Java JSpinner Looks Ugly

GUI

i am trying to use JSpinner but as you can see from the attached image that it looks bad.

i am on windows 7. i was wondering if anyone knows how to make it look good?

just for clarity. bad means the edges dont 开发者_开发技巧line up and good means the spin control edges line up correctly.

thank you.

EDIT: maybe there is no cure for this? because i checked site and all their examples look like this!

You can try a different Look & Feel, although it looks like right now you are going for the platform look and feel. Some alternatives (that won't, as far as I know, mimic the Windows 7 look at feel) are Substance and Nimbus.
