XmDrawnButton(3) Library Functions Manual XmDrawnButton(3) 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 allow the application to redraw or reposition its graphics. If the DrawnButton widget has a highlight and shadow thickness, the application should not draw in that area. To avoid drawing in the highlight and shadow area, cre- ate the graphics context with a clipping rectangle for drawing in the wid- get. The clipping rectangle should take into account the size of the wid- get's highlight thickness and shadow. DrawnButton uses the XmQTmenuSystem and XmQTspecifyRenderTable traits, and holds the XmQTactivatable trait. Classes DrawnButton inherits behavior, resources, and traits from the Core, Primi- tive, 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 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 re- source by name or by class in a .Xdefaults file, remove the XmN or XmC pre- fix 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 be- tween words). The codes in the access column indicate if the given re- source can be set at creation time (C), set by using XtSetValues (S), re- trieved by using XtGetValues (G), or is not applicable (N/A). +--------------------------------------------------------------------------------------------+ | | XmDrawnButton Resource Set | | | | Name | Class | Type | Default | Access | +----------------------+----------------------+----------------+--------------------+--------+ | XmNactivateCallback | XmCCallback | XtCallbackList | NULL | C | +----------------------+----------------------+----------------+--------------------+--------+ | XmNarmCallback | XmCCallback | XtCallbackList | NULL | C | +----------------------+----------------------+----------------+--------------------+--------+ | XmNdisarmCallback | XmCCallback | XtCallbackList | NULL | C | +----------------------+----------------------+----------------+--------------------+--------+ | XmNexposeCallback | XmCCallback | XtCallbackList | NULL | C | +----------------------+----------------------+----------------+--------------------+--------+ | XmNmultiClick | XmCMultiClick | unsigned char | dynamic | CSG | +----------------------+----------------------+----------------+--------------------+--------+ | XmNpushButtonEnabled | XmCPushButtonEnabled | Boolean | False | CSG | +----------------------+----------------------+----------------+--------------------+--------+ | XmNresizeCallback | XmCCallback | XtCallbackList | NULL | C | +----------------------+----------------------+----------------+--------------------+--------+ | XmNshadowType | XmCShadowType | unsigned char | XmSHADOW_ETCHED_IN | CSG | +----------------------+----------------------+----------------+--------------------+--------+ +----------------------+----------------------+----------------+--------------------+--------+ XmNactivateCallback Specifies the list of callbacks that is called when the widget becomes selected. The reason sent by the callback is XmCR_ACTI- VATE. This callback uses the XmQTactivatable trait. XmNarmCallback Specifies the list of callbacks that is called when the widget becomes armed. The reason sent by the callback is XmCR_ARM. XmNdisarmCallback Specifies the list of callbacks that is called when the widget becomes disarmed. The reason sent by the callback is XmCR_DIS- ARM. XmNexposeCallback Specifies the list of callbacks that is called when the widget receives an exposure event. The reason sent by the callback is XmCR_EXPOSE. 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 button is not in a menu, the default value is XmMULTICLICK_KEEP. XmNpushButtonEnabled Enables or disables the 3-dimensional shadow drawing as in Push- Button. XmNresizeCallback 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. XmNshadowType Describes the drawing style for the DrawnButton. This resource can have the following values: XmSHADOW_IN Draws the DrawnButton so that the shadow appears inset. This means that the bottom shadow visuals and top shadow visuals are reversed. XmSHADOW_OUT Draws the DrawnButton so that the shadow appears out- set. XmSHADOW_ETCHED_IN Draws the DrawnButton using a double line. This gives the effect of a line etched into the window. The thick- ness of the double line is equal to the value of XmN- shadowThickness. 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 superclasses described in the following tables.

typedef struct { int reason; XEvent * event; Window window; int click_count; } XmDrawnButtonCallbackStruct; reason Indicates why the callback was invoked. event Points to the XEvent that triggered the callback. This is NULL for XmNresizeCallback. window Is set to the window ID in which the event occurred. click_count 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. Translations XmDrawnButton includes translations from Primitive. Additional XmDrawnBut- ton translations are described in the following list. 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. 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 XmDrawnButton action routines are Activate(): If XmNpushButtonEnabled is True, redraws the shadow in the unse- lected state; otherwise, redraws the shadow according to XmNshad- owType. If the pointer is within the DrawnButton, calls the XmN- activateCallback callbacks. Arm(): If XmNpushButtonEnabled is True, redraws the shadow in the se- lected state; otherwise, redraws the shadow according to XmNshad- owType. Calls the callbacks for XmNarmCallback. ArmAndActivate(): If XmNpushButtonEnabled is True, redraws the shadow in the se- lected state; otherwise, redraws the shadow according to XmNshad- owType. Calls the callbacks for XmNarmCallback. If XmNpushButtonEnabled is True, the shadow is redrawn in the un- selected state; otherwise, the shadow is redrawn according to XmNshadowType. The callbacks for XmNactivateCallback and XmNdis- armCallback are called. These actions happen either immediately or at a later time. ButtonTakeFocus(): Causes the PushButton to take keyboard focus when Ctrl<Btn1Down> is pressed, without activating the widget. Disarm(): Marks the DrawnButton as unselected 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 increments click_count in the callback structure. If XmNpushButtonEnabled is True, this action redraws the shadow in the unselected state; otherwise, it redraws the shadow according to XmNshadowType. If the pointer is within the DrawnButton, this action calls the XmN- activateCallback callbacks and calls the callbacks for XmNdisarm- Callback. MultiArm(): If XmNmultiClick is XmMULTICLICK_DISCARD, this action does noth- ing. If XmNmultiClick is XmMULTICLICK_KEEP and if XmNpushButtonEnabled is True, this action redraws the shadow in the selected state; otherwise, it redraws the shadow according to XmNshadowType and calls the callbacks for XmNarmCallback. Additional Behavior This widget has the following additional behavior: <EnterWindow>: Draws the shadow in its selected state if XmNpushButtonEnabled is True and if the cursor leaves and re-enters the window while BSe- lect is pressed. <LeaveWindow>: Draws the shadow in its unselected state if XmNpushButtonEnabled is True and if the cursor leaves the window while BSelect is pressed.
