glimmer-dsl-swt VS rubygems

Well, I am happy to announce that the same single line of code that data-binds a table does even more now as of the latest release made yesterday! In Glimmer DSL for SWT v4.24.3.0, that line of code also data-binds the following additional table cell properties without any change to the view code:

There are various limitations, no doubt. I don't mean to imply otherwise. And I am not sure if it is equivalent to shoes (though glimmer-swt may be equivalent, check it out here: https://github.com/AndyObtiva/glimmer-dsl-swt although it also uses java so it's not identical to shoes either).

Glimmer DSL for SWT v4.24.0.2 has been released with the following changes:

SQLite is the simplest relational database to use from JRuby desktop applications, it is built-in on all platforms (Mac, Windows, and Linux), and it can be utilized conveniently via ActiveRecord, the Rails object-relational mapping library following the Active Record Enterprise Application Architecture Pattern. In fact, I have used it a few years ago to build Are We There Yet?, a small project management app, using Glimmer DSL for SWT and bidirectional data-binding. In this blog post tutorial, I cover how to configure a SQLite database and connect to it using ActiveRecord from within a Ruby desktop application, data-binding the ActiveRecord Model to the GUI View bidirectionally.

Native Executable Packaging for CRuby (Glimmer in JRuby already has Native Executable Packaging support for building Mac APP/DMG/PKG files, Windows EXE/MSI files, and Linux DEB/RPM files)

Happy Glimmering!
