Method Details

display(self, value=None, **params)

source code 
Display the widget in a Kid template.

Returns an elementtree node instance. If you need serialized output
in a string, call 'render' instead.

Probably you will not need to override or extend if inheriting from
Widget.

@params:

value   : The value to display in the widget.
**params: Extra parameters specific to the widget. All keyword params
          supplied will pass through the update_params method which
          will have a last chance to modify them before reaching the
          template.

Overrides: base.Widget.display
(inherited documentation)
