Comment #4 on issue 313 by alexey@feldgendler.ru: Merge contrib's isFullscreen and doFullFloat to core http://code.google.com/p/xmonad/issues/detail?id=313 The isFullscreen implementation in xmonad-contrib didn't work for me at least with the two applications I tried (MPlayer and Opera). Then I look at the source code of ion3 WM, which used to handle both of them correctly, and saw what it does <http:// ion3.sourcearchive.com/documentation/20060107/fullscreen_8c-source.html> (see clientwin_check_fullscreen_request). I implemented the same in a custom query for XMonad, and it worked. Here is my query: myIsFullscreen = do w <- ask fs <- isFullscreen if fs then return fs else liftX $ do p <- getProp32s "_MOTIF_WM_HINTS" w case p of Just (flags:_:decorations:_) -> return ((flags .&. 2) /= 0 && decorations == 0) Nothing -> return False Please consider merging this into isFullscreen. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
