Question

I am developing a small desktop application in Netbeans. The application is complete and working fine. A small description of application is as follow:

The application is basically an object manager, where user add new object, remove old objects and connect object with each other. What i did is that i simply add 3 panel and change its type to titled border. One for Add object one for remove and one for connect.

Status:

Every thing is working fine as expected.

What Left:

In order to make UI more appealing i added a new panel at the end and called it “Object Viewer”. I am planing to visualize the steps which user performs e.g

1. If user add an object then i that pannel i will daraw a little
   circle and fill it with green color

2. Similarly if user remove some object then again i will draw another
   cricle and fill that with red

3. And when user connects two object then i will draw two circle and
   connect them with a dotted line

This is my first java application, i only want to know how do i acheive this task. Some links or experience are highly appreciated

Answer 1

You can either do that manually with Java 2D, which I don’t recommend, or, since you are using Netbeans (and I assume the Netbeans Platform, but this is not required), I would strongly suggest looking at the Netbeans Visual Library. It can do exactly what you want.
