--- Comment #78 from Chituc Georgian dianaxxyyzz@gmail.com --- ----------------------------- Override redirect
Using override redirect is a kind of bazooka with bad side effects, and not at all a good idea if your goal is just to center a window.
If you set the override redirect flag when creating a window, then the window manager won't manage its size, position, stacking order, decorations, or map state (the window manager's redirection of ConfigureRequest and MapRequest is overridden).
This is a really bad idea for anything the user would think of as a window. It's usually used for tooltips and popup menus. If you set override redirect on a window, then all the normal window management UI will be broken, the stacking order will end up basically random (the window will tend to get stuck on top or on bottom, or worse get in an infinite-loop restack fight with another client).
---------------------------- If it is good just for tool tips and popup menus , why in photoshop wine give it to a real window ?
