I have a Jpanel right beside a Canvas. The Jpanel contains some JButtons and JComboBoxes with tool tips. The problem is that a long tool tips string will be hidden under the Canvas. A similar thing happens if I place the JPanel above the Canvas, when the JComboBox is opened and "droped down" then most of the combobox box is hidden under the Canvas. Can I set a higher Z-order (or similar) on the Jpanel?
