Open, VIRTUAL
The Open method prepares the PrintPreviewClass window for initial display. It is designed to execute on window opening events such as EVENT:OpenWindow and EVENT:GainFocus.
Implementation:
The Open method sets the window's initial size and position, enables and disables controls as needed, and sets up the specified zoom configuration.
The WindowManager.TakeWindowEvent method calls the Open method.
Example:
ThisWindow.TakeWindowEvent PROCEDURE
CODE
CASE EVENT()
OF EVENT:OpenWindow
IF ~BAND(SELF.Inited,1)
SELF.Open
END
OF EVENT:GainFocus
IF BAND(SELF.Inited,1)
SELF.Reset
ELSE
SELF.Open
END
END
RETURN Level:Benign
