XmDrawnButton(3X) XmDrawnButton(3X) NAME XmDrawnButton - The DrawnButton widget class SYNOPSIS #include <Xm/DrawnB.h> DESCRIPTION The DrawnButton widget consists of an empty widget window surrounded by a shadow border. It provides the application developer with a graphics area that can have PushButton input semantics. Callback types are defined for widget exposure and widget resize to al- low the application to redraw or reposition its graphics. If the DrawnButton widget has a highlight and shadow thickness, the applica- tion should not draw in that area. To avoid drawing in the highlight and shadow area, create the graphics context with a clipping rectangle for drawing in the widget. The clipping rectangle should take into ac- count the size of the widget's highlight thickness and shadow. Classes DrawnButton inherits behavior and resources from Core, XmPrimitive, and XmLabel Classes. The class pointer is xmDrawnButtonWidgetClass. The class name is XmDrawnButton. New Resources The following table defines a set of widget resources used by the pro- grammer to specify data. The programmer can also set the resource val- ues 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). XmDrawnButton Resource Set Class: XmCCallback Default: NULL Type: XtCallbackList Access: C Class: XmCCallback Default: NULL Type: XtCallbackList Access: C Class: XmC- Callback Default: NULL Type: XtCallbackList Access: C Class: XmCCall- back Default: NULL Type: XtCallbackList Access: C Class: XmCMultiClick Default: dynamic Type: unsigned char Access: CSG Class: XmCPushButto- nEnabled Default: False Type: Boolean Access: CSG Class: XmCCallback Default: NULL Type: XtCallbackList Access: C Class: XmCShadowType De- fault: XmSHADOW_ETCHED_IN Type: unsigned char Access: CSG Specifies the list of callbacks that is called when the widget becomes selected. The reason sent by the callback is XmCR_ACTI- VATE. Specifies the list of callbacks that is called when the widget becomes armed. The reason sent by the callback is XmCR_ARM. Specifies the list of callbacks that is called when the widget becomes disarmed. The reason sent by the callback is XmCR_DISARM. Specifies the list of callbacks that is called when the widget receives an exposure event. The reason sent by the callback is XmCR_EXPOSE. If a button click is followed by another button click within the time span specified by the dis- play's multi-click time, and this resource is set to XmMUL- TICLICK_DISCARD, do not process the second click. If this re- source is set to XmMULTICLICK_KEEP, process the event and incre- ment click_count in the callback structure. When the button is not in a menu, the default value is XmMULTICLICK_KEEP. Enables or disables the three-dimensional shadow drawing as in PushBut- ton. Specifies the list of callbacks that is called when the widget receives a resize event. The reason sent by the callback is XmCR_RESIZE. The event returned for this callback is NULL. Describes the drawing style for the DrawnButton. This resource can have the following values: XmSHADOW_IN--draws the DrawnBut- ton so that the shadow appears inset. This means that the bot- tom shadow visuals and top shadow visuals are reversed. XmSHADOW_OUT--draws the DrawnButton so that the shadow appears outset. XmSHADOW_ETCHED_IN--draws the DrawnButton using a dou- ble line. This gives the effect of a line etched into the win- dow. The thickness of the double line is equal to the value of XmNshadowThickness. XmSHADOW_ETCHED_OUT--draws the DrawnButton using a double line. This gives the effect of a line coming out of the window. The thickness of the double line is equal to the value of XmNshadowThickness. Inherited Resources DrawnButton inherits behavior and resources from the following super- classes. For a complete description of each resource, refer to the man page for that superclass.

Points to the XEvent that triggered the callback. This is NULL for XmNresizeCallback. Is set to the window ID in which the event occurred. 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 call- back is invoked for each click if XmNmultiClick is set to XmMUL- TICLICK_KEEP. Translations XmDrawnButton includes translations from Primitive. Additional XmDrawn- Button translations are listed below. These translations may not di- rectly 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 XmDrawnButton action routines are described below: If XmNpushButto- nEnabled is True, redraws the shadow in the unselected state; other- wise, redraws the shadow according to XmNshadowType. If the pointer is within the DrawnButton, calls the XmNactivateCallback callbacks. If XmNpushButtonEnabled is True, redraws the shadow in the selected state; otherwise, redraws the shadow according to XmNshadowType. Calls the callbacks for XmNarmCallback. If XmNpushButtonEnabled is True, redraws the shadow in the selected state; otherwise, redraws the shadow accord- ing to XmNshadowType. Calls the callbacks for XmNarmCallback. Arranges for the following to happen, either immediately or at a later time: If XmNpushButtonEnabled is True, the shadow is re- drawn in the unselected state; otherwise, the shadow is redrawn according to XmNshadowType. The callbacks for XmNactivateCall- back and XmNdisarmCallback are called. Marks the DrawnButton as unselected and calls the callbacks for XmNdisarmCallback. Calls the callbacks for XmNhelpCallback if any exist. If there are no help callbacks for this widget, this action calls the help call- backs for the nearest ancestor that has them. If XmNmultiClick is XmMULTICLICK_DISCARD, this action does nothing. If XmNmultiClick is XmMULTICLICK_KEEP, this action does the fol- lowing: Increments click_count in the callback structure. If Xm- NpushButtonEnabled is True, redraws the shadow in the unselected state; otherwise, redraws the shadow according to XmNshadowType. If the pointer is within the DrawnButton, calls the XmNacti- vateCallback callbacks. Calls the callbacks for XmNdisarmCall- back. If XmNmultiClick is XmMULTICLICK_DISCARD, this action does nothing. If XmNmultiClick is XmMULTICLICK_KEEP, this action does the fol- lowing: If XmNpushButtonEnabled is True, redraws the shadow in the selected state; otherwise, redraws the shadow according to XmNshadowType. Calls the callbacks for XmNarmCallback. Additional Behavior This widget has the additional behavior described below: Draws the shadow in its selected state if XmNpushButtonEnabled is True and if the cursor leaves and re-enters the window while BSelect is pressed. Draws the shadow in its unselected state if XmNpushButtonEnabled is True and if the cursor leaves the window while BSelect is pressed.
