    Default QVideoWidget on macos blocks application, need help.

    Hi,

    I have a strange problem with a macos X build, each time I instantiate a QVideoWidget many control elements in the GUI stops working, especially tree controls.

    I noticed that than the application outputs:
    QBackingStore::flush() called with non-exposed window, behavior is undefined

    on windows and linux this problem does not occurs.

    I'm using qt 5.0.2


    does anyone head a seminar issue and may be know how to fix it?

    It seams to be the QTreeWidge only that is affected,

    when I add

    QTreeWidget* tree = new QTreeWidget();
    tree->addTopLevelItem(new QTreeWidgetItem(QStringList("test1")));
    tree->addTopLevelItem(new QTreeWidgetItem(QStringList("test2")));
    tree->addTopLevelItem(new QTreeWidgetItem(QStringList("test3")));
    tree->addTopLevelItem(new QTreeWidgetItem(QStringList("test4")));
    tree->addTopLevelItem(new QTreeWidgetItem(QStringList("test5")));
    hLayout->addWidget(tree);

    to the Qt5.0.2/5.0.2/clang_64/examples/multimediawidgets/player; sample, the tree widget controll is inoperable.

    when i remove player->setVideoOutput(videoWidget);than the controll works but ofcause the player dont.

    I have the same problem but on Windows, as you can see here:
    http://stackoverflow.com/questions/3...application-or
    The inserting of the video widget blocks all buttons and everything within my application!

    Please tell me you have found a solution.

    Cheers,
    Marko
