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. <p> <center><img src="qcolordlg-w.png"></center> <p>See also <a href="dialogs.html">Dialog Classes</a> and <a href="graphics.html">Graphics Classes</a>. <hr><h2>Member Function Documentation</h2> <h3 class=fn>QRgb <a name="customColor"></a>QColorDialog::customColor ( int 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.

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 i, QRgb 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 i, QRgb c )<tt> [static]</tt> </h3> Sets standard color number <em>i</em> to the QRgb value <em>c</em>. <!-- eof --> <hr><p> This file is part of the <a href="index.html">Qt toolkit</a>.
