Hi
I don't understand widget's mechanisms!
My main procedure is named Windows and here I create and realize the
widget.
By the procedure Windows_event I can to manage the events.
But how can I pass parameters read in widget from windows_Event
procedure to window procedure?
Could you make me a simple example?
thanks
Roberto

If I understand you correctly, I think you are asking
about what I call a "dialog widget". Here is an example
of how to build such a thing:
