Good hint! I run under kde environment. With a gnome desktop it works as expected :-) But is there a way to 
fix this problem so that the program runs under other desktops/wm also? I run on a fedora 21 with quite new 
gnome and kde installed. It is no problem to switch there between gnome and kde but other users have maybe 
only kde or some other desktop/wm. Any idea how to dig in the details of that problem?

Sorry for that! The source I send was the result of a long code shrink from my bigger application. So I did a 
lot of test code simplifications and modifications. So I "spend" some german expressions under a bit of time 
pressure there :-)

Thanks for that hint! How can I replace that? Which is the new "modern" way to use default buttons?
In general: Is there a page of changes and deprecated functions and recommendations for the replacement?

Thanks
