Canvas rendered over JCombobox menu

[JSK]

Hello everyone,
I've been googling and asking for help for a while, but no success.
I've got a Canvas where some stuff is drawn, and a few buttons and comboboxes next to it, lined in a row under the drawing area. When I click on any of the comboboxes, part of the drop-down menu has to be rendered over canvas, but it is always behind it:

Why does this happen, and what can I do?

tnx in advance

Canvas is an AWT, heavyweight component. J–prefix components are Swing, lightweight components. Heavyweight components get rendered on top of/over/above lightweight components and obscure them. Although you can mix them there are some things to be aware of in doing so. For a discussion of this see Mixing heavy and light components.
If you choose to stick with Swing you could replace the Canvas with a JPanel.
