public class QubitPanel

extends javax.swing.JPanel

class providing a panel with CheckBoxes to set the initial value of a braket. This class is used by the GatePanel class in order to initialize the qubits. The class can provide an extended and simple version of the panel (extended text + icon, simple just icon). The class provides methods to retrieve a Braket from the settings done by the user as well as to initialize the panel. The panel can grow (checkboxes added) and shrink (checkboxes removed).

Constructor Detail

QubitPanel

public QubitPanel(java.awt.event.ItemListener parent,
                  int qubits)

creates a qubit panel in extended mode

QubitPanel

public QubitPanel(java.awt.event.ItemListener parent,
                  int qubits,
                  int complexityMode)

creates a qubit panel in the specified mode

Method Detail

setQubitName

public void setQubitName(int number,
                         java.lang.String name)

sets the name of a qubit in the panel

getQubitName

public java.lang.String getQubitName(int number)

returns the name of a qubit in the panel

setQubitNumber

public void setQubitNumber(int qubits)

sets the qubit number to a given value. If the given number is larger, more checkboxes are added, if the given number is smaller, checkboxes are removed.

getQubitNumber

public int getQubitNumber()

returns the number of checkboxes in the panel

moveQubit

public void moveQubit(int fromRow,
                      int toRow)

moves a checkbox with its label to a given position

removeQubit

public void removeQubit(int number)

removes a given checkbox with label

addQubit

public void addQubit(java.lang.String labelText)

add a checkbox with a label specified by labelText

insertQubit

public void insertQubit(java.lang.String labelName,
                        int row)

inserts a checkbox with a label specified by labelName at position row.

getQubitValue

public Braket getQubitValue()

reset

public void reset()

does nothing right now

setQubitValue

public void setQubitValue(java.util.BitSet bits)

initializes the checkboxes to the pattern given by the BitSet. If a bit in the BitSet is set (==1) than the corresponding checkbox is set to |1>. The lowest order bit in the BitSet sets the lowest order qubit.
