<h2>Detailed Description</h2>
<p>The QPalette class contains color groups for each widget state.</p>
<p>A palette consists of three color groups: <i>Active</i>, <i>Disabled</i>, and <i>Inactive</i>. All widgets in Qt contain a palette and use their palette to draw themselves. This makes the user interface easily configurable and easier to keep consistent.</p>
<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>
<p>The color groups:</p>
<ul>
<li>The Active group is used for the window that has keyboard focus.</li>
<li>The Inactive group is used for other windows.</li>
<li>The Disabled group is used for widgets (not windows) that are disabled for some reason.</li>
</ul>
<p>Both active and inactive windows can contain disabled widgets. (Disabled widgets are often called <i>inaccessible</i> or <i>grayed out</i>.)</p>
<p>In most styles, Active and Inactive look the same.</p>
<p>Colors and brushes can be set for particular roles in any of a palette's color groups with <a href="qpalette.html#setColor">setColor</a>() and <a href="qpalette.html#setBrush">setBrush</a>(). A color group contains a group of colors used by widgets for drawing themselves. We recommend that widgets use color group roles from the palette such as "foreground" and "base" rather than literal colors like "red" or "turquoise". The color roles are enumerated and defined in the <a href="qpalette.html#ColorRole-enum">ColorRole</a> documentation.</p>
<p>We strongly recommend that you use a system-supplied color group and modify that as necessary.</p>
<p>To modify a color group you call the functions <a href="qpalette.html#setColor">setColor</a>() and <a href="qpalette.html#setBrush">setBrush</a>(), depending on whether you want a pure color or a pixmap pattern.</p>
<p>There are also corresponding <a href="qpalette.html#color">color</a>() and <a href="qpalette.html#brush">brush</a>() getters, and a commonly used convenience function to get the <a href="qpalette.html#ColorRole-enum">ColorRole</a> for the current <a href="qpalette.html#ColorGroup-enum">ColorGroup</a>: <a href="qpalette-obsolete.html#background">background</a>(), <a href="qpalette-obsolete.html#foreground">foreground</a>(), <a href="qpalette.html#base">base</a>(), etc.</p>
<p>You can copy a palette using the copy constructor and test to see if two palettes are <i>identical</i> using <a href="qpalette.html#isCopyOf">isCopyOf</a>().</p>
<p>QPalette is optimized by the use of <a href="shared.html#implicit-sharing">implicit sharing</a>, so it is very efficient to pass QPalette objects as arguments.</p>
<p>See also <a href="qapplication.html#setPalette">QApplication::setPalette</a>(), <a href="qwidget.html#palette-prop">QWidget::setPalette</a>(), and <a href="qcolor.html">QColor</a>.</p>

<p align="center"><img src="images/palette.png" alt="Color Roles" /></p><p>The ColorRole enum defines the different symbolic color roles used in current GUIs.</p>
<p>The central roles are:</p>
<p><table border="1" cellpadding="2" cellspacing="1" width="100%">
<tr><th width="25%">Constant</th><th width="15%">Value</th><th width="60%">Description</th></tr>
<tr><td valign="top"><tt>QPalette::Window</tt></td><td align="center" valign="top"><tt>10</tt></td><td valign="top">A general background color.</td></tr>
<tr><td valign="top"><tt>QPalette::Background</tt></td><td align="center" valign="top"><tt>Window</tt></td><td valign="top">This value is obsolete. Use Window instead.</td></tr>
<tr><td valign="top"><tt>QPalette::WindowText</tt></td><td align="center" valign="top"><tt>0</tt></td><td valign="top">A general foreground color.</td></tr>
<tr><td valign="top"><tt>QPalette::Foreground</tt></td><td align="center" valign="top"><tt>WindowText</tt></td><td valign="top">This value is obsolete. Use WindowText instead.</td></tr>
<tr><td valign="top"><tt>QPalette::Base</tt></td><td align="center" valign="top"><tt>9</tt></td><td valign="top">Used as the background color for text entry widgets; usually white or another light color.</td></tr>
<tr><td valign="top"><tt>QPalette::AlternateBase</tt></td><td align="center" valign="top"><tt>16</tt></td><td valign="top">Used as the alternate background color in views with alternating row colors (see <a href="qabstractitemview.html#alternatingRowColors-prop">QAbstractItemView::setAlternatingRowColors</a>()).</td></tr>
<tr><td valign="top"><tt>QPalette::Text</tt></td><td align="center" valign="top"><tt>6</tt></td><td valign="top">The foreground color used with <tt>Base</tt>. This is usually the same as the <tt>WindowText</tt>, in which case it must provide good contrast with <tt>Window</tt> and <tt>Base</tt>.</td></tr>
<tr><td valign="top"><tt>QPalette::Button</tt></td><td align="center" valign="top"><tt>1</tt></td><td valign="top">The general button background color. This background can be different from <tt>Window</tt> as some styles require a different background color for buttons.</td></tr>
<tr><td valign="top"><tt>QPalette::ButtonText</tt></td><td align="center" valign="top"><tt>8</tt></td><td valign="top">A foreground color used with the <tt>Button</tt> color.</td></tr>
<tr><td valign="top"><tt>QPalette::BrightText</tt></td><td align="center" valign="top"><tt>7</tt></td><td valign="top">A text color that is very different from <tt>WindowText</tt>, and contrasts well with e.g. <tt>Dark</tt>. Typically used for text that needs to be drawn where <tt>Text</tt> or <tt>WindowText</tt> would give poor contrast, such as on pressed push buttons. Note that text colors can be used for things other than just words; text colors are <i>usually</i> used for text, but it's quite common to use the text color roles for lines, icons, etc.</td></tr>
</table></p>
<p>There are some color roles used mostly for 3D bevel and shadow effects. All of these are normally derived from <tt>Window</tt>, 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 <tt>Mid</tt> to be slightly different from <tt>Window</tt>.</p>
<p><table border="1" cellpadding="2" cellspacing="1" width="100%">

</table></p>
<p>Selected (marked) items have two roles:</p>
<p><table border="1" cellpadding="2" cellspacing="1" width="100%">
<tr><th width="25%">Constant</th><th width="15%">Value</th><th width="60%">Description</th></tr>
<tr><td valign="top"><tt>QPalette::Highlight</tt></td><td align="center" valign="top"><tt>12</tt></td><td valign="top">A color to indicate a selected item or the current item. By default, the highlight color is <a href="qt.html#GlobalColor-enum">Qt::darkBlue</a>.</td></tr>
<tr><td valign="top"><tt>QPalette::HighlightedText</tt></td><td align="center" valign="top"><tt>13</tt></td><td valign="top">A text color that contrasts with <tt>Highlight</tt>. By default, the highlighted text color is <a href="qt.html#GlobalColor-enum">Qt::white</a>.</td></tr>
</table></p>
<p>There are two color roles related to hyperlinks:</p>
<p><table border="1" cellpadding="2" cellspacing="1" width="100%">
<tr><th width="25%">Constant</th><th width="15%">Value</th><th width="60%">Description</th></tr>
<tr><td valign="top"><tt>QPalette::Link</tt></td><td align="center" valign="top"><tt>14</tt></td><td valign="top">A text color used for unvisited hyperlinks. By default, the link color is <a href="qt.html#GlobalColor-enum">Qt::blue</a>.</td></tr>
<tr><td valign="top"><tt>QPalette::LinkVisited</tt></td><td align="center" valign="top"><tt>15</tt></td><td valign="top">A text color used for already visited hyperlinks. By default, the linkvisited color is <a href="qt.html#GlobalColor-enum">Qt::magenta</a>.</td></tr>
</table></p>
<p>Note that we do not use the <tt>Link</tt> and <tt>LinkVisited</tt> roles when rendering rich text in Qt, and that we recommend that you use CSS and the <a href="qtextdocument.html#defaultStyleSheet-prop">QTextDocument::setDefaultStyleSheet</a>() function to alter the appearance of links. For example:</p>
<pre> QTextBrowser browser;
QColor linkColor(Qt::red);
QString sheet = QString::fromLatin1("a { text-decoration: underline; color: %1 }").arg(linkColor.name());
browser.document()->setDefaultStyleSheet(sheet);</pre>
