Access to the Java Object Layer

The GUIKit framework provides Wolfram Language functions, such as PropertyValue[{"widgetName","propertyName"}], for accessing state or calling methods on JavaObject instances using InvokeMethod[{"widgetName","methodName"},arguments]. However, this does not prevent you from using the standard J/Link techniques for manipulating any underlying JavaObject that makes up the runtime interface.

Here is what this interface will display as on a typical platform.

The first argument of a GUIObject is the root window Java class, in this case a javax.swing.JFrame instance. You can make method calls on this component while the interface is running.

Here is the user interface now. (The interface has been resized to display the entire title.)

WidgetReference[] looks up specially registered instances; such utility GUIObject functions also return JavaObject instances, and so any object in the interface can be accessed directly with J/Link method calls.
