If anyone want to realize cursor like function in your application, you can code like :

```auto
int oldMouseX=0;
int oldMouseY=0;
color oldCorlor;
color colorCursor= color(255,0,0);
color colorCursorTrajectory=color(255,0,255);

boolean bEnableCursorTrajectory=false;//You can set that value to be true, if you want to show cursor trajectory
int CursorSize=10;

void draw() {
  fill(oldCorlor);
  noStroke();
  ellipse(oldMouseX,oldMouseY,CursorSize,CursorSize);
  
  if (bEnableCursorTrajectory){
    stroke(colorCursorTrajectory);
    if (mousePressed == true) {
      strokeWeight(CursorSize);
      strokeCap(ROUND);
      line(mouseX, mouseY, pmouseX, pmouseY); 
    } 
  }
  /**/
  
  //your code here
  
  /**/
  if (mousePressed == true) {
    oldMouseX=mouseX;
    oldMouseY=mouseY;
    oldCorlor=get(oldMouseX,oldMouseY);
    noStroke();
    fill(colorCursor);
    ellipse(mouseX,mouseY,CursorSize,CursorSize); 
  }

}

```
