I created a component that extends JComponent. In the form designer, when it is resized, I need to perform some actions..in this case increasing the diameter of a meter I am drawing.  What do I do to respond to the resize event inside that component during design time and runtime?

Try overriding Component.validate(). It should be called every time the component is resized. Alternatively, you could always calculate the dimension of the meter based on the current size of the component. That way, you can be sure it's correct, every time the component is painted. (It's been a while since I've done stuff with Swing, though.)

If you're drawing in the JComponent in question, how are you doing that? It should be in paintComponent, in which case, you would know when and how large you need to draw the meter

I had already been trying, but apparently had some bad code.  Also, had to close my the file and recompile..apparently.  It seems to be working now.
