Hi all,
I have a connection EditPart that extends ConnectionNodeEditPart,
this connection have a WrappingLabel, and the edit part of the Wrappinglabel extends LabelEditPart.
The WrappingLabel contains an icon, which I want to rotate to be parallal with the connection.
What I have done is: I put a Listener on the sourceconnectionanchor:
sourceConnectionAnchor.addAnchorListener(this);
and a listener on the targetConnectionAnchor:
targetConnectionAnchor.addAnchorListener(this);
Then I put a code in the anchorMoved method to rotate the icon of the WrappingLabel, when the connection anchors move:
Image iconImage = ((WrappingLabel) figure).getIcon(0);
ImageData data = iconImage.getImageData();
Image image = new Image(PlatformUI.getWorkbench().getDisplay(),
rotate(data, SWT.LEFT));
((WrappingLabel) figure).setIcon(image);
The problem is: When I launch my application, and When I try to move the connection, I have this error:
