Hi,

thanks for all the suggestions to solve my problem with mouse
and widgets. What finally solved the problem was the following:

* use wtaddhandler to handle events in my 'drawarea':

status=wtaddhandler(drawarea,ButtonPressMask,'mousecoord')

with ButtonPressMark the call back procedure 'mousecoord'
is called when a button on the mouse is pressed.

* in the callback procedure mousecoord I use the routine wtpointer
with GetLocation:

status=wtpointer('GetLocation',draw,mouseinfo)

mouseinfo is an array containing information on the mouse,
mouseinfo(4) and mouseinfo(5) contain the x and y coordinates
in device coordinates.
