    \brief The SystemPalette element provides access to the Qt palettes.

    The SystemPalette element provides access to the Qt application
    palettes. This provides information about the standard colors used 
    for application windows, buttons and other features. These colors
    are grouped into three \e {color groups}: \c Active, \c Inactive,
    and \c Disabled.  See the QPalette documentation for details about
    color groups and the properties provided by SystemPalette.

    This can be used to color items in a way that provides a more
    native look and feel.

    The following example creates a palette from the \c Active color
    group and uses this to color the window and text items
    appropriately:
