gdk event handlers all use a boolean return value; true means "i handled this
event, processing is finished", and false means "i didn't handle this event,
let it bubble on up to whomever else may be interested."  this stuff is
explained in the basic gtk+ tutorial.

so, if you're trapping button-press-event or button-release-event and
returning true, you're not letting the default handlers run and would thus be
breaking the normal click handling.

the callback gives you the column as well as the row, you should be able to
find the cell from there.
