All Implemented Interfaces:

public class GatePanel

extends javax.swing.JPanel

implements java.awt.event.ComponentListener, java.awt.event.ItemListener, java.awt.event.ActionListener, MathlibEventListener

The GatePanel class is the central class in the qsymbol2 package. It is responsible to bring up a quantum circuit (provided by the GateTable class) with qubit controls, step gauge and computation controls. Basically, everything you see besides the toolbar in the jaQuzzi program is provided by this class.

This class is responsible to add and remove qubits (since it has to update the GateTable as well as the QubitPanel) and therefore implements the MathlibEventListener interface.

It as well implements other interfaces to react to changes in the GateTable or QubitPanel.
