I'm quite new at cocoa and programming in general, am I got stuck with
trying to get open dialogs to work. Here's the problem:

- (IBAction)editDictionary:(id)sender
{
    [dictionaryWindow makeKeyAndOrderFront:nil];

    NSOpenPanel *openPanel = [NSOpenPanel openPanel];
    SEL sel = @selector(openPanelDidEnd:returnCode:contextInfo:);
    [openPanel beginSheetForDirectory:@"~/Documents" file:@""
modalForWindow:dictionaryWindow modalDelegate:self didEndSelector:sel
contextInfo:nil];
    NSLog(@"Open Dialog Loaded");
}

---

The window would show, but that's it. The program never gets to the
NSLog part. Does anyone have any ideas why it is like this?

Thanks,

Darwin

^^^^^ ^^^^^

Those are your clues that this is a modal operation - that is, it blocks
until it completes.

If you want your code to continue before the open panel session is
completed, use the modeless counterpart, -[NSOpenPanel
beginForDirectory:file:types:modelessDelegate:didEndSelector:contextInfo:]

Thanks, but do you mind explaining what is the difference between the
two and how I can use the modeless counterpart? I'm a bit confused on
what argument is required. Sorry, I'm completely new at this, this can
be fustrating.

Thanks again,

Darwin
