DESCRIPTION
       The QPalette class contains color groups for each widget state.

       A palette consists of three color groups: active, disabled, and inactive. All widgets
       contain a palette, and all widgets in Qt 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:

       The active() group is used for the window that has keyboard focus.

       The inactive() group is used for other windows.

       The disabled() group is used for widgets (not windows) that are disabled for some reason.

       Both active and inactive windows can contain disabled widgets. (Disabled widgets are often
       called inaccessible or 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.
       (Qt 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
       identical using isCopyOf().

       See also QApplication::setPalette(), QWidget::palette, QColorGroup, QColor, Widget
       Appearance and Style, Graphics Classes, Image Processing Classes, and Implicitly and
       Explicitly Shared Classes.

MEMBER FUNCTION DOCUMENTATION
QPalette::QPalette ()
       Constructs a palette that consists of color groups with only black colors.

QPalette::QPalette ( const QColor & button )
       This function is obsolete. It is provided to keep old source working. We strongly advise
       against using it in new code.

       Constructs a palette from the button color. The other colors are automatically calculated,
       based on this color. Background will be the button color as well.

QPalette::QPalette ( const QColor & button, const QColor & background )
       Constructs a palette from a button color and a background. The other colors are
       automatically calculated, based on these colors.

QPalette::QPalette ( const QColorGroup & active, const QColorGroup & disabled, const QColorGroup
       & inactive )
       Constructs a palette that consists of the three color groups active, disabled and
       inactive. See the Detailed Description for definitions of the color groups and
       QColorGroup::ColorRole for definitions of each color role in the three groups.

       See also QColorGroup and QColorGroup::ColorRole.

QPalette::QPalette ( const QPalette & p )
       Constructs a copy of p.

       This constructor is fast (it uses copy-on-write).

QPalette::~QPalette ()
       Destroys the palette.

const QColorGroup &; QPalette::active () const
       Returns the active color group of this palette.

       See also QColorGroup, setActive(), inactive(), and disabled().

       Examples:

const QBrush &; QPalette::brush ( ColorGroup gr, QColorGroup::ColorRole r ) const
       Returns the brush in color group gr, used for color role r.

       See also color(), setBrush(), and QColorGroup::ColorRole.

const QColor &; QPalette::color ( ColorGroup gr, QColorGroup::ColorRole r ) const
       Returns the color in color group gr, used for color role r.

       See also brush(), setColor(), and QColorGroup::ColorRole.

QPalette QPalette::copy () const
       Returns a deep copy of this palette.

       Warning: This is slower than the copy constructor and assignment operator and offers no
       benefits.

const QColorGroup &; QPalette::disabled () const
       Returns the disabled color group of this palette.

       See also QColorGroup, setDisabled(), active(), and inactive().

       Examples:

const QColorGroup &; QPalette::inactive () const
       Returns the inactive color group of this palette.

       See also QColorGroup, setInactive(), active(), and disabled().

bool QPalette::isCopyOf ( const QPalette & p )
       Returns TRUE if this palette and p are copies of each other, i.e. one of them was created
       as a copy of the other and neither was subsequently modified; otherwise returns FALSE.
       This is much stricter than equality.

       See also operator=() and operator==().

const QColorGroup &; QPalette::normal () const
       This function is obsolete. It is provided to keep old source working. We strongly advise
       against using it in new code.

       Returns the active color group. Use active() instead.

       See also setActive() and active().

bool QPalette::operator!= ( const QPalette & p ) const
       Returns TRUE (slowly) if this palette is different from p; otherwise returns FALSE
       (usually quickly).

QPalette &; QPalette::operator= ( const QPalette & p )
       Assigns p to this palette and returns a reference to this palette.

       This is fast (it uses copy-on-write).

       See also copy().

bool QPalette::operator== ( const QPalette & p ) const
       Returns TRUE (usually quickly) if this palette is equal to p; otherwise returns FALSE
       (slowly).

int QPalette::serialNumber () const
       Returns a number that uniquely identifies this QPalette object. The serial number is
       intended for caching. Its value may not be used for anything other than equality testing.

       Note that QPalette uses copy-on-write, and the serial number changes during the lazy copy
       operation (detach()), not during a shallow copy (copy constructor or assignment).

       See also QPixmap, QPixmapCache, and QCache.

void QPalette::setActive ( const QColorGroup & g )
       Sets the Active color group to g.

       See also active(), setDisabled(), setInactive(), and QColorGroup.

void QPalette::setBrush ( ColorGroup gr, QColorGroup::ColorRole r, const QBrush & b )
       Sets the brush in color group gr, used for color role r, to b.

       See also brush(), setColor(), and QColorGroup::ColorRole.

void QPalette::setBrush ( QColorGroup::ColorRole r, const QBrush & b )
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Sets the brush in for color role r in all three color groups to b.

       See also brush(), setColor(), QColorGroup::ColorRole, active(), inactive(), and
       disabled().

void QPalette::setColor ( ColorGroup gr, QColorGroup::ColorRole r, const QColor & c )
       Sets the brush in color group gr, used for color role r, to the solid color c.

       See also setBrush(), color(), and QColorGroup::ColorRole.

       Example: themes/themes.cpp.

void QPalette::setColor ( QColorGroup::ColorRole r, const QColor & c )
       This is an overloaded member function, provided for convenience. It behaves essentially
       like the above function.

       Sets the brush color used for color role r to color c in all three color groups.

       See also color(), setBrush(), and QColorGroup::ColorRole.

void QPalette::setDisabled ( const QColorGroup & g )
       Sets the Disabled color group to g.

       See also disabled(), setActive(), and setInactive().

void QPalette::setInactive ( const QColorGroup & g )
       Sets the Inactive color group to g.

       See also active(), setDisabled(), setActive(), and QColorGroup.

void QPalette::setNormal ( const QColorGroup & cg )
       This function is obsolete. It is provided to keep old source working. We strongly advise
       against using it in new code.

       Sets the active color group to cg. Use setActive() instead.

       See also setActive() and active().

RELATED FUNCTION DOCUMENTATION
QDataStream &; operator<< ( QDataStream & s, const QPalette & p )

       See also Format of the QDataStream operators.

QDataStream &; operator>> ( QDataStream & s, QPalette & p )
       Reads a palette from the stream, s into the palette p, and returns a reference to the
       stream.

       See also Format of the QDataStream operators.
