NAME
XmArrowButton -- The ArrowButton widget class
SYNOPSIS
#include <Xm/ArrowB.h>
DESCRIPTION
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 holds the XmQTactivatable trait. Classes ArrowButton inherits behavior, resources, and traits from the Core and XmPrimitive classes. The class pointer is xmArrowButtonWidgetClass. The class name is XmArrowButton. 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). +-------------------------------------------------------------------------------------------+ | | XmArrowButton 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 ArrowButton is activated. To activate the button, press and release BSelect while the pointer is inside the ArrowButton widget. Activating the ArrowButton 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 ArrowButton is armed. To arm this widget, press BSelect while the pointer is inside the ArrowButton. The reason sent by this callback is XmCR_ARM. XmNarrowDirection Sets the arrow direction. The values for this resource are o XmARROW_UP o XmARROW_DOWN o XmARROW_LEFT o 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 ArrowButton is disarmed. To disarm this wid- get, press and release BSelect while the pointer is inside the ArrowButton. The reason for this callback is XmCR_DISARM. XmNmultiClick If a button click is followed by another button click within the time span specified by the dis- play'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 button is not in a menu, the default value is XmMULTICLICK_KEEP. Inherited Resources ArrowButton inherits behavior and resources from the superclasses described in the following table. For a complete description of each resource, refer to the reference page for that superclass. +---------------------------------------------------------------------------------------------------+ | |

+------------------------------+-------------------------------+----------------+----------------------+--------+ 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 XmMUL- TICLICK_KEEP. Translations XmArrowButton includes translations for XmPrimitive. The following key names are listed in the X standard key event translation table syntax. This format is the one used by Motif to specify the widget actions corre- sponding to a given key. A brief overview of the format is provided under VirtualBindings(3). For a complete description of the format, please refer to the X Toolkit Instrinsics Documentation. <EnterWindow>: Enter() <LeaveWindow>: Leave() c<Btn1Down>: ButtonTakeFocus() ~c<Btn1Down>: Arm() ~c<Btn1Down>,~c<Btn1Up>: Activate() Disarm() ~c<Btn1Down>(2+): MultiArm() ~c<Btn1Up>(2+): MultiActivate() ~c<Btn1Up>: Activate() Disarm() :<Key><osfActivate>: PrimitiveParentActivate() :<Key><osfCancel>: PrimitiveParentCancel() :<Key><osfSelect>: ArmAndActivate() :<Key><osfHelp>: Help() ~s ~m ~a <Key>Return: PrimitiveParentActivate() ~s ~m ~a <Key>space: ArmAndActivate() Action Routines The XmArrowButton action routines are Activate(): Draws the shadow in the unselected state. If the pointer is within the ArrowButton, calls the call- backs for XmNactivateCallback. Arm(): Draws the shadow in the selected state and calls the callbacks for XmNarmCallback. ArmAndActivate(): 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 XmNdisarm- Callback to be called, either immediately or at a later time. ButtonTakeFocus(): Causes the ArrowButton to take keyboard focus when Ctrl<Btn1Down> is pressed, without activating the widget. Disarm(): Draws the shadow in the unselected state and calls the callbacks for XmNdisarmCallback. Help(): Calls the callbacks for XmNhelpCallback if any exist. If there are no help callbacks for this wid- get, this action calls the help callbacks for the nearest ancestor that has them. MultiActivate(): 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 ArrowButton, this action calls the callbacks for XmNactivateCallback and XmNdisarmCallback. MultiArm(): If XmNmultiClick is XmMULTICLICK_DISCARD, this action does nothing. If XmNmultiClick is XmMUL- TICLICK_KEEP, this action draws the shadow in the selected state and calls the callbacks for XmNarm- Callback. Additional Behavior This widget has the following additional behavior: <EnterWindow>: Draws the ArrowButton shadow in its selected state if the pointer leaves and re-enters the window while <Btn1> is pressed. <LeaveWindow>: Draws the ArrowButton shadow in its unselected state if the pointer leaves the window while <Btn1> is pressed. Virtual Bindings The bindings for virtual keys are vendor specific. For information about bindings for virtual buttons and keys, see VirtualBindings(3).
