Expand description

View widget driver/binder

The controller binds data items with view widgets.

Note that the key type is not made available since in most cases view widgets are not dependent on the element key. In rare cases where the key is needed, it must be added to the data’s Item type (see data-list-view example).

Several existing implementations are available, most notably:

  • Default will choose a sensible widget to view the data
  • DefaultNav will choose a sensible widget to view the data

Associated Types

Type of message sent by the widget

Type of the widget used to view data

Required methods

Construct a new instance with no data

Such instances are used for sizing and cached widgets, but not shown. The controller may later call Driver::set on the widget then show it.

Set the viewed data
