Java2D Clearing a Frame

[xddxogm3]

Please do not flame me for bringing up java on our board, but I have a question that has been sitting for a long time on the Java Technologies Board, and has not been answered.

I have drawn with the graphics object on a jframe.
I want to delete the drawings on the frame and start over new.
Can I delete all drawings on that JFrame?
Possibly a method call that would erase all drawings. I'm wanting to reuse the frame for an additional drawing after it has been cleared.

Thank you for any help you provide.

A JFrame is a container widget that you add components to. Im not sure exactly what your drawing to but to remove everything from a JFrame use this...

myFrame.getContentPane().removeAll();

I believe you can simple do a fillRect() with a specified colour to clear the JFrame's contents.

Also, I think it is widely accepted that drawing directly on a JFrame is bad form. You should do your drawing on a derived JPanel class, and use it as the JFrame's content pane (using setContentPane()).

yeah, but your method just covers whats underneath...Perspective's method is better.

removeAll() just removes components from the JFrame.

It doesn't actually redraw the JFrame.

i searched google and found the following bit of code in a post that was made about 2 years ago. surprisingly it was not purged off the newsgroup it was located on. chalk another win for google. tell me what you think. yes it is a good way to do it, or no it isn't and why.

Graphics x = getGraphics();
x.clearRect(0,0,400,400);	 //400 X 400 (frame size)

again what i'm trying to do is erase the frame i'm drawing using a graphics object and with graphic methods (drawOval() & drawLine()). again thank you for the help. on the java board, i didn't get much assistance at all.

btw the following doesn't work in my code for some reason.

myFrame.getContentPane().removeAll();

i'm extending jframe and using the inharitence. i executed the code with

getContentPane().removeAll();

and nothing happened

another fu question

Also, I think it is widely accepted that drawing directly on a JFrame is bad form. You should do your drawing on a derived JPanel class, and use it as the JFrame's content pane (using setContentPane()).

why is it bad form? can you draw to a content pane similar like to a jframe?
i have attached my code as .txt for comments on how to fix the bad form.
please forgive the horrible commenting. I haven't finished the project yet.
