Status: Verified
SYMPTOM(s):
WINDOW-STATE events appear to have no effect.
The statements:
hWindow:WINDOW-STATE = WINDOW-MINIMIZED.
hWindow:WINDOW-STATE = WINDOW-MAXIMIZED.
hWindow:WINDOW-STATE = WINDOW-RESTORE.
Form:Close().
appear to have no effect as long as session:Set-wait-state("general"). is in effect.
FACT(s) (Environment):
Windows
Progress 9.x
OpenEdge 10.x
CAUSE:
An active SESSION:SET-WAIT-STATE() is blocking the processing of the these window events. When a SESSION:SET-WAIT-STATE() is in affect, user input as well as certain types of internal event processing are blocked. For example, when minimizing a window either by setting the WINDOW-STATE attribute or by applying the WINDOW-MINIMIZED event, Windows sends a message to the window. however, since the window is disabled it cannot process this event. The known events that are affected by this are:
WINDOW-MINIMIZED
WINDOW-MAXIMIZED
WINDOW-RESTORED
Form:Close().
FIX:
Cancel the active WAIT-STATE by executing the statement:
SESSION:SET-WAIT-STATE("")
before executing any of the windows events mentioned above.
