Do default

Syntax

Do default Returns return-value

Description

This command is used within the code for a custom property, and performs the default behavior for the built-in property with the same name as a custom property. Do default sets the flag if some built-in processing for the property exists.

Note that where the return field is an item reference, the command sets the reference but does not assign to it: you must do this with Calculate or Do Itemref.$assign(value).

Example

# Adding a method called $horzscroll.$assign to a window causes this method to be executed whenever
# Do $horzscroll.$assign is called. If the window is over 20 pixels wide when the method is called the default 
# behavior for $horzscroll.$assign is performed, that is a scroll bar is added. 
# declare parameter pScrollBarOn of type Boolean 
If  pScrollBarOn&$cinst.$width<20
  # window too narrow for a scroll bar 
  Quit method 
Else
  # assign a horz scroll bar 
  Do default 
End If
