NAME
XmQTactivatable - A widget holding this trait will be
treated as a command button in a DialogBox or as a major tab
in a Notebook
SYNOPSIS
#include <Xm/ActivatableT.h>
typedef struct {
int version;
XmActivatableCallBackProc changeCB;
} XmActivatableTraitRec, *XmActivatableTrait;
void (*XmActivatableCallBackProc)(
Widget,
XtCallbackProc,
XtPointer,
Boolean);
VERSION
This page documents Motif 2.1.
DESCRIPTION
A widget holding the XmQTactivatable trait wishes to be
treated as a command button when its parent widget is a
DialogBox. The standard Motif DialogBox widgets
(XmMessageBox, XmSelectionBox, and XmFileSelectionBox) place
child widgets having this trait at the bottom of the
DialogBox widget, underneath the separator.
In addition, if the XmNotebook widget is the parent of a
widget having this trait, then XmNotebook sets the default
value of the XmNnotebookChildType constraint to XmMAJOR_TAB.
The following standard Motif primitive widgets and gadgets
hold this trait:
o XmPushButton
o XmDrawnButton
o XmArrowButton
o XmPushButtonGadget
o XmArrowButtonGadget
In addition, the following standard Motif manager widgets
examine their children for this trait:
o XmMessageBox
o XmSelectionBox

The changeCB Trait Method
void changeCB(
Widget widget,
XtCallbackProc activCB,
XtPointer clientData,
Boolean setunset);
The changeCB trait method is responsible for adding or
removing callback activCB from the list of callbacks. A
child widget holding this trait should provide a callback
resource that is called when the widget is activated. (This
resource is typically named XmNactivateCallback; however,
you could give this resource a different name if you
prefer.)
widget Specifies the child widget that is to have its
list of callbacks modified.
activCB Specifies the callback that is to be added or
removed from the list of callbacks.
clientData
Specifies additional data to be passed to the
callback.
setunset Specifies a Boolean value. If this value is True,
the setValuetrait method adds activCB to the list
of callbacks. If this value is False, the activCB
is removed from the list of callbacks.
