Method Detail

getParentFrame

public java.awt.Frame getParentFrame()

Description copied from interface: AWTContext

Gets the parent frame of this context to use for the GUI of the application.
An InvalidExecutorThreadException will be thrown if the method is not called by the main thread of the corresponding component.

Specified by:

getParentFrame in interface AWTContext

Returns:

Returns the parent composite which should be used by the Component to draw its GUI.

close

public void close()

Description copied from interface: GUIContext

Closes the GUI for this context. This method has to be called by the runtime manager whenever an application has terminated (finished, failed, aborted, killed,...).
It must be possible to call this method more than once, even if the GUIContext has already shut down. This especially applies to the disposal of SWT-widgets, that is, it is allowed to call this method after the disposal of the corresponding widgets.

Specified by:

close in interface GUIContext
