Connecting graphicals
Connections define a line connecting two graphical
objects. Changing either of the graphical
objects will update the connection automatically.
The END-POINTS of the connections on each of the graphicals is
determined using a HANDLE. A handle has a name and a kind.
The
name of a handle should be unique over all handles attached
to a graphical. The kind need not be unique. Each side of a
connection can attach to a handle of specified type and possible only
with a given name. When only the kind is determined and there are more
than one handle of the specified kind, the connection will attach to
that handle that looks best. Handles can be attached both
at the class level using class->handle
or at the instance level using‘Graphical
->handle’.
The initial ATTRIBUTES of the line (arrows, pen, texture) may be
instantiated from a link. See E Linking Graphicals.
