GtkScrollable 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.
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.
GtkAdjustment * gtk_scrollable_get_hadjustment (GtkScrollable *scrollable
);
Retrieves the GtkAdjustment used for horizontal scrolling.

void gtk_scrollable_set_hadjustment (GtkScrollable *scrollable
,GtkAdjustment *hadjustment
);

"hadjustment"
property"hadjustment" GtkAdjustment* : Read / Write / Construct
