Netbeans’ GUI builder is great. It’s one of the essential features that made me drop eclipse.
But designing accurate GUIs can be a pain in the arse. Especially, when you use the GUI builder with a certain preview Look and Feel (e.g. GTK+) but you application later runs with a completely different L’n’F (e.g. Nimbus). It’s almost certain, that your design will look rather ugly. Unless you want to design your GUI manually (which isn’t a bad idea, btw.), you have to make sure, your design preview and application match.
$ netbeans --laf Nimbus
If you want to start Netbeans in Nimbus-mode per default, just add
--laf Nimbus to
If the file doesn’t yet exists
mkdir -p ~/.netbeans/6.5/etc/ echo netbeans_default_options=\"--laf Nimbus\" >> ~/.netbeans/6.5/etc/netbeans.conf
