This seems to work. It is indeed is a little but late; the font is applied in the \
first pulse and then I apply the clip based that height, so on the second pulse all \
should be okay. I can live with that. Thanks!

@Phil; the question was: I need to know the font size (effective height) that is \
being set through CSS. It makes sense that the font property is set from the CSS, \
could have though of that myself, but didn't. Still learning JFX.

I needed that size in order to clip a multi line text to just a single (the first) \
line. My Agenda control should support the concept of what I call "tasks", which have \
an task date, but no duration. So there is no area where the text is part of (like \
appointments have, naturally clipping this text), but a task is a single moment. \
Maybe task is not the best word, but I haven't found a better one.

Tom
