When i create a JButton, a JLabel, any sort of widget or component--i can't resize it. This is true for applications i've designed and been able to do this with in the past, and for brand new ones. I've even made a blank class by extending JPanel. I figured a new version might have caused the issue since i was running on helios, but after upgrading to indigo i still have the same issue.

In any case, i can resize the main JPanel area where things get put, but anything that i put on the panel after that cannot be resized.

Why can't i resize components?

What layout manager are you using?

BTW, it is always a good idea to post an actual test case.

I don't think there's a way to post a test case here - it happens with every class i have. As for layout manager, i'm afraid i'm too new at eclipse to understand the question. Is it something i can change that would effect how things work?

Lots of folks post test cases here...just use copy/paste.

If you don't know what a layout manager is, I would strongly suggest learning a bit more about Swing before using WindowBuilder (it expects you to understand Swing and to know what a layout manager is).

Different layout managers will impose different constraints on your widgets. Some will allow you to set the size while others will calculate the size for you.

Ah. How embarassing. The layout had been set to GroupLayout in the initComponents() functions by default. Thanks for helping me catch that.
