Hi,

I would like to have a curved connection (like an arc of a circle of a given radius).
Can it be done with a polyline connection or should I implement a connection of my own ?

Thanks,
Emil.

Hello Emil!

GMF allows its users to have curved connections like this:

http://wiki.eclipse.org/images/b/b7/CurvedConnection.JPG

This effect is achieved by changing properties of the EditPart in the Properties View. I chose
Tree for Appearance>Routing>Styles and
More for Appearance>Smoothness

You can try other values to achived the needed effect.
These properties are applied in a class

org.eclipse.gmf.runtime.diagram.ui.editparts.ConnectionEditPart

, methods

installRouter()

and

refreshSmoothness()

respectively. This is a place where you can get an idea how to apply these changes automatically in your code.

Tanya.
