gwt libraries

Question

Hello! Which GWT library would you suggest I used for a project? Could someone tell me a summary of the pros and cons of various libraries around (SmartGWT, Ext-GWT, GWT-Ext etc.). Is there a best-all-around-library basically "everyone" works with or are some libraries more suited for specific applications than others? Thanks!

Answer 1

GXT is my favourite! It contains also a little MVC implementation and many great widgets.

Answer 2

I have only worked with SmartGWT, so I can't tell something about the other libraries, but maybe this is helpful for you.

PROS

• Datasource concept: The datasource is used to get and send requests. Once it recieves the json or xml data it populates the data to your widgets which are bound to the datasource.

• Documentation: The documentation is really great, every function is well documented and a lot of classes have example code.

• Showcase: the Showcase provides sample code to nearly every widget that is in SmartGWT

• Automatic databound dragging(haven't used it yet): Let's say you have the typical email programm, with a tree and a list of messages, if you drag a message over in a different folder it automatically sends the right request to the server to update the database

• Forums: The Forums aren't as big as the forums from ExtJS but you get an answer from the developers very quick

CONS

• "Just" a wrapper: SmartGWT is a wrapper of the JvaScript Framework Smartclient, so you have to include a lot of JS code which makes the overall size of your application very big. For internal apps that doesn't matter. The size was the reason I switched away from SmartGWT
