- .XE
- .LP
- Although widget writers are free to treat
- Core
- as the base class of
- the widget hierarchy, there are actually three classes above it.
- These classes are
- Object,
- RectObj,
- (Rectangle Object) and (\fIunnamed\fP)
- and members of these classes
- are referred to generically as \fIobjects\fP. By convention, the term
- \fIwidget\fP refers only to objects that are a subclass of
- Core,
- and the term \fInonwidget\fP refers to objects that are not a subclass of
- Core.
- In the preceding portion of this specification, the interface
- descriptions indicate explicitly whether the generic \fIwidget\fP argument
- is restricted to particular subclasses of Object. Sections 12.2.5,
- 12.3.5, and 12.5 summarize the permissible classes of the arguments to, and
- return values from, each of the \*(xI routines.

- .LP
- In order not to conflict with previous widget code, the data
- structures used by nonwidget objects do not follow all the same
- conventions as those for widgets. In particular, the class records
- are not composed of parts but instead are complete data structures
- with filler for the widget fields they do not use. This
- allows the static class initializers for existing widgets to remain
- unchanged.

- RectObj
- can be subclassed to provide widgetlike objects (sometimes
- called gadgets) that do not use windows and do not have
- features often unused in simple widgets. This can save memory
- resources both in the server and in applications
- but requires additional support code in the parent.
- In the following
- discussion, \fIrectobj\fP refers only to objects
- whose class is RectObj or a subclass of
- RectObj
- but not Core or a subclass of
- Core.
- .LP
- Composite
- widget classes that wish to accept rectobj children must set
- the \fIaccepts_objects\fP field in the
- .PN CompositeClassExtension
- extension structure to
- .PN True .
- .PN XtCreateWidget
- or
- .PN XtCreateManagedWidget
- will otherwise generate an error if called to create a nonwidget child.
- If the composite widget supports only children of class
- RectObj
- or a subclass (i.e., not of the general Object class), it
- must declare an insert_child procedure and check the subclass of each
- new child in that procedure. None of the classes defined by the
- \*(xI accept rectobj children.
- .LP
- If gadgets are defined in an object set, the parent is responsible for
- much more than the parent of a widget. The parent must request and handle
- input events that occur for the gadget and is responsible for making
- sure that when it receives an exposure event the gadget children get
- drawn correctly.
- Rectobj children may
- have expose procedures
- specified in their class records, but the parent is free to
- ignore them, instead drawing the contents of the child itself. This
- can potentially save graphics context switching. The precise contents
- of the exposure event and region arguments to the RectObj expose
- procedure are not specified by the \*(xI; a particular rectangle object is
- free to define the coordinate system origin (self-relative or
- parent-relative) and whether or not the rectangle or region is assumed to
- have been intersected with the visible region of the object.
- .LP
- In general, it is expected that a composite widget that accepts
- nonwidget children will document those children it is able to handle,
- since a gadget cannot be viewed as a completely self-contained entity,
- as can a widget. Since a particular composite widget class is usually
- designed to handle nonwidget children of only a limited set of classes, it should
- check the classes of newly added children in its insert_child
- procedure to make sure that it can deal with them.
- .LP
- The \*(xI will clear areas of a parent window obscured by
- rectobj children, causing exposure events, under the following
- circumstances:
- .IP \(bu 5
- A rectobj child is managed or unmanaged.
- .IP \(bu 5
- In a call to
- .PN XtSetValues
- on a rectobj child, one or more of the set_values procedures returns
- .PN True .
- .IP \(bu 5
- In a call to

- on a rectobj child, areas will
- be cleared corresponding to both the old and the new child
- geometries, including the border, if the geometry changes.
- .IP \(bu 5
- In a call to
- .PN XtMoveWidget
- on a rectobj child, areas will be
- cleared corresponding to both the old and the new child

- .IP \(bu 5
- In a call to
- .PN XtResizeWidget
- on a rectobj child, an single

- .IP \(bu 5

- on a rectobj child with

- two rectangles will be cleared corresponding to both the old and
- the new child geometries.
- .LP
- Stacking order is not supported for rectobj children. Composite widgets with
- rectobj children are free to define any semantics desired if the child
- geometries overlap, including making this an error.
