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.

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.

All known implementing classes:

Namespace: Gtk

Package: gtk4

public abstract Adjustment hadjustment { get; set construct; }
Horizontal Adjustment of the scrollable widget.
public abstract ScrollablePolicy hscroll_policy { get; set; }
Determines whether horizontal scrolling should start once the scrollable widget is allocated less than its minimum width or less than its natural width.
public abstract Adjustment vadjustment { get; set construct; }
Vertical Adjustment of the scrollable widget.
public abstract ScrollablePolicy vscroll_policy { get; set; }
Determines whether vertical scrolling should start once the scrollable widget is allocated less than its minimum height or less than its natural height.

public abstract bool get_border (out Border border)
Returns the size of a non-scrolling border around the outside of the scrollable.
public unowned Adjustment get_hadjustment ()
Retrieves the Adjustment used for horizontal scrolling.
public ScrollablePolicy get_hscroll_policy ()
Gets the horizontal ScrollablePolicy.
public unowned Adjustment get_vadjustment ()
Retrieves the Adjustment used for vertical scrolling.
public ScrollablePolicy get_vscroll_policy ()
Gets the vertical ScrollablePolicy.
public void set_hadjustment (Adjustment? hadjustment)
Sets the horizontal adjustment of the Scrollable .
public void set_hscroll_policy (ScrollablePolicy policy)
Sets the ScrollablePolicy to determine whether horizontal scrolling should start below the minimum width or below the natural width.
public void set_vadjustment (Adjustment? vadjustment)
Sets the vertical adjustment of the Scrollable .
public void set_vscroll_policy (ScrollablePolicy policy)
Sets the ScrollablePolicy to determine whether vertical scrolling should start below the minimum height or below the natural height.
