Класс векторов:
public class FreeVector extends Canvas {
private static final long serialVersionUID = 1L;
Point start;
Point end;
public FreeVector(int startX, int startY, int endX, int endY) {
System.out.println(startX+" "+startY+" "+endX+" "+endY);
start.setLocation(startX, startY);
end.setLocation(endX, endY);
}
public void drawVector(Graphics g) {
g.drawLine((int)start.getX(),(int) start.getY(),(int) end.getX(),(int) end.getY());
}
public Point getEnd() {
return end;
}
public Point getStart() {
return start;
}
Класс, рисующий вектора, в зависимости от стиля рисования:
public class Shape extends Canvas {
private static final int STAR = 1;
private static final int BROKEN_LINE = 2;
private static final int DEFAULT = 3;
private int index = 0;
Collection<FreeVector> vectors = new ArrayList<FreeVector>();
private int coordinateX = 0;
private int coordinateY = 0;
public Shape() {
setBackground(new Color(200, 200, 200));
}
public void paint(Graphics g) {
if(index == STAR) {
g.drawLine(coordinateX, coordinateY, 23, 44);
System.out.println("???");
for (FreeVector vector : vectors) {
System.out.println("!!!");
Point startPoint = vector.getStart();
Point endPoint = vector.getEnd();
System.out.println(startPoint.getX()+" "+startPoint.getY()); g.drawLine((int)startPoint.getX(),(int) startPoint.getY(),(int) endPoint.getX(),(int)endPoint.getY());
}
}
}
public final void drawShape(int styleIndex, int nodeX, int nodeY) {
this.index = styleIndex;
this.coordinateX = nodeX;
this.coordinateY = nodeY;
}
}
У меня даже в цикл не входит
А вектора заполняются так:
addVectorButton.addActionListener(new ActionListener(){
private int startX = 0;
private int startY = 0;
private int endX = 0;
private int endY = 0;
public void actionPerformed(ActionEvent event) {
try {
startX = Integer.parseInt(vectorStartCoordinateX.getText().toString());
startY = Integer.parseInt(vectorStartCoordinateY.getText().toString());
endX = Integer.parseInt(vectorEndCoordinateX.getText().toString());
endY = Integer.parseInt(vectorEndCoordinateY.getText().toString());
new FreeVector(startX,startY,endX,endY);
} catch(Exception e) {
JOptionPane.showMessageDialog(null,"Inserted coordinates are not integers!","Error!",JOptionPane.WARNING_MESSAGE);
return;
}
}
});
