Old Project, New Version

I reduced my sketch down to just a few swing inputs like one slider, one button, one textfield and gave it another try. I almost have it. I can move the slider and the textfield changes and shows a double. I can also edit the textfield. Edit: Whoops, now I can do both if I use a button to do it. Press the button after entering text and the slider updates.
Edit: Forgot to update the code. And, to use it, enter the text by typing and hitting enter. Then hit the GHA button. Or, move the slider and then hit enter in the textfield or it causes a nullpointer. Also, if you hit GHA and it prints a value in radians, then hit GHA again. Its not perfect, but it is a start.

Here’s the reduced code:
