Searching for Ruby GUI toolkit, GUI applications

Which GUI toolkit do you think is the most powerful and widely used among ruby programmers? Are there any popular desktop GU开发者_JAVA技巧I applications built in Ruby?

While I cannot comment on "most widely used", Qt4-Ruby is quite powerful: Qt4 Ruby Tutorial. I have used it and like it. On MacOS there is Ruby Cocoa, which seems to be quite popular.

If you're on OSX MacRuby is the thing you want to check out! MacRuby in combination with HotCocoa has excellent support for building cocoa applications, it even works with Interface Builder (an IBOutlet for example is just a matter of declaring attribute accessors in your ruby classes) and is under very active development.

Other than that, I wouldn't necessarily recommend ruby as the first choice for building GUI applications. I'm not saying that it is impossible, but it's just not Rubys primary domain and therefore the community and tool support is far from being optimal. Then again, MacRuby is great and fun to use!

Try out Shoes. It's crossplatform.
