the Xm prefix and use the remaining letters (in either
lowercase or uppercase, but include any underscores between
words). The codes in the access column indicate whether the
given resource can be set at creation time (C), set by using
XtSetValues(S), retrieved by using XtGetValues (G), or is
not applicable (N/A).

XmNautomaticSelection
Indicates whether the Container invokes selection
callbacks when each item is selected (or toggled)
or whether selection callbacks are not invoked
until the user has completed selection actions
(for example, the user has released the mouse
button). It can have one of the following values:
XmAUTOSELECT
Makes selection callbacks automatically
when each item is selected or toggled.
This may also be the value TRUE.
XmNOAUTOSELECT
Delays selection callbacks until the
user has finished selection actions.
This may also be the value FALSE.
XmNcollapsedStatePixmap
Specifies the pixmap to display on a PushButton
next to a Container item with child items, when
XmNoutlineButtonPolicy is
XmOUTLINEBUTTONPRESENT. XmNcollapsedStatePixmap
indicates that the child items are not displayed.
If set to XmUNSPECIFIEDPIXMAP, a default pixmap
showing an arrow pointing up is used.
XmNconvertCallback
Specifies a list of callbacks called when the
Container is asked to convert a selection. The
type of the structure whose address is passed to
these callbacks is XmConvertCallbackStruct. The
reason is XmCROK.
XmNdefaultActionCallback
Specifies a list of callbacks to call when the
user double-clicks an item or presses <Enter> or
<Return> over an item. The callback structure is
XmContainerSelectCallbackStruct. The reason is
XmCRDEFAULTACTION.
XmNdestinationCallback
Specifies a list of callbacks called when the
Container is the destination of a transfer
operation. The type of the structure whose
address is passed to these callbacks is
XmDestinationCallbackStruct. The reason is
Page 8 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
XmCROK.
XmNdetailColumnHeading
Specifies a table of XmStrings to display as the
headings to columns. If NULL, or if
XmNlayoutTypeis not XmDETAIL, no heading is
displayed.
XmNdetailColumnHeadingCount
Specifies a count of XmStrings in the table
specified for XmNdetailColumnHeading.
XmNdetailOrder
Specifies an array of Cardinals that indicate
which column detail information, and in which
order, each Container child will display its
detail information. This resource is ignored if
XmNlayoutType is not XmDETAIL. If NULL, the the
default behavior is determined by
XmNdetailOrderCount.
XmNdetailOrderCount
Specifies a count of Cardinals in the array
specified for XmNdetailOrder. If XmNdetailOrder
is NULL and XmNdetailOrderCount is not 0, then
each Container child displays its detail
information in order from column 1 to the
XmNdetailOrderCount column number. If
XmNdetailOrderCountis 0, then a default is
calculated from the detail order count information
of each item accessed via the ContainerItem trait.
XmNdetailTabList
Indicates an XmTabList specifying the start of
each column in the XmDETAIL layout. If this
resource is set to NULL, then Container calculates
an XmTabList. This resource is ignored if
XmNlayoutType is not XmDETAIL.
XmNentryViewType
Specifies the view type for all Container
children. The view type is specified for each item
via the ContainerItem trait. It can have one of
the following values:
XmANYICON
No specification is made for Container
children. Children use their own default
specifications.
XmLARGEICON
The view type for all children is
Page 9 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
XmLARGEICON.
XmSMALLICON
The view type for all children is
XmSMALLICON.
XmNexpandedStatePixmap
Specifies the pixmap to display on a PushButton
next to a Container item with child items, when
XmNoutlineButtonPolicy is
XmOUTLINEBUTTONPRESENT. XmNexpandedStatePixmap
indicates that the child items are displayed. If
set to XmUNSPECIFIEDPIXMAP, a default pixmap
showing an arrow pointing down is used.
XmNfontList
Specifies the fontlist associated with
XmContainer. The fontlist is an obsolete construct
and has been superseded by the render table. It
is included for compatibility with earlier
versions of Motif, and for applications that do
not easily support render tables. The default
fontlist is derived from the default render table;
and if both a fontlist and a render table are
specified, the render table takes precedence.
XmNlargeCellHeight
Specifies the height of a cell for XmGRID or
XmCELLS spatial style when XmNentryViewType is
XmLARGEICON or XmANYICON.
XmNlargeCellWidth
Specifies the width of a cell for XmGRID or
XmCELLS spatial style when XmNentryViewType is
XmLARGEICON or XmANYICON.
XmNlayoutType
Specifies the policy for laying out child widgets
within the Container. It can have one of the
following values:
XmDETAIL Displays items in the same manner as
when the resource is XmOUTLINE, except
that each item displays detail
information next to it.
XmOUTLINE Displays items in a tree configuration,
in XmNpositionIndex within
XmNentryParent order, with connecting
lines drawn to show their parent-child
relationships.
Page 10 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
XmSPATIAL Displays items according to
XmNspatialStyle. Items with
XmNentryParent values are not displayed.

XmOUTLINEBUTTONABSENT
Do not display the outline buttons.
XmOUTLINEBUTTONPRESENT
Display the outline buttons.
XmNoutlineChangedCallback
Specifies a list of callbacks to call when an
item's XmNoutlineStateis changed. The callback
structure is XmContainerOutlineCallbackStruct.
The reason is XmCRCOLLAPSED or XmCREXPANDED,
depending on the new value of XmNoutlineState.
XmNoutlineColumnWidth
Specifies the width of the first column displayed
when XmNlayoutTypeis XmDETAIL. Specifies the
preferred width of the Container (without the
margins) when XmNlayoutType is XmOUTLINE. If not
specified, Container will determine a default
value equal to the widest space necessary to
display an item's pixmap and
XmNoutlineIndentation.
XmNoutlineIndentation
Specifies the distance to indent for the display
of child items when XmNlayoutType is XmOUTLINE or
XmDETAIL.
XmNoutlineLineStyle
Specifies whether to draw lines between items with
parent-child relationships when XmNlayoutTypeis
XmOUTLINE or XmDETAIL. It can have one of the
following values:
XmNOLINE Draws no line.
Page 11 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
XmSINGLE Draws a line one pixel wide.
XmNprimaryOwnership
Specifies whether Container takes ownership of the
primary selection when a selection is made inside
it. This resource can take the following values:
XmOWNNEVER
Never takes ownership.
XmOWNALWAYS
Always takes ownership.
XmOWNMULTIPLE
Only takes ownership if more than one
element has been selected.
XmOWNPOSSIBLEMULTIPLE
Only takes ownership if more than one
element can be selected at a time.
XmNrenderTable
Specifies the XmRenderTable that is inherited by
all children of the Container. The default is
implementation dependent. If both a render table
and a fontlist are specified, the render table
will take precedence.
XmNselectColor
Specifies a Pixel that can be accessed by children
of the Container and used to indicate that the
child is in a selected state. In addition to a
Pixel value, the following symbolic values can be
specified:
XmDEFAULTSELECTCOLOR
Specifies a color between the background
and the bottom shadow color.
XmREVERSEDGROUNDCOLORS
Forces the select color to the
foreground color and causes the default
color of any text rendered over the
select color to be the background color.
HIGHLIGHT_COLOR
Forces the fill color to use the
highlight color.
XmNselectedObjectCount
Specifies the number of widgets in the selected
items list. The value must be the number of items
Page 12 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
in XmNselectedObjects.
XmNselectedObjects
An array of widgets that represents the Container
items that are currently selected, either by the
user or by the application.
If the application sets XmNselectedObjects to an
array of widgets, those array elements that are
valid Container items are selected.
XmNselectionCallback
Specifies a list of callbacks to call when an item
is selected. The callback structure is
XmContainerSelectCallbackStruct. The reason is
XmCRSINGLESELECT, XmCRBROWSESELECT,
XmCRMULTIPLESELECT, or XmCREXTENDEDMULTIPLE,
depending on XmNselectionPolicy.
XmNselectionPolicy
Defines the interpretation of the selection
action. This can be one of the following values:
XmSINGLESELECT
Allows only single selections.
XmBROWSESELECT
Allows "drag and browse" selections.
XmMULTIPLESELECT
Allows multiple selections.
XmEXTENDEDSELECT
Allows extended selections.
XmNselectionTechnique
Specifies the selection technique to use when the
Container displays items in a 2-dimensional layout
(XmNentryViewType is XmLARGEICON or
XmSMALLICON). In the XmDETAIL layout, the
XmNselectionTechniqueresource is treated as
XmTOUCHONLY. In either case, it can have one of
the following values:
XmMARQUEE Uses the Marquee technique only.
XmMARQUEEEXTENDSTART
Uses the Marquee technique only and
extends the Marquee rectangle around any
item under the Marquee start point.
XmMARQUEEEXTENDBOTH
Page 13 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
Uses the Marquee technique only and
extends the Marquee rectangle around any
items under the Marquee start and end
points.
XmTOUCHONLY
Uses the Random-Swipe technique only if
XmNlayoutType is XmSPATIAL. Otherwise,
uses the Range-Swipe and Range-Click
techniques.
XmTOUCHOVER
If the selection action begins over an
item and XmNlayoutType is XmSPATIAL,
uses the Random-Swipe technique. If the
selection action begins over an item and
XmNlayoutType is XmOUTLINE or XmDETAIL,
uses the Range-Swipe and Range-Click
techniques. Uses the Marquee technique
if the select action begins over an
unoccupied area in the Container.
XmNsmallCellHeight
Specifies the height of a cell for XmGRID or
XmCELLS spatial style when XmNentryViewType is
XmSMALLICON.
XmNsmallCellWidth
Specifies the width of a cell for XmGRID or
XmCELLS spatial style when XmNentryViewType is
XmSMALLICON.
XmNspatialIncludeModel
Specifies the layout of an item when the item is
managed in the Container when XmNlayoutType is
XmSPATIAL and XmNspatialStyle is XmGRID or
XmCELLS. It can have one of the following values:
XmAPPEND Places the item after the last occupied
cell according to XmNlayoutDirection.
XmCLOSEST Places the item in the free cell closest
to the position specified by XmNx and
XmNy.
XmFIRSTFIT
Places the item in the first free cell
according to XmNlayoutDirection.
XmNspatialResizeModel
Specifies how Container will attempt to grow its
dimensions when XmNlayoutType is XmSPATIAL and
Page 14 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
XmNspatialStyle is XmGRID or XmCELLSand there are
not enough cells to contain a new Container item.
It can have one of the following values:
XmGROWBALANCED
Container will request both width and
height growth from its parent.
XmGROWMAJOR
Container will request growth in its
major dimension from its parent.
Container's major dimension is width
when the precedence of
XmNlayoutDirection is horizontal, and
height when vertical.
XmGROWMINOR
Container will request growth in its
minor dimension from its parent.
Container's minor dimension is height
when the precedence of
XmNlayoutDirection is horizontal, and
width when vertical.
XmNspatialSnapModel
Specifies how Container will position an item
within the cell layout when XmNlayoutType is
XmSPATIAL and XmNspatialStyle is XmGRID or
XmCELLS. It can have one of the following values:
XmCENTER Center the items as follows, depending
on the value of XmNentryViewType:
XmLARGEICON
The child is centered in the
cell horizontally and
baseline-aligned vertically.
XmSMALLICON
The child is centered in the
cell vertically on its
baseline and aligned with the
left or right of the cell
horizontally, depending on the
value of XmNlayoutDirection.
XmSNAPTOGRID
Position the item at the upper-left or
upper-right corner of the cell(s),
depending on the value of
XmNlayoutDirection.
Page 15 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
XmNONE Position the item according to the
position specified by XmNx and XmNy. If
the position is not within the
coordinates of the cell(s), then
position the item at the upper-left or
upper-right corner of the cell(s),
depending on the value of
XmNlayoutDirection.
XmNspatialStyle
Specifies the layout of Container items when
XmNlayoutType is XmSPATIAL. It can have one of the
following values:
XmCELLS Lays out items within a grid of same-
size cells. Each item occupies as many
cells as required to contain the item
dimensions.
XmGRID Lays out items within a grid of same-
size cells. Each item occupies only one
cell. Items that are larger than the
cell size may overlap other items.
XmNONE Lays out items according to XmNx and
XmNy.

Name Class Type Default Access
XmNentryParent XmCWidget Widget NULL CSG
XmNoutlineState XmCOutlineState unsigned char XmCOLLAPSED CSG
XmNpositionIndex XmCPositionIndex int dynamic CSG
XmNentryParent
Specifies the widget that is this item's logical
parent. A value of NULL indicates that this is a
root-level item. Parent-child information is
displayed only when the XmNlayoutPolicy is
XmOUTLINEor XmDETAIL.
XmNoutlineState
Specifies whether to display child items when
XmNlayoutPolicy is XmOUTLINE or XmDETAIL. It can
have one of the following values:
XmCOLLAPSED
Does not display child items.
XmEXPANDED
Displays child items.
XmNpositionIndex
Page 16 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
Specifies the order of items in the Container for
display. When XmNlayoutType is XmOUTLINE or
XmDETAIL, items are displayed in XmNpositionIndex
order within XmNentryParent. Items that have an
XmNentryParent resource are ignored when
XmNlayoutType is XmSPATIAL. If XmNpositionIndex
is not specified, it defaults to the
XmNpositionIndex value plus 1 of the item with the
highest XmNpositionIndex that has the same
XmNentryParent if such an item exists; otherwise,
it defaults to 0.

Callback Information
A pointer to the following structure is passed to callbacks
for XmNoutlineChangedCallback.
typedef struct
{
int reason;
XEvent * event;
Widget item;
unsigned char new_outline_state;
} XmContainerOutlineCallbackStruct;
reason Specifies the reason for the callback.
event Points to the XEvent that triggered the callback.
It can be NULL.
item Specifies the container item affected by the
event.
new_outline_state
Specifies the next XmNoutlineState for item. The
user can change this value in the callback.
A pointer to the following structure is passed to callbacks
for XmNdefaultActionCallback and XmNselectionCallback.
typedef struct
{
int reason;
XEvent * event;
WidgetList selected_items;
int selected_item_count;
unsigned char auto_selection_type;
} XmContainerSelectCallbackStruct;
reason Specifies the reason for the callback. It
Page 18 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
corresponds to the XmNselectionPolicy at the time
the selection was made, or indicates that the
default action should be taken.
event Points to the XEvent that triggered the callback.
It can be NULL.
selected_items
Specifies a list of items selected at the time of
the event that caused the callback. The
selected_items field points to a temporary storage
space that is reused after the callback is
finished. Therefore, if an application needs to
save the selected list, it should copy the list
into its own data space.
selected_item_count
Specifies the number of items in the
selected_items list. This number must be positive
or 0 (zero).
autoselectiontype
Indicates the cause of the selection when
XmNautomaticSelection is XmAUTOSELECT. Valid
values are the following:
XmAUTOUNSET
Returned when XmNautomaticSelection is
XmNOAUTOSELECT.
XmAUTOBEGIN
Indicates the beginning of automatic
selection.
XmAUTOMOTION
Indicates that there is a button drag
selection.
XmAUTOCANCEL
Indicates that the new selection is
canceled.
XmAUTONOCHANGE
Indicates that the currently selected
item matches the initial item.
XmAUTOCHANGE
Indicates that the currently selected
item does not match the initial item.
A pointer to the following structure is passed to the
XmNconvertCallback procedures:
Page 19 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
typedef struct
{
int reason;
XEvent *event;
Atom selection;
Atom target;
XtPointer source_data;
XtPointer location_data;
int flags;
XtPointer parm;
int parm_format;
unsigned long parm_length;
int status;
XtPointer value;
Atom type;
int format;
unsigned long length;
} XmConvertCallbackStruct;
reason Indicates why the callback was invoked.
event Points to the XEvent that triggered the callback.
It can be NULL.
selection Indicates the selection for which conversion is
being requested. Possible values are CLIPBOARD,
PRIMARY, SECONDARY, and MOTIFDROP.
target Indicates the conversion target.
source_data
Contains information about the selection source.
When the selection is MOTIFDROP, source_data is
the DragContext. Otherwise, it is NULL.
locationdata
Contains information about the location of data to
be converted. If the value is NULL, the data to
be transferred consists of the widget's current
selection. Otherwise, it is the widget ID of the
item being transferred, or the widget ID of the
Container if all items are being transferred.
flags Indicates the status of the conversion. Following
are the possible values:
XmCONVERTINGNONE
This flag is currently unused.
XmCONVERTINGPARTIAL
The target widget was able to be
converted, but some data was lost.
Page 20 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
XmCONVERTINGSAME
The conversion target is the source of
the data to be transferred.
XmCONVERTINGTRANSACT
This flag is currently unused.
parm Contains parameter data for this target. If no
parameter data exists, the value is NULL.
When selection is CLIPBOARD and target is
MOTIFCLIPBOARDTARGETS or
MOTIFDEFERREDCLIPBOARDTARGETS, the value is
the requested operation (XmCOPY, XmMOVE, or
XmLINK).
parm_format
Specifies whether the data in parm should be
viewed as a list of char, short, or long
quantities. Possible values are 0 (when parm is
NULL), 8 (when the data in parm should be viewed
as a list of chars), 16 (when the data in parm
should be viewed as a list of shorts), or 32 (when
the data in parm should be viewed as a list of
longs). Note that parm_format symbolizes a data
type, not the number of bits in each list element.
For example, on some machines, a parm_format of 32
means that the data in parm should be viewed as a
list of 64-bit quantities, not 32-bit quantities.
parm_length
Specifies the number of elements of data in parm,
where each element has the size specified by
parm_format. When parm is NULL, the value is 0.
status An IN/OUT member that specifies the status of the
conversion. The initial value is
XmCONVERTDEFAULT. The callback procedure can set
this member to one of the following values:
XmCONVERTDEFAULT
The widget class conversion procedure,
if any, is called after the callback
procedures return. If the widget class
conversion procedure produces any data,
it overwrites the data provided by the
callback procedures in the valuemember.
XmCONVERTMERGE
The widget class conversion procedure,
if any, is called after the callback
procedures return. If the widget class
Page 21 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
conversion procedure produces any data,
it appends its data to the data provided
by the callback procedures in the value
member. This value is intended for use
with targets that result in lists of
data, such as TARGETS.
XmCONVERTDONE
The callback procedure has successfully
finished the conversion. The widget
class conversion procedure, if any, is
not called after the callback procedures
return.
XmCONVERTREFUSE
The callback procedure has terminated
the conversion process without
completing the requested conversion.
The widget class conversion procedure,
if any, is not called after the callback
procedures return.
value An IN/OUT parameter that contains any data that
the callback procedure produces as a result of the
conversion. The initial value is NULL. If the
callback procedure sets this member, it must
ensure that the type, format, and length members
correspond to the data in value. The callback
procedure is responsible for allocating, but not
for freeing, memory when it sets this member.
type An IN/OUT parameter that indicates the type of the
data in the value member. The initial value is
INTEGER.
format An IN/OUT parameter that specifies whether the
data in value should be viewed as a list of char,
short, or long quantities. The initial value is
8. The callback procedure can set this member to
8 (for a list of char), 16 (for a list of short),
or 32 (for a list of long).
length An IN/OUT member that specifies the number of
elements of data in value, where each element has
the size symbolized by format. The initial value
is 0 (zero).
A pointer to the following callback structure is passed to
the XmNdestinationCallback procedures:
typedef struct
{
Page 22 (printed 1/22/99)

int reason;
XEvent *event;
Atom selection;
XtEnum operation;
int flags;
XtPointer transfer_id;
XtPointer destination_data;
XtPointer location_data;
Time time;
} XmDestinationCallbackStruct;
reason Indicates why the callback was invoked.
event Points to the XEvent that triggered the callback.
It can be NULL.
selection Indicates the selection for which data transfer is
being requested. Possible values are CLIPBOARD,
PRIMARY, SECONDARY, and MOTIFDROP.
operation Indicates the type of transfer operation
requested.
⊕ When the selection is PRIMARY, possible
values are XmMOVE, XmCOPY, and XmLINK.
⊕ When the selection is SECONDARY or
CLIPBOARD, possible values are XmCOPY and
XmLINK.
⊕ When the selection is MOTIFDROP, possible
values are XmMOVE, XmCOPY, XmLINK, and
XmOTHER. A value of XmOTHER means that the
callback procedure must get further
information from the
XmDropProcCallbackStruct in the
destination_data member.
flags Indicates whether or not the destination widget is
also the source of the data to be transferred.
Following are the possible values:
XmCONVERTINGNONE
The destination widget is not the source
of the data to be transferred.
XmCONVERTINGSAME
The destination widget is the source of
the data to be transferred.
transferid
Serves as a unique ID to identify the transfer
Page 23 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
transaction.
destination_data
Contains information about the destination. When
the selection is MOTIFDROP, the callback
procedures are called by the drop site's
XmNdropProc, and destination_datais a pointer to
the XmDropProcCallbackStruct passed to the
XmNdropProc procedure. When the selection is
SECONDARY, destination_data is an Atom
representing a target recommmended by the
selection owner for use in converting the
selection. Otherwise, destination_data is NULL.
locationdata
Contains information about the location where data
is to be transferred. The value is always NULL
when the selection is SECONDARY or CLIPBOARD. If
the value is NULL, the data is to be inserted at
the widget's cursor position. Otherwise, the
value is a pointer to an XPoint structure
containing the x and y coordinates at the location
where the data is to be transferred. Once
XmTransferDone procedures start to be called,
locationdata will no longer be stable.
time Indicates the time when the transfer operation
began.
Translations
The XmContainer translations are listed below.
The following key names are listed in the X standard key
event translation table syntax. This format is the one used
by Motif to specify the widget actions corresponding to a
given key. A brief overview of the format is provided under
VirtualBindings(3). For a complete description of the

The Container button event translations are modified when
Display's XmNenableBtn1Transfer resource does not have a
value of XmOFF (in other words, it is either
XmBUTTON2_TRANSFER or XmBUTTON2_ADJUST). This option allows
the actions for selection and transfer to be integrated on
<Btn1>, and the actions for extending the selection can be
bound to <Btn2>. The actions for <Btn1> that are defined in
the preceding list still apply when the <Btn1> event occurs
over text that is not selected. The following actions apply
when the <Btn1> event occurs over text that is selected:
~c ~s ~m ~a <Btn1Down>:

Action Routines
The Container action routines are described below. The
current selections are always shown with the background
color specified by the XmNselectColor resource.
ContainerActivate():
This action calls XmNdefaultActionCallbackwith
reason XmCRDEFAULTACTION.
ContainerBeginExtend():
Simply returns if XmNselectionPolicy is
XmSINGLESELECT or XmBROWSESELECT. Simply
returns if XmNlayoutType is XmSPATIAL.
Otherwise, this action sets the selection state of
all items between the anchor item and the item
under the pointer to the selection state of the
anchor item. The location cursor is moved to the
item under the pointer. If XmNautomaticSelection
is XmAUTOSELECT, the XmNselectionCallback(s) is
called with either XmCRMULTIPLESELECTor
XmCREXTENDEDSELECT as the reason depending on
Page 28 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
XmNselectionPolicy, and with
autoselectiontypeXmAUTOCHANGE.
ContainerBeginSelect():
If this is a second ContainerBeginSelect() action
that has occurred within the time specified by the
display's multiclick time, this action calls
XmNdefaultActionCallback with reason
XmCRDEFAULTACTION and returns.
Otherwise, processing depends on the value of
XmNselectionPolicyas follows:
XmSINGLESELECT
This action deselects all items and
toggles the item (if any) under the
pointer.
XmBROWSESELECT
This action deselects all items and
toggles the item (if any) under the
pointer. This item is now the anchor
item for further selection. If
XmNautomaticSelection is XmAUTOSELECT
and a change in any item's selection
state is made, the
XmNselectionCallback(s) is called with
reason XmCRBROWSESELECT and
autoselectiontype XmAUTOBEGIN.
XmMULTIPLESELECT
If the pointer is over an item and
XmNselectionTechnique is not XmMARQUEE,
this action toggles the selection state
of that item. The item becomes the
anchor item for further selection. If
XmNselectionTechnique is XmMARQUEE,
XmMARQUEEEXTENDSTART, or
XmMARQUEEEXTENDBOTH, this action sets
the start point for the Marquee
rectangle. If XmNselectionTechnique is
XmMARQUEEEXTENDSTART or
XmMARQUEEEXTENDBOTH and the pointer is
over an item, this action draws the
Marquee rectangle around the item. If
XmNautomaticSelection is XmAUTOSELECT,
the XmNselectionCallback(s) is called
with reason XmCRMULTIPLESELECT and
autoselectiontype XmAUTOBEGIN.
XmEXTENDEDSELECT
All items are first deselected.
Page 29 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
Processing is then identical to the case
where XmNselectionPolicy is
XmMULTIPLESELECT, except that
XmCREXTENDEDSELECT is the callback
reason given if XmNselectionCallback is
called.
ContainerBeginToggle():
Simply returns if XmNselectionPolicy is
XmSINGLESELECT or XmBROWSESELECT.
Otherwise, if the pointer is over an item and
XmNselectionTechnique is not XmMARQUEE, this
action toggles the selection state of that item.
The item becomes the anchor item for further
selection. If XmNselectionTechnique is XmMARQUEE,
XmMARQUEEEXTENDSTART, or
XmMARQUEEEXTENDBOTHthis action sets the start
point for the Marquee rectangle. If
XmNselectionTechnique is XmMARQUEEEXTENDSTART or
XmMARQUEEEXTENDBOTH and the pointer is over an
item, this action draws the Marquee rectangle
around the item. If XmNautomaticSelection is
XmAUTOSELECT, the XmNselectionCallback(s) is
called with either XmCRMULTIPLESELECTor
XmCREXTENDEDSELECT as the reason, depending on
XmNselectionPolicy, and with autoselectiontype
XmAUTOBEGIN.
ContainerButtonMotion():
Processing depends on the value of
XmNselectionPolicy, as follows:
XmSINGLESELECT
This action simply returns to the
caller.
XmBROWSESELECT
Simply returns if this action follows a
ContainerBeginExtend()action or
ContainerBeginToggle() action.
If the pointer is no longer over the
current anchor item, this action toggles
the current anchor item and then toggles
the item under the pointer (if any) and
makes it the new anchor item for further
processing. If XmNautomaticSelection is
XmAUTOSELECT and a change in any item's
selection state is made, the
XmNselectionCallback(s) is called with
reason XmCRBROWSESELECT and
Page 30 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
autoselectiontype XmAUTOMOTION.
XmMULTIPLESELECT
If a previous action has set a Marquee
rectangle start point, this action draws
the Marquee rectangle between the
current pointer position and the Marquee
start point. If the
XmNselectionTechnique is
XmMARQUEEEXTENDBOTH and the pointer is
over an item, the end point of the
Marquee rectangle is extended to include
the item. The selection states of all
items within the Marquee rectangle are
toggled to match the state of the anchor
item.
If no Marquee rectangle start point is
set and the pointer is over an item,
processing depends on the XmNlayoutType
resource. The anchor item from the
previous action is used. If
XmNlayoutType is XmSPATIAL, the
selection state of the item under the
pointer is toggled to match the
selection state of the anchor item. If
XmNlayoutType is XmOUTLINE or XmDETAIL,
the selection state of all items between
the anchor item and the item under the
pointer are toggled to match the
selection state of the anchor item.
If XmNautomaticSelection is
XmAUTOSELECT and a change in any item's
selection state is made, the
XmNselectionCallback(s) is called with
reason XmCRMULTIPLESELECTand
autoselectiontype XmAUTOMOTION.
XmEXTENDEDSELECT
Processing is identical to the case
where XmNselectionPolicy is
XmMULTIPLESELECT, except that
XmCREXTENDEDSELECT is the callback
reason given if XmNselectionCallback is
called.
ContainerCancel():
If a selection is in progress, this action
restores selection states of all items to their
state before the selection began. If
XmNautomaticSelection is True and a change in any
Page 31 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
item's selection state is made, the
XmNselectionCallback is called with reason
XmCRBROWSESELECT, XmMULTIPLESELECT, or
XmCREXTENDEDSELECTdepending on the
XmNselectionPolicy resource and
autoselectiontypeXmAUTOCANCEL.
ContainerDeselectAll():
This action deselects all items and calls
XmNselectionCallback with reason depending on
XmNselectionPolicy.
ContainerEndExtend():
Simply returns if XmNselectionPolicy is
XmSINGLESELECT or XmBROWSESELECT. Simply
returns if XmNlayoutType is XmSPATIAL.
Otherwise, if XmNautomaticSelection is
XmNOAUTOSELECT, XmNselectionCallback(s) is
called with either XmCRMULTIPLESELECTor
XmCREXTENDEDSELECT as the reason depending on
XmNselectionPolicy. If XmNautomaticSelection is
XmAUTOSELECT and no change is made in any item's
selection state by this action,
XmNselectionCallback(s) is called with either
XmCRMULTIPLESELECTor XmCREXTENDEDSELECT as the
reason depending on XmNselectionPolicy and
autoselectiontype XmAUTOCHANGE. If
XmNautomaticSelection is XmAUTOSELECT and this
action makes no change in any item's selection
state, XmNselectionCallback(s) is called with
either XmCRMULTIPLESELECTor XmCREXTENDEDSELECT
as the reason depending on XmNselectionPolicy and
autoselectiontype XmAUTONOCHANGE.
ContainerEndSelect():
Processing depends on the value of
XmNselectionPolicy, as follows:
XmSINGLESELECT
This action calls
XmNselectionCallbackwith reason
XmCRSINGLESELECT.
XmBROWSESELECT
If the pointer is no longer over the
current anchor item, this action toggles
the current anchor item and then toggles
the item under the pointer (if any). If
XmNautomaticSelection is
XmNOAUTOSELECT, the
XmNselectionCallback(s) is called with
Page 32 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
reason XmCRBROWSESELECT. If
XmNautomaticSelection is XmAUTOSELECT
and a change in any item's selection
state is made, XmNselectionCallback(s)
is called with reason XmCRBROWSESELECT
and autoselectiontype XmAUTOCHANGE.
If XmNautomaticSelection is
XmAUTOSELECT and no change is made in
any item's selection state by this
action, XmNselectionCallback(s) is
called with reason XmCRBROWSESELECT
and autoselectiontype
XmAUTONOCHANGE.
XmMULTIPLESELECT
This action first performs the same
processing as the
ContainerButtonMotion()action, except
that XmNselectionCallback is not called.
If XmNautomaticSelection is
XmNOAUTOSELECT, the
XmNselectionCallback(s) is called with
reason XmCRMULTIPLESELECT. If
XmNautomaticSelection is XmAUTOSELECT
and a change in any item's selection
state is made, the
XmNselectionCallback(s) is called with
reason XmCRMULTIPLESELECT and
autoselectiontype XmAUTOCHANGE. If
XmNautomaticSelection is XmAUTOSELECT
and this action makes no change in any
item's selection state,
XmNselectionCallback(s) is called with
reason XmCRMULTIPLESELECT and
autoselectiontype XmAUTONOCHANGE.
XmEXTENDEDSELECT
This action first performs the same
processing as the
ContainerButtonMotion()action, except
that XmNselectionCallback is not called.
If XmNautomaticSelection is
XmNOAUTOSELECT, the
XmNselectionCallback(s) is called with
reason XmCREXTENDEDSELECT. If
XmNautomaticSelection is XmAUTOSELECT
and a change in any item's selection
state is made, XmNselectionCallback(s)
is called with reason
XmCREXTENDEDSELECT and
autoselectiontype XmAUTOCHANGE. If
XmNautomaticSelection is XmAUTOSELECT
Page 33 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
and this action makes no change in any
item's selection state,
XmNselectionCallback(s) is called with
reason XmCREXTENDEDSELECT and
autoselectiontype XmAUTONOCHANGE.
ContainerEndToggle():
Simply returns if XmNselectionPolicy is
XmSINGLESELECT or XmBROWSESELECT. If
XmNselectionPolicy is XmMULTIPLESELECT or
XmEXTENDEDSELECT, this action performs the same
processing as the ContainerEndSelect() action.
ContainerEndTransfer()::
If the elapsed time since a
ContainerStartTransfer()action has occurred
exceeds the time span specified by the display's
multiclick time, this action returns.
Otherwise, the ContainerPrimaryCopy(),
ContainerPrimaryLink(), or ContainerPrimaryMove()
action is invoked, depending on the value of the
operation parameter saved by
ContainerStartTransfer().
ContainerExpandOrCollapse(Left|Right|Collapse|Expand):
This action changes the value of the
XmNoutlineState of the current focus widget. If
the argument value is Collapse or Left, the
XmNoutlineState resource value is set to
XmCOLLAPSED. If the argument value is Expandor
Right, the XmNoutlineState resource value is set
to XmEXPANDED.
If the argument is Left or Right and the layout is
right to left, then the setting of the
XmNoutlineState value is reversed from that
described in the preceding paragraph.
Simply returns if XmNlayoutType is XmSPATIAL.
ContainerExtend():
Processing depends on the value of
XmNselectionPolicy, as follows:
If the selection policy is XmSINGLESELECT or
XmBROWSESELECT, this action returns. If
XmNlayoutType is XmSPATIAL, this action returns.
If the selection policy is XmMULTIPLESELECT, this
action sets the selection state of all items
between the anchor item and the location cursor to
Page 34 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
the selection state of the anchor item.
If the selection policy is XmEXTENDEDSELECT and
the Container is in Normal Mode, this action
deselects all items and selects all items between
the anchor item and the location cursor. If the
selection policy is XmEXTENDEDSELECT and the
Container is in Add Mode, this action sets the
selection state of all items between the anchor
item and the location cursor to the selection
state of the anchor item.
XmNselectionCallback is called with reason
XmCRMULTIPLESELECTor XmCREXTENDEDSELECT
depending on XmNselectionPolicy.
ContainerExtendCursor(Left|Right|Up|Down):
Processing depends on the value of
XmNselectionPolicy, as follows:
If the selection policy is XmSINGLESELECT or
XmBROWSESELECT, this action returns. If
XmNlayoutType is XmSPATIAL, this action returns.
This action moves the location cursor one item in
the indicated direction, if possible. If the
value of the argument string is First or Last,
this action moves the location cursor to the
indicated item. For other values of the argument
string, the location cursor is not affected.
If the selection policy is XmMULTIPLESELECT, this
action sets the selection state of all items
between the anchor item and the location cursor to
the selection state of the anchor item.
If the selection policy is XmEXTENDEDSELECT and
the Container is in Normal Mode, this action
deselects all items and selects all items between
the anchor item and the location cursor. If the
selection policy is XmEXTENDEDSELECT and the
Container is in Add Mode, this action sets the
selection state of all items between the anchor
item and the location cursor to the selection
state of the anchor item.
XmNselectionCallback is called with reason
XmCRMULTIPLESELECTor XmCREXTENDEDSELECT
depending on XmNselectionPolicy.
ContainerHandleBtn1Down(string)
When Display's XmNenableBtn1Transfer resource is
Page 35 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
not XmOFF, the actions for selection and transfer
are integrated on <Btn1>. If the pointer is over
an unselected item or background, the item is
first selected before the transfer is started.
Otherwise, if the item is already selected, the
transfer is started. The value of string can be
one of the following actions:
⊕ ContainerBeginSelect,Copy
⊕ ContainerBeginToggle,Copy
⊕ ContainerNoop,Link
⊕ ContainerBeginExtend,Move
ContainerHandleBtn1Motion(string)
When Display's XmNenableBtn1Transfer resource is
not XmOFF, the actions for selection and transfer
are integrated on <Btn1>. When this action is
invoked, and a selection is in progress, a drag is
performed. Otherwise, the default action as
specified in string is performed. The value of
stringcan be ContainerButtonMotion.
ContainerHandleBtn1Up(string)
If a Button 1 transfer was in progress, then when
this action is invoked, that transfer is
cancelled. Otherwise, the default action as
specified in string is performed. The value of
stringcan be one of the following actions:
⊕ ContainerEndSelect
⊕ ContainerEndToggle
⊕ ContainerEndExtend
ContainerHandleBtn2Down(string)
When Display's XmNenableBtn1Transfer resource has
a value of XmBUTTON2_ADJUST, the actions for
extending selection are bound on <Btn2>.
Otherwise, the action that is performed depends on
the value of string, which can be one of the
following actions:
⊕ ContainerStartTransfer,Copy
⊕ ContainerStartTransfer,Link
⊕ ContainerStartTransfer,Move
Page 36 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
ContainerHandleBtn2Motion(string)
When Display's XmNenableBtn1Transfer resource is
not XmBUTTON2_ADJUST, and a selection is in
progress, a drag is performed. Otherwise, the
default action that is performed depends on the
value of string, which can be
ContainerButtonMotion.
ContainerHandleBtn2Up(string)
When Display's XmNenableBtn1Transfer resource has
a value of XmBUTTON2_ADJUST, this action ends an
extend. Otherwise, the action that is performed
depends on the value of string, which can be
ContainerEndTransfer.
ContainerMoveCursor(Left|Right|Up|Down|First|Last):
If the argument is Left, Right, Up, or Down, this
action moves the location cursor one item in the
indicated direction, if possible. If the value of
the argument string is First or Last, this action
moves the location cursor to the indicated item.
Any other arguments are ignored.
If XmNselectionPolicy is XmBROWSESELECT, or if
XmNselectionPolicy is XmEXTENDEDSELECT and the
Container is in Normal Mode, this action deselects
all items, selects the item at the location
cursor, and calls XmNselectionCallback with the
reason depending on XmNselectionPolicy.
ContainerPrimaryCopy():
This action requests that primary selection data
be copied to the Container. This action calls the
XmNdestinationCallback procedures for the PRIMARY
selection and the XmCOPY operation. By default,
the Container does not do any transfer, and
copying the selection is the responsibility of the
XmNdestinationCallbackprocedures.
ContainerPrimaryLink():
This action requests that primary selection data
be linked to the Container. This action calls the
XmNdestinationCallback procedures for the PRIMARY
selection and the XmLINK operation. By default,
the Container does not do any transfer, and
linking the selection is the responsibility of the
XmNdestinationCallbackprocedures.
ContainerPrimaryMove():
This action requests that primary selection data
be copied to the Container and deleted from the
primary source. This action calls the
Page 37 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
XmNdestinationCallback procedures for the PRIMARY
selection and the XmMOVE operation. By default,
the Container does not do any transfer, and moving
the selection is the responsibility of the
XmNdestinationCallbackprocedures. If the transfer
is successful, this action then calls the
selection owner's XmNconvertCallback procedures
for the PRIMARYselection and the DELETE target.
ContainerSelect():
Processing depends on the value of
XmNselectionPolicy, as follows:
If the selection policy is XmSINGLESELECT or
XmBROWSESELECT, this action deselects all items
and selects the item at the location cursor.
If the selection policy is XmMULTIPLESELECT, this
action toggles the selection state of the item at
the location cursor. This item becomes the anchor
item for further selections.
If the selection policy is XmEXTENDEDSELECT and
the Container is in Normal Mode, this action
deselects all items and selects the item at the
location cursor. If the selection policy is
XmEXTENDEDSELECT and the Container is in Add
Mode, this action toggles the selection state of
the item at the location cursor. The
selected/toggled item becomes the anchor item for
further selections.
XmNselectionCallback is called with the reason
depending on XmNselectionPolicy.
ContainerSelectAll():
If XmNselectionPolicy is XmSINGLESELECT or
XmBROWSESELECT, this action deselects all items
and selects the item at the location cursor
position.
If XmNselectionPolicy is XmMULTIPLESELECTor
XmEXTENDEDSELECT, this action selects all items.
XmNselectionCallback is called with the reason
depending on the value of XmNselectionCallback.
ContainerStartTransfer(Copy|Move|Link):
This action saves the event and the operation
specified in the argument string for use by
subsequent actions. If no ContainerEndTransfer()
actions occur within the time span specified by
Page 38 (printed 1/22/99)
XmContainer(3X) UNIX System V XmContainer(3X)
the display's multiclick time and if
XmNlayoutTypeis XmSPATIAL, this action creates a
DragContext and starts a drag transfer by using
string to specify the transfer operation. If no
argument string is specified, Copy is the default
value.
Unless default drag and drop behavior has been
overridden by a XmNconvertCallback procedure, if
the drop operation occurs within the Container,
then the item(s) being dragged are relocated at
the position of the drop operation. If the item
targeted by the Drag operation is not in the
selected state, then only that item is moved. If
the item is in the selected state, however, all
items in the selected state are moved.
ContainerToggleMode():
If XmNselectionPolicy is XmEXTENDEDSELECT, this
action toggles the Container between Normal Mode
and Add Mode.
Additional Behavior
The Container widget has the following additional behavior:
<Btn1Down>(2+)
If a button click is followed by another button
click within the time span specified by the
display's multiclick time, the Container
interprets that as a double-click and calls the
XmNdefaultActionCallback callbacks.
<FocusIn>:
If the focus policy is explicit, sets the focus
and draws the location cursor.
<FocusOut>:
If the focus policy is explicit, removes the focus
and erases the location cursor.
