Hi, What do you mean by "have handles to other windows"? Thanks for your reply.

So sad. Can I ask for code-level support? Would that help?

Yes, but I think bounds values aren't enough to tell if a window is fullscreen, right? For example, when the menu bar is hidden, or on a MacBook with a notch, a maximized window is also eligible (the window size is the same as the screen size), but they are not in full-screen mode. Not to mention there is also a split view mode in fullscreen.

Hi, Does this work for all windows in all apps, not just the ones in my app?

Hi, If the window size is equal to the screen size, you can't tell that you are in full-screen mode, especially if the menu bar is set to 'auto-hide' or the device is a MacBook with notch. Am I right?
