I am the abstract superclass of all models of Helios. I am the "Model" part of the MVC pattern implementation in Helios. I provide access to an `Environment` object and both a local (model-specific) and global (system-specific) announcer. The `#withChangesDo:` method is handy for performing model changes ensuring that all widgets are aware of the change and can prevent it from happening.

I provide common methods, additional behavior to widgets useful for Helios, like dialog creation, command execution and tab creation. ## API 1. Rendering Instead of overriding `#renderOn:` as with other Widget subclasses, my subclasses should override `#renderContentOn:`. 2. Refreshing To re-render a widget, use `#refresh`. 3. Key bindings registration and tabs When displayed as a tab, the widget has a chance to register keybindings with the `#registerBindingsOn:` hook method. 4. Unregistration When a widget has subscribed to announcements or other actions that need to be cleared when closing the tab, the hook method `#unregister` will be called by helios. 5. Tabs To enable a widget class to be open as a tab, override the class-side `#canBeOpenAsTab` method to answer `true`. `#tabClass` and `#tabPriority` can be overridden too to respectively change the css class of the tab and the order of tabs in the main menu. 6. Command execution An helios command (instance of `HLCommand` or one of its subclass) can be executed with `#execute:`.! !HLWidget methodsFor: 'accessing'! manager ^ HLManager current ! tabClass ^ self class tabClass ! wrapper ^ wrapper ! ! !HLWidget methodsFor: 'actions'! alert: aString window alert: aString ! confirm: aString ifTrue: aBlock self manager confirm: aString ifTrue: aBlock ! execute: aCommand HLManager current keyBinder activate; applyBinding: aCommand asBinding ! openAsTab HLManager current addTab: (HLTabWidget on: self labelled: self class tabLabel) ! request: aString do: aBlock self manager request: aString do: aBlock ! request: aString value: valueString do: aBlock self manager request: aString value: valueString do: aBlock ! unregister "This method is called whenever the receiver is closed (as a tab).
