    I want to access all of the WebCore classes from a Qt project, starting with Element.
    Examples of why:

    • Access all nodes including text nodes
    • want to access the renderer for a node to get layout info

    Thought this post was relevant but wrong platform, out of date, does not work with MSVC 2010, and had to add DEFINES such as BUILDING_QT_, but I'm still getting compile errors that I don't have the skills to fix.

    If anyone has proven way of achieving this in Qt, or suggestions for change to Qt source, cool! Otherwise anyone done this?
