XmArrowButton - The ArrowButton widget class
#include <Xm/ArrowB.h>
ArrowButton
consists of a directional arrow surrounded by a border shadow. When it is
selected, the shadow changes to give the appearance that the ArrowButton has
been pressed in. When the ArrowButton is unselected, the shadow reverts to
give the appearance that the ArrowButton is released, or out.
ArrowButton inherits behavior and resources from Core and XmPrimitive classes.
The class pointer is xmArrowButtonWidgetClass.
The class name is XmArrowButton.
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).

ArrowButton inherits behavior and resources from the following superclasses. For a complete description of each resource, refer to the man page for that superclass.

A pointer to the following structure is passed to each callback:
typedef struct
{
int reason;
XEvent * event;
int click_count;
} XmArrowButtonCallbackStruct;
Indicates why the callback was invoked.
Points to the XEvent that triggered the
callback.
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 XmMULTICLICK_KEEP; otherwise it contains 1. The activate callback is invoked for each click if XmNmultiClick is set to XmMULTICLICK_KEEP.
XmArrowButton includes translations for XmPrimitive. Additional XmArrowButton
translations are listed below. These translations may not directly correspond
to a translation table.
BSelect Press: Arm()
BSelect Click: Activate()
Disarm()
BSelect Release:Activate()
Disarm()
BSelect Press 2+:MultiArm()
BSelect Release 2+:MultiActivate()
KSelect: ArmAndActivate()
KHelp: Help()
The XmArrowButton action routines are described below: Draws the shadow in the unselected state. If the pointer is within the ArrowButton, calls the callbacks for XmNactivateCallback. Draws the shadow in the selected state and calls the callbacks for XmNarmCallback. Draws the shadow in the selected state and calls the callbacks for XmNarmCallback. Arranges for the shadow to be drawn in the unselected state and the callbacks for XmNactivateCallback and XmNdisarmCallback to be called, either immediately or at a later time. Draws the shadow in the unselected state and calls the callbacks for XmNdisarmCallback. 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. If XmNmultiClick is XmMULTICLICK_DISCARD, this action does nothing.
This widget has the additional behavior described below:
Draws the ArrowButton shadow in its selected state if the
pointer leaves and re-enters the window while BSelect is pressed.
Draws the ArrowButton shadow in its unselected state if the
pointer leaves the window while BSelect is pressed.
The bindings for virtual keys are vendor specific. For information about
