macOS Modal Window

[sivaprakash]

I am just trying to make my Window as a modal window (that is parent window should not be accessed once this window is launched)

Is this code would do? Anything wrong in this

m_myWindowController = [[MyWindowController alloc] initWithWindowNibName:@"Settings"];    
[m_myWindowController close];    
 [[m_myWindowController window] setParentWindow:self.window];  
[NSApp runModalForWindow:[m_myWindowController window]];

Have a look at the Using Application-Modal Dialogs chapter of the Sheet Programming Topics guide. Also look at the Using Modal Windows chapter of the Window Programming Guide.

But also see your other thread.
