Hi
I'm trying to handle when some other app changes to fullscreen by
handling the kEventAppSystemUIModeChanged event.
The event handler is called but then when I check if the menu bar is
visibe I get TRUE!
So I figured, either the apps I'm testing fullscreen mode with (VLC,
Photoshop) don't really enter fullscreen mode as they should like Mac
OS X wants an app too.
Or, the event arrives too early, I even tried putting a 2 seconds
sleep but get the same result - menu is always visible.
I must be doing something wrong here, maybe there is a simpler Cocoa
way?
pascal OSStatus AppEventHandler( EventHandlerCallRef inCallRef,
EventRef inEvent, void* inUserData )
{
#pragma unused( inCallRef, inUserData )
//sleep( 2 );
OSStatus status = eventNotHandledErr;
switch( GetEventClass( inEvent ) )
{
case kEventClassApplication:
{
NSLog( @"kEventClassApplication" );
// check menu visibility, or ui mode
SystemUIMode *outMode;
SystemUIOptions *outOptions;
GetSystemUIMode( outMode, outOptions );
NSLog( @"UI mode: %d %d", *outMode, *outOptions ); // = 0 0
NSLog( @"menu: %d", [NSMenu menuBarVisible] ); // = 1
NSLog( @"menu: %d", IsMenuBarVisible() ); // = 1
status = noErr; // everything went well, event handled
}
break;
default:
{
NSLog( @"..." );
}
break;
}
return status;
}
static const EventTypeSpec sAppEvents[] = { { kEventClassApplication,
kEventAppSystemUIModeChanged } };
InstallApplicationEventHandler( NewEventHandlerUPP( AppEventHandler ),
GetEventTypeCount( sAppEvents ),
sAppEvents, 0, NULL );
Thanks.
Yours sincerely,
Mohsan Khan.
