DESCRIPTION
A widget holding the XmQTcontainerItem trait can serve as a
child to a widget holding the XmQTcontainer trait.
XmIconGadget is the only standard Motif class holding the
XmQTcontainerItem trait. XmContainer is the only standard
Motif widget that examines its children for this trait.
The setValues Trait Method
void setValues(
Widget containerChildWidget,
XmContainerItemData containerItemData);
A container widget (such as XmContainer) calls the setValues
trait method of its containerChildWidgetin order to set
certain visual properties.
containerChildWidget
Specifies the container child widget that is
holding this trait.
containerItemData
Page 1 (printed 1/22/99)
XmQTcontainerItem(3X) UNIX System V XmQTcontainerItem(3X)
Specifies an XmContainerItemData structure. This
structure holds five fields, but only the first
three fields are meaningful to the setValues trait
method. Following is a description of those three
fields:
valueMask Specifies a bit mask. Each bit in the
bit mask symbolizes a visual property
affected by the setValues trait method.
If a particular bit is set to 1,
setValues modifies the associated visual
property. If this same bit holds a 0,
setValues does not modify the associated
visual property. To help you set bits,
the ContItemT.h header file provides
three relevant constants.
ContItemViewType
Sets the view_type visual
property bit to 1.
ContItemVisualEmphasis
Sets the setValues visual
property bit to 1.
ContItemAllValid
Sets both visual property bits
to 1.
view_type Specifies the view type of widget. For
example, when XmContainer calls
setValues, it passes a view_type value
of either XmLARGEICON or XmSMALLICON.
(See the XmIconGadget(3) reference page
for a description of XmLARGEICON and
XmSMALLICON.)
visual_emphasis
Specifies the visual emphasis of widget.
For example, when XmContainer calls
setValues, it passes a visualEmphasis
value of either XmSELECTED or
XmNOTSELECTED. See the XmIconGadget(3)
reference page for a description of
XmSELECTED and XmNOTSELECTED.
The getValues Trait Method
void getValues(
Widget containerChildWidget,
XmContainerItemData containerItemData);
A container widget calls the getValues trait method of its
Page 2 (printed 1/22/99)
XmQTcontainerItem(3X) UNIX System V XmQTcontainerItem(3X)
containerChildWidget to determine what visual properties the
containerChildWidget provides.
containerChildWidget
Specifies the child widget that is holding this
trait.
containerItemData
Specifies an XmContainerItemData structure. This
structure holds the following five fields:
valueMask Specifies a bit mask. Each bit in the
bit mask symbolizes a visual property
returned by the getValues trait method.
If the caller sets a particular bit to
1, getValues returns meaningful
information about the associated visual
property. However, if the caller places
a 0 in this same bit, then getValues
does not return meaningful information
about the associated visual property. In
short, the valueMask lets the caller
specify the visual properties that it is
interested in. To help you set bits,
the ContItemT.h header file provides the
following five constants:
ContItemViewType
Sets the view_type visual
property bit to 1.
ContItemVisualEmphasis
Sets the visual_emphasis
visual property bit to 1.
ContItemIconWidth
Sets the iconwidth visual
property bit to 1.
ContItemDetailCount
Sets the detail_count visual
property bit to 1.
ContItemAllValid
Sets all four visual property
bits to 1.
view_type Returns the view type of
childContainerWidget. If XmContainer is
managing containerChildWidget,
XmContainer expects that the returned
value will be either XmLARGEICON or
Page 3 (printed 1/22/99)
XmQTcontainerItem(3X) UNIX System V XmQTcontainerItem(3X)
XmSMALLICON. See the XmIconGadget(3)
reference page for a description of
these two values.
visual_emphasis
Returns the visual emphasis of
childContainerWidget. If XmContainer is
managing widget, XmContainer expects
that the returned value will be either
XmSELECTED or XmNOTSELECTED. (See the
XmIconGadget(3) reference page for a
description of these two values.)
icon_width
Returns the width of the icon. (This
width will not include the width of any
associated detail strings.)
detail_count
Returns the number of details strings in
this container child.
