[Gambas-user] There are errors in the class "Key", and in the events KeyPress / KeyRelease?

Key.Text is not guaranteed to be set during a KeyRelease.

Please specify, I didn't notice any problem about that.

I think you meant gb.gtk instead.

Yep, this is a bug I fixed in revision #2891. I'm almost sure that it worked 
before, so maybe a recent change in GTK+ made my code fail.

Please specify, I didn't notice any problem about that.

No, it is raised, but Key.Code was zero.

As I said before, I didn't notice that. So if you can tell me how to reproduce 
it, it would be a great thing.

It is actually not lost, it is just that it should be set only during a 
KeyPress event. gb.gtk is just more clever there.
