Your approach is reasonable. If you look at driver4.cpp you will
see that it checks for heuristicSolution as well as solution.<br>
<br>
If you are using this to check whether to stop you may also wish
to check when event is treeStatus - and then pick up
getBestPossibleObjValue() so that you can look at gap.<br>

<div>I'd like to determine the time a cbc solve takes to pass a
given objective value threshold. My approach is to implement a
custom event handler, and I wanted to double check that this
is reasonable.</div>

and I pass in the custom event handler to the model before
trying to solve it (using CbcMain0/1).</div>

</span>is the right event to check for. I currently have a
instance going that is listening for events (I have a simple
stdout print when it occurs) that has yet to report. Is there
a better way to do this?<br clear="all">
