XmDrawnButton(3X)XmDrawnButton(3X)NAMEXmDrawnButton — The DrawnButton widget class
SYNOPSIS
#include <Xm/DrawnB.h>
VERSION
This page documents version 1.2 of the Motif library.
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 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
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 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).

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. 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 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 call‐
back 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 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 DrawnButton so that
the shadow appears inset. This means that the bottom shadow visuals
and top shadow visuals are reversed. XmSHADOW_OUT—draws the DrawnBut‐
ton 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 Drawn‐
Button 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.

Callback Information
A pointer to the following structure is passed to each callback: type‐
def 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 XmMUL‐
TICLICK_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
XmDrawnButton translations are listed below. These translations may
not directly correspond to a translation table. BSelect Press: Arm()

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 redrawn in the
unselected state; otherwise, the shadow is redrawn according to XmN‐
shadowType. The callbacks for XmNactivateCallback and XmNdisarmCall‐
back are called. Marks the DrawnButton as unselected and calls the
callbacks for XmNdisarmCallback. Calls the callbacks for XmNhelpCall‐
back 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 noth‐
ing.
If XmNmultiClick is XmMULTICLICK_KEEP, this action does the following:
Increments click_count in the callback structure. If XmNpushButtonEn‐
abled 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 XmNmultiClick is XmMUL‐
TICLICK_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.
