By default, as a symbol moves in a dashboard diagram,
the link between two symbols connects to the closest ports.
A palette symbol can be designed with elements that can
be used as link-in or link-out ports. Links connected to link-in and
link-out ports stay bound to these ports as the different symbols
move.
Instead of connecting a link to the base shape of a symbol,
you can connect it to a specific element of the symbol defined as
a link port. It is in the Symbol Editor that you can define a symbol
element as an in port, an out port, or an in and out port. See
Using link-in and link-out ports in
Using the Symbol Editor in
Developing with Design Tools for
more information.
When you choose the source symbol of a link, if the mouse
pointer is on a link-out port, this symbol element is highlighted.
When you choose the target symbol of a link, if the mouse pointer
is on a link-in port, this symbol element is highlighted.
