--- name: "XmArrowButtonGadget" section: "3" platform: "linux" package: "openmotif" version: "2.3.8-4" release: "Arch Linux 2026-11-01" platforms: ["linux"] url: "https://new.carta.tech/XmArrowButtonGadget" --- # XmArrowButtonGadget(3) The ArrowButtonGadget widget class ## NAME **XmArrowButtonGadget** — The ArrowButtonGadget widget class ## SYNOPSIS ``` #include ``` ## 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. ArrowButtonGadget holds the **XmQTactivatable** trait. ### Classes ArrowButtonGadget inherits behavior, resources, and traits from the **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). | | | | | | | | --- | --- | --- | --- | --- | --- | | **XmArrowButtonGadget Resource Set** | | **Name** | **Class** | **Type** | **Default** | **Access** | | | | | | | | | XmNactivateCallback | XmCCallback | XtCallbackList | NULL | C | | | | | | | | | XmNarmCallback | XmCCallback | XtCallbackList | NULL | C | | | | | | | | | XmNarrowDirection | XmCArrowDirection | unsigned char | XmARROW\_UP | CSG | | | | | | | | | XmNdetailShadowThickness | XmCDetailShadowThickness | Dimension | 2 | 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**. This callback uses the **XmQTactivatable** trait. - **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** - **XmNdetailShadowThickness** Specifies the thickness of the inside arrow shadows. The default thickness is 2 pixels. - **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 multiclick time and this resource is set to **XmMULTICLICK\_DISCARD**, the second click is not processed. If this resource is set to **XmMULTICLICK\_KEEP**, the event is processed and *click\_count* is incremented in the callback structure. When the ArrowButtonGadget is not in a menu, the default value is **XmMULTICLICK\_KEEP**. ### Inherited Resources **XmArrowButtonGadget** inherits behavior and resources from the superclasses described in the following tables. For a complete description of each resource, refer to the reference page for that superclass. | | | | | | | | --- | --- | --- | --- | --- | --- | | **XmGadget Resource Set** | | **Name** | **Class** | **Type** | **Default** | **Access** | | | | | | | | | XmNbackground | XmCBackground | Pixel | dynamic | CSG | | | | | | | | | XmNbackgroundPixmap | XmCPixmap | Pixmap | XmUNSPECIFIED\_PIXMAP | CSG | | | | | | | | | XmNbottomShadowColor | XmCBottomShadowColor | Pixel | dynamic | CSG | | | | | | | | | XmNbottomShadowPixmap | XmCBottomShadowPixmap | Pixmap | dynamic | CSG | | | | | | | | | XmNhelpCallback | XmCCallback | XtCallbackList | NULL | C | | | | | | | | | XmNforeground | XmCForeground | Pixel | dynamic | CSG | | | | | | | | | XmNhighlightColor | XmCHighlightColor | Pixel | dynamic | CSG | | | | | | | | | XmNhighlightOnEnter | XmCHighlightOnEnter | Boolean | False | CSG | | | | | | | | | XmNhighlightPixmap | XmCHighlightPixmap | Pixmap | dynamic | CSG | | | | | | | | | XmNhighlightThickness | XmCHighlightThickness | Dimension | 2 | CSG | | | | | | | | | XmNlayoutDirection | XmNCLayoutDirection | XmDirection | dynamic | CG | | | | | | | | | XmNnavigationType | XmCNavigationType | XmNavigationType | XmNONE | CSG | | | | | | | | | XmNshadowThickness | XmCShadowThickness | Dimension | 2 | CSG | | | | | | | | | XmNtopShadowColor | XmCTopShadowColor | Pixel | dynamic | CSG | | | | | | | | | XmNtopShadowPixmap | XmCTopShadowPixmap | Pixmap | dynamic | CSG | | | | | | | | | XmNtraversalOn | XmCTraversalOn | Boolean | True | CSG | | | | | | | | | XmNunitType | XmCUnitType | unsigned char | dynamic | CSG | | | | | | | | | XmNuserData | XmCUserData | XtPointer | NULL | CSG | | | | | | | | | | | | | | | | --- | --- | --- | --- | --- | --- | | **RectObj Resource Set** | | **Name** | **Class** | **Type** | **Default** | **Access** | | | | | | | | | XmNancestorSensitive | XmCSensitive | Boolean | dynamic | G | | | | | | | | | XmNborderWidth | XmCBorderWidth | Dimension | 0 | N/A | | | | | | | | | 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 | | | | | | | | | | | | | | | | --- | --- | --- | --- | --- | --- | | **Object Resource Set** | | **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**. The following list describes additional XmArrowButtonGadget behavior: - **\**: Draws the shadow in the selected state and calls the callbacks for **XmNarmCallback**. - **\ or \**: Draws the shadow in the unselected state. If the pointer is within the ArrowButtonGadget, calls the callbacks for **XmNactivateCallback**. Calls the callbacks for **XmNdisarmCallback**. - **\(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**. - **\(2+)**: 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 unselected state. If the pointer is within the ArrowButtonGadget, this action calls the callbacks for **XmNactivateCallback** and **XmNdisarmCallback**. - **\\**: 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. - **\\**: 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. - **\**: Draws the ArrowButtonGadget shadow in its selected state if the pointer leaves and re-enters the gadget while \ is pressed. - **\**: Draws the ArrowButtonGadget shadow in its unselected state if the pointer leaves the gadget while \ is pressed. ### Virtual Bindings The bindings for virtual keys are vendor specific.
