> How do I change the cursor of a Command (or other) Widget?

In order to allow the user to override your choice of cursor, specify
the cursor in an application defaults file.  For example, to set all
command widgets in the application class of Demo to use the gumby cursor,
put this in your app defaults file:

Demo*Command.cursor:	gumby

If you want to set the cursor in your code, you will insure that the
particular cursor you chose can never be changed by a user.
For an individual widget, such as a Command widget, 
the cursor can be set at creation time or later, using the resource
XtNcursor.  Here's some excerpted code as an example:

#include <X11/cursorfont.h>

	cursor = XCreateFontCursor(XtDisplay(widget), XC_gumby);
	XtSetArg(args[0], XtNcursor, cursor);
	XtCreateManagedWidget("button", commandWidgetClass, parent, args, ONE);
	
or, after the widget has been realized ...
	cursor = XCreateFontCursor(XtDisplay(widget), XC_gumby);
	XtSetArg(args[0], XtNcursor, cursor);
	XtSetValues(button, args, ONE);

In case you want to set the cursor of a popup window, use the Xlib
function XDefineCursor after the popup has been realized.


> WidgetSet (w, XtNcursor, cursor, ...) doesn't seem to work.

I don't know where this interface is defined, or what it is.
