XmArrowButton --The ArrowButton widget class
Showing IRIX 6.5.30 (default release). Unchanged since IRIX 6.5.
NAME XmArrowButton --The ArrowButton widget class SYNOPSIS #include <Xm/ArrowB.h> VERSION This page documents version 1.2 of the Motif library. 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 Ar- rowButton has been pressed in. When the ArrowButton is unselected, the shadow reverts to give the appearance that the ArrowButton is released, or out. Classes ArrowButton inherits behavior and resources from 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 program- mer 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 re- maining letters (in either lowercase or uppercase, but include any under- scores 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 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 call- back is XmCR_ACTIVATE. 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 following are values for this re- source: * XmARROW_UP. * XmARROW_DOWN. * XmARROW_LEFT. * XmARROW_RIGHT. XmNdisarmCallback Specifies a list of callbacks that is called when the ArrowButton is disarmed. To disarm this widget, 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 display's multi-click time, and this resource is set to XmMULTICLICK_DISCARD, do not process the sec- ond click. If this resource is set to XmMULTICLICK_KEEP, process the event and increment click_count in the callback structure. When the button is not in a menu, the default value is XmMUL- TICLICK_KEEP. Inherited Resources ArrowButton inherits behavior and resources from the following super- classes. For a complete description of each resource, refer to the man page for that superclass.

It con- tains 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 XmN- multiClick is set to XmMULTICLICK_KEEP. Translations XmArrowButton includes translations for XmPrimitive. Additional XmArrow- Button 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() Action Routines The XmArrowButton action routines are described below: Activate(): Draws the shadow in the unselected state. If the pointer is within the ArrowButton, calls the callbacks for XmNactivateCall- back. 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 XmNdisarmCallback to be called, either immediately or at a later time. 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 widget, this action calls the help callbacks for the nearest ancestor that has them. MultiActivate(): If XmNmultiClick is XmMULTICLICK_DISCARD, this action does noth- ing. If XmNmultiClick is XmMULTICLICK_KEEP, this action does the following: In- crements click_count in the callback structure. Draws the shadow in the unselected state. If the pointer is within the ArrowButton, calls the callbacks for XmNactivateCallback. Calls the callbacks for XmNdisarmCall- back. MultiArm(): If XmNmultiClick is XmMULTICLICK_DISCARD, this action does noth- ing. If XmNmultiClick is XmMULTICLICK_KEEP, this action draws the shadow in the selected state and calls the callbacks for XmN- armCallback. Additional Behavior This widget has the additional behavior described below: <EnterWindow>: Draws the ArrowButton shadow in its selected state if the pointer leaves and re-enters the window while BSelect is pressed. <LeaveWindow>: Draws the ArrowButton shadow in its unselected state if the pointer leaves the window while BSelect is pressed.
