Graphichs problem

[memati bas]

Hi everyone,
I do not understand the main and fundamental usage of Graphics class.
For example, when we use this class's instance as a parameter then we can draw smth but where and why ??

Thanks

I think that the main problem is that I also do not understand the main purpose of repaint method.
