gtk-sharpGtk# is thread aware, but not thread safe; See the Gtk# Thread Programming for details.Gtk.BinGtk.IScrollableA that allows a scrollable view of its child when added to a .To scroll correctly, a ordinarily requires explicit support from the that will be scrolled. However, a Viewport adds scrolling capabilities to an arbitrary child widget. For example, you can add a collection of widgets to a container. By simply placing the in a Viewport, you need only add the Viewport to a to visually scroll the contents of your Table.The "model" of this widget consists of horizontal and vertical objects. These do not need to be explicitly set to use the Viewport. Packing a child widget as demonstrated in the example, below, is all that is required.The appearance of the Viewport can be adjusted using the property.The following example creates a in a Viewport. When placed in a small , the widgets can be scrolled.
