Hot Tracking for TDBGrid

Delphi’s TDBGrid displays and manipulates records from a dataset in a tabular grid.
Contrary to what most novice developers think, the DBGrid component allows various customizations.
Changing the color of a specific cell or a column or even a row is not complicated at all.
What most are not aware of, is that you can even implement the OnMouseHover (hot tracking) behavior to change the display (color, font, etc.) of the DBGRid’s (data) row underneath the mouse - *not* the currently selected row - thus making it look like today’s web driven interfaces.

I’m sure you’ve seen this behavior many times - many tables on the Web change the background color of their rows as mouse hovers over them.
