    else
        setPaintingDisabled(true);

    m_data = new GraphicsContextPlatformPrivateToplevel(new PlatformContextCairo(cr));
    m_data->m_hdc = dc;
    if (platformContext()->cr()) {
        // Make sure the context starts in sync with our state.
        setPlatformFillColor(fillColor(), fillColorSpace());
        setPlatformStrokeColor(strokeColor(), strokeColorSpace());
    }
    //need to release cario_t reference(GraphicsContextCairoWin.cpp)
