Modal dialogs for fullscreen window (original) (raw)

Hi Vladimir,

A workaround is to not use the exclusive full screen mode, but instead emulate it. Call Window.setAlwaysOnTop(true), and then resize your window to occupy the whole screen area as reported by GraphicsConfiguration.getBounds().

Hi guys,

I'm using in my application fullscreen mode. Since 1.6 java have a lot of issue with it I using X11 native binding for it. Use JNA 3.4. To going to fullscreen I send XSendEvent as NETWMSTATE with NETWMSTATEFULLSCREEN You can look at test application on the github: https://github.com/vkravets/FullScreenTest. Main Class: Main or MinTest So about the issue... I have an issue with modal dialogs or windows which I try to show when my main window in fullscreen mode. From 1.7 java is not working as expected. In 1.6 java modal dialogs/windows appeared above fullscreen window as it should be, but in 1.7 and 1.8 all modal dialogs/windows appeared under the fullscreen window. I'm using wm Metacity, the same I have noticed on Gnome Shell... It seems that it's related to all clones of Metacity... I'm try to see how it's perform by defult native frameworks and I tested GTK3 and SWT which is using GTK bindings. And everything is working as expected. SmartGit which written on Java and use SWT don't have such problem. VLC/GTK the same - in fullscreen mode I can call some dialogs which will be appeared above fullscreen window. It's very strange for me that Java in own documentation have such lines: Quote from GraphicsDevice#setFullScreenWindow: " Windows cannot overlap the full-screen window. All other application windows will always appear beneath the full-screen window in the Z-order. " Since from 1.7 java is using the same message NETWMSTATE with NETWMSTATEFULLSCREEN to going to fullscreeb and is not clear why we have such broken behavior with modal dialogs from 1.7 java and such lines in the documentation.... I'm already posted a defect to Oracle but Ithink it will be marked as duplicate since I found such issue http://bugs.sun.com/bugdatabase/viewbug.do?bugid=7192269 which marked as Not an Issue and for me is not clear why? Could you please suggest workaround? Or please fix this =) Best Regards, Vladimir
