overlay_scrolling

Description:

[ Version ( since = "3.16" ) ]
public bool overlay_scrolling { get; set; }

Whether overlay scrolling is enabled or not.

If it is, the scrollbars are only added as traditional widgets when a mouse is present. Otherwise, they are overlayed on top of the content, as narrow indicators.

Note that overlay scrolling can also be globally disabled, with the GtkSettings::gtk-overlay-scrolling setting.
