I allready do. And then I call this function (within subclass of

_app = [NSApplication sharedApplication];
_window = [self window];
[_app runModalForWindow:_window];
}
The modal dialog (displayed this way) blocks everything - it is not
possible to close the modal dialog, hit any button or something else.
For me it seems that the NSApplication:: runModalForWindow blocks all.
So what I am searching for is to display the modal dialog without
NSApplication.
I am successfully using modal Cocoa windows in a plugin inside a
Carbon application.
Others have already spoken about the need for NSApplicationLoad() and
setting up an autorelease pool, you definitely have to do both these
things.
To display the window I do this:
//show the window
[window makeKeyAndOrderFront:nil];
//start a modal session and wait for a response
NSModalSession session = [NSApp beginModalSessionForWindow:window];
NSInteger response;
for (;;) {
response=[NSApp runModalSession:session];
if (response != NSRunContinuesResponse)
break;
//
}
//when the user exits the window, hide the window
[NSApp endModalSession:session];
[window close];
You can hook up your OK/cancel buttons something like this:
-(IBAction) ok: (id)sender
{
[NSApp stopModal];
}
-(IBAction) cancel: (id)sender
{
[NSApp abortModal];
}
You can then test for the return value of the NSModalSession and do
whatever you want with the results.
