Tk::ColorEditor(3)    perl/Tk Documentation    Tk::ColorEditor(3)

NAME
       ColorEditor - a general purpose Tk widget Color Editor
       (based on tcolor.tcl from the Tcl/Tk distribution).

SYNOPSIS
	  use Tk::ColorEditor;

	  $cref = $mw->ColorEditor(-title => $title, -cursor => @cursor);

	  $cref->Show;

DESCRIPTION
       ColorEditor is implemented as an object with various
       methods, described below.  First, create your ColorEditor
       object during program initialization (one should be
       sufficient), and then configure it by specifying a list of
       Tk widgets to colorize. When it's time to use the editor,
       invoke the Show() method.

       ColorEditor allows some customization: you may alter the
       color attribute menu by adding and/or deleting menu items
       and/or separators, turn the status window on or off, alter
       the configurator's list of color widgets, or even supply
       your own custom color configurator callback.

       1.  Call the constructor to create the editor object,
	   which in turn returns a blessed reference to the new
	   object:

	      use Tk::ColorEditor;

	      $cref = $mw->ColorEditor(
		  -title  => $title,
		  -cursor => @cursor,
	      );

		 mw	- a window reference, usually the result of a MainWindow->new
			  call.	 As the default root of a widget tree, $mw and all
			  descendant widgets at object-creation-time are configured
			  by the default color configurator procedure.	(You probably
			  want to change this though or you might end up colorizing
			  ColorEditor!)
		 title	- Toplevel title, default = ' '.
		 cursor - a valid Tk '-cursor' specification (default is
			  'top_left_arrow').  This cursor is used over all ColorEditor
			  "hot spots".

       2.  Invoke the configure() method to change editor
	   characteristics:

	      $cref->configure(-option => value, ..., -option-n => value-n);

		 options:
		   -command		: a callback to a  `set_colors' replacement.
		   -widgets		: a reference to a list of widget references
					  for the color configurator.
		   -display_status	: TRUE IFF display the ColorEditor status
					  window when applying colors.
		   -add_menu_item	: 'SEP', or a color attribute menu item.
		   -delete_menu_item	: 'SEP', a color attribute menu item, or color
					  attribute menu ordinal.

	      For example:

		 $cref->configure(-delete_menu_item   => 3,
		     -delete_menu_item	 => 'disabledforeground',
		     -add_menu_item	 => 'SEP',
		     -add_menu_item	 => 'New color attribute',
		     -widgets		 => [$ce, $qu, $f2b2],
		     -widgets		 => [$f2->Descendants],
		     -command		 => [\&my_special_configurator, some, args ]
		 );

       3.  Invoke the Show() method on the editor object, say, by
	   a button or menu press:

	      $cref->Show;

       4.  The cget(-widgets) method returns a reference to a
	   list of widgets that are colorized by the
	   configurator.  Typically, you add new widgets to this
	   list and then use it in a subsequent configure() call
	   to expand your color list.

	      $cref->configure(
		  -widgets => [
		      @{$Filesystem_ref->cget(-widgets)}, @{$cref->cget(-widgets)},
		  ]
	      );

       5.  The delete_widgets() method expects a reference to a
	   list of widgets which are then removed from the
	   current color list.

	      $cref->delete_widgets($OBJTABLE{$objname}->{'-widgets'})
