    00050 // In KAccelEventHandler::x11Event we do our own X11 keyboard event handling
    00051 // This allows us to map the Win key to Qt::MetaButton, Qt does not know about
    00052 // the Win key.
    00053 //
    00054 // KAccelEventHandler::x11Event will generate an AccelOverride event. The
    00055 // AccelOverride event is abused a bit to ensure that KAccelPrivate::eventFilter
    00056 // (as an event filter on the toplevel widget) will get the key event first
    00057 // (in the form of AccelOverride) before any of the intermediate widgets are
    00058 // able to process it.
    00059 //
    00060 // Qt normally sends an AccelOverride, Accel and then a KeyPress event.
    00061 // A widget can accept the AccelOverride event in which case the Accel event will be
    00062 // skipped and the KeyPress is followed immediately.
    00063 // If the Accel event is accepted, no KeyPress event will follow.
    00064 //
    00065 // KAccelEventHandler::x11Event converts a X11 keyboard event into an AccelOverride
    00066 // event, there are now two possibilities:
    00067 //
    00068 // 1) If KAccel intercepts the AccelOverride we are done and can consider the X11
    00069 // keyboard event as handled.
    00070 // 2) If another widget accepts the AccelOverride, it will expect to get a normal
    00071 // Qt generated KeyPress event afterwards. So we let Qt handle the X11 keyboard event
    00072 // again. However, this will first generate an AccelOverride event, and we already
    00073 // had send that one. To compnesate for this, the global event filter in KApplication
    00074 // is instructed to eat the next AccelOveride event. Qt will then send a normal KeyPress
    00075 // event and from then on everything is normal again.
