I tried using setOpaque(false); 
我尝试使用setOpaque（false）; but it just makes the background of the JPanel white.. How do i make it not draw the panel at all?. 但它只是让JPanel的背景变白了。我如何让它完全没有绘制面板？

You answered the question yourself. 你自己回答了这个问题。
The JPanel didn't become white, but it showed -- because it became non-opaque -- the JFrame (or other controls) behind it. JPanel并没有变成白色，但它显示 - 因为它变得不透明 - 它背后的JFrame（或其他控件）。
