Hello,

I want to make a dynamic picture in my application.

So I made a subclass of Canvas and made a very nice drawing.

But now I find that my JComboBox insists on opening behind the canvas.

So what should I do to make a drawing that goes behind the drop-down of a JComboBox?

Or JComponent. Canvas is a heavy-weight (AWT) component and the classes which start with J are light-weight components (Swing). You shouldn't usually mix AWT and Swing in your program because it can cause problems like the one you experienced.
