<hr><a name="details"></a><h2>Detailed Description</h2>


<p> The TQPalette 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
TQt 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. (TQt 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>().

<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQPalette"></a>TQPalette::TQPalette ()
</h3>
Constructs a palette that consists of color groups with only black
colors.

<h3 class=fn><a name="TQPalette-2"></a>TQPalette::TQPalette ( const&nbsp;<a href="qcolor.html">TQColor</a>&nbsp;&amp;&nbsp;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This function is obsolete.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="TQPalette-3"></a>TQPalette::TQPalette ( const&nbsp;<a href="qcolor.html">TQColor</a>&nbsp;&amp;&nbsp;button, const&nbsp;<a href="qcolor.html">TQColor</a>&nbsp;&amp;&nbsp;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="TQPalette-4"></a>TQPalette::TQPalette ( const&nbsp;<a href="qcolorgroup.html">TQColorGroup</a>&nbsp;&amp;&nbsp;active, const&nbsp;<a href="qcolorgroup.html">TQColorGroup</a>&nbsp;&amp;&nbsp;disabled, const&nbsp;<a href="qcolorgroup.html">TQColorGroup</a>&nbsp;&amp;&nbsp;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">TQColorGroup::ColorRole</a> for definitions of each color role
in the three groups.
<p> <p>See also <a href="qcolorgroup.html">TQColorGroup</a> and <a href="qcolorgroup.html#ColorRole-enum">TQColorGroup::ColorRole</a>.

</h3>
Destroys the palette.

<h3 class=fn>const&nbsp;<a href="qcolorgroup.html">TQColorGroup</a>&nbsp;&amp; <a name="active"></a>TQPalette::active () 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&nbsp;<a href="qcolorgroup.html">TQColorGroup</a>&nbsp;&amp; <a name="disabled"></a>TQPalette::disabled () const
</h3>

<p> Returns the disabled color group of this palette.
<p> <p>See also <a href="qcolorgroup.html">TQColorGroup</a>, <a href="#setDisabled">setDisabled</a>(), <a href="#active">active</a>(), and <a href="#inactive">inactive</a>().

<h3 class=fn>bool <a name="isCopyOf"></a>TQPalette::isCopyOf ( const&nbsp;<a href="qpalette.html">TQPalette</a>&nbsp;&amp;&nbsp;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&nbsp;<a href="qcolorgroup.html">TQColorGroup</a>&nbsp;&amp; <a name="normal"></a>TQPalette::normal () const

</h3>
Returns TRUE (usually tquickly) if this palette is equal to <em>p</em>;
otherwise returns FALSE (slowly).

<h3 class=fn>int <a name="serialNumber"></a>TQPalette::serialNumber () const
</h3>

<p> Returns a number that uniquely identifies this TQPalette object.
The serial number is intended for caching. Its value may not be
used for anything other than equality testing.
<p> Note that TQPalette 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">TQPixmap</a>, <a href="qpixmapcache.html">TQPixmapCache</a>, and <a href="qcache.html">TQCache</a>.
