Hi Paul,
It depends how you've set up your event loop.
It sounds like your main event loop is still being called for all
events, and routing the events down to the form, allowing the animation
to run.
The way I dealt with this in 'roids was to have a boolean 'bLive'. When
true, the game ran, when false, it stopped.
The variable was changed when getting a winEnterEvent or winExitEvent
from my main form like so:
if (event.eType != nilEvent) {
if (!SysHandleEvent(&event)){
if (!MenuHandleEvent(0, &event, &error)) {
if (!ApplicationHandleEvent(&event)) {
FrmDispatchEvent(&event);
if (event.eType==winEnterEvent
&& event.data.winEnter.enterWindow ==
(WinHandle)FrmGetFormPtr(frmMain)) {
bLive=true;
}
if (event.eType==winExitEvent
&& event.data.winExit.exitWindow ==
(WinHandle)FrmGetFormPtr(frmMain)) {
bLive=false;
}
} else {
continue;
}
} else {
continue;
}
} else {
continue;
}
}
if (!bLive) {
// Skip the rest of the actions, because the main
// form isn't the topmost form.
continue;
}
