public class Matrix
extends Container
implements ActionListener, MouseListener, MouseMotionListener, ToolTips
This is the main class for worksheet (matrix) and for simulation. It creates circuit's graph and makes calculations (iterations)

Method Index

o actionPerformed(ActionEvent)
Processes action events occurring on this component.
o addActionListener(ActionListener)
Adds the specified action listener to receive action events from this component.
o buildGraph()
o endSimulation()
o getProbes()
o getTip(int)
Returns tool tip for the matrix.
o getTipLocation(Container)
Returns tool tip location for the matrix.
o loadCircuit(String)
o log()
o makeIteration()
o mouseClicked(MouseEvent)
Handles the mouseClicked event - invokes properties dialog for double clicked element.
o mouseDragged(MouseEvent)
Handles the mouseDragged event - updates event recorder.
o mouseEntered(MouseEvent)
Handles the mouseEntered event.
o mouseExited(MouseEvent)
Handles the mouseExited event - updates tool tips information.
o mouseMoved(MouseEvent)
Handles the mouseMoved event - highlights contacts on mouse over.
o mousePressed(MouseEvent)
Handles the mousePressed event - turns on wire dragging mode.
o mouseReleased(MouseEvent)
Handles the mouseReleased event - runs BFS to connect the wire if possible.
o paint(Graphics)
This method is called to draw this component - update its appearance, if something being dragged over it.
o processMouseEvent(MouseEvent)
o removeActionListener(ActionListener)
Removes the specified action listener so that it no longer receives action events from this component.
o removeWire(Cell)
o reset()
Clear all elements
o sendEvent(String, int)
Function sends event (== command and one argument) to the system.
o startSimulation()
