How can I achieve WYSIWYG in NetBeans GUI Builder?

I've spent many fruitless hours trying to create what I consider to be a very simple GUI. One thing that makes it simple is that I don't even expect it to be resizeable. I want it to display just the way I've laid it out. Simple as that.

There's a JFra开发者_JAVA技巧me containing two Jpanels of equal width, one above the other. I've got the JPanels behaving themselves finally, and I can slide them around without their enclosed components mysteriously shifting.

But I can't for the life of me get the JFrame to nicely enclose the JPanels. I'm attaching a screen shot showing the layout and the inspector

, and another showing how it previews

(Notice that it's chopping off the bottom edge.)

Is there any way to work in a "WYSIWYG mode" in the GUI builder? I don't care about (in fact, I dread) resizeability, at all at this point. I would have thought Absolute Layout would be the right choice for this, but there's still something wrong. (I need an elementary solution, folks -- please don't suggest GridBagLayout!! ;)

EDIT: By restoring some defaults, mainly for MaximumSize, to the JFrame, I got rid of the clipping problem. The right edge was still off by one pixel, and I managed to find which of five (five!) width properties was controlling that. (bounds, max size, min size, preferred size, and width - changing min size fixed that.)

I've already found that you can't completely avoid tweaking properties (e.g. to override "snapping" and achieve pixel-precise positioning). I clearly made trouble for myself at some point by playing with some properties I shouldn't have. The question remains: for non-resizable, WYSIWYG GUI design, is Absolute Layout a reliable choice; and, what properties should I avoid editing?

Is the JFrame showing any better when you actually run than preview? I think this is an OS X specific NB behavior. I did not see this in Win32. For now, you may try adding a JLabel ( spaces as the text content) at the bottom to make sure that space is drawn when the actual JFrame runs.
