I actually had that same idea at one point, but it didn't work.

After a little more reading, it seems like the difference between 'heavyweight' and 'lightweight' objects is how they tie into the windowing system.  AWT seems to do more things directly with the native windowing system whereas Swing doesn't hook as deeply into the native windowing system.

This is what makes Swing objects look significantly better and take up less resources regardless of the platform the code is running on.

I'm not really sure what is causing HexMap to be considered 'heavyweight'. As far as I can tell, it's comprised of only lightweight objects.

Ahh... I'm pretty sure I know what that is.

In the paint() method for each GUIHex, you'll notice a call to g2.setClip(hexagon)

This sets the clipping boundary for each hex to be the size and dimensions of the hexagon. This is probably cutting out the borders on the hexes.

However, the reason we need to setClip() is because otherwise the clickable area for each hexagon would be a bunch of overlapping rectangles that cause problems for detecting which hex a click triggers.
