WP_Widget is a class that abstracts away much of the complexity involved in writing a widget, especially multi-widgets.

• Basically, you extend WP_Widget with your own class that provides a constructor and three methods -- widget(), form(), and update().
  • widget() - outputs the actual content of the widget.
  • update() - processes options to be saved.
  • form() - outputs the options form.
• A widget is registered by passing the name of the widget class to register_widget().
• All widgets written with WP_Widget are multiple instance capable.
• Options
  • Options for old single-instance widgets ported to WP_Widget will be upgraded to the new multi-option storage format, which is simply a multi-dimensional array keyed by instance ID.
  • Options for widgets using the old multi-instance pattern should work as is.
  • If your widget has custom option storage needs, you can provide your own get_settings() and save_settings() methods.
• The WP_Widget source can be viewed here (read the phpdoc for moreinfo on usage): http://core.trac.wordpress.org/browser/trunk/wp-includes/widgets.php
• You can see examples of how to use it here: http://core.trac.wordpress.org/browser/trunk/wp-includes/default-widgets.php
• If you author any widgets, try porting them to WP_Widget and give your feedback on what can be improved an Trac Ticket 8441.
• Props to the MultiWidget class, on which WP_Widget is based: http://blog.firetree.net/2008/11/30/wordpress-multi-widget/
• The above extracted from Ryan Boren's wp-hackers post.

• Example plugin demonstrates menus with Dashboard, Posts, and Comments in the first menu group. The remaining menus follow in their usual order.
• When filtering the order array, any menus that are not mentioned in the array will be sorted after ones that are mentioned.
• Unmentioned menus are sorted in their usual order, relative to other unmentioned menus.
• Information extracted from Ryan Boren's comments on Trac Ticket 9652
