XmPushButton - The PushButton widget class
#include <Xm/PushB.h>
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, BSelect controls the behavior of the PushButton. In addition, BMenu 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 by using the XmNshowAsDefault resource. If it has a non-zero 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 XmNlabelPixmap, the XmNarmPixmap value is used for XmNlabelPixmap.
PushButton inherits behavior and resources from Core, XmPrimitive, and XmLabel Classes.
The class pointer is xmPushButtonWidgetClass.
The class name is XmPushButton.
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).

A pointer to the following structure is passed to each callback:
typedef struct { int reason; XEvent * event; int click_count; } XmPushButtonCallbackStruct;
XmPushButton includes translations from Primitive.
Note that altering translations in #override or #augment mode is undefined.
Additional XmPushButton translations for XmPushButtons not in a menu system are listed below. These translations may not directly correspond to a translation table.
BDrag Press: ProcessDrag() BSelect Press: Arm() BSelect Click: Activate() Disarm() BSelect Release: Activate() Disarm() BSelect Press 2+: MultiArm() BSelect Release 2+: MultiActivate() Disarm() KSelect: ArmAndActivate() KHelp: Help()
XmPushButton inherits menu traversal translations from XmLabel. Additional XmPushButton translations for PushButtons 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() KActivate: ArmAndActivate() KSelect: ArmAndActivate() MAny KCancel: MenuShellPopdownOne()
The XmPushButton action routines are described below:
Outside a menu, does the following: 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, the XmNarmPixmap is used for the button face. 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, the XmNlabelPixmap is used for the button face. The XmNactivateCallback and XmNdisarmCallback callbacks are called.
In a Popup MenuPane, unposts the menu and restores keyboard focus to the widget from which the menu was posted.
If XmNmultiClick is XmMULTICLICK_KEEP, this action does the following: Increments click_count in the callback structure. 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 XmNlabelPixmap is used for the button face. If the pointer is within the PushButton, calls the callbacks for XmNactivateCallback. Calls the callbacks for XmNdisarmCallback.
If XmNmultiClick is XmMULTICLICK_KEEP, this action does the following: Draws the shadow in the armed state. If the button is not in a menu and if XmNfillOnArm is set to True, fills the button with the color specified by XmNarmColor. If XmNlabelType is XmPIXMAP, the XmNarmPixmap is used for the button face. Calls the XmNarmCallback callbacks.
This widget has the additional behavior described below:
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, the XmNarmPixmap is used for the button face.
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, the XmNlabelPixmap is used for the button face.
