Yep. The problem comes from the Gambas GUi events internal design. The GridView control is a compound control written in Gambas. Consequently, it will see the keyboard events *before* the GridView user. For native controls, this is the contrary: you get its keyboard events before it handles them. I don't know if I will be able to have the same behaviour in the two cases. But I will try. :-) If you can't wait, there is a workaround: using an Observer on the GridView internal ScrollArea to catch the keyboard events before the GridView sees them. That way: MyObserver = New Observer(MyGridView.Children[0]) As "MyGridViewObserver" ... Public Sub MyGridViewObserver_KeyPress ... End Tell me if that workaround actually works.
