TakeWindowEvent, DERIVED, PROC
The TakeWindowEvent method processes all non-field events for the window and returns a value indicating whether window ACCEPT loop processing is complete and should stop. TakeWindowEvent returns Level:Benign to indicate processing of this event should continue normally; it returns Level:Notify to indicate processing is completed for this event and the ACCEPT loop should CYCLE; it returns Level:Fatal to indicate the event could not be processed and the ACCEPT loop should BREAK.
Implementation:
TakeWindowEvent implements standard handling of EVENT:OpenWindow Open method), EVENT:LoseFocus, EVENT:GainFocus (Reset method), and EVENT:Sized (WindowResizeClass.Resize method). Return values are declared in ABERROR.INC.
The TakeEvent method calls the TakeWindowEvent method.
