[Gambas-user] First look at Gambas 3

By having a QT and a GTK+ component that share the same interface:

1) You can write your program, and change the GUI as you like.

2) By using the gb.gui component, your program will use GTK+ on Gnome and QT 
on KDE.

Of course, as GTK+ and QT are very different, the two Gambas components cannot 
behave 100% identical, and sometimes one have a bug that the other one don't 
have. 

But I try to make them identical as much as possible, so do not hesitate to 
report when they behave differently.

Regards,
