I got something working and just wanted to run it by y'all. When the
cross-platform init code gets an error, I call a cross-platform function. The
Mac build of this function allocates an NSObject subclass and tells it to
execute later in the main run loop like so:
RunPlogueModalsInMainEventLoop* runner =
[[RunPlogueModalsInMainEventLoop alloc]
initForProblem:PlogueProblem::kEngineFailed error:errCode];
[runner performSelectorOnMainThread:@selector(runDlog)
withObject:runner waitUntilDone:NO modes:[NSArray
arrayWithObjects:NSDefaultRunLoopMode, nil]];
That object's runDlog method then runs our cross-platform dlog and releases the
Obj-C object (self):
-(void) runDlog
{
// Simplified for clarity:
fcdlg::PlogueEngineFailError dlg(NULLP, self->error);
dlg.DoModal();
// We're all done with this allocated object:
[self release];
}
Is this all safe and legal, releasing self right before it returns to whatever
called it?
