How to create a NSPanel modally popuped from NSWindow (Cocoa programming)

like NSPanel displayed after a button clicked in the NSWindow.

I looked for a lot but there is no simple example. Thanks for any help.

Solution

  • It can be done like this:

    -(IBAction)showButtonAction:(id)sender {
    [[NSApplication sharedApplication] beginSheet:panelOutlet
                                   modalForWindow:self.window
                                    modalDelegate:self
                                   didEndSelector:@selector(sheetDidEnd:returnCode:contextInfo:)
                                      contextInfo:nil];
}

    Attention:

    Don't forget to uncheck NSPanel's Visible At Launch checkbox in Attributes Inspector and Release When Closed if you will use this panel not once.
