Overview The goal of the GWT Graphics library is to provide consistent cross-browser vector graphics library for Google Web Toolkit. Under the hood, the library uses to XML-based languages: SVG and VML. VML implementation is for Internet Explorer. Other browsers use SVG implementation.
Please note that GWT Graphics is a library for GWT. If you want to use it with Vaadin, you have to create your own Vaadin widget and use the library on the client-side.
Try the add-on demo at
Official releases of this add-on are available at Vaadin Directory. For Maven instructions, download and reviews, go to http://vaadin.com/addon/GWTGraphics
git clone mvn clean install cd demo mvn jetty:run
To see the demo, navigate to http://localhost:8080/
For further development of this add-on, the following tool-chain is recommended:
- Eclipse IDE
- m2e wtp plug-in (install it from Eclipse Marketplace)
- Vaadin Eclipse plug-in (install it from Eclipse Marketplace)
- JRebel Eclipse plug-in (install it from Eclipse Marketplace)
- Chrome browser
Choose File > Import... > Existing Maven Projects
Note that Eclipse may give "Plugin execution not covered by lifecycle configuration" errors for pom.xml. Use "Permanently mark goal resources in pom.xml as ignored in Eclipse build" quick-fix to mark these errors as permanently ignored in your project. Do not worry, the project still works fine.
If you have not already compiled the widgetset, do it now by running vaadin:install Maven target for GWTGraphics-root project.
If you have a JRebel license, it makes on the fly code changes faster. Just add JRebel nature to your GWTGraphics-demo project by clicking project with right mouse button and choosing JRebel > Add JRebel Nature
To debug project and make code modifications on the fly in the server-side, right-click the GWTGraphics-demo project and choose Debug As > Debug on Server. Navigate to http://localhost:8080/GWTGraphics-demo/ to see the application.
Debugging client side code in the GWTGraphics-demo project:
- run "mvn vaadin:run-codeserver" on a separate console while the application is running
- activate Super Dev Mode in the debug window of the application or by adding ?superdevmode to the URL
- You can access Java-sources and set breakpoints inside Chrome if you enable source maps from inspector settings.
- IE9 uses SVG for rendering now
- JavaDoc enhancements
- GWT Graphics' version can be read from GWT Java code
- Added Animate.onComplete() that is fired when animation completes
- Bug fixes
- Mavenized project
- Color and style (apply patterns) for every step in a path can be changed.
- Vector object's borders can be styled (e.g. to lets say dotted lines or dashes or other patterns).
- Anti-aliasing support added to paths
- A way to add a shadow to a Vector object
- Gradient fill support added
