Cocoa Sheets

I was struggling with my Photoshop plugin again. The plugin window is modal. But then I need to pop up a modal window, in order to prompt the user for new name/description for the user-saved presets. I was puzzling and Googling, and then I stumbled across a reference to "sheets". Bingo!
This page has the best little example of sheet usage. I was able to copy/paste and then a couple of tweaks, and a couple IB bindings and it all just worked.
- (IBAction)openSheet:(id)sender
{
[NSApp beginSheet: theSheet
modalForWindow: theParent
modalDelegate: self
didEndSelector: @selector(sheetDidEnd: returnCode: contextInfo:)
contextInfo:NULL];
}
- (IBAction)theSheetOK:(id)sender
{
[NSApp endSheet:theSheet returnCode: NSOKButton];
[theSheet orderOut:nil];
}
- (IBAction)theSheetCancel:(id)sender
{
[NSApp endSheet:theSheet returnCode: NSCancelButton];
[theSheet orderOut:nil];
}
- (void)sheetDidEnd:(NSWindow *)sheet returnCode:(int)returnCode contextInfo:(void *)contextInfo
{
if (returnCode == NSOKButton)
NSBeep();
}
I really love code examples that just work.
