Another problem turned up - the examples with DrawingArea seems all to 
use gb.qt4 (tried with gb.qt5 and gb.qt5.ext too) so when I start the 
program I get the error-message /The program returns the value //1/ 
that's it. I'm not sure at all what could be the reason for that error, 
but several of the projects I installed from the Software-Farm does the 
same.
On the other hand, when I try to place only a DrawingArea and a button 
on the form and make this:

/Public Sub Button1_Click()

   Draw.Begin(da1)
   Draw.Line(15, 15, 20, 20)
   Draw.End

End
/
I get the error-message /Cannot paint outside of Draw handler
/
You see me somehow confused, am happy for any help.
