Setting a renderer on JComboBox

Thu, 01 Sep 2011 00:34:38 +0200

When setting a custom renderer to a JComboBox, the usual way is to extend a DefaultListCellRenderer and override the getListCellRendererComponent() method. However, this may lead to ugly comboboxes on some Look and Feels. As you can see on the top combobox, it is rendered considerably smaller and with the letters sticked to the left border, just by using a DefaultListCellRenderer. The Look and Feel seems to use a special renderer class for proper rendering, as it is shown in the combobox below.
