[Gambas-user] First look at Gambas 3

[Michael]

Benoit,
Here is an important piece of additional information. If I change my 
project components from gb.qt4 to gb.gtk then the error #11 disappears.
Also my desktop height is correctly reported as 1050 when using GTK. 
Also the font of a GTK frame does not automatically go bold. I was using 
QT in Gambas 2 for it's printer and draw library but I can switch to GTK 
in Gambas3 as soon as I work out how to use the new print facilities.
Regards
Michael
