598.0. "Event Processing (self or parent)" by CALL::SWEENEY (Wall Street is my beat) Fri Apr 14 1989 01:14
Sorry but DECWINDOWS_PROGRAMMING is unavailable right now.
Windows are, of course, rectangles. By using a window with background
pixmap = parent relative, the drawing operations are not obvious to the
user as being clipped to that rectangle.
There is a "hot" polygon that I would like to some events in, but if
the event (button or otherwise) is outside that polygon, I'd like to
send it to the parent window.
The context is the parent window is defined by a adb-like widget
(subclass of constraint), and the window is also defined by a push
button-like widget (subclass of core). Both are being written by me.
Is the solution as simple as
if (event is in hot-polygon) process the event
else XSendEvent (XtDisplay(parent),XtWindow(parent)...
inside an action routine in the widget... or is there a better way.

| Why don't you just jam the parent's window ID into the event block and call
XtDispatch from within the child widget's event handler? You may also
have to adjust the event coordinates, but I assume you've thought about that.
