Both of you guys were asking for an answer to approximately the same
question so let me answer both here.
First of all you must realize that a sheet is not "modal" in the same
way that a normal window is. Where normal windows can be modal for the
application, sheets are only modal for their parent window. The
difference from a programming perspective is that you can't just write
one block of code that creates the modal window and blocks until the
modal session ends. Instead, you must tell the sheet to begin and then
use either normal action->target methods to handle the dismissing and
saving of its contents, the didEndSelector, or the modal delegate
functionality.
I will explain the first since it works well in the general case.
To start the NSWindow "sheet" as a sheet for the NSWindow
"parentWindow", use this code:
[NSApp beginSheet:sheet modalForWindow:parentWindow modalDelegate:self
didEndSelector:NULL contextInfo:nil];
To dismiss the sheet (often as the target selector of some button on
the sheet), use this code:
//code to read contents of sheet here
[sheet orderOut:nil];
[NSApp endSheet:sheet];
This will remove the sheet from the window server and tell the
application that it can begin receiving events on the parentWindow
again.
Hope that helps,
Jeff.

that,
the sheet never goes away.
