Gets the horizontal Gtk::Scrollable::Policy.

Returns
The horizontal Gtk::Scrollable::Policy.

◆ get_type()

static GType Gtk::Scrollable::get_type ( )
static

Get the GType for this class, for use with the underlying GObject type system.

◆ get_vadjustment() [1/2]

Glib::RefPtr< Adjustment > Gtk::Scrollable::get_vadjustment ( )

Retrieves the Gtk::Adjustment used for vertical scrolling.

Returns
Vertical Gtk::Adjustment.

◆ get_vscroll_policy()

Policy Gtk::Scrollable::get_vscroll_policy ( ) const

Gets the vertical Gtk::Scrollable::Policy.

Returns
