NAME [Toc] [Back]
XmToggleButton - The ToggleButton widget class
SYNOPSIS [Toc] [Back]
#include <Xm/ToggleB.h>
DESCRIPTION [Toc] [Back]
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 [Toc] [Back]
ToggleButton inherits behavior, resources, and traits from Core,
XmPrimitive, and XmLabel.
The class pointer is xmToggleButtonWidgetClass.
The class name is XmToggleButton.

New Resources [Toc] [Back]
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 [Toc] [Back]
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 [Toc] [Back]
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 [Toc] [Back]
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 [Toc] [Back]
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 [Toc] [Back]
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 [Toc] [Back]
The toggle indicator is in the shape of a shadowed
box.
XmINDICATOR_FILL [Toc] [Back]
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 [Toc] [Back]
The toggle indicator is in the shape of a
checkmark in the foreground color.
XmINDICATOR_CHECK_BOX [Toc] [Back]
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 [Toc] [Back]
The toggle indicator is in the shape of a cross
enclosed in a box.
XmINDICATOR_CROSS [Toc] [Back]
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
- 4 - Formatted: January 24, 2005
XmToggleButton(library call) XmToggleButton(library call)
XmNselectColor and the XmNunselectColor color, and the
border is flat.
XmNindicatorSize [Toc] [Back]
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 [Toc] [Back]
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 [Toc] [Back]
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 [Toc] [Back]
The indicators are drawn as specified by the
XmNindicatorOn resource.
XmONE_OF_MANY_ROUND [Toc] [Back]
A shadowed circle.
XmONE_OF_MANY_DIAMOND [Toc] [Back]
A shadowed diamond.
XmNselectColor [Toc] [Back]
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-pixelwide
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
- 5 - Formatted: January 24, 2005
XmToggleButton(library call) XmToggleButton(library call)
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 [Toc] [Back]
Is the same as the current dynamic default, which
is a color between the background and the bottom
shadow color.
XmREVERSED_GROUND_COLORS [Toc] [Back]
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 [Toc] [Back]
Forces the fill color to use the highlight color.
XmNselectInsensitivePixmap [Toc] [Back]
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 [Toc] [Back]
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 [Toc] [Back]
Specifies the amount of spacing between the toggle indicator
and the toggle label (text or pixmap).
XmNtoggleMode [Toc] [Back]
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 [Toc] [Back]
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 onepixel-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 [Toc] [Back]
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 [Toc] [Back]
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 [Toc] [Back]
ToggleButton inherits behavior and resources from the superclasses
described in the following tables. For a complete description of each
resource, refer to the reference page for that superclass.

Callback Information [Toc] [Back]
A pointer to the following structure is passed to each callback:
typedef struct
{
int reason;
XEvent * event;
- 11 - Formatted: January 24, 2005
XmToggleButton(library call) XmToggleButton(library call)
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 [Toc] [Back]
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

Action Routines [Toc] [Back]
The XmToggleButton action routines are
- 13 - Formatted: January 24, 2005
XmToggleButton(library call) XmToggleButton(library call)
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 [Toc] [Back]
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.
