+qt-bugs@ issue : 25122
+applied: no
+author: Lubos Lunak <l.lunak@kde.org>
+
+ Hello,
+
+ for example: Open Konqueror window, showing some files. Start dragging one
+ desktop icon. If you press/release Ctrl, there'll be a '+' attached to the
+ icon, showing the DND operation. Now, while still doing DND, make the
+ Konqueror window active (Alt+Tab with KDE-3.1.2+, hover over its taskbar
+ entry, Ctrl+Fn to switch to a different virtual desktop, etc.). As soon as
+ the app performing DND is not the active application, and the mouse is not
+ moving, pressing/releasing Ctrl doesn't do anything, the state only updates
+ when the mouse is moved.
+
+ This is caused by the fact that Qt has only pointer grab when doing DND, but
+ doesn't have keyboard grab. I actually consider this a good thing, because
+ the only keys important for DND are modifiers, and they come together with
+ pointer events, and not having keyboard grab allows using keyboard shortcuts
+ like Alt+Tab while DND. However, when the mouse is not moved, and only a
+ modifier key is pressed/released, the app won't get any mouse event, and
+ won't also get the keyboard event.
+
+ The attached patch changes Qt to explicitly check the modifiers state using
+ XQueryPointer() if there's wasn't recently any mouse/keyboard event, which
+ ensures the state is updated even in the situation described above.
