Hello,
At this point I am not getting any error. When I modified this program
and set the size of the MainFrame to values of the certain aspect ratio
(y size is smaller than x axis) I get segv error. I was wondering whether
this error is related to the problem I described. If I don't define
MyMainFrame as the class and define mainWin in the main program I don't
get the quoted message whatever the size of the MainFrame. I will
investigate
this with a small program.
Thank you and best regards,
Michal

Hi Michal,
what is the error you get when running this program? A segv or
something like that? I don't see that from your debugger output. For me
the program runs and terminates fine when the size if given as 200,100,
except that all buttons overlap.
Cheers, Fons.
