FILLING an area without using SHAPE class

Question

I am trying to implement the fill operation in a drawing application.
but I am not using the SHAPE class and also I do not know the co-ordinates.
I have just a very faint idea of implementing it, but am not able to path myself out.
If any appropriate method strikes to any of being, please pass on that to me kindly.
Thanks

Answer 1

I think doing the fill operation in the paint() method is a very bad idea... how will yoou keep track of the fill action for the next time the paint() wil be called ?
In fact, you have two solutions:
1) Keep track in an array (or vectors or array list) of every object you create in your drawing tool. For example:
Object 1: Rectangle, bounds=[10,5,100,200], color=blue, fill=false
Object 2: Circle, bounds=[80,45,30,30], color=red, fill=false
Object 3: Shape, bounds=[10,5,50,60], color=green, fill=true
In this case, your paint() method only has to loop thru the objects and do the paintings accordingly.
2) Only keep track of the graphic area. The paint() method first has to recover the previous graphic area, then do the new paint action, and finally backup the graphic area. For example:
   // Call the superclass painting
   super.paintComponent(g);
   // Paint the previous graphic area
   if (oldGraphics != null) g.drawImage(previousGraphics);
   // Paint the new object
   doPaintAction(g);
   // backup the graphic area
   // NOTE: You'll have to find a way to get an image
   // of the graphic area!
   previousGraphics = getGraphicImage(g);Hope this helped,
