Slider not working

Hello,

I am writing an applet that will display me four different polygons using four buttons.Also, i have a slider that is used to change the sizes of the displayed shape.Using this slider, when for example a rectangle is displayed, moving it ahead will increase it's size and vice versa.

I wrote the code, but i cannot increase/decrease the size using slider.I am sure the slider can listen to the event.But, i am not sure where it's going wrong.Please help.

Note: I have four classes for the four polygons to initialize the co-ordinate points.

So what is the maximum value on your Slider? Why are you dividing it by 100?

The maximum value is 100 , minimum is 0 and middle is 50.I got this formula from a book, (2^50 -1), for calculating the value when slider changes its position.

. . . and what is the result when you divide the slide position by 100?

72 posts and you still don't know better than to post oodles of commented-out code and excess vertical whitespace? Honestly, making your code and posts more readable is in your best interests.
