Place the mouse in the method and either hit F2 and a dialog pops up with
the Javadoc or have the Javadoc view open and the doc will be displayed in
the view.
Also, during code assist (Ctrl+space), if you use the arrow keys to move
through the possible matches, the javaodoc for the selected item will appear
beside the code assist dialog.
However, you should be seeing int x, int y rather than int arg0, int arg1.
I experimented a bit with Eclipse. If I specify the swt jar as an external
jar in the Java Build Path, and do not specify the src or javadoc location,
I get the javadoc as I expected. As soon as I specify the source location,
I do not get the javadoc. This may be a bug in Eclipse. Is your project an
Eclipse plugin or a regular Java project? If it is a regular Java project,
how have you defined your Java build path?

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.)

Thanks again for the support.
My project is a regular, standalone app. It is not a plug in.
We created a new JFace/SWT project and have a JFace Application window.
Isn't it enough to tell the IDE that's what we're doing?
