IUP::ColorDlg - [pre-defined dialog] selecting color
Creates the Color Dialog element. It is a predefined dialog for selecting a color.
There are 3 versions of the dialog. One for Windows only, one for GTK only and one for all systems, but it is based on the IUP::ColorBrowser.
IMPORTANT: In perl IUP bindings only IUP::ColorBrowser based dialog is available (because perl bindings automatically initializes the Controls Library after that the Windows and GTK dialogs are not available anymore).
$colordlg = IUP::ColorDlg->new( VALUE=>"100 100 0" );
Returns: the identifier of the created element, or
undef if an error occurs.
