(Updated March 5, 2013, 7:26 p.m.) Review request for kdelibs and David Faure. Changes ------- further testing showed that with this patch everything behaves like it should: KWin is no longer managing the Java Applet windows - neither in Alt+Tab nor in the list of Clients they are shown. When embedding ends they are managed again by KWin. Description (updated) ------- KWindowSystem::doNotMange is a method which performs a D-Bus call to KWin to inform KWin about a window with a specific title to not manage it. Manage here actually meens to set the window to state hidden, but it's nevertheless properly managed and e.g. appears in the Alt+Tab window switcher and is also shown in the taskbar. It's rather obvious that KHTML should not expect the window manager KWin and should not interact with it through D-Bus - after all it's an X11 window manager and we normally talk X. This hack had been added for the Java applet years ago. The reason for this is that the Java windowing system abstraction AWT is too limited. It doesn't allow direct interaction with the window system causing the Applet window to be first mapped to the screen and then getting embedded. This causes a short flicker which is worked around by the doNotManage hack. To suppress this flicker KHTML now sets the appropriate flag and also the flicker is hardly visible anyway because nowadays our computers are much faster ;-) and we have compositing. The doNotManage call clearly falls too short and therefore this change improves the situation by setting the hidden flag and in addition the skip pager and skip taskbar. This at least makes sure that the applets are not shown in the taskbar. Diffs ----- khtml/java/kjavaappletwidget.cpp e9adc4c Diff: http://git.reviewboard.kde.org/r/109282/diff/ Testing ------- installed Java, got it somehow magically configured to even have a plugin, found a website, applet is shown. Thanks, Martin Gräßlin
