how to draw ellipse over the jpanel

Question

I have three classes: CanvasPanel, Drawline and DrawRectangle.

• CanvasPanel: This is for handling all mouse event listener.
• Drawline: This is for drawing line on CanvasPanel.
• DrawRectangle: This is for drawing rectangle on CanvasPanel.

All three class are extending JPanel class.

Drag and drop of all component is going fine. But the problem is when I drag the line over the rectangle then line has been gone behind the rectangle. Can you give me the solution or give me some example, so I can understand how this is happening.

thanks

Make the components transparent by calling setOpaque(false).
