NAMEXmPushButton — The PushButton widget class
SYNOPSIS
#include <Xm/PushB.h>
DESCRIPTION
PushButton issues commands within an application. It consists of a
text label or pixmap surrounded by a border shadow. When a PushButton
is selected, the shadow changes to give the appearance that it has been
pressed in. When a PushButton is unselected, the shadow changes to give
the appearance that it is out.
The default behavior associated with a PushButton in a menu depends on
the type of menu system in which it resides. By default, <Btn1> con‐
trols the behavior of the PushButton. In addition, <Btn3> controls the
behavior of the PushButton if it resides in a PopupMenu system. The
actual mouse button used is determined by its RowColumn parent.
Thickness for a second shadow, used when the PushButton is the default
button, may be specified with the XmNshowAsDefault resource. If it has
a nonzero value, the Label's resources XmNmarginLeft, XmNmarginRight,
XmNmarginTop, and XmNmarginBottom may be modified to accommodate the
second shadow.
If an initial value is specified for XmNarmPixmap but not for XmNla‐
belPixmap, the XmNarmPixmap value is used for XmNlabelPixmap.
PushButton uses the XmQTmenuSystem and XmQTspecifyRenderTable traits,
and holds the XmQactivatable, XmQTmenuSavvy, and XmQTtakesDefault
traits.
Classes
PushButton inherits behavior, resources, and traits from Core, XmPrimi‐
tive, and XmLabel.
The class pointer is xmPushButtonWidgetClass.
The class name is XmPushButton.
New Resources
The following table defines a set of widget resources used by the pro‐
grammer to specify data. The programmer can also set the resource val‐
ues 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).

XmNactivateCallback
Specifies the list of callbacks that is called when PushBut‐
ton is activated. PushButton is activated when the user
presses and releases the active mouse button while the
pointer is inside that widget. Activating the PushButton also
disarms it. For this callback, the reason is XmCR_ACTIVATE.
This callback uses the XmQTactivatable trait.
XmNarmCallback
Specifies the list of callbacks that is called when PushBut‐
ton is armed. PushButton is armed when the user presses the
active mouse button while the pointer is inside that widget.
For this callback, the reason is XmCR_ARM.
XmNarmColor
Specifies the color with which to fill the armed button.
XmNfillOnArm must be set to True for this resource to have an
effect. The 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, and any
text in the label appears in the background color when the
button is armed.
This resource is also used when the button is armed in a menu
and the XmNenableEtchedInMenu resource is True.
XmNarmPixmap
Specifies the pixmap to be used as the button face if XmNla‐
belType is XmPIXMAP or XmPIXMAP_AND_STRING and PushButton is
armed. This resource is disabled when the PushButton is in a
menu.
XmNdefaultButtonShadowThickness
This resource specifies the width of the default button indi‐
cator shadow. If this resource is 0 (zero), the width of the
shadow comes from the value of the XmNshowAsDefault resource.
If this resource is greater than 0, the XmNshowAsDefault
resource is only used to specify whether this button is the
default. The default value is the initial value of XmN‐
showAsDefault.
XmNdisarmCallback
Specifies the list of callbacks that is called when PushBut‐
ton is disarmed. PushButton is disarmed when the user presses
and releases the active mouse button while the pointer is
inside that widget. For this callback, the reason is
XmCR_DISARM.
XmNfillOnArm
Forces the PushButton to fill the background of the button
with the color specified by XmNarmColor when the button is
armed and when this resource is set to True. If False, only
the top and bottom shadow colors are switched. When the
PushButton is in a menu, this resource is ignored and assumed
to be False.
XmNmultiClick
If a button click is followed by another button click within
the time span specified by the display's multiclick time, and
this resource is set to XmMULTICLICK_DISCARD, do not process
the second click. If this resource is set to XmMUL‐
TICLICK_KEEP, process the event and increment click_count in
the callback structure. When the button is in a menu, the
default is XmMULTICLICK_DISCARD; otherwise, for a button not
in a menu, XmMULTICLICK_KEEP is the default value.
XmNshowAsDefault
If XmNdefaultButtonShadowThickness is greater than 0 (zero),
a value greater than 0 in this resource specifies to mark
this button as the default button. If XmNdefaultButtonShad‐
owThickness is 0, a value greater than 0 in this resource
specifies to mark this button as the default button with the
shadow thickness specified by this resource. When the Dis‐
play resource XmNdefaultButtonEmphasis has a value of XmEX‐
TERNAL_HIGHLIGHT (the default), PushButton draws the location
cursor outside of the outer shadow. When this resource has a
value of XmINTERNAL_HIGHLIGHT, the highlight is drawn between
the inner and outer shadows. The space between the shadow
and the default shadow is equal to the sum of both shadows.
The default value is 0. When this value is not 0, the Label
resources XmNmarginLeft, XmNmarginRight, XmNmarginTop, and
XmNmarginBottom may be modified to accommodate the second
shadow. This resource is disabled when the PushButton is in
a menu.
Inherited Resources
PushButton inherits behavior and resources from the superclasses
described the following tables. For a complete description of each
resource, refer to the reference page for that superclass.

Callback Information
A pointer to the following structure is passed to each callback:
typedef struct
{
int reason;
XEvent * event;
int click_count;
} XmPushButtonCallbackStruct;
reason Indicates why the callback was invoked.
event Points to the XEvent that triggered the callback.
click_count
This value is valid only when the reason is XmCR_ACTIVATE.
It contains the number of clicks in the last multiclick
sequence if the XmNmultiClick resource is set to XmMUL‐
TICLICK_KEEP, otherwise it contains 1. The activate callback
is invoked for each click if XmNmultiClick is set to XmMUL‐
TICLICK_KEEP.
Translations
XmPushButton includes translations from Primitive.
Note that altering translations in #override or #augment mode is unde‐
fined.
Additional XmPushButton translations for XmPushButtons not in a menu
system are described in the following list.
The following key names are listed in the X standard key event transla‐
tion 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 descrip‐
tion of the format, please refer to the X Toolkit Instrinsics Documen‐
tation.

Action Routines
The XmPushButton action routines are
Activate():
This action draws the shadow in the unarmed state. If the
button is not in a menu and if XmNfillOnArm is set to True,
the background color reverts to the unarmed color. If XmNla‐
belType is XmPIXMAP or XmPIXMAP_AND_STRING, XmNlabelPixmap is
used for the button face. If the pointer is still within the
button, this action calls the callbacks for XmNactivateCall‐
back.
Arm(): This action arms the PushButton. It draws the shadow in the
armed state. If the button is not in a menu and if XmNfil‐
lOnArm is set to True, it fills the button with the color
specified by XmNarmColor. If XmNlabelType is XmPIXMAP or
XmPIXMAP_AND_STRING, the XmNarmPixmap is used for the button
face. It calls the XmNarmCallback callbacks.
ArmAndActivate():
In a menu, unposts all menus in the menu hierarchy and,
unless the button is already armed, calls the XmNarmCallback
callbacks. This action calls the XmNactivateCallback and
XmNdisarmCallback callbacks.
Outside a menu, draws the shadow in the armed state and, if
XmNfillOnArm is set to True, fills the button with the color
specified by XmNarmColor. If XmNlabelType is XmPIXMAP or
XmPIXMAP_AND_STRING, XmNarmPixmap is used for the button
face. This action calls the XmNarmCallback callbacks.
Outside a menu, this action also arranges for the following
to happen, either immediately or at a later time: the shadow
is drawn in the unarmed state and, if XmNfillOnArm is set to
True, the background color reverts to the unarmed color. If
XmNlabelType is XmPIXMAP or XmPIXMAP_AND_STRING, XmNla‐
belPixmap is used for the button face. The XmNactivateCall‐
back and XmNdisarmCallback callbacks are called.
BtnDown():
This action unposts any menus posted by the PushButton's par‐
ent 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 and acti‐
vates the PushButton. It calls the XmNactivateCallback call‐
backs and then the XmNdisarmCallback callbacks.
ButtonTakeFocus():
Causes the PushButton 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, when the shell's keyboard focus policy is
XmEXPLICIT, restores keyboard focus to the widget that had
the focus before the menu system was entered. This action
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 top-level Pulldown MenuPane from a MenuBar, unposts the
menu, disarms the MenuBar CascadeButton and the MenuBar; and,
when the shell's keyboard focus policy is XmEXPLICIT,
restores keyboard focus to the widget that had the focus
before the MenuBar was entered. In other Pulldown MenuPanes,
it unposts the menu.
In a Popup MenuPane, this action unposts the menu and
restores keyboard focus to the widget from which the menu was
posted.
MultiActivate():
If XmNmultiClick is XmMULTICLICK_DISCARD, this action does
nothing.
If XmNmultiClick is XmMULTICLICK_KEEP, this action increments
click_count in the callback structure and draws the shadow in
the unarmed state. If the button is not in a menu and if
XmNfillOnArm is set to True, the background color reverts to
the unarmed color. If XmNlabelType is XmPIXMAP, the XmNla‐
belPixmap is used for the button face. If the pointer is
within the PushButton, calls the callbacks for XmNactivate‐
Callback and XmNdisarmCallback.
MultiArm():
If XmNmultiClick is XmMULTICLICK_DISCARD, this action does
nothing.
If XmNmultiClick is XmMULTICLICK_KEEP, this action draws the
shadow in the armed state. If the button is not in a menu
and if XmNfillOnArm is set to True, this action fills the
button with the color specified by XmNarmColor. If XmNlabel‐
Type is XmPIXMAP, the XmNarmPixmap is used for the button
face. This action calls the XmNarmCallback callbacks.
ProcessDrag():
Drags the contents of a PushButton label, identified when
BTransfer is pressed. This action sets the XmNconvertProc of
the DragContext to a function that calls the XmNconvertCall‐
back procedures, possibly multiple times, for the _MOTIF_DROP
selection. This action is undefined for PushButtons used in
a menu system.
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 PushButton is not in a menu and the cursor leaves and
then reenters the PushButton's window while the button is
pressed, this action draws the shadow in the armed state. If
XmNfillOnArm is set to True, it also fills the button with
the color specified by XmNarmColor. If XmNlabelType is
XmPIXMAP or XmPIXMAP_AND_STRING, XmNarmPixmap is used for the
button face.
<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 PushButton is not in a menu and the cursor leaves the
PushButton's window while the button is pressed, this action
draws the shadow in the unarmed state. If XmNfillOnArm is
set to True, the background color reverts to the unarmed
color. If XmNlabelType is XmPIXMAP or XmPIXMAP_AND_STRING,
the XmNlabelPixmap is used for the button face.
