Glimmer DSL for SWT 4.17.7.0 checkbox_group and radio_group Built-In Custom Widgets

Glimmer DSL for SWT 4.17.7.0 ships with the checkbox_group and radio_group Built-In Custom Widgets enabling the spawning of checkboxes and radios automatically with data-binding.

Changes:

• checkbox_group built-in custom widget
• Hello, Checkbox Group! Sample
• Refactor radio_group to render labels instead of relying on radio button text since they are better stylable
• Refactor Glimmer Meta-Sample to use radio_group instead of radio
• Fix issue with ExpandBar fill_layout with the extra element at the end (remove it)

Samples:

Hello, Checkbox Group!

	class HelloCheckboxGroup
	class Person
	attr_accessor :activities
	def initialize
	reset_activities
	end
	def activities_options
	['Skiing', 'Snowboarding', 'Snowmobiling', 'Snowshoeing']
	end
	def reset_activities
	self.activities = ['Snowboarding']
	end
	end
	include Glimmer
	def launch
	person = Person.new
	shell {
	text 'Hello, Checkbox Group!'
	row_layout :vertical
	label {
	text 'Check all snow activities you are interested in:'
	font style: :bold
	}
	checkbox_group {
	selection bind(person, :activities)
	}
	button {
	text 'Reset Activities'
	on_widget_selected do
	person.reset_activities
