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, diamond, or
round) 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, N-of-many, or 1-of-many-round
selection state. When a toggle indicator is displayed, a square
indicator shows an N-of-many selection state, a diamond-shaped
indicator shows a 1-of-many selection state, and a circle-shaped
indicator shows a 1-of-many-round selection state.
ToggleButton implies a set or unset state. In the case of a label and
an indicator, an empty indicator (square, diamond, or round) indicates
that ToggleButton is unset, and a filled indicator shows that it is
set. The indicator may be filled with a check mark, a cross, or the
select color. In the case of a pixmap toggle, different pixmaps are
used to display the set/unset states. ToggleButton can also indicate
an indeterminate state. In the case of a label and an indicator, an
indeterminate state is indicated by a stippled flat box. In the case
of a pixmap toggle, a different pixmap is used to display the
indeterminate state.
The default behavior associated with a ToggleButton in a menu depends
on the type of menu system in which it resides. By default, <Btn1>
controls the behavior of the ToggleButton. In addition, <Btn3>
controls the behavior of the ToggleButton if it resides in a PopupMenu
system. The actual mouse button used is determined by its RowColumn
parent.
Label’s resource XmNmarginLeft may be increased to accommodate the
toggle indicator when it is created.
ToggleButton uses the XmQTmenuSystem and XmQTspecifyRenderTable traits.
Classes
ToggleButton inherits behavior, resources, and traits from Core,
XmPrimitive, and XmLabel.
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 XmCR_ARM.
XmNdetailShadowThickness
Specifies the thickness of the indicator shadow. The default
thickness is 2 pixels.
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 XmCR_DISARM.
XmNfillOnSelect
Fills the indicator with the color specified in
XmNselectColor and switches the top and bottom shadow colors
when set to True. If unset, fills the indicator with the
unselect color. If indeterminate, fills the indicator with
half select color and half unselect color. Otherwise, it
switches only the top and bottom shadow colors. The default
is True only if a box type of indicator (such as a check box)
is specified, or if the XmNindicatorType is a 1-of type and a
toggle indicator is drawn.
If XmNfillOnSelect is True, XmNset is XmSET, and
XmNindicatorOn is XmINDICATOR_NONE the ToggleButton’s
background is set to XmNselectColor. For the other
XmNindicatorOn values, only the indicator is filled with
XmNselectColor.
XmNindeterminateInsensitivePixmap
Specifies the pixmap to be displayed as the button face when
the Label XmNlableType resource is XmPIXMAP, the ToggleButton
XmNset resource is XmINDETERMINATE, and the Core XmNsensitive
resource is False.
XmNindeterminatePixmap
Specifies the pixmap to be displayed as the button face when
the Label XmNlableType resource is XmPIXMAP, the ToggleButton
XmNset resource is XmINDETERMINATE, and the Core XmNsensitive
resource is True.
XmNindicatorOn
Specifies that if a toggle indicator is to be drawn, it will
be drawn to one side of the toggle text or pixmap, depending
on the XmNlayoutDirection resource of the widget. The default
value is XmINDICATOR_FILL. Toggles accept the following
values:
XmINDICATOR_NONE
No space is allocated for the indicator, and it is
not displayed. Any shadows around the entire widget
are switched when the toggle is selected or
unselected.
XmINDICATOR_BOX
The toggle indicator is in the shape of a shadowed
box.
XmINDICATOR_FILL
If the value of the XmDisplay XmNenableToggleVisual
resource is True , the visuals are those of
XmINDICATOR_CHECK_BOX ; if False , the indicator
visuals are those of XmINDICATOR_BOX.
XmINDICATOR_CHECK
The toggle indicator is in the shape of a checkmark
in the foreground color.
XmINDICATOR_CHECK_BOX
The toggle indicator is in the shape of a checkmark
enclosed in a box. This is the default if the
XmDisplay XmNenableToggleVisual resource is set.
XmINDICATOR_CROSS_BOX
The toggle indicator is in the shape of a cross
enclosed in a box.
XmINDICATOR_CROSS
The toggle indicator is in the shape of a cross.
All ToggleButton checks and crosses should be drawn in the
foreground color.
If this resource is not XmINDICATOR_NONE, it will control the
appearance of the toggle visual. If XmNset is XmINDETERMINATE
and XmNindicatorOn is not XmINDICATOR_NONE, this resource
shows a stippled flat box. If XmNset is XmINDETERMINATE,
XmNindicatorOn is XmINDICATOR_NONE, and XmNtoggleMode is
XmTOGGLE_INDETERMINATE, the label and the ToggleButton are
stippled with a combination of the XmNselectColor and the
XmNunselectColor color, and the border is flat.
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. The size of indicators inside menus may differ
from those outside of menus. Note that a change in this
resource may also cause a change in the values of the
inherited resources XmNmarginTop, XmNmarginBottom, and
XmNmarginLeft.
XmNindicatorType
Specifies if the indicator is a 1-of or N-of indicator. For
the 1-of indicator, the value can be XmONE_OF_MANY,
XmONE_OF_MANY_ROUND, or XmONE_OF_MANY_DIAMOND. For the N-of
indicator, the value is XmN_OF_MANY. This value specifies
only the visuals and does not enforce the behavior. When the
ToggleButton is in a radio box, the default is XmONE_OF_MANY;
otherwise, the default is XmN_OF_MANY. Legal values are:
XmONE_OF_MANY
When the Display XmNenableToggleVisual resource is
set, indicators are drawn with the same appearance
as XmONE_OF_MANY_ROUND; otherwise, they appear the
same as XmONE_OF_MANY_DIAMOND.
XmN_OF_MANY
The indicators are drawn as specified by the
XmNindicatorOn resource.
XmONE_OF_MANY_ROUND
A shadowed circle.
XmONE_OF_MANY_DIAMOND
A shadowed diamond.
XmNselectColor
Allows the application to specify what color fills the center
of the square, diamond-shaped, or round 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. The results of this resource depend on
the value of the Display resource XmNenableToggleColor. A
value of True causes the fill color to use the
XmHIGHLIGHT_COLOR color by default. A value of False causes
the fill color to use the background color. 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
XmINDICATOR_NONE, the value of XmNfillOnSelect must be
explicitly set to True.
This resource is also used as the background color when all
of the following conditions are met: the button is armed in a
menu, the XmNenableEtchedInMenu resource is True, the
XmNindicatorOn resource is False, and the XmNfillOnSelect
resource is True.
This resource can take the following values:
XmDEFAULT_SELECT_COLOR
Is the same as the current dynamic default, which
is a color between the background and the bottom
shadow color.
XmREVERSED_GROUND_COLORS
Forces the select color to the foreground color and
causes the default color of any text rendered over
the select color to be in the background color.
XmHIGHLIGHT_COLOR
Forces the fill color to use the highlight color.
XmNselectInsensitivePixmap
Specifies a pixmap used as the button face when the
ToggleButton is selected, the button is insensitive, and 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 when
XmNlabelType is XmPIXMAP and the ToggleButton is selected.
When the ToggleButton is unselected, the pixmap specified in
the 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 XmUNSET
indicates that the ToggleButton is not set. A value of XmSET
indicates that the ToggleButton is set. A value of
XmINDETERMINATE indicates that the ToggleButton is in an
indeterminate state (neither set nor unset). The
ToggleButton states cycle through in the order of XmSET,
XmINDETERMINATE (if XmNtoggleMode is set to
XmTOGGLE_INDETERMINATE), and XmUNSET, and then back around to
XmSET. If XmNtoggleMode is set to XmTOGGLE_BOOLEAN, then the
ToggleButton states cycle through in the order of XmSET, then
XmUNSET, and then back around to XmSET. 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).
XmNtoggleMode
Specifies the mode of the ToggleButton as either
XmTOGGLE_BOOLEAN or XmTOGGLE_INDETERMINATE. The
XmTOGGLE_INDETERMINATE value allows the XmNset resource to be
able to accept the values XmINDETERMINATE, XmSET, and
XmUNSET. The XmNtoggleMode resource is forced to
XmTOGGLE_BOOLEAN if the toggle is in an XmRowColumn widget
whose radio behavior is XmONE_OF_MANY. In XmTOGGLE_BOOLEAN
mode, the XmNset resource can only accept XmSET and XmUNSET.
XmNunselectColor
Allows the application to specify what color fills the center
of the square, diamond-shaped, or round indicator when it is
not 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 XmNbackground. For a monochrome display, the
default is set to the background color. To set the background
of the button to XmNunselectColor when XmNindicatorOn is
XmINDICATOR_NONE, the value of XmNfillOnSelect must be
explicitly set to True. This resource acts like the
XmNselectColor resource, but for the case when XmNset is
XmUNSET.
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
XmCR_VALUE_CHANGED.
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 superclasses
described in the following tables. For a complete description of each

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 state, either XmSET (selected),
XmUNSET (unselected), or XmINDETERMINATE (neither). Note
that the reported state is the state that the ToggleButton is
in after the event has been processed. For example, suppose
that a user clicks on a ToggleButton to change it from the
unselected state to the selected state. In this case,
ToggleButton changes the value of set from XmUNSET to XmSET
prior to calling the callback.
Translations
XmToggleButton includes translations from Primitive. Additional
XmToggleButton translations for buttons not in a menu system are
described in the following list.
Note that altering translations in #override or #augment mode is
undefined.
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 format, please refer to the X Toolkit
Instrinsics Documentation.

Action Routines
The XmToggleButton action routines are
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. This action 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. This action calls the
XmNarmCallback callbacks.
ArmAndActivate():
If the ToggleButton was previously set, unsets it; if the
ToggleButton was previously unset, sets it.
In a menu, this action unposts all menus in the menu
hierarchy. Unless the button is already armed, it calls the
XmNarmCallback callbacks. This action 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. This action
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. This action 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.
ButtonTakeFocus():
Causes the ToggleButton to take keyboard focus when
Ctrl<Btn1Down> is pressed, without activating the widget.
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 when
BTransfer is pressed. This action sets the XmNconvertProc of
the DragContext to a function that calls the
XmNconvertCallback procedures, possibly multiple times, for
the _MOTIF_DROP selection. 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. This action calls the
XmNvalueChangedCallback callbacks.
Additional Behavior
This widget has the following additional behavior:
<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.
