Probleme avec state

Bonjour,

Voici ce que j'ai fait pour le moment mais ce n'est point finit. Cependant j'ai une erreur avec mes State :
"Cannot instantiate the type Thread..State"

Code :

import javax.swing.JFrame ;
import javax.swing.BoxLayout;
import javax.swing.JPanel ;
import javax.swing.JColorChooser ;
import javax.swing.Box ;
import javax.swing.BorderFactory ;
import fr.lri.swingstates.canvas.CExtensionalTag;

import java.awt.geom.GeneralPath;
import java.lang.Thread.State;
import java.util.ArrayList ;
public class GraphicalEditor extends JFrame {
private PersistentCanvas canvas ;
private String mode ;
private CanvasItem selection ;
private Point mousepos ;
public static double x;
public static double y;
CStateMachine sm = new CStateMachine(){
public State start = new State(){
Transition t1 = new Press(BUTTON1,"=>drag" ){
public void action(Graphics graphics){
Graphics2D g = (Graphics2D)graphics ;
int arraySize = 3;
int[] xPoints = new int[arraySize];
int[] yPoints = new int[arraySize];
xPoints[0] = (int) GraphicalEditor.x - 12;
yPoints[0] = (int) GraphicalEditor.y;
xPoints[1] = (int) GraphicalEditor.x - 12;
yPoints[1] = (int) GraphicalEditor.y + 50;
xPoints[2] = (int) GraphicalEditor.x - 62;
yPoints[2] = (int) GraphicalEditor.y + 50;
g.drawPolyline(xPoints, yPoints, xPoints.length);
xPoints[0] = (int) GraphicalEditor.x + 12;
yPoints[0] = (int) GraphicalEditor.y;
xPoints[1] = (int) GraphicalEditor.x + 12;
yPoints[1] = (int) GraphicalEditor.y + 50;

yPoints[0] = (int) GraphicalEditor.y + 75;
xPoints[1] = (int) GraphicalEditor.x + 62;
yPoints[1] = (int) GraphicalEditor.y + 75;
g.drawPolyline(xPoints, yPoints, 2);
}
};
};
public State drag = new State(){
Transition t2 = new Drag(){
public void action2(){
}
};
Transition t3 = new ReleaseOnTag(">>strat", BUTTON1){
public void action3(){
}
};
};
};
private ActionListener modeListener = new ActionListener() {
public void actionPerformed(ActionEvent e) {
mode = e.getActionCommand() ;
}
} ;
private ActionListener operationListener = new ActionListener() {
public void actionPerformed(ActionEvent e) {
if (selection==null) return ;
String op = e.getActionCommand() ;
}
} ;
public GraphicalEditor(String theTitle, int width, int height) {
selection = null ;
Container pane = getContentPane() ;
pane.setLayout(new BoxLayout(pane, BoxLayout.LINE_AXIS)) ;
JPanel panel = new JPanel() ;
panel.setLayout(new BoxLayout(panel, BoxLayout.PAGE_AXIS)) ;
panel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10)) ;
mode = "Rectangle" ;
pane.add(panel) ;
canvas = new PersistentCanvas() ;
canvas.setBackground(Color.WHITE) ;
canvas.setPreferredSize(new Dimension(width,height)) ;
pane.add(canvas) ;
canvas.addMouseListener(new MouseAdapter() {
public void mousePressed(MouseEvent e) {
Point p = e.getPoint() ;
x = e.getX();
y=e.getY();
CanvasItem item = null ;
Color o = Color.BLUE ;
Color f = Color.YELLOW ;
item = new RectangleItem(canvas,o,f,p) ;
canvas.addItem(item) ;
select(item) ;
mousepos = p ;
}
}) ;
canvas.addMouseMotionListener(new MouseMotionAdapter() {
public void mouseDragged(MouseEvent e) {
selection.update(e.getPoint()) ;
mousepos = e.getPoint() ;
}
}) ;
pack() ;
setVisible(true) ;
}
private void select(CanvasItem item) {
selection = item ;
if (selection!=null) {
selection.select() ;
}
}
public static void main(String[] args) {
GraphicalEditor editor = new GraphicalEditor("GraphicalEditor",800,600) ;
editor.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) ;
}
}

C'est la première fois que j'utilise une machine à état si quelqu'un pouvait m'aider...
Je possède également une deuxième classe si ca peut aider à comprendre ...

Code :

import java.awt.Component ;
import java.awt.Graphics2D ;
import java.awt.Graphics ;
import java.awt.Point ;
import java.awt.RenderingHints ;
import java.util.ArrayList ;
import fr.lri.swingstates.canvas.CExtensionalTag;
import fr.lri.swingstates.canvas.CPolyLine;
import fr.lri.swingstates.canvas.CStateMachine;
import fr.lri.swingstates.canvas.Canvas;
import fr.lri.swingstates.sm.State;
import fr.lri.swingstates.sm.Transition;
import fr.lri.swingstates.sm.transitions.Drag;
import fr.lri.swingstates.sm.transitions.Press;
import fr.lri.swingstates.sm.transitions.Release;
class PersistentCanvas extends Component {
private ArrayList<CanvasItem> items ;
PersistentCanvas() {
items = new ArrayList<CanvasItem>() ;
}
public CanvasItem addItem(CanvasItem item) {
if (item==null) return null ;
items.add(item) ;
repaint() ;
return item ;
}
public void paint(Graphics graphics) {
Graphics2D g = (Graphics2D)graphics ;
g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON) ;
g.setColor(getBackground()) ;
g.fillRect(0, 0, getWidth(), getHeight()) ;
for (CanvasItem item : items) item.paint(g) ;
}
}

Merci d'avance
