Clickable button in jtable header

Question

Here is a modification of camickr code to make buttons clickable in the jtable cells. The question is how to modify it to make them clickable in the table headers. It looks like there is quite a different behavior in cells and headers (naturally it probably should be this way). More specifically, I guess my question is how do you modify MyColHeaderRenderer class in the code below. Btw, this is also an example I've mentioned in one of the previous posts when a component responds to a press mouse event but not click event when first pressed.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.table.*;

Answer 1

draw a shape and ensure it is selected
in the Inspector > hyperlink > enable as hyperlink > click slide button and enter the slide number
place the object in slide 2 and create a dissolve to automatically build on entry for the object
