I'm just trying to generate an open panel after a button is pressed. The panel pops up, but then disappears immediately before I can do anything. Here's the code:

Code:

- (void)associatePDFFileWithArticle {

    NSOpenPanel *panel=[NSOpenPanel openPanel];
    [panel beginSheetForDirectory:nil
                             file:nil
                            types:[NSImage imageFileTypes]
                   modalForWindow:nil
                  modalDelegate:self
                   didEndSelector: @selector(openPanelDidEnd:returnCode:contextInfo:)
                      contextInfo:nil];
}


-(void)openPanelDidEnd:(NSOpenPanel *) openPanel
            returnCode:(int)returnCode 
           contextInfo:(void *)x {
    
    NSString *path;
    NSLog(@"panedidend");
    if (returnCode==NSOKButton) {
        path=[openPanel filename];
        
    }
}

thanks,

I think it may be because you're attempting to run it as a sheet, but passing nil as the modalForWindow: paremeter. Maybe you want to use runModalForDirectory:file:types: ?

I'll give that a try. I snagged the above method from Hillegass' book where he says that passing nil will cause the panel to be standalone (which it is for a split second), otherwise it will slide down as a sheet.
