Here's some clarification (since I realize my original question may not have made very much sense):
I have a button on an NSPreferencePane that executes the following code: NSOpenPanel * open = [NSOpenPanel openPanel]; //basic configuration [NSApp beginSheet:open modalForWindow:[[self mainView] window] delegate:self didEndSelector:@selector(sheetDidEnd:returnCode:contextInfo:) contextInfo:NULL]; When I click the button to execute this code, I get a sheet that looks like this: http://gallery.me.com/davedelong#100084/Screen%20shot%202010-07-09%20at%205.34.22%20PM&bgcolor=black You'll notice that everything is collapsed at the the file browser area is blank. When I try to navigate to a part of the file system within the panel, nothing shows up in the browser area. For example: http://gallery.me.com/davedelong#100084/Screen%20shot%202010-07-09%20at%205.34.37%20PM&bgcolor=black - When I click the "OK" or "Cancel" button, the sheet disappears, but the didEndSelector (as specified above) is never executed. - When I click the original button again (to re-open the sheet), the button's action executes (verifiable via logging, breakpoints, etc), but the sheet never opens. - If I change the NSOpenPanel to display as a modal window (-[NSOpenPanel runModal]) instead of as a sheet, everything works as expected. Summary: something is wrong with my sheet when I use it from within an NSPreferencePane. Question: what's going on, and how do I fix it? Thanks, Dave
