A Gtk# user interface is constructed by nesting widgets inside widgets. widgets are the inner nodes in the resulting tree of widgets: they contain other widgets. So, for example, you might have a containing a containing a . If you wanted an image instead of a textual label inside the frame, you might replace the widget with a widget.
There are two major kinds of widgets in Gtk#. Both are subclasses of the abstract base class.
The first type of widget has a single child widget and derives from . These containers are decorators, which add some kind of functionality to the child. For example, a makes its child into a clickable button; a draws a frame around its child and a places its child widget inside a top-level .
The second type of can have more than one child; its purpose is to manage layout. This means that these containers assign sizes and positions to their children. For example, a arranges its children in a horizontal row, and a arranges the widgets it contains in a two-dimensional grid.
To fulfill its task, a layout must negotiate the size requirements with its parent and its children. This negotiation is carried out in two phases, size requisition and size allocation.

When a receives an expose event, it must send synthetic expose events to all children that do not have their own s. This function provides a convenient way of doing this. A , when it receives an expose event, calls once for each child, passing in the event the received.
takes care of deciding whether an expose event needs to be sent to the child, intersecting the event's area with the child area, and sending the event.
In most cases, a can either simply inherit the expose implementation from , or do some drawing and then chain to the expose implementation from .

In principle each in the chain should be a descendant of the , but this is not enforced by this method, since it is allowed to set the focus chain before you pack the widgets, or have a widget in the chain that is not always packed. The necessary checks are done when the focus chain is actually traversed.
If no focus chain has been explicitly set, gtk# computes the focus chain based on the positions of the children. in that case, gtk# stores in focusable_widgets and returns .
