JRuby swt gem

SWT

This gem contains everything required to write cross-platform desktop applications with JRuby and SWT.

Features:

• Includes all the jar files needed.
• Selects and loads the correct SWT jar for the platform.
• Imports of many swt Java classes into a 1-1 mapped Ruby class hierarchy.
• Examples to get you started. (For more see this SWT cookbook)

Why JRuby/SWT?

• Fast, compatible Ruby implementation.
• JRuby and SWT are flawlessly cross-platform.
• SWT has native widgets (for the most part).
• SWT powers Eclipse, so there's nothing you need that it doesn't do.
• You don't need to touch Java! Write everything in Ruby.
