Number of pending events
Message 1 in thread
Fellow Qt users,
is there any way to get the number of pending (custom) events in the
event queue? I am developing a real time application using Qt. When
data arrives (in a separate thread), it's posted on the event queue as
custom QEvent objects. I would like to be able to monitor the number
of pending events to determine if data is being received faster than
it can be processed and displayed. Is there any quick way to do this?
Rgds,
Jarle

None that I am aware of.

Bump some variable when an event is put into the queue and decrement
it when it was handled/removed from the queue.

If you come up with a nice way of doing this, please post it to the
list. I'm certainly interested in this topic as well.
Thanks,
