Thread: java graphics2d issue

well the following code is the main code that I use for a drawing program (the drawing panel) that I use all the other buttons are set but I found it redicilous to copy the huge code so I'd only copied the panel code only.
I'm encountring the following issues:
1- when I change the color (for the next shape) all the previous shape colors change! (how can I set the panel that it will set a the color for only the shape that is going to be drawn?)
2- I want the shape to be drawn by pressing only a certain button (the panel is activated with the values without pressing the button how can I change that?)
3- I cannot seem to find a way to make a constant drawing (as in the case of the pen and eraser any code examples for it ?
4- the stroke does not seem to apply to the shapes any changes I should make ?
5- how can I make the line drawing to be on a certain angle?
6- how can I change the angle of the curve given (any examples ?)
7- the thing no matter how much I try to change the background color it doesn't change it... any ideas ?
I would truly appreciate any answers for any of the following questions ...
thank you
