I've seen at least bug report requesting a similar ability for maximization (in particular for some IDE). I'm not sure I'd see why to support fullscreen but not maximization with such a hint. > Let's put it this way - for vmware, where do you want dialogs to open (I > know you can force-override from the app, but assuming you don't do that > and let the WM place them, over what area should they be centered) > > It seems like there are xinerama considerations other than dialog > location but I'm blanking on it right now. Actually, we already have a similar precedent that may be useful. In a dual-monitor xinerama system with metacity, we make desktop windows (such as the one from nautilus) cover both monitors. We got bug reports when nautilus dialogs were split across xineramas. Based on that, I think the answer is that the FULLSCREEN_MONITORS hint (or whatever we call it) should not be inherited by children. Thus, the behavior would be as Lubos suggested earlier: we would not want child dialogs to be split across monitors and thus such dialogs wouldn't necessarily be centered on their parent. > Here's another question - what happens if the user moves the app to > another monitor that isn't a FULLSCREEN_MONITOR (and the app is > fullscreen?) - metacity might allow that unless we also implement some > kind of "fullscreen lock" behavior.

That seems a > little weird. Would the app generally have to keep updating the > FULLSCREEN_MONITOR to the monitor it's currently on? I think these are really good questions. The current suggested hint now bothers me because I can't see how to handle these. Perhaps we should instead have a _NET_WM_FULLSCREEN_AND_MAXIMIZATION_GEOMETRY hint (or some better name with a similar meaning) which consists of a pair of integers and defaults to 1x1. 1x1 means the window fullscreens/maximizes to cover 1 monitor horizontally and 1 monitor vertically. 2x1 would make the window cover both monitors in your typical dual monitor xinerama case. But having 2x1 would also make it clear what to do if you had a three monitor setup and wanted to move the maximized/fullscreen window. Thoughts?
