Label parallel to Connection [message #249593]

Hi,

I use GMF to create a graphical editor, I have Label with icon in the
middle of my connections, my connections don't have bendpoints.
Then I want my label be parallel to my connection. I can probably use
Transform draw2d class to keep my label rotation angle identical to my
connection rotation angle, but I don't see how to use Transform draw2d
class.

There is a example of his use?

Thanks.

Hi,

There is a method on ConnectionEditPart: installBendpointEditPolicy() that
I'd suggest to override, but it's private. Please raise a bug and we'll
change it's visibility.

Cheers,
Alex

Hi Alex,

I don't know how I can do what I want by overriding
ConnectionEditPart.installBendpointEditPolicy().
Otherwise I should be able to override previously installed
EditPolicy.CONNECTION_BENDPOINTS_ROLE EditPolicy with following code :

installEditPolicy(EditPolicy.CONNECTION_BENDPOINTS_ROLE, new
NullConnectionBendPointEditPolicy());

but this code don't have effect.

Thanks Alex.

Hi Mariot,

Thanks for your tip, now I can do it with GEF but I can't do it with GMF
(see news://news.eclipse.org:119/h3q0kl$p43$1@build.eclipse.org).

Thanks.
