TextBox does not trigger KeyPress event with gtk3

[Bruce Steers <bsteers4@xxxxxxxxx>]

The following code...

Public Sub TextBox1_KeyPress()

  Debug Key.Text
  If Key.Text Not Like "[0-9]" Then Stop Event

End

With qt5 if i press text keys the key is printed in the debugger and the
textbox inputs nothing,
and if i press numerical keys they are printed and entered into textbox, as
expected.

gtk3 on the other hand does not fire the TextBox_Keypress event at all.
all keys are entered into the textbox and the debugger prints nothing.

So the statement on the wiki,,
https://gambaswiki.org/wiki/comp/gb.qt4/control/.keypress
Event Cancellation If you stop the event with STOP EVENT
<https://gambaswiki.org/edit/lang/stopevent>, the control won't see the
keyboard event at all.

Is only actually true for qt not gtk3
