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, create the graphics context with a clipping rectangle for drawing in the widget. The clipping rectangle should take into
account 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 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).

Specifies the list of callbacks that is called when the widget becomes selected. The reason sent by the callback is XmCR_ACTIVATE.
Specifies the list of callbacks that is called when the widget becomes armed. The reason sent by the callback is XmCR_ARM. Speci-
fies the list of callbacks that is called when the widget becomes disarmed. The reason sent by the callback is XmCR_DISARM. Speci-
fies 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 display's multi-click
time, and this resource is set to XmMULTICLICK_DISCARD, do not process the second click. If this resource is set to XmMUL-
TICLICK_KEEP, process the event and increment 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 PushButton. Specifies the list of call-
backs 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 DrawnButton so that the shadow appears inset. This means that the bottom shadow visuals and top shadow visu-
als are reversed. XmSHADOW_OUT--draws the DrawnButton so that the shadow appears outset. XmSHADOW_ETCHED_IN--draws the DrawnButton
using a double line. This gives the effect of a line etched into the window. 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 com-
ing 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 superclasses. For a complete description of each resource, refer to the man
page for that superclass.

Callback Information
A pointer to the following structure is passed to each callback: typedef struct {
int reason;
XEvent * event;
Window window;
int click_count; }XmDrawnButtonCallbackStruct;

Indicates why the callback was invoked. 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 callback is invoked for each click if XmNmultiClick is set to XmMUL-
TICLICK_KEEP.

Translations
XmDrawnButton includes translations from Primitive. Additional XmDrawnButton 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 XmDrawnButton action routines are described below: If XmNpushButtonEnabled 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
according 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 redrawn
in the unselected state; otherwise, the shadow is redrawn according to XmNshadowType. The callbacks for XmNactivateCallback and
XmNdisarmCallback are called. Marks the DrawnButton as unselected and calls the callbacks for XmNdisarmCallback. Calls the call-
backs 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. If XmNmultiClick is XmMULTICLICK_DISCARD, this action does nothing.

If XmNmultiClick is XmMULTICLICK_KEEP, this action does the following: Increments click_count in the callback structure. If XmNpush-
ButtonEnabled 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 XmNactivateCallback callbacks. Calls the callbacks for XmNdisarmCallback. If XmNmul-
tiClick is XmMULTICLICK_DISCARD, this action does nothing.

If XmNmultiClick is XmMULTICLICK_KEEP, this action does the following: 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.

Virtual Bindings
The bindings for virtual keys are vendor specific. For information about bindings for virtual buttons and keys, see VirtualBindings(3X).
