Usage
By default, PowerBuilder redraws a control after each change
to properties that affect appearance. Use SetRedraw to
turn off redrawing temporarily in order to avoid flicker and reduce
redrawing time when you are making several changes to the properties
of an object or control. If the window is not visible, SetRedraw fails.
PowerBuilder environment
Inherited from DragObject. For more details on use with PowerBuilder objects,
see SetRedraw in the PowerScript Reference.
