Question

How can I programmatically force a mac window to be the front window? I have the window handle, and want to ensure that my window is displayed above all other windows. I can use both Carbon & Cocoa for this.

Answer 1

For Cocoa, you can set the window level using:

[window setLevel:NSFloatingWindowLevel];

A floating window will display above all other regular windows, even if your app isn’t active.

If you want to make your app active, you can use:

[NSApp activateIgnoringOtherApps:YES];

and

[window makeKeyAndOrderFront:nil];
