Hmm, good catch.  I'll have to check, but I suspect the window no longer remembers its title at that point.  And the Mac driver doesn't currently store it anywhere else.  So, we may need to do so in order to restore it.


>> Also, if the Windows program changes a window from resizable to non-resizable, then we should probably pull the window out of Cocoa fullscreen.  The Windows program _may_ have intended to make the window full-screen but we can't know that.  It may simply be changing the window style for some other purpose, and that may make it no longer a candidate for Cocoa full-screen mode.

Yeah.  It may make for a poor user experience to force the window out of Cocoa full-screen, especially if it's just going to go Windows full-screen right afterward, but I think it's probably necessary.  I think it's a relatively rare occurrence, anyway.


>> I disagree.  Windows programs that are not expecting their window to resize (because they haven't made them resizable) can misbehave badly if the window does resize.  Just because that didn't happen in your testing doesn't mean it won't.

Well, that's how it works on Windows.  And the X11 driver in Wine.  And native Mac apps.  (Open TextEdit.  Its window has all the buttons enabled and can be resized.  Open the modal Open dialog.  The document window still has all its buttons and, on 10.6, the grow box, but they're disabled.  On 10.7+, the resize cursors around the edge still show, but they're ineffective.  I suppose we can achieve that same effect by not using the min and max sizes to prevent resize but do it by overriding -windowWillResize:toSize:, but I prefer it to be obviously not resizable.)

The main reason is that some Windows apps will probably freak out if their windows get resized, closed, or minimized when they're supposed to be disabled.


>> I don't follow this.  It is possible to resize any window even non-resizable ones?  To what are you referring?  Possible how?  Do you mean specifically just with this full-screen patch?

Sure, but Wine is aiming for compatibility with Windows apps, so the "not freaking out" thing is kind of a big deal. ;)
