Sorry for the slow reply on my part, I'm still travelling around and won't be fully settled until end of January, in any case...
Including time in the CalendarCombo would certainly be interesting, however there would be a few implementation problems undoubtedly. Also, that would take it away from the office look and feel, as the office popup does not do time. I'm not sure how many use it purely for look and feel and how many use it purely for native look or other reasons, but I'm mentioning it just in case. First, the one hurdle that is tricky is the fact that the calendar popup itself is a shell that cannot handle much input without disposing, due to the way the "native" feel of it has been implemented (it was a push to begin with). I have tried my very best quite a few times to make that shell allow me to do native-widget input without throwing various errors due to the fact that it tries to dispose itself. Another reason it is what it is - is because the shell should not steal focus from the parent app, which would look very strange. Perhaps I need to give it another go with a newer SWT version as things always change (the fact that it has two buttons on it still work, but if you look very "quickly" those buttons never depress before the shell disposes and does what the button does). But, if that problem persists, it would be near impossible to add combos and such to the popup shell that allow user input. Windows of course, can do it no problem, but some calls that allow shells to behave that way on windows are not cross platform or at least not in SWT yet. Ok, that said, as far as implementation, I won't have time to do much until end of January myself due to where I am right now, but after that there should be no issues when I'm back on a "normal" schedule. BTW, the writeup is very nice on what each widget does, I want to mention "multi select" dates which is on my todo list for the CalendarCombo, but hasn't been done yet. It shouldn't be too hard to implement I hope.
