Class CompletionImpl

java.lang.Object

java.awt.event.MouseAdapter

org.das2.jythoncompletion.ui.CompletionImpl

All Implemented Interfaces:

java.awt.event.FocusListener, java.awt.event.KeyListener, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.event.MouseWheelListener, java.beans.PropertyChangeListener, java.util.EventListener, javax.swing.event.CaretListener, javax.swing.event.DocumentListener, javax.swing.event.ListSelectionListener

public class CompletionImpl
extends java.awt.event.MouseAdapter
implements javax.swing.event.DocumentListener, javax.swing.event.CaretListener, java.awt.event.KeyListener, java.awt.event.FocusListener, javax.swing.event.ListSelectionListener, java.beans.PropertyChangeListener

Implementation of the completion processing. The visual related processing is done in AWT thread together with completion providers invocation and result set sorting.
The only thing that can be done outside of the AWT is hiding of the completion/documentation/tooltip.

The completion providers typically reschedule computation intensive collecting of their result set into an extra thread to keep the GUI responsive.
