Steps to reproduce the problem :

1.DiagramController controller = new DiagramController(3000,3000);
2.With no other interaction

If you try to use the controller then the use will be limited as the computer 
is completely slowing down. And make it unusable.

If you use Chrome you can see that there is one processes per tab and so see 
that the tab that make running your server is constantly taking CPU usage and 
memory, enough to slowing down a good computer.

Did you repaint all the time the panel ?

Configs :
gwt-links-1.4.2.jar
GWT 2.4.0
Windows XP pro

What steps will reproduce the problem?
1. Take a BoxLabel and implement your own equals and hashCode
2. Run the application as per normal
3. Drag widgets around


It all works for a while and then I get :

Version : GWT 2.4.0 , GWT 2.3.0
Chrome 11.10.

If I remove the equals and hashCode, it works like a charm.

I suggest documenting this, and maybe fixing the in the future since it's easy 
to work around.

Thanks for a great library! 

I'd like to know how to make DiagramController scrollable, for example in your 
demo when you drag item to any side of the DiagramController it get extended to 
more width/height ? 

Thanks

What steps will reproduce the problem?

Label helloLabel = new Label("hello");
Label goodbyeLabel = new Label("goodbye");
controller.addWidget(helloLabel, 10, 10);
controller.addWidget(goodbyeLabel, 100, 100);
controller.drawStraightArrowConnection(helloLabel, goodbyeLabel);


What is the expected output? What do you see instead?

Two labels, with a line inbetween
Instead, I get that:

What version of the product are you using? On what operating system?

gwt-links from svn
gwt 2.2
firefox 3.6.17 (Ubuntu 10.10)

Please provide any additional information below.
If I remove the line "controller.drawStraightArrowConnection(helloLabel, 
goodbyeLabel);" then everything works fine, I see my two labels on the canvas.

The canvas is extremely slow in chrome dev plugin on linux.  I wonder if this 
is the experience on windows as well.  After compiling to javascript (i.e., 
outside the chrome dev plugin), it's fast.  I tried both multibrowser and html5 
diagram canvas

What steps will reproduce the problem?
1.We are trying to draw a sequence diagram using gwt-links.
2.Draw the diagrams.
3.Load on chrome.

What is the expected output? What do you see instead?
When we try to load the diagrams onto windows chrome, chrome crashes even if 
its just one sequence diagram with around 4-5 objects.

What version of the product are you using? On what operating system?
gwt-links-1.4.1

Please provide any additional information below.

What steps will reproduce the problem?
1.In vertical panel added gwt links DiagramController
2.Added two label widgets in DiagramController. Two labels linked using 
connector.
3.Only IE 8 and 7 connector get shifted below label.

In other browser (FF, chrome) and also IE9 connector links/aligned properly.

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?
IE 8 and 7. I am using gwt-links 1.4.2

Please provide any additional information below.
If you change document mode from standard 8 to standard 7 and back to standard 
8 connector gets aligned properly.

What steps will reproduce the problem?
1. open the demo with Firefox4 
2. try to add links between widgets, the widget hover listener seems like to be 
bad calibrated, also the right click on arrows is affected
3. i can see the orange semicircle appear if i'm out of the widget with my 
mouse pointer and not in the place i should

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?
Firefox4, Mac OSX  SL

Please provide any additional information below.

What steps will reproduce the problem?
1. Connection con = controller.drawStraightArrowConnection(labelHello, hasMenu);

What is the expected output? What do you see instead?
Should be able to specify the destination Arrow shape

What version of the product are you using? On what operating system?
1.3-snapshot

Please provide any additional information below.

Is there a way to specify what shape the Connection link target/destination 
will be?

I made be offbase on this, but there are some common methods in DecorationShape 
and FunctionShape.  Patch makes FunctionShape extend DecorationShape with 
common methods in DecorationShape

right now I think it automatically adds line segments, but you have no way of 
managing them (adding and removing).  They are added automatically when you 
click on a part of the lines and drag, and the only way to remove them is to 
"straighten path"

creation of scroll panel


        AbsolutePanel flowPanelScroll_1=new AbsolutePanel();
        verticalPanel.add(flowPanelScroll_1);
        verticalPanel_1 = new VerticalPanel();

        final ScrollPanel scrollPanel = new ScrollPanel(verticalPanel_1);
        flowPanelScroll_1.add(scrollPanel);
        scrollPanel.setWidth("777px");


        //scrollPanel.setWidget(verticalPanel_1);
        verticalPanel_1.setSize("1485px", "100%");

        FlexTable fltbSpecialistDetails = new FlexTable();
        verticalPanel_1.add(fltbSpecialistDetails);
        fltbSpecialistDetails.setSize("1331px", "20px");

Hello,
I am new to GWT so I have to ask that is gwt-links a Js wrapper around GWT ot 
native GWt implementation ?

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

        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 all,

I'm trying to use shape and abstractShape, plz can you provide me an example?

thanks o lot

Regards

It would be nice to have the possibility to add custom commands to the 
connections contextual menu, apart from setStraight and delete edge.

hi all,
How can I save the graph on DB please,
any suggestions?
thanks a lot
Regards

hi all,
I have a problem with refresh widget, when I draw a boxlabel for example and

           VerticalPanel
                Horizontal panel with buttons ( toolbar )
                DiagramController

The graph will render with the connections mis-aligned ( apparently relative to 
the Scroll panel and not the vertical panel

A graph will render properly WITHOUT the scroll panel however with the scroll 
panel the connections are not draw properly.

See attached example screenshot

What version of the product are you using? On what operating system?
Using gwt-links 1.3 and this is evident in all versions of Firefox and IE

Win XP, IE 8

Please provide any additional information below.

What steps will reproduce the problem?
I've tried the demo code you propose on project home, with Eclipse 3.5 Galileo 
and GWT 2.2

Project Compiles but gives the following runtime exception on SegmentPath class:

java.lang.NullPointerException: null

What is the expected output? What do you see instead?
runtime exception / nothing

What version of the product are you using? On what operating system?

GWT 2.2, both FF 3.6 and Chrome 11.0 on Mac OSX Snow Leopard. 

Please provide any additional information below.

my method of WorkflowTemplates.java

       public void onModuleLoad() {
        DiagramCanvas canvas = new MultiBrowserDiagramCanvas(400,400);
        //DiagramCanvas canvas = new Html5DiagramCanvas(400,400); //for a Html5 implementation
        DiagramController controller = new DiagramController(canvas);
        controller.showGrid(true); // Display a background grid 

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

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

/*LINE 34*/ Connection c1 = controller.drawStraightArrowConnection(helloLabel, 
worldLabel); //PROBLEM HERE

        Label decorationLabel = new Label("Mickey");
        controller.addDecoration(decorationLabel, c1);

        RootPanel.get().add(controller.getView());
    }

Hy everybody,

How could I change the connection color one-bye-one? Because I would like to 
represent the traffic on the graph, where it is going.
I saw the "public static CssColor defaultConnectionColor" variable in the 
source, but it is the class variable.

So it is possible?
Has it any API to do it?

Brs,
Krisz

It would be nice to support different menu bars depending on where the user 
right clicks.  For instance, they may click on the canvas and get a menu to add 
a shape, or they click on a line to straighten it, or they click on a box to 
remove it.

Structure I think would be good is this:

trunk
  -> gwt-links
      -> src
      -> ...
  -> gwt-links-demo
      -> src
      -> ...


Here's an example:

http://code.google.com/p/gxtforms/source/browse/#svn%2Ftrunk%2Fgxtforms%253Fstat
e%253Dclosed

This saves me some eclipse setup .. btw, I have more suggestions on this front.

also I believe GwtLinksStyle.css contains an error

should be     filter:alpha(opacity=30);
and remove the other lines with the comments for IE8
