Hi,
I am developing a diagram application modifiying the
org.eclipse.gef.examples.logic_2.1.0 project behavior. What I particulary
need is to change the wire (connection) behavior.
Currently It is not possible to draw a line (wire) from any point of the
panel to other point. You just can draw a line making a connection from
any part (figure) of the circuit to other.
What I need is to be able to draw a line by clicking the connection
button, click on some point of the panel, fix there the start point of the
line, then by dragging the pointer choose other point of the panel, and
releasing the mouse button, fix there the end point of my line. I am
trying to change EditPolicies but with no succes. Does some body know how
to implement this behavior?
Thanks

You need to draw line figure? I.e. you will draw line, then you want to be

it is a line object, not a connection). If it is so that I can say that I
was unable to find GEF support and implemented it on my own (it took
considerable time, taking into account snapping, feedback painting, etc) -
if you need this functionality you could file a bug to the GEF and I will
try to provide implementation (our is too hard-wired to the model object).

In fact I do need a connection. I'll try to explain myself better.
The scenarion is the following:
When I click the connection button the wire can have the next 3 different
behaviors:
1º- The current behavior. The connection starts from one circuit part
and ends on another circuit part.
2º- clicking on any point of the panel, a default circuit part is drawn
starting from there the connection and ending on any other circuit part.
3º- The connection starts on any circuit part and by droping on any
point of the panel it will draw a default circuit part and ending there
the connection.
Thanks a lot and I hope this is possible to implement.
