Hi Ketan,
I've gotten the Recorder to work with Combo boxes. The generated code
looks like this:
bot.comboBox("value_before_selection").setSelection("value_after_selection");
I had to remember a Combo's state when a Combo receives focus, and then
use it when there is a selection on the Combo. This is because we can't
access a Combo's old value after a selection event is fired.
This is, by no means, complete. I need to handle scenarios such as -
what if the combo did not have a value before? what if the combo needs
to be identified some other way, other than by the old value, etc.
I personally like sahi's recorder for web based applications[1]. It
has a very simple, elegant and really smart fall-back mechanism to
deal with identifiers. It uses the 'id' on the HTML element, followed
by the 'name', 'style' and finally just the index of the element to
identify it.
I'm considering something similar, however since swt controls don't
have any such identifiers attached to them, things are a lot trickier.
We'll probably need some form of a strategy to generate alternative
accessors for the same widget and let the user choose what's best.

In my experience using SWTBot, I've seen that a direct qualifier (such
as a label name or a combo's value) is good enough for many cases. But
there are many other cases where such a unique identifier is not readily
available (as you mentioned earlier, trees, lists, etc. fall in this
category). I don't really like using an index to identify a widget.
Seems too fragile to me. But thats just my personal opinion.
Anyway, as a solution for the recorder, I was thinking more along the
lines of letting the user choose what strategy to use. We can have
something like a 'Detailed' mode for the recorder, whereby, whenever a
selection has to be made, a dialog will pop up with multiple options for
the user to choose from. The options might include selection by index,
selection by label, selection by group, etc. - whatever is applicable in
that scenario.
