[lazarus] QT Slots

[Baeseman, Cliff]

That might lead to some interesting things happening. Inside of the toolkit
I do not think I would ever try to connect
two event handlers to the same slot.  Seems to me they did that for
multithreading support?

It's probably OK, but I would be a little concerned about this.  QT slots
are not guaranteed to receive their signals in any particular order, whereas
gtk signals ARE guaranteed to occur in the order in which they were
connected.  Most of the time this won't mean a thing, but every so often it
might have real consequences.

Or are my fears groundless?
