gwt-diagrams with smartGwt?

[GoogleCodeExporter]

What steps will reproduce the problem?
1. gwt-diagram with smartGwt
2.   (attached the onModule code)
3.

What is the expected output? What do you see instead?
A beautiful connection drawn between two smartGwt labels.

What version of the product are you using? On what operating system?
xp
0.2-RC00
smartGwt 1.0b1

Please provide any additional information below.
I tried and found not working.  Went through gwt-diagram source code.  This 
time replaced gwt Panel with smartGwt Canvas.  That didnt help either.

Should I change all usage like 
    setElement(DOM.createDiv());
    addStyleName("gwt-diagrams-connection");
into smartGwt compatible?

Before I try anymore, want to look for directions.
* Is it feasible, easy to adjust a small portion of gwt-diagrams source 
code and use it with smartGwt?  If yes, how?

Thanks

I was able to get a working model after changing some of your files.  Once the 
code 
stabilize, I will upload the jar here.

Thanks for this wonderful piece of tool.

I got few lines are code given here.  They are neither continuous nor related.
Let me know if you have questions.

Connector connector = CanvasConnector.wrap(task.getLabel());
connector.update();
....

Connector task1Connector = CanvasConnector.wrap(parent);
        Connector task2Connector = CanvasConnector.wrap(child);

        // connected already
        if(null != 
RectilinearTwoEndedConnection.getRectilinearTwoEndedConnection(task1Connector, 
task2Connector))
        {
            if(task2Connector != null)
            {   
                task2Connector.update();
            }
            Log.info("Cannot connect again");
            return false;
        }
Connection  connection0 = new RectilinearTwoEndedConnection(task1Connector, 
task2Connector);
connection0.appendTo(topoCanvas);
...

public static void disconnect(Canvas parent, Canvas child) {
        Connector task1Connector = CanvasConnector.wrap(parent);
        Connector task2Connector = CanvasConnector.wrap(child);
        Connection  connection0 =  
RectilinearTwoEndedConnection.getRectilinearTwoEndedConnection(task1Connector, 
task2Connector);

        if(connection0 != null)
            connection0.remove();

RectilinearTwoEndedConnection.delinkRectilinearTwoEndedConnection(task1Connector
, 
task2Connector);
    }

Hi jeya.balaji,

I am able to draw the line within 2 smartGwt label.

But when I dray the label the line not able to redraw. Any advise?

I vaguely remember that the lines did not move along with the label, but at the 
end of 
the drag the lines get adjusted to the new position. 

Is it happening for you?  If you want the line to adjust while dragging, you 
might have 
to change the code; however I tried that before it was not fast enough.  Guess 
the 
logic and the code we are using is not capable of handling that case.

Cool API! Thanks a lot. Got the rectilinear Connection working immediately. 
Added a DropHandler to update the Connection. Works perfectly.

I have the connectors working, but they're not being redrawn immediately on 
dragging.  Has anyone got this to work with drag or drop events yet?

Figured it out.  Add MovedHandler to the items that are connected, and the lien 
is redrawn correctly on dragging.
