public class QBrick

extends javax.swing.JPanel

this class is used by the GateTable to render one cell. The standard renderer had to be overwritten in order to represent a quantum circuit. The GateTable has one object for each column - a GateContainer. In case of a redraw it calls its CellRenderer, in case of the GateTable the QubitRenderer class. The renderer is responsible for drawing a certain cell. In case of the QubitRenderer, this task is delegated to the QBrick because cells with multiple gates can occur. It is the task of the QBrick class to determine how to draw itself. This is done by the constructor which needs information provided by the JTable class.
