-Chapter 6 - Composite and Constraint Widgets
-.XE
-.LP
-These widgets may contain arbitrary widget children. They implement a
-policy for the size and location of their children.
-.IP \fBBox\fP 1i
-.IN "Box widget" ""
-This widget will pack its children as tightly as possible in
-non-overlapping rows.
-.IP \fBDialog\fP 1i
-.IN "Dialog widget" ""
-An implementation of a commonly used interaction semantic to prompt for
-auxiliary input from the user, such as a filename.
-.IP \fBForm\fP 1i
-.IN "Form widget" ""
-A more sophisticated layout widget that allows the children to specify
-their positions relative to the other children, or to the edges of the Form.
-.IP \fBPaned\fP 1i
-.IN "Paned widget" ""
-Allows children to be tiled vertically or horizontally. Controls are
-also provided to allow the user to dynamically resize the individual panes.
-.IP \fBPorthole\fP 1i
-.IN "Porthole widget" ""
-Allows viewing of a managed child which is as large as, or larger than its
-parent, typically under control of a Panner widget.
-.IP \fBTree\fP 1i
-.IN "Tree widget" ""
-Provides geometry management of widgets arranged in a directed, acyclic graph.
-.IP \fBViewport\fP 1i
-.IN "Viewport widget" ""
-Consists of a frame, one or two scrollbars, and an inner window. The
-inner window can contain all the data that is to be displayed. This inner
-window will be clipped by the frame with the scrollbars controlling
-which section of the inner window is currently visible.

-A Brief Note on Geometry Management
-.IN "geometry management" ""
-.LP
-The geometry management semantics provided by the X Toolkit give full
-control of the size and position of a widget to the parent of that
-widget. While the children are allowed to request a certain size or
-location, it is the parent who makes the final decision. Many of the
-composite widgets here will deny any geometry request from their
-children by default. If a child widget is not getting the expected size
-or location, it is most likely the parent disallowing a request, or
-implementing semantics slightly different than those expected by the
-application programmer.
-.LP
-If the application wishes to change the size or location of
-any widget it should make a call to \fBXtSetValues\fP. This will
-.IN "XtSetValues" ""
-allow the widget to ask its parent for the new size or location.
-As noted above the parent is allowed to refuse this request,
-and the child must live with the result. If the
-application is unable to achieve the desired semantics, then perhaps it
-should use a different composite widget. Under no circumstances
-should an application programmer resort to \fBXtMoveWidget\fP or
-.IN "XtMoveWidget" ""
-\fBXtResizeWidget\fP; these functions are exclusively for the use of
-.IN "XtResizeWidget" ""
-Composite widget implementors.
-.LP
-For more information on geometry management consult the \fI\*(xT\fP.
