<H1><A NAME="description">DESCRIPTION</A></H1>
<P>The method <STRONG>chooseColor</STRONG> is implemented as a perl wrapper
on the core tk ``command'' <STRONG>tk_chooseColor</STRONG>. The <EM>$widget</EM>
is passed as the argument to <STRONG>-parent</STRONG> described below.
The implementation of internal <STRONG>tk_chooseColor</STRONG> is platform
specific, on Win32 it is a native dialog, and on UNIX/X it is implemented
in terms of <A HREF="../../../site/lib/Tk/ColorEditor.html">Tk::ColorEditor</A>.</P>
<P>The core tk command <STRONG>tk_chooseColor</STRONG> pops up a dialog box for the
user to select a color. The following <EM>option-value</EM> pairs are
possible as command line arguments:</P>
<DL>
<DT><STRONG><A NAME="item_%2Dinitialcolor%3D%3Ecolor"><STRONG>-initialcolor</STRONG>=><EM>color</EM></A></STRONG><BR>
<DD>
Specifies the color to display in the color dialog when it pops
up. <EM>color</EM> must be in a form acceptable to the <STRONG>Tk_GetColor</STRONG>
function.
<P></P>
<DT><STRONG><A NAME="item_%2Dparent%3D%3E%24widget"><STRONG>-parent</STRONG>=>$widget</A></STRONG><BR>
<DD>
Makes $widget the logical parent of the color dialog. The color
dialog is displayed on top of its parent window.
<P></P>
<DT><STRONG><A NAME="item_%2Dtitle%3D%3EtitleString"><STRONG>-title</STRONG>=><EM>titleString</EM></A></STRONG><BR>
<DD>
Specifies a string to display as the title of the dialog box. If this
option is not specified, then a default title will be displayed.
<P></P></DL>
<P>If the user selects a color, <STRONG>tk_chooseColor</STRONG> will return the
name of the color in a form acceptable to <STRONG>Tk_GetColor</STRONG>. If the
user cancels the operation, the command will return <STRONG>undef</STRONG>.</P>
