        # QWidgetImage test
        #-------------------------------------------------------------------
        # QWidgetImage still has some issues, some examples are:
        # 
        # 1. Editing in the QTextEdit doesn't work. Also when started with 
        #    --useBrowser, editing in the search field on YouTube doesn't 
        #    work. But that same search field when using QWebViewImage 
        #    works... And editing in the text field in the pop-up getInteger 
        #    dialog works too. All these cases use QGraphicsViewAdapter 
        #    under the hood, so why do some work and others don't?
        #
        #    a) osgQtBrowser --useWidgetImage [--fullscreen] (optional)
        #    b) Try to click in the QTextEdit and type, or to select text
        #       and drag-and-drop it somewhere else in the QTextEdit. These
        #       don't work.
        #    c) osgQtBrowser --useWidgetImage --sanityCheck
        #    d) Try the operations in b), they all work.
        #    e) osgQtBrowser --useWidgetImage --useBrowser [--fullscreen]
        #    f) Try to click in the search field and type, it doesn't work.
        #    g) osgQtBrowser
        #    h) Try the operation in f), it works.
        #
        # 2. Operations on floating windows (--numFloatingWindows 1 or more). 
        #    Moving by dragging the titlebar, clicking the close button, 
        #    resizing them, none of these work. I wonder if it's because the 
        #    OS manages those functions (they're functions of the window 
        #    decorations) so we need to do something special for that? But 
        #    in --sanityCheck mode they work.
        #
        #    a) osgQtBrowser --useWidgetImage --numFloatingWindows 1 [--fullscreen]
        #    b) Try to drag the floating window, click the close button, or
        #       drag its sides to resize it. None of these work.
        #    c) osgQtBrowser --useWidgetImage --numFloatingWindows 1 --sanityCheck
        #    d) Try the operations in b), all they work.
        #    e) osgQtBrowser --useWidgetImage [--fullscreen]
        #    f) Click the button so that the getInteger() dialog is 
        #       displayed, then try to move that dialog or close it with the 
        #       close button, these don't work.
        #    g) osgQtBrowser --useWidgetImage --sanityCheck
        #    h) Try the operation in f), it works.
        #
        # 3. (Minor) The QGraphicsView's scrollbars don't appear when 
        #    using QWidgetImage or QWebViewImage. QGraphicsView is a 
        #    QAbstractScrollArea and it should display scrollbars as soon as
        #    the scene is too large to fit the view.
        #
        #    a) osgQtBrowser --useWidgetImage --fullscreen
        #    b) Resize the OSG window so it's smaller than the QTextEdit.
        #       Scrollbars should appear but don't.
        #    c) osgQtBrowser --useWidgetImage --sanityCheck
        #    d) Try the operation in b), scrollbars appear. Even if you have 
        #       floating windows (by clicking the button or by adding 
        #       --numFloatingWindows 1) and move them outside the view, 
        #       scrollbars appear too. You can't test that case in OSG for 
        #       now because of problem 2 above, but that's pretty cool.
        #
        # 4. (Minor) In sanity check mode, the widget added to the 
        #    QGraphicsView is centered. With QGraphicsViewAdapter, it is not.
        #
        #    a) osgQtBrowser --useWidgetImage [--fullscreen]
        #    b) The QTextEdit and button are not in the center of the image
        #       generated by the QGraphicsViewAdapter.
        #    c) osgQtBrowser --useWidgetImage --sanityCheck
        #    d) The QTextEdit and button are in the center of the 
        #       QGraphicsView.
