XmToggleButton(3X) SDK X11 R4.11MU05 XmToggleButton(3X)
NAME
XmToggleButton--The ToggleButton widget class
SYNOPSIS
#include <Xm/ToggleB.h>
DESCRIPTION
ToggleButton sets nontransitory state data within an application.
Usually this widget consists of an indicator (square or diamond) with
either text or a pixmap on one side of it. However, it can also
consist of just text or a pixmap without the indicator.
The toggle graphics display a 1-of-many or N-of-many selection state.
When a toggle indicator is displayed, a square indicator shows an N-
of-many selection state and a diamond indicator shows a 1-of-many
selection state.
ToggleButton implies a selected or unselected state. In the case of
a label and an indicator, an empty indicator (square or diamond
shaped) indicates that ToggleButton is unselected, and a filled
indicator shows that it is selected. In the case of a pixmap toggle,
different pixmaps are used to display the selected/unselected states.
The default behavior associated with a ToggleButton in a menu depends
on the type of menu system in which it resides. By default, BSelect
controls the behavior of the ToggleButton. In addition, BMenu
controls the behavior of the ToggleButton if it resides in a
PopupMenu system. The actual mouse button used is determined by its
RowColumn parent.
To accommodate the toggle indicator when created, Label's resource
XmNmarginLeft may be increased.
Classes
ToggleButton inherits behavior and resources from Core, XmPrimitive,
and XmLabel Classes.
The class pointer is xmToggleButtonWidgetClass.
The class name is XmToggleButton.
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 .Xdefaults
file, 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 if 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).

XmNarmCallback
Specifies the list of callbacks called when the
ToggleButton is armed. To arm this widget, press the
active mouse button while the pointer is inside the
ToggleButton. For this callback, the reason is XmCRARM.
XmNdisarmCallback
Specifies the list of callbacks called when ToggleButton is
disarmed. To disarm this widget, press and release the
active mouse button while the pointer is inside the
ToggleButton. This widget is also disarmed when the user
moves out of the widget and releases the mouse button when
the pointer is outside the widget. For this callback, the
reason is XmCRDISARM.
XmNfillOnSelect
Fills the indicator with the color specified in
XmNselectColor and switches the top and bottom shadow
colors when set to True. Otherwise, it switches only the
top and bottom shadow colors. The default is set to the
value of XmNindicatorOn. When XmNindicatorOn is False, and
XmNfillOnSelect is set explicitly to True, the background
is filled with the color specified by XmNselectColor.
XmNindicatorOn
Specifies that a toggle indicator is drawn to one side of
the toggle text or pixmap when set to True. When set to
False, no space is allocated for the indicator, and it is
not displayed. If XmNindicatorOn is True, the indicator
shadows are switched when the button is selected or
unselected, but, any shadows around the entire widget are
not switched. However, if XmNindicatorOn is False, any
shadows around the entire widget are switched when the
toggle is selected or unselected.
XmNindicatorSize
Sets the size of the indicator. If no value is specified,
the size of the indicator is based on the size of the label
string or pixmap. If the label string or pixmap changes,
the size of the indicator is recomputed based on the size
of the label string or pixmap. Once a value has been
specified for XmNindicatorSize, the indicator has that
size, regardless of the size of the label string or pixmap,
until a new value is specified.
XmNindicatorType
Specifies if the indicator is a 1-of or N-of indicator.
For the 1-of indicator, the value is XmONEOFMANY. For
the N-of indicator, the value is XmNOFMANY. The N-of-
many indicator is square. The 1-of-many indicator is
diamond shaped. This resource specifies only the visuals
and does not enforce the behavior. When the ToggleButton
is in a RadioBox, the default is XmONEOFMANY; otherwise,
the default is XmNOFMANY.
XmNselectColor
Allows the application to specify what color fills the
center of the square or diamond-shaped indicator when it is
set. If this color is the same as either the top or the
bottom shadow color of the indicator, a one-pixel-wide
margin is left between the shadows and the fill; otherwise,
it is filled completely. This resource's default for a
color display is a color between the background and the
bottom shadow color. For a monochrome display, the default
is set to the foreground color. To set the background of
the button to XmNselectColor when XmNindicatorOn is False,
the value of XmNfillOnSelect must be explicitly set to
True.
XmNselectInsensitivePixmap
Specifies a pixmap used as the button face when the
ToggleButton is selected and the button is insensitive if
the Label resource XmNlabelType is set to XmPIXMAP. If the
ToggleButton is unselected and the button is insensitive,
the pixmap in XmNlabelInsensitivePixmap is used as the
button face. If no value is specified for
XmNlabelInsensitivePixmap, that resource is set to the
value specified for XmNselectInsensitivePixmap.
XmNselectPixmap
Specifies the pixmap to be used as the button face if
XmNlabelType is XmPIXMAP and the ToggleButton is selected.
When the ToggleButton is unselected, the pixmap specified
in Label's XmNlabelPixmap is used. If no value is
specified for XmNlabelPixmap, that resource is set to the
value specified for XmNselectPixmap.
XmNset Represents the state of the ToggleButton. A value of false
indicates that the ToggleButton is not set. A value of
true indicates that the ToggleButton is set. Setting this
resource sets the state of the ToggleButton.
XmNspacing
Specifies the amount of spacing between the toggle
indicator and the toggle label (text or pixmap).
XmNvalueChangedCallback
Specifies the list of callbacks called when the
ToggleButton value is changed. To change the value, press
and release the active mouse button while the pointer is
inside the ToggleButton. This action also causes this
widget to be disarmed. For this callback, the reason is
XmCRVALUECHANGED.
XmNvisibleWhenOff
Indicates that the toggle indicator is visible in the
unselected state when the Boolean value is True. When the
ToggleButton is in a menu, the default value is False.
When the ToggleButton is in a RadioBox, the default value
is True.
Inherited Resources
ToggleButton inherits behavior and resources from the following
superclasses. For a complete description of each resource, refer to

Callback Information
A pointer to the following structure is passed to each callback:
typedef struct
{
int reason;
XEvent * event;
int set;
} XmToggleButtonCallbackStruct;
reason Indicates why the callback was invoked
event Points to the XEvent that triggered the callback
set Reflects the ToggleButton's current state when the callback
occurred, either True (selected) or False (unselected)
Translations
XmToggleButton includes translations from Primitive. Additional
XmToggleButton translations for buttons not in a menu system are
listed below. These translations may not directly correspond to a
translation table.
Note that altering translations in #override or #augment mode is
undefined.
BDragPress: ProcessDrag()
BSelect Press: Arm()
BSelect Release:Select()
Disarm()
KHelp: Help()
KSelect: ArmAndActivate()
XmToggleButton inherits menu traversal translations from XmLabel.
Additional XmToggleButton translations for ToggleButtons in a menu
system are listed below. In a Popup menu system, BMenu also performs
the BSelect actions. These translations may not directly correspond
to a translation table.
BSelect Press: BtnDown()
BSelect Release:BtnUp()
KHelp: Help()
KActivate: ArmAndActivate()
KSelect: ArmAndActivate()
MAny KCancel: MenuShellPopdownOne()
Action Routines
The XmToggleButton action routines are described below:
Arm(): If the button was previously unset, this action does the
following: If XmNindicatorOn is True, it draws the
indicator shadow so that the indicator looks pressed; if
XmNfillOnSelect is True, it fills the indicator with the
color specified by XmNselectColor. If XmNindicatorOn is
False, it draws the button shadow so that the button looks
pressed. If XmNlabelType is XmPIXMAP, the XmNselectPixmap
is used as the button face. Calls the XmNarmCallback
callbacks.
If the button was previously set, this action does the following: If
both XmNindicatorOn and XmNvisibleWhenOff are True, it draws the
indicator shadow so that the indicator looks raised; if
XmNfillOnSelect is True, it fills the indicator with the background
color. If XmNindicatorOn is False, it draws the button shadow so
that the button looks raised. If XmNlabelType is XmPIXMAP, the
XmNlabelPixmap is used as the button face. Calls the XmNarmCallback
callbacks.
ArmAndActivate():
If the ToggleButton was previously set, unsets it; if the
ToggleButton was previously unset, sets it.
In a menu, does the following: Unposts all menus in the menu
hierarchy. Unless the button is already armed, calls the
XmNarmCallback callbacks. Calls the XmNvalueChangedCallback and
XmNdisarmCallback callbacks.
Outside a menu, if the button was previously unset, this action does
the following: If XmNindicatorOn is True, it draws the indicator
shadow so that the indicator looks pressed; if XmNfillOnSelect is
True, it fills the indicator with the color specified by
XmNselectColor. If XmNindicatorOn is False, it draws the button
shadow so that the button looks pressed. If XmNlabelType is
XmPIXMAP, the XmNselectPixmap is used as the button face. Calls the
XmNarmCallback, XmNvalueChangedCallback, and XmNdisarmCallback
callbacks.
Outside a menu, if the button was previously set, this action does
the following: If both XmNindicatorOn and XmNvisibleWhenOff are True,
it draws the indicator shadow so that the indicator looks raised; if
XmNfillOnSelect is True, it fills the indicator with the background
color. If XmNindicatorOn is False, it draws the button shadow so
that the button looks raised. If XmNlabelType is XmPIXMAP, the
XmNlabelPixmap is used as the button face. Calls the XmNarmCallback,
XmNvalueChangedCallback, and XmNdisarmCallback callbacks.
BtnDown():
This action unposts any menus posted by the ToggleButton's
parent menu, disables keyboard traversal for the menu, and
enables mouse traversal for the menu. It draws the shadow
in the armed state and, unless the button is already armed,
calls the XmNarmCallback callbacks.
BtnUp(): This action unposts all menus in the menu hierarchy. If
the ToggleButton was previously set, unsets it; if the
ToggleButton was previously unset, sets it. It calls the
XmNvalueChangedCallback callbacks and then the
XmNdisarmCallback callbacks.
Disarm(): Calls the callbacks for XmNdisarmCallback.
Help(): In a Pulldown or Popup MenuPane, unposts all menus in the
menu hierarchy and restores keyboard focus to the widget
that had the focus before the menu system was entered.
Calls the callbacks for XmNhelpCallback if any exist. If
there are no help callbacks for this widget, this action
calls the help callbacks for the nearest ancestor that has
them.
MenuShellPopdownOne():
In a toplevel Pulldown MenuPane from a MenuBar, unposts the
menu, disarms the MenuBar CascadeButton and the MenuBar,
and restores keyboard focus to the widget that had the
focus before the MenuBar was entered. In other Pulldown
MenuPanes, unposts the menu.
In a Popup MenuPane, unposts the menu and restores keyboard focus to
the widget from which the menu was posted.
ProcessDrag():
Drags the contents of a ToggleButton label, identified by
pressing BDrag. This action creates a DragContext object
whose XmNexportTargets resource is set to "COMPOUND_TEXT"
for a label type of XmSTRING; otherwise, "PIXMAP" if the
label type is XmPIXMAP. This action is undefined for
ToggleButtons used in a menu system.
Select(): If the pointer is within the button, takes the following
actions: If the button was previously unset, sets it; if
the button was previously set, unsets it. Calls the
XmNvalueChangedCallback callbacks.
Additional Behavior
This widget has the additional behavior described below:
<EnterWindow>:
In a menu, if keyboard traversal is enabled, this action
does nothing. Otherwise, it draws the shadow in the armed
state and calls the XmNarmCallback callbacks.
If the ToggleButton is not in a menu and the cursor leaves and then
reenters the ToggleButton's window while the button is pressed, this
action restores the button's armed appearance.
<LeaveWindow>:
In a menu, if keyboard traversal is enabled, this action
does nothing. Otherwise, it draws the shadow in the
unarmed state and calls the XmNdisarmCallback callbacks.
If the ToggleButton is not in a menu and the cursor leaves the
ToggleButton's window while the button is pressed, this action
restores the button's unarmed appearance.
