Integrating GWT widget with vaadin 7

I would like to integrate ganttchart GWT widget with vaadin7 application available at https://code.google.com/p/gwtgantt/

I went through some links which explores about integrating GWT widgets with vaadin7 but I don't think I understood.

Also, Do I need to write the connector and other stuff in vaadin to integrate GWT widgets? If yes then I am not quite sure what I will be writing in that.

Does anyone tried the same GWT widget with vaadin7 before?

Any pointers or Sample code will be really appreciated.

Regards,
Azhar

When you are able to use Vaadin 7, this wiki article should help you to get started: https://vaadin.com/wiki/-/wiki/Main/Integrating%20an%20existing%20GWT%20widget

I believe it handles exactly what you are asking for.

Basically, you need to write the server side code for GWT widgets, and extends the GWT widgets with the communication capability. Here a good project for you to get start with https://github.com/360-Innovations/VaadinSmartGWT

A little example (for Vaadin 6):

1 use eclipse with Vaadin plugin installed to create a Vaadin project then create Vaadin widget unpon that project, Vaadin plugin will generate all the nuts and bolts.

2 write the code
a client class wrapper for GanttChart It implements Paintable interface to communicate with server side 

    public class VGanttChart extends GanttChart implements Paintable {



     public void paint(PaintTarget target) throws PaintException {

     }

     public void requestRepaint() {

     }

     ... ...

}
for use of each methods, please look at the source comments at Paintable.class
a server side corresponding class:

@ClientWidget(value = VGanttChart.class, loadStyle = LoadStyle.EAGER)
public class GanttChart extends AbstractComponent {

    public void paintContent(PaintTarget target) throws PaintException {

    }


    public void changeVariables(Object source, Map<String, Object> variables) {


    }

    ... ...
}

3 exporting as Vaadin Add-on Package, this is also provided by Vaadin plugin.

4 add the exported jar to your project /WEB-INF/lib, edit your XXXWidgetset.gwt.xml file by adding your add-on's widgetset like this: 

<inherits name="package path to your add-on's widgetset def file"/>
if your widgetset def file is myWidgetset.gwt.xml, then the value for attribute name should be "package path to widgetset"/myWidgetset

5 Compile your Widgetset, this is also provided by Vaadin eclipse plugin, after compilation, new set of javascript, css, image resource was generated, now you can use your add-ons via the server side class.
