How can I change the default look and feel of Jframe? (Not theme of Netbeans)

Question

I want to change the default look and feel of all the jframe forms I\'ll create from here on out instead of having to manually edit every look and feel code of every jframe I cr

Answer 1

First of all take a look to this topic: The Use of Multiple JFrames, Good/Bad Practice?

Note: I am not trying to theme Netbeans itself, I just want the Jframe that I create to have the windows look and feel by default so I don't have to go through the source tab and change Nimbus to Windows for every Jframe I create.

What you want to change is called template: every file you can create through the New File wizard has an associated template. Having said this NetBeans gives the developers the ability to update/create default templates. Go to Tools -> Templates and look for Swing GUI Forms -> JFrame

You have two options here:

1. Open the template in the editor and modify it there.
2. Create a duplicate template and modify this last one.

I'd go with Option 2 just to keep the original template unmodified..

When you edit the template just modify this line (or watherever you want actually):

Finally to create a new "custom" JFrame just find your template in Swing GUI Forms -> MyJFrameTemplate as shown below:

In addition

Reading @Misgevolution's comment below I think there's something to be clarified. This auto-generated main method is there just for test purposes making developers be able to "run" top-level containers. A Java application only needs one main class so this test-only main methods should be deleted when you will deploy your application. As suggested in other answers the L&F should be established only once at the start-up, not in every top-level container.
