Instance Method


Presents the panel as a sheet modal to the specified window.


func beginSheetModal(for window: NSWindow, completionHandler handler: @escaping (NSApplication.ModalResponse) -> Void)



The window in which the panel will be presented.


The block called after the user dismisses the panel. The argument passed in will be NSFileHandlingPanelOKButton if the user chose the OK button or NSFileHandlingPanelCancelButton if the user chose the Cancel button.


Any properties of the panel you wish to set should be set before calling this method. Although the completion handler block is called after the user dismisses the panel, the panel sheet may still be visible onscreen. If you need to remove the sheet from the screen—for example, if the completion block displays an alert—first call [savePanel orderOut:nil] to close the sheet.
