I have various applets onto the base PApplet.Now I want to know the intersection point of cursor with the child applets.

Now to check if the cursor is within a perticular applet,  I took the cursor points as :

1.  withinApp= checkBounds(tcur.getScreenX(parentPApplet.width ),tcur.getScreenY(parentPApplet.height)); 
2.  
3. boolean checkBounds(float X,float Y)
4.  {
5.    float leftX = this.getPositionX();  //upper left X of applet
   
6.    float leftY = this.getPositionY(); //upper left Y of applet
   
7.  
8.    if( X>leftX && Y >leftY && ( X < leftX+ this.getWidth() )&& (Y  < leftY +this.getHeight()) )
9.        return(true);
10.    else
11.        return false;
12.    }    

 

Now if cursor is within app then I wish to draw a flower at that point.But if I draw flower at the same point as

X = tcur.getScreenX(parentPApplet.width );
Y =tcur.getScreenY(parentPApplet.height);

then it does not draw within child app.Then what should I do to solve this prob??
