Mousemotion

Question

Is there any way to sence the position of the mouse's cursor in an applet without Swing?

Answer 1

Well I will proceed with what is based on above.
I'll show you now how to create a Polygon (based on your movements)
We use the Polygon class for this purpose:
All code is the same as above (unless changed and noted).
private Polygon shape; // This one must be declared global too
public void init() {
  // As above
  shape = new Polygon();
public void mouseMoved(MouseEvent e) {   
  int x = e.getX();  // Both local variables for this method   
  int y = e.getY();   
  Point p = new Point(x,y);  // Initialize a local variable point   
  points.addElement(p); // Add the point to the vector, note that p, in fact becomes 'global' as it is referenced from the vector now 
  // Here we add the points to the Polygon
  shape.addPoint(x,y);
  repaint();  // Once a point is added re-draw the polygon
// Override the paint method and draw your polygon
// It is however not FAST to do it this way
// But it does show you the idea on how to use the Polygon class
public void paint(Graphics g) {
  g.setColor(Color.BLACK);
  if(shape != null)
    g.drawPolygon(shape);
}To enhance the code you can buffer drawing in memory. (offscreen buffer). There are several postings about this problem, so I suggest to look around if you need it.
The Vector class in this case is not necessary anymore, as you draw the Polygon right away. However if you do not wish to draw the Polygon all the time (which is far better for performance) you can use this one and later create a new polygon and add the Points (that are stored in the Vector class) to the polygon and then draw it.
