Invoke a connection tool automatically [message #212877]

All,

Here is my requirement: Given 2 Edit Parts, I need to connect them by
simply clicking on the source anchor (pin) and then the target anchor.
How can I do this?

I have already added the mouselistener interface to my edit parts figure
so I am receiving the mouse pressed events and have done the HitTest work
to make sure the user has clicked on a valid pin. Now the question is how
do I invoke the connection tool from the palette.

Thank you,
Harsh

There's no need to do this from first principles. There is a simple example
in the shapes example.

@see org.eclipse.gef.examples.shapes.parts.ShapeEditPart

Basically, the editpart needs to implement the NodeEditPart interface and
then provide an implementation of the GraphicalNodeEditPolicy on the
EditPolicy.GRAPHICAL_NODE_ROLE.

The tool entry on your palette should utilize the
ConnectionCreationToolEntry.

Steve,

Right now the code is doing what you have outlined. The problem is we
don't want to enable/disable the connection tool manually (I.e. by
selecting from the palette).
