[Gambas-user] Empty ComboBox are filled while scrolling mouse without key press (gb.qt5)

[Safiur Rahman]

Stop Events works for Panel and other containers but doesn't work with
ComboBox

This works
Public Sub Panel1_MouseWheel()
 If Mouse.Delta Then Stop Event
End

This does not work
Public Sub ComboBox1_MouseWheel()
 If Mouse.Delta Then Stop Event
End

Also setting the ComboBox to ReadOnly while the mouse cursor is over it
makes no difference because you can still change text of ReadOnly ComboBox
with mouse wheel scroll.
