<hr><a name="details"></a><h2>Detailed Description</h2>
<p> The QPalette class contains color groups for each widget state.
<p>
<p> A palette consists of three color groups: <em>active</em>, <em>disabled</em>,
and <em>inactive</em>. 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.
<p> If you create a new widget we strongly recommend that you use the
colors in the palette rather than hard-coding specific colors.
<p> The color groups:
<ul>
<li> The <a href="#active">active</a>() group is used for the window that has <a href="focus.html#keyboard-focus">keyboard focus</a>.
<li> The <a href="#inactive">inactive</a>() group is used for other windows.
<li> The <a href="#disabled">disabled</a>() group is used for widgets (not windows) that are
disabled for some reason.
</ul>
<p> Both active and inactive windows can contain disabled widgets.
(Disabled widgets are often called <em>inaccessible</em> or <em>grayed out</em>.)
<p> In <a href="motif-extension.html#Motif">Motif</a> style, active() and inactive() look the same. In Windows
2000 style and Macintosh Platinum style, the two styles look
slightly different.
<p> There are <a href="#setActive">setActive</a>(), <a href="#setInactive">setInactive</a>(), and <a href="#setDisabled">setDisabled</a>() functions
to modify the palette. (Qt also supports a <a href="#normal">normal</a>() group; this is
an obsolete alias for active(), supported for backwards
compatibility.)
<p> Colors and brushes can be set for particular roles in any of a
palette's color groups with <a href="#setColor">setColor</a>() and <a href="#setBrush">setBrush</a>().
<p> You can copy a palette using the copy constructor and test to see
if two palettes are <em>identical</em> using <a href="#isCopyOf">isCopyOf</a>().
<p> <p>See also <a href="qapplication.html#setPalette">QApplication::setPalette</a>(), <a href="qwidget.html#palette-prop">QWidget::palette</a>, <a href="qcolorgroup.html">QColorGroup</a>, <a href="qcolor.html">QColor</a>, <a href="appearance.html">Widget Appearance and Style</a>, <a href="graphics.html">Graphics Classes</a>, <a href="images.html">Image Processing Classes</a>, and <a href="shared.html">Implicitly and Explicitly Shared Classes</a>.

<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QPalette"></a>QPalette::QPalette ()
</h3>
Constructs a palette that consists of color groups with only black
colors.
<h3 class=fn><a name="QPalette-2"></a>QPalette::QPalette ( const <a href="qcolor.html">QColor</a> & button )
</h3><b>This function is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.
<p> Constructs a palette from the <em>button</em> color. The other colors are
automatically calculated, based on this color. Background will be
the button color as well.
<h3 class=fn><a name="QPalette-3"></a>QPalette::QPalette ( const <a href="qcolor.html">QColor</a> & button, const <a href="qcolor.html">QColor</a> & background )
</h3>
Constructs a palette from a <em>button</em> color and a <em>background</em>.
The other colors are automatically calculated, based on these
colors.
<h3 class=fn><a name="QPalette-4"></a>QPalette::QPalette ( const <a href="qcolorgroup.html">QColorGroup</a> & active, const <a href="qcolorgroup.html">QColorGroup</a> & disabled, const <a href="qcolorgroup.html">QColorGroup</a> & inactive )
</h3>
Constructs a palette that consists of the three color groups <em>active</em>, <em>disabled</em> and <em>inactive</em>. See the <a href="#details">Detailed Description</a> for definitions of the color groups
and <a href="qcolorgroup.html#ColorRole-enum">QColorGroup::ColorRole</a> for definitions of each color role
in the three groups.
<p> <p>See also <a href="qcolorgroup.html">QColorGroup</a> and <a href="qcolorgroup.html#ColorRole-enum">QColorGroup::ColorRole</a>.
<h3 class=fn><a name="QPalette-5"></a>QPalette::QPalette ( const <a href="qpalette.html">QPalette</a> & p )
</h3>
Constructs a copy of <em>p</em>.
<p> This constructor is fast (it uses copy-on-write).
<h3 class=fn><a name="~QPalette"></a>QPalette::~QPalette ()
</h3>
Destroys the palette.
<h3 class=fn>const <a href="qcolorgroup.html">QColorGroup</a> & <a name="active"></a>QPalette::active () const
</h3>
<p> Returns the active color group of this palette.
<p> <p>See also <a href="qcolorgroup.html">QColorGroup</a>, <a href="#setActive">setActive</a>(), <a href="#inactive">inactive</a>(), and <a href="#disabled">disabled</a>().
<p>Examples: <a href="themes-example.html#x290">themes/metal.cpp</a> and <a href="themes-example.html#x224">themes/wood.cpp</a>.

</h3>
Returns the brush in color group <em>gr</em>, used for color role <em>r</em>.
<p> <p>See also <a href="#color">color</a>(), <a href="#setBrush">setBrush</a>(), and <a href="qcolorgroup.html#ColorRole-enum">QColorGroup::ColorRole</a>.
<h3 class=fn>const <a href="qcolor.html">QColor</a> & <a name="color"></a>QPalette::color ( <a href="qpalette.html#ColorGroup-enum">ColorGroup</a> gr, <a href="qcolorgroup.html#ColorRole-enum">QColorGroup::ColorRole</a> r ) const
</h3>
Returns the color in color group <em>gr</em>, used for color role <em>r</em>.
<p> <p>See also <a href="#brush">brush</a>(), <a href="#setColor">setColor</a>(), and <a href="qcolorgroup.html#ColorRole-enum">QColorGroup::ColorRole</a>.
<h3 class=fn><a href="qpalette.html">QPalette</a> <a name="copy"></a>QPalette::copy () const
</h3>
Returns a <a href="shclass.html#deep-copy">deep copy</a> of this palette.
<p> <b>Warning:</b> This is slower than the copy constructor and assignment
operator and offers no benefits.
<h3 class=fn>const <a href="qcolorgroup.html">QColorGroup</a> & <a name="disabled"></a>QPalette::disabled () const
</h3>
<p> Returns the disabled color group of this palette.
<p> <p>See also <a href="qcolorgroup.html">QColorGroup</a>, <a href="#setDisabled">setDisabled</a>(), <a href="#active">active</a>(), and <a href="#inactive">inactive</a>().

</h3>
<p> Returns the inactive color group of this palette.
<p> <p>See also <a href="qcolorgroup.html">QColorGroup</a>, <a href="#setInactive">setInactive</a>(), <a href="#active">active</a>(), and <a href="#disabled">disabled</a>().
<h3 class=fn>bool <a name="isCopyOf"></a>QPalette::isCopyOf ( const <a href="qpalette.html">QPalette</a> & p )
</h3>
Returns TRUE if this palette and <em>p</em> 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.
<p> <p>See also <a href="#operator-eq">operator=</a>() and <a href="#operator-eq-eq">operator==</a>().
<h3 class=fn>const <a href="qcolorgroup.html">QColorGroup</a> & <a name="normal"></a>QPalette::normal () const
</h3>

<p> <p>See also <a href="#setActive">setActive</a>() and <a href="#active">active</a>().
<h3 class=fn>bool <a name="operator!-eq"></a>QPalette::operator!= ( const <a href="qpalette.html">QPalette</a> & p ) const
</h3>
<p> Returns TRUE (slowly) if this palette is different from <em>p</em>;
otherwise returns FALSE (usually quickly).
<h3 class=fn><a href="qpalette.html">QPalette</a> & <a name="operator-eq"></a>QPalette::operator= ( const <a href="qpalette.html">QPalette</a> & p )
</h3>
Assigns <em>p</em> to this palette and returns a reference to this
palette.
<p> This is fast (it uses copy-on-write).
<p> <p>See also <a href="#copy">copy</a>().
<h3 class=fn>bool <a name="operator-eq-eq"></a>QPalette::operator== ( const <a href="qpalette.html">QPalette</a> & p ) const
</h3>
Returns TRUE (usually quickly) if this palette is equal to <em>p</em>;
otherwise returns FALSE (slowly).
<h3 class=fn>int <a name="serialNumber"></a>QPalette::serialNumber () const
</h3>
<p> 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.
<p> Note that QPalette uses copy-on-write, and the serial number
changes during the lazy copy operation (detach()), not during a
<a href="shclass.html#shallow-copy">shallow copy</a> (copy constructor or assignment).
<p> <p>See also <a href="qpixmap.html">QPixmap</a>, <a href="qpixmapcache.html">QPixmapCache</a>, and <a href="qcache.html">QCache</a>.
