Do I actually call the paintComponent method I make when creating a rectangle in Java?

Question

This is my current RectangleComponent class and I add it to a panel in my main JFrame but it never appears. I thought it wasn\'t drawing so I decided to call the paintComponent

Answer 1

No need to pass JPanel to the constructor of RectangleComponent just to get Graphics, and no need to manually call paintComponent. See Painting in AWT and Swing. Check out this example that demonstrates a custom component that paints a rectangle.
