Hi Veronika. I briefly tried the F2 key, but it didn't show anything
beyond what code assist shows (for example, it tells me that there are two
int arg's, which I already knew).
The advice about the build path is something I will need to explore, but I
wanted to get back quickly and say thanks for the help.
(My comment to SWT/Eclipse developers is: why isn't this easy and
automatic? Yes, it's nice to have things flexible and reconfiguarable,
but imagine if this happened to you when you bought a car? You get a bag
full of parts, all ready for you to assemble, anyway you please, when all
you want to do is drive the car somewhere.)
