OnPreShow(Arg)

This event occurs before displaying a Screen. The Arg parameter receives the content of the Arg parameter of the OpenScreen or ShowScreen methods, which generate this event. After that, the OnShow event is generated. The next script contains an example of using this event.

Sub Screen1_OnPreShow(Arg)
  ' Screen1's title to display
  ' was passed as a parameter when using the OpenScreen
  ' method that generated this event.
  Caption = Arg
End Sub
