public interface Scrollable : Object

Scrollable is an interface that is implemented by widgets with native scrolling ability.

To implement this interface you should override the hadjustment and vadjustment properties.

Creating a scrollable widget

All scrollable widgets should do the following.

  • When a parent widget sets the scrollable child widget’s adjustments, the widget should populate the adjustments’ lower, upper , step_increment, page_increment and page_size properties and connect to the value_changed signal.
  • Because its preferred size is the size for a fully expanded widget, the scrollable widget must be able to cope with underallocations. This means that it must accept any value passed to its size_allocate function.
  • When the parent allocates space to the scrollable child widget, the widget should update the adjustments’ properties with new values.
  • When any of the adjustments emits the value_changed signal, the scrollable widget should scroll its contents.
