Excuse me for long listing of code in attached file. I need it to work.

There are Label, TextField and Text in the HBox.

And I want to see their baselines in different situations. Situation is changed using "LeftArrow" pressing. Situation is about alignment of content in HBox.

To account baseline I need getMinY.

Content of HBox changes it position for each situation, but for all cases I see the same output in line 82 of code:
"Min Ys: 0.0 -32.373046875 0.0"

That is wrong.
