+    \class TQColorGroup qpalette.h
+    \brief The TQColorGroup class contains a group of widget colors.
+
+    \ingroup appearance
+    \ingroup graphics
+    \ingroup images
+
+    A color group contains a group of colors used by widgets for
+    drawing themselves. We recommend that widgets use color group
+    roles such as "foreground" and "base" rather than literal colors
+    like "red" or "turquoise". The color roles are enumerated and
+    defined in the \l ColorRole documentation.
+
+    The most common use of TQColorGroup is like this:
+
+    \code
+	TQPainter p;
+	...
+	p.setPen( colorGroup().foreground() );
+	p.drawLine( ... )
+    \endcode
+
+    It is also possible to modify color groups or create new color
+    groups from scratch.
+
+    The color group class can be created using three different
+    constructors or by modifying one supplied by TQt. The default
+    constructor creates an all-black color group, which can then be
+    modified using set functions; there's also a constructor for
+    specifying all the color group colors. And there is also a copy
+    constructor.
+
+    We strongly recommend using a system-supplied color group and
+    modifying that as necessary.
+
+    You modify a color group by calling the access functions
+    setColor() and setBrush(), depending on whether you want a pure
+    color or a pixmap pattern.
+
+    There are also corresponding color() and brush() getters, and a
+    commonly used convenience function to get each ColorRole:
+    background(), foreground(), base(), etc.

+/*!
+    \enum TQColorGroup::ColorRole
+
+    The ColorRole enum defines the different symbolic color roles used
+    in current GUIs.
+
+    The central roles are:
+
+    \value Background  general background color.
+
+    \value Foreground  general foreground color.
+
+    \value Base  used as background color for text entry widgets, for example;
+    usually white or another light color.
+
+    \value Text  the foreground color used with \c Base. Usually this
+    is the same as the \c Foreground, in which case it must provide good
+    contrast with \c Background and \c Base.
+
+    \value Button  general button background color in which buttons need a
+    background different from \c Background, as in the Macintosh style.
+
+    \value ButtonText  a foreground color used with the \c Button color.
+
+    There are some color roles used mostly for 3D bevel and shadow
+    effects:
+
+    \value Light  lighter than \c Button color.
+
+    \value Midlight  between \c Button and \c Light.
+
+    \value Dark  darker than \c Button.
+
+    \value Mid  between \c Button and \c Dark.
+
+    \value Shadow  a very dark color.
+    By default, the shadow color is \c TQt::black.
+
+    All of these are normally derived from \c Background and used in
+    ways that depend on that relationship. For example, buttons depend
+    on it to make the bevels look attractive, and Motif scroll bars
+    depend on \c Mid to be slightly different from \c Background.
+
+    Selected (marked) items have two roles:
+
+    \value Highlight   a color to indicate a selected item or the
+    current item. By default, the highlight color is \c TQt::darkBlue.
+
+    \value HighlightedText  a text color that contrasts with \c Highlight.
+    By default, the highlighted text color is \c TQt::white.
+
+    Finally, there is a special role for text that needs to be
+    drawn where \c Text or \c Foreground would give poor contrast,
+    such as on pressed push buttons:
+
+    \value BrightText a text color that is very different from \c
+    Foreground and contrasts well with e.g. \c Dark.
+
+    \value Link a text color used for unvisited hyperlinks.
+    By default, the link color is \c TQt::blue.
+
+    \value LinkVisited a text color used for already visited hyperlinks.
+    By default, the linkvisited color is \c TQt::magenta.
+
+    \value NColorRoles Internal.
+
+    Note that text colors can be used for things other than just
+    words; text colors are \e usually used for text, but it's tquite
+    common to use the text color roles for lines, icons, etc.
+
+    This image shows most of the color roles in use:

+
+    \brief The TQPalette class contains color groups for each widget state.
+
+    \ingroup appearance
+    \ingroup shared
+    \ingroup graphics
+    \ingroup images
+    \mainclass
+
+    A palette consists of three color groups: \e active, \e disabled,
+    and \e inactive. All widgets contain a palette, and all widgets in
+    TQt use their palette to draw themselves. This makes the user
+    interface easily configurable and easier to keep consistent.
+
+    If you create a new widget we strongly recommend that you use the
+    colors in the palette rather than hard-coding specific colors.
+
+    The color groups:
+    \list
+    \i The active() group is used for the window that has keyboard focus.
+    \i The inactive() group is used for other windows.
+    \i The disabled() group is used for widgets (not windows) that are
+    disabled for some reason.
+    \endlist
+
+    Both active and inactive windows can contain disabled widgets.
+    (Disabled widgets are often called \e inaccessible or \e{grayed
+    out}.)
+
+    In Motif style, active() and inactive() look the same. In Windows
+    2000 style and Macintosh Platinum style, the two styles look
+    slightly different.
+
+    There are setActive(), setInactive(), and setDisabled() functions
+    to modify the palette. (TQt also supports a normal() group; this is
+    an obsolete alias for active(), supported for backwards
+    compatibility.)
+
+    Colors and brushes can be set for particular roles in any of a
+    palette's color groups with setColor() and setBrush().
+
+    You can copy a palette using the copy constructor and test to see
+    if two palettes are \e identical using isCopyOf().
