I was finally able to figure out the problem by looking at the splitter.cpp
test application. At the end of the constructor there is a rather
inconspicuous comment and invocation:

// Make a tool tip
new FXToolTip(getApp(), 0);

This was the missing instruction that I needed to add in order to "opt-in"
to getting tooltips in my FXTreeList widget.
