I think [email protected] is the preferred place for this kind of question, but that's OK.

As far as I can tell from reading WinEvent.c and evtomask.c in libX11/src/, you can't get selection events with XWindowEvent. I've been on a quiet crusade to convince people to quit writing X clients that process events out-of-order anyway. :-) XNextEvent and XPending are OK, but I believe the other event functions should never have been in Xlib. And naturally I think you should be using XCB rather than Xlib for new code, which would mean you'd have to look at events in-order. :-) > ICCCM said “Clients attempting to acquire a selection must set the > time value of the SetSelectionOwner request to the timestamp of the > event triggering the acquisition attempt, not to CurrentTime”.

You're already reading Metacity source, which is probably as good of an example as anything.
