Since gtkmm 3.0:

Returns
  Horizontal Gtk::Adjustment.

Glib::RefPtr<const Adjustment> Gtk::Scrollable::get_hadjustment | ( |  | ) | const

Retrieves the Gtk::Adjustment used for horizontal scrolling.

| static

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

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

Retrieves the Gtk::Adjustment used for vertical scrolling.

Since gtkmm 3.0:

Returns

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

Retrieves the Gtk::Adjustment used for vertical scrolling.

Since gtkmm 3.0:

Returns
  Vertical Gtk::Adjustment.

ScrollablePolicy Gtk::Scrollable::get_vscroll_policy | ( |  | ) | const

Gets the vertical Gtk::ScrollablePolicy.

Since gtkmm 3.0:

Returns
  The vertical Gtk::ScrollablePolicy.

GtkScrollable* Gtk::Scrollable::gobj | ( |  | ) |
| inline

Provides access to the underlying C GObject.

const GtkScrollable* Gtk::Scrollable::gobj | ( |  | ) | const
| inline

Provides access to the underlying C GObject.

Scrollable& Gtk::Scrollable::operator= | ( | Scrollable&& | src | ) |
| noexcept

Since gtkmm 3.0:

Returns
  A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< Glib::RefPtr<Adjustment> > Gtk::Scrollable::property_hadjustment | ( |  | ) | const
