Hi there,
I am doing Paint application using Dessign Pattern Abstract Factory. So far I have done canvas, stroke, and I could write on it. The problem is I want to create menu in which they will be Rectangle, Circle and so on objects but I do not know how to implement them, so when I click on the bar in the menu, and point somewhere stroke to draw me Rectangle, Circle or anything else. Anyway here is my code I have done, and main problem lays in how to implement that when I click on the bar it gets me a rectangle, circle ....
Here is the code :

I am doing Paint application using Dessign Pattern Abstract Factory. So far I have done canvas, stroke, and I could write on it. The problem is I want to create menu in which they will be Rectangle, Circle and so on objects but I do not know how to implement them, so when I click on the bar in the menu, and point somewhere stroke to draw me Rectangle, Circle or anything else. Anyway here is my code I have done, and main problem lays in how to implement that when I click on the bar it gets me a rectangle, circle ....
Here is the code :
interface ShapesFactory { public ShapeInterface createShape(); }
public class RectangleFactory implements ShapesFactory { public RectangleFactory() { } public ShapeInterface createShape() { return (ShapeInterface) new Rectangle(); } }
public interface ShapeInterface { public void createShape(Graphics2D g, int x1, int y1); }
public class Rectangle implements ShapeInterface{ public void createShape(Graphics2D g, int x1, int y1) { GeneralPath gp = new GeneralPath(); gp.moveTo(x1, y1); gp.lineTo(x1, 20+y1); gp.lineTo(30+x1, 20+y1); gp.lineTo(30+x1, y1); gp.lineTo(x1, y1); gp.closePath(); g.fill(gp); }Now problem is I do not know how to implement that when I click on the rectangle bar it switches to the rectangle, and I can draw with my stroke rectangle anywhere on the canvas. Please, help me.
