Hi , all..
I have created a connection between two figures. What can i do to move the
label along the conn in "every certain distance"?

Here is portion of the code:

PolylineConnection conn = new PolylineConnection();
ChopboxAnchor sourceAnchor = new
ChopboxAnchor(nodeFigure1); ChopboxAnchor targetAnchor = new
ChopboxAnchor(nodeFigure2);
conn.setSourceAnchor(sourceAnchor);
conn.setTargetAnchor(targetAnchor);

Label label = new Label(" ");
label.setOpaque(true);
label.setBackgroundColor(ColorConstants.blue);
label.setVisible(true);

// just display the label located at source
conn.add(label, new ConnectionLocator(conn,2));

Thanks in advance....

Funny I should come across this - I was just working on exactly the same
problem.
I'm not sure a ConnectionLocator is what you want to use...I found that
MidpointLocator works and will locate the label in the middle of the
connection line. Of course, I could be wrong :(
