I tried that once, and I think VFE also had the code somewhere (in the resizer class), but it really is tricky. My solution was to preserve the original font size, and get the next font size proportionately , rounding to the nearest integer. The point here was to always compute against the original size as it was at design time, or else the rounding errors would crop up within just a few resizes and the whole thing would become a mess.

I had to do that for a couple of generated webpages (hosted on a VFP form), and had to go through stylesheet rules - not as they are in the stylesheet, but as live objects. Luckily, in a webpage the font size are floating point numbers and the browser will just render them the best it can.Unfortunately, this won't work for Fox controls - you can multiply .fontsize with 1.1, but a 9px will remain a 9px; if you multiply with 1.2, it becomes a 10, no decimals. It's not even rounding, it's taking int().
