Description:
The event manager maintains state information in the bits of
EV_flags
.
EV_OFF — The default event handler sets this flag
when the
2
®
key is pressed. Macro
EV_TST_OFF returns TRUE if this flag is
set. When an application receives the
CM_QUIT event, it can test the EV_OFF
flag to determine if the calculator is being
turned off. The EV_OFF flag will never be
set when any other events are sent to an
app.
EV_SUSPEND_PAINTING — This flag is set by
EV_suspendPainting
and restored by
EV_restorePainting
.
The event manager quits sending
CM_WPAINT messages when this flag is
set, and resumes when this flag is clear.
