## Name

XmArrowButtonGadget(3X) — XmArrowButtonGadget--The ArrowButtonGadget widget class XmArrowButtonGadgetwidget class

## Synopsis

#include <Xm/ArrowBG.h>

## DESCRIPTION

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.

### Classes

ArrowButtonGadget inherits behavior and resources from Object, RectObj, and XmGadget classes.

The class pointer is xmArrowButtonGadgetClass.

The class name is XmArrowButtonGadget.

### New Resources

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).

Name | Class | Type | Default | Access
XmNactivateCallback | XmCCallback | XtCallbackList | NULL | C
XmNarmCallback | XmCCallback | XtCallbackList | NULL | C
XmNarrowDirection | XmCArrowDirection | unsigned char | XmARROW_UP | CSG
XmNdisarmCallback | XmCCallback | XtCallbackList | NULL | C
XmNmultiClick | XmCMultiClick | unsigned char | dynamic | CSG

XmNactivateCallback |  | Specifies a list of callbacks that is called when the ArrowButtonGadget is activated. To activate the button, press and release BSelect while the pointer is inside the ArrowButtonGadget. Activating the ArrowButtonGadget also disarms it. The reason sent by this callback is XmCR_ACTIVATE.
XmNarmCallback |  | Specifies a list of callbacks that is called when the ArrowButtonGadget is armed. To arm this widget, press BSelect while the pointer is inside the ArrowButtonGadget. The reason sent by this callback is XmCR_ARM.
XmNarrowDirection |  | Sets the arrow direction. The values for this resource are: XmARROW_UP. XmARROW_DOWN. XmARROW_LEFT. XmARROW_RIGHT.
XmNdisarmCallback |  | Specifies a list of callbacks that is called when the ArrowButtonGadget is disarmed. To disarm this widget, press and release BSelect while the pointer is inside the ArrowButtonGadget. The reason sent by this callback is XmCR_DISARM.
XmNmultiClick |  | If a button click is followed by another button click within the time span specified by the display's multi-click time, and this resource is set to XmMULTICLICK_DISCARD, do not process the second click. If this resource is set to XmMULTICLICK_KEEP, process the event and increment `click_count` in the callback structure. When the ArrowButtonGadget is not in a menu, the default value is XmMULTICLICK_KEEP.

### Inherited Resources

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

Name | Class | Type | Default | Access
XmNbottomShadowColor | XmCBottomShadowColor | Pixel | dynamic | G
XmNhelpCallback | XmCCallback | XtCallbackList | NULL | C
XmNhighlightColor | XmCHighlightColor | Pixel | dynamic | G
XmNhighlightOnEnter | XmCHighlightOnEnter | Boolean | False | CSG
XmNhighlightThickness | XmCHighlightThickness | Dimension | 2 | CSG
XmNnavigationType | XmCNavigationType | XmNavigationType | XmNONE | CSG
XmNshadowThickness | XmCShadowThickness | Dimension | 2 | CSG
XmNtopShadowColor | XmCTopShadowColor | Pixel | dynamic | G
XmNtraversalOn | XmCTraversalOn | Boolean | True | CSG
XmNunitType | XmCUnitType | unsigned char | dynamic | CSG
XmNuserData | XmCUserData | XtPointer | NULL | CSG

Name | Class | Type | Default | Access
XmNancestorSensitive | XmCSensitive | Boolean | dynamic | G
XmNborderWidth | XmCBorderWidth | Dimension | 0 | CSG
XmNheight | XmCHeight | Dimension | dynamic | CSG
XmNsensitive | XmCSensitive | Boolean | True | CSG
XmNwidth | XmCWidth | Dimension | dynamic | CSG
XmNx | XmCPosition | Position | 0 | CSG
XmNy | XmCPosition | Position | 0 | CSG

Name | Class | Type | Default | Access
XmNdestroyCallback | XmCCallback | XtCallbackList | NULL | C

### Callback Information

A pointer to the following structure is passed to each callback:

    typedef struct

    {
      int  reason;

      XEvent  * event;

      int  click_count;

    } XmArrowButtonCallbackStruct;

`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 XmMULTICLICK_KEEP, otherwise it contains 1. The activate callback is invoked for each click if XmNmultiClick is set to XmMULTICLICK_KEEP.

### Behavior

XmArrowButtonGadget includes behavior from XmGadget. Additional XmArrowButtonGadget behavior is described below:

BSelect Press: |  | Draws the shadow in the selected state and calls the callbacks for XmNarmCallback.
BSelect Click or BSelectRelease: |  | Draws the shadow in the unselected state. If the pointer is within the ArrowButtonGadget, calls the callbacks for XmNactivateCallback. Calls the callbacks for XmNdisarmCallback.
BSelect Press 2+: |  | 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.
BSelect Release 2+: |  | If XmNmultiClick is XmMULTICLICK_DISCARD, this action does nothing. If XmNmultiClick is XmMULTICLICK_KEEP, this action does the following: Increments `click_count` in the callback structure. Draws the shadow in the unselected state. If the pointer is within the ArrowButtonGadget, calls the callbacks for XmNactivateCallback. Calls the callbacks for XmNdisarmCallback.
KSelect: |  | 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.
KHelp: |  | Calls the callbacks for XmNhelpCallback if any exist. If there are no help callbacks for this widget, this calls the help callbacks for the nearest ancestor that has them.
<Enter>: |  | Draws the ArrowButtonGadget shadow in its selected state if the pointer leaves and re-enters the gadget while BSelect is pressed.
<Leave>: |  | Draws the ArrowButtonGadget shadow in its unselected state if the pointer leaves the gadget while BSelect is pressed.

### Virtual Bindings

The bindings for virtual keys are vendor specific. For information about bindings for virtual buttons and keys, see VirtualBindings(3X).
