Well a good example is your own FTestMaskBox.class of comp/gb.form

the MaskBox test form (with QT5) does nothing if you press letter keys but
inputs a number at cursor position if you press a number key.
that i think is the expected behavior of the test code.

With GTK3 it just sends the cursor far-left and inputs nothing regardless
of pressing either text or number keys.
I think this is because the KeyPress event does not trigger with GTK but
the Change event does. so the test program does not function as expected.
