The
GUIInitializedListener
interface is used by the
EventQueueMonitor
class to notify an interested party when the GUI subsystem has been
initialized. This is necessary because assistive technologies can
be loaded before the GUI subsystem is initialized. As a result,
assistive technologies should check the
isGUIInitialized
method
of
EventQueueMonitor
before creating any GUI components. If the
return value is true, assistive technologies can create GUI components
following the same thread restrictions as any other application. If
the return value is false, the assistive technology should register
a
GUIInitializedListener
with the
EventQueueMonitor
to be notified
when the GUI subsystem is initialized.
