Fons,
Thanks for the quick response.
I made the change you suggested but I still get the same error message and
monitorClose() is never called. (I added an output statement to make sure I
was calling the new version of the code... the new output message appears,
but so does the old error message.)
Any other suggestions?
Cheers,
Tony

Hi Tony,
try:
rc->Connect("CloseWindow()", "DvatCanvas", this, "monitorClose()");
this way you tell the system to use the DvatCanvas::monitorClose() slot
for "this" instance of DvatCanvas.
Cheers, Fons.
