I agree with Keith, that "Zen of Palm" dictates that you should allow users
to leave your app at any time and return to it where they left off.
However, if you have a requirement that disables all user inputs for leaving
the application from certain forms and if having POSE send random
appStopEvent calls is a major problem, you can add a call to SysGremlins in
your app event loop right after EvtGetEvent. If you are running in gremlins
and it's an appStopEvent, you can do whatever you want. If you want to
allow appStopEvent from certain forms and exclude it from others, just have
a conditional statement that sets event.eType = nilEvent; to keep the
appStopEvent from being processed.
Make sure to only do this in your debug builds :) You should be using
#define ERROR_CHECK_LEVEL ERROR_CHECK_FULL
for your debug builds, and you can just wrap all the SysGremlins checking
code in #ifdef calls so it will check for gremlins on debug builds, and do
normal processing on release builds. Something like (I don't have the exact
syntax):
#ifdef ERROR_CHECK_LEVEL == ERROR_CHECK_FULL
if (SysGremlins(gremlinIsOn,0)
{
if (FrmGetActiveFormID() == A_FORM_USERS_CAN'T_QUIT_FROM)
event.eType = nilEvent;
}
#endif
