Fires when a widget appears.
(self)
Arguments[]
- self
- Frame - The appearing widget.
Description[]
- The OnShow event is called when a hidden frame is about to become visible on screen.
- Normally requires the frame to have previously been hidden; i.e. repeated calls to Region:Show() are ignored.
- However, if a frame is defined in XML then OnShow also fires after OnLoad unless hidden at the time.
