I would like y’all’s opinions on ease of implementation into Rails, quality and quantity of widgets etc between Yahoo User Interface and Google Web toolkit and ExtJS. I am just getting ready to invest a huge amount of effort into one of them and I would like to know what the community’s experience has been with these toolsets. OR… is there a better open source set of tools for grids and windows and treevews. Thanks in advance ---

I like ExtJS but it has commercial license. YUI and GWT are closer to ExtJS, I am sure they use ExtJs in part of their applications. But I prefer to use FLEX 3 From Adobe, It’s Free, Richer Internet Application than ExtJS and can be Integrated by Ruby on Rails. The weakness, FLEX is supported only by Flash 9. ExtJs and FLEX are good choice to build Web Desktop or Web with RIA. Reinhart [http://teapoci.blogspot.com](http://teapoci.blogspot.com) ---

I like ExtJS a lot. FWIW, they’ve also created a new project that supports GWT. On Jun 9, 8:24 pm, Jeff P. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

I wound up just using CSS and trial and error. jp
