<hr><a name="details"></a><h2>Detailed Description</h2>
The QColorDialog class provides a dialog widget for specifying colors.
<p> The color dialog's function is to allow users to choose colors.
For example, you might use this in a drawing program to allow the
user to set the brush color.
<p> The static functions provide modal color dialogs.
<p> The static <a href="#getColor">getColor</a>() function shows the dialog and allows the
user to specify a color. The <a href="#getRgba">getRgba</a>() function does the same but
also allows the user to specify a color with an alpha channel
(transparency) value.
<p> The user can store <a href="#customCount">customCount</a>() different custom colors. The
custom colors are shared by all color dialogs, and remembered
during the execution of the program. Use <a href="#setCustomColor">setCustomColor</a>() to set
the custom colors, and use <a href="#customColor">customColor</a>() to get them.

<hr><h2>Member Function Documentation</h2>
<h3 class=fn>QRgb <a name="customColor"></a>QColorDialog::customColor ( int&nbsp;i )<tt> [static]</tt>
</h3>
Returns custom color number <em>i</em> as a QRgb.
<h3 class=fn>int <a name="customCount"></a>QColorDialog::customCount ()<tt> [static]</tt>
</h3>
Returns the number of custom colors supported by QColorDialog. All
color dialogs share the same custom colors.
<h3 class=fn><a href="qcolor.html">QColor</a> <a name="getColor"></a>QColorDialog::getColor ( const&nbsp;<a href="qcolor.html">QColor</a>&nbsp;&amp;&nbsp;initial = white, <a href="qwidget.html">QWidget</a>&nbsp;*&nbsp;parent = 0, const&nbsp;char&nbsp;*&nbsp;name = 0 )<tt> [static]</tt>
</h3>
Pops up a modal color dialog, lets the user choose a color, and
returns that color. The color is initially set to <em>initial</em>. The
dialog is a child of <em>parent</em> and is called <em>name</em>. It returns
an invalid (see <a href="qcolor.html#isValid">QColor::isValid</a>()) color if the user cancels the
dialog. All colors allocated by the dialog will be deallocated
before this function returns.
<p>Examples: <a href="tutorial2-08.html#x2601">chart/setdataform.cpp</a> and <a href="scribble-example.html#x909">scribble/scribble.cpp</a>.
<h3 class=fn>QRgb <a name="getRgba"></a>QColorDialog::getRgba ( QRgb&nbsp;initial, bool&nbsp;*&nbsp;ok = 0, <a href="qwidget.html">QWidget</a>&nbsp;*&nbsp;parent = 0, const&nbsp;char&nbsp;*&nbsp;name = 0 )<tt> [static]</tt>
</h3>
Pops up a modal color dialog to allow the user to choose a color
and an alpha channel (transparency) value. The color+alpha is
initially set to <em>initial</em>. The dialog is a child of <em>parent</em>
and called <em>name</em>.
<p> If <em>ok</em> is non-null, <em>*</em><em>ok</em> is set to TRUE if the user clicked
OK, and to FALSE if the user clicked Cancel.
<p> If the user clicks Cancel, the <em>initial</em> value is returned.
<h3 class=fn>void <a name="setCustomColor"></a>QColorDialog::setCustomColor ( int&nbsp;i, QRgb&nbsp;c )<tt> [static]</tt>
</h3>
Sets custom color number <em>i</em> to the QRgb value <em>c</em>.
<h3 class=fn>void <a name="setStandardColor"></a>QColorDialog::setStandardColor ( int&nbsp;i, QRgb&nbsp;c )<tt> [static]</tt>
</h3>
Sets standard color number <em>i</em> to the QRgb value <em>c</em>.
