XmArrowButtonGadget - The ArrowButtonGadget widget class
#include <Xm/ArrowBG.h>
ArrowButtonGadget
consists of a directional arrow surrounded by a border shadow. When it is
selected, the shadow changes to give the appearance that the ArrowButtonGadget
has been pressed in. When it is unselected, the shadow reverts to give the
appearance that the button is released, or out.
ArrowButtonGadget inherits behavior and resources from Object, RectObj, and XmGadget classes.
The class pointer is xmArrowButtonGadgetClass.
The class name is XmArrowButtonGadget.
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).

ArrowButtonGadget inherits behavior and resources from the following superclasses. For a complete description of each resource, refer to the man page for that superclass.
XmGadget Resource Set
Class: XmCBottomShadowColor Default: dynamic Type: Pixel Access: G Class: XmCCallback Default: NULL Type: XtCallbackList Access: C Class: XmCHighlightColor Default: dynamic Type: Pixel Access: G Class: XmCHighlightOnEnter Default: False Type: Boolean Access: CSG Class: XmCHighlightThickness Default: 2 Type: Dimension Access: CSG Class: XmCNavigationType Default: XmNONE Type: XmNavigationType Access: CSG Class: XmCShadowThickness Default: 2 Type: Dimension Access: CSG Class: XmCTopShadowColor Default: dynamic Type: Pixel Access: G Class: XmCTraversalOn Default: True Type: Boolean Access: CSG Class: XmCUnitType Default: dynamic Type: unsigned char Access: CSG Class: XmCUserData Default: NULL Type: XtPointer Access: CSG

Object Resource Set
Class: XmCCallback Default: NULL Type: XtCallbackList Access: C
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.
XmArrowButtonGadget includes behavior from XmGadget. Additional XmArrowButtonGadget behavior is described below: Draws the shadow in the selected state and calls the callbacks for XmNarmCallback. Draws the shadow in the unselected state. If the pointer is within the ArrowButtonGadget, calls the callbacks for XmNactivateCallback. Calls the callbacks for XmNdisarmCallback. If XmNmultiClick is XmMULTICLICK_DISCARD, this action does nothing. If XmNmultiClick is XmMULTICLICK_KEEP, this action draws the shadow in the selected state and calls the callbacks for XmNarmCallback. If XmNmultiClick is XmMULTICLICK_DISCARD, this action does nothing.
The bindings for virtual keys are vendor specific. For information about
