[Tom Eugelink]

My question basically is simple: I need to know the font size (effective height) that is being set through CSS.

But the node serves as the title of a special type of appointment in the agenda control, and I want it to only show the text that fits on the first single line. For this I'm trying to use Text's clipping feature with a rectangle of height "M". My problem is that the font being used is set in CSS.

I also tried listening to boundsInParentProperty and update the height when it gets invalidated, but that does not seem to be triggered.
