    initial v1  
    442. When video window auto-resize is turned off.
    55
    6 In case of [1], the video widget gets hidden when the play list is activated or when the video is stopped. However, due to some bugs in Qt 4.6.3, it was not actually hidden (unless you specified QT_USE_NATIVE_WINDOWS=1) so it was still visible. The current Qt SVN fixes all these problems, so that it works correctly even w/o QT_USE_NATIVE_WINDOWS=1.

    8 In case of [2], the video widget does not get hidden, it just gets placed behind the play list widget in the widget stack. I don't know why as I didn't look close at VLC sources. And since it is not hidden, it requires overlying widgets to be clipped out when painting on it but nobody does that clipping (because of the lack of WS_CLIPSIBLING flags). So it's a pure clipping problem. Z-order of widgets should be correct.

    1010Adding WS_CLIPCHILDREN to the parent doesn't actually make any sense at all because that would affect parent's clipping, not the video window's one. Only WS_CLIPSIBLINGS matters here but it must be set on all ancestors and their siblings to get the proper effect (and it's a bad idea to do it from KVA since that would interfere with Qt in many regards).
