Window groups and applications

A window group is the basic unit of an application. Its main functions are:

A typical application will have a single window group, and all its other windows are descendants of that window group. A system shell application may use the RWsSession interface to interrogate all window groups owned by all client applications, and therefore may display a task list. All applications should use the same policy for the format of the window group name. This policy is the responsibility of the GUI, not the window server itself.

An RWindowGroup is a pseudo-window which can never be seen on screen, but which has an ordinal position and participates in parent/child and sibling relationships as all other windows.
