ScrollableT

gtk.scrollable.Scrollable is an interface for widgets with native scrolling ability.

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 connect to the signal@Gtk.Adjustment::value-changed signal. The child widget should then populate the adjustments’ properties as soon as possible, which usually means queueing an allocation right away and populating the properties in the vfunc@Gtk.Widget.size_allocate implementation.
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 vfunc@Gtk.Widget.size_allocate implementation.
When the parent allocates space to the scrollable child widget, the widget must ensure the adjustments’ property values are correct and up to date, for example using gtk.adjustment.Adjustment.configure.
When any of the adjustments emits the signal@Gtk.Adjustment::value-changed signal, the scrollable widget should scroll its contents.
