error with controller.drawStraightArrowConnection() (GWT2.2) #14

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
What is the expected output? What do you see instead?
I'm trying to do the demo code and I obtain an error with the line onnection c1 
= controller.drawStraightArrowConnection(helloLabel, worldLabel);

What version of the product are you using? On what operating system?
I use Eclipse Helios and GWT 2.2.0 and I work with windows XP.

Please provide any additional information below.

My code :
DiagramController controller = new DiagramController(400,400);
        controller.showGrid(true); // Display a background grid
        HorizontalPanel myPanel = new HorizontalPanel();

        Label helloLabel = new Label("Hello");
        controller.addWidget(helloLabel,25,115);

        Label worldLabel = new Label("World");
        controller.addWidget(worldLabel,200,115);

        Connection c1 = controller.drawStraightArrowConnection(helloLabel, worldLabel);

        Widget w = controller.getView();
        myPanel.add(w);
        RootPanel.get().add(myPanel);

Hi
 I faced the same issue. Probably when i worked around, it was happening cause the controller was not yet added in the root panel, yet we were trying to draw connections.

Try 
                Widget w = controller.getView();
        myPanel.add(w);
        RootPanel.get().add(myPanel);
 Connection c1 = controller.drawStraightArrowConnection(helloLabel, worldLabel); 

This ideally drew the exact connection
