Best GWT widget library? [closed]

Answer 1

Check out SpiffyUI: www.spiffyui.org

It is not just a widget library but complex UI/UX GWT framework.

Answer 2

We have built a large HR portal and a couple of smaller applications using GWT Portlets. The focus of the project is not so much on building a collection of widgets but on creating a simple programming model.

From the website:

GWT Portlets is a free open source web framework for building GWT (Google Web Toolkit) applications. It defines a very simple & productive, yet powerful programming model to build good looking, modular GWT applications.

The programming model is somewhat similar to writing JSR168 portlets for a portal server (Liferay, JBoss Portal etc.). The "portal" is your application built using the GWT Portlets framework as a library. Application functionality is developed as loosely coupled Portlets each with an optional server side DataProvider.

Answer 3

Do NOT use any of them! If you plan to develop a large scale application, you should consider using MVP pattern. The best implementation around is MVP4G framework, it supports GWT code splitting out of box. There are a lot of great examples, you can start with. The most valuable one is Mvp4GModules.

Answer 4

We're currently liking the GWT Mosaic widgets. We've worked with ext-JS and we've rolled our own widgets in the past. ext-JS licensing and bulk were a problem for us. Rolling our own isn't what we want to do. Mosaic gives us a happy middle ground which we like to think will be an even happier middle ground as the project matures.

Answer 5

See this component library GWT Bootstrap this is a implementation in gwt of Twitter Bootstrap.

Answer 6

Not saying it's "the best", but I've been using GWT-Ext at work lately. It's got some pros and cons:

Pros:

• Relatively easy to setup and use
• Decent sized community behind it
• LOTS of examples online, all of which have accompanying code
• Good selection of widgets that cover a wide range of functionality

Cons:

• Makes assumptions about your data's format and structure that you may not be able to accommodate
• Library is just a JSNI wrapper, which makes it harder to debug and extend
• Future support and development on the library is uncertain
• Some annoying cross-browser issues still exist (especially with layouts)
• Search function on their forums is essentially useless. (This is becoming a big pet peeve of mine >_<)
