The following code in fltk2.0 makes the compiled program work without
having to be in a "bundle":
// bring the application into foreground without a 'CARB' resource
Boolean same_psn;
ProcessSerialNumber cur_psn, front_psn;
if (!GetCurrentProcess( &cur_psn ) && !GetFrontProcess( &front_psn ) &&
!SameProcess( &front_psn, &cur_psn, &same_psn ) && !same_psn ) {
// If we are in a .app bundle this is not necessary, so don't do it.
// It also prevents some bundle functions such as LSBackgroundOnly.
// This mess figures out if we are bundled:
CFBundleRef bundle = CFBundleGetMainBundle();
if ( bundle ) {
FSRef execFs;
CFURLRef execUrl = CFBundleCopyExecutableURL( bundle );
CFURLGetFSRef( execUrl, &execFs );
FSRef bundleFs;
GetProcessBundleLocation( &cur_psn, &bundleFs );
if ( !FSCompareFSRefs( &execFs, &bundleFs ) )
bundle = NULL;
CFRelease(execUrl);
}
if ( !bundle ) {
OSErr err = 1;
#ifdef MAC_OS_X_VERSION_10_3
// newer supported API
if (TransformProcessType != NULL)
err = TransformProcessType( &cur_psn,
kProcessTransformToForegroundApplication );
#else
// undocumented API
if (CPSEnableForegroundOperation != NULL)
err = CPSEnableForegroundOperation( &cur_psn, 0x03, 0x3C, 0x2C,
0x1103 );
#endif
if (err == noErr)
SetFrontProcess( &cur_psn );
}
