The Menu class takes a circle and "stretches" it. It looks okay until java-script deals with it. It was likely one of the easier codes to accomplish it. Without the "stretching", it would take a lot more image manipulation code to create a rounded button.

ok I also thought about stretching and even two circles at the end of a rectangle on each side but hey I have a little trouble coding for the stretching of the circle, I find the code long, you do not have a small example of stretching code, otherwise I will have to type in all the class menu code thank you

Well, the Button class has a lot of code because it accounts for an abundance of properties that can vary. By fixing ALL values but the text, the code would be minimalized.
