JCombobox dropdown visibility issue?

Question

I have a root panel (2 rows, 1 column) which has panel P and a label L in it. P has a JComboBox B in it. Whenever I click on B, the resulting dropdown shows-up behind L. How do I fix this? I played around with all sorts of setComponentZOrder() but I could not fix this. What should I do?

I never see that (except `OverlayLayout`), which `LayoutManager` is used for ? or by mixing `ATW Components` with `Swing JComponents` — mKorbel, Jul 19 '11 at 18:50
You were right I had mixed in a awt.Label instead of using swing.JLabel. Switching to latter, fixed my problem. Thank you. — pathikrit, Jul 19 '11 at 18:55
@mKorbel: This happens even when combining `JFrame.getRootPane()` with Swing components as I've just experienced. Btw., I can see you're even more active than you used to be on "builder". — maaartinus, Jan 21 '14 at 02:58

Don't mix heavyweight components (e.g. Label) with lightweight components (e.g. JLabel).

If you use Swing always use lightweight components starting with a J.
