Thanks much, Dave.
I've setup a test case based on your code, and what's happening (at
least for me) is that MyGridHit is only getting activated when I click
on a cell in the grid, and then the tooltip is displayed when I hover
over that and other cells in the column, but to change the tooltip I
have to click a different cell. Is that your design? I was hoping to be
able to change the tooltip merely by hovering the mouse over a cell
(without 1st clicking anywhere). That was the initial idea anyway, but
now I'm beginning to think that this approach may be okay.
You're right, it is fun! I'm just feeling a little under the gun to get
a lot of stuff done, so can't take too much time to stop and appreciate
these wonders :)
