rectangles in Swing JPanel

[aleplgr]

Hi! I'm trying to draw some filled rectangles in a JPanel, should I define a paintComponent like this?
public void paintComponent( Graphics g) {
super.paintComp onent(g);
g.setColor(Colo r.blue);
g.drawRect(10, 10, 80, 30);
g.drawRoundRect (100, 10, 80, 30, 15, 15);

Or is there any other way to do it? maybe using some Swing component, for example the JTextField is like a rectangle and I could change the background color and if I could set it as a read-only component where the user could not write,that could work as a rectangle..

Using the Graphics object is the normal way of doing it. There are also some g.fillXX methods there.
Is there anything wrong with using the Graphics object?

r035198x is right. Just use the graphics object.

You should describe what you are trying to do. What is your goal?
