Javafx combobox not updating dropdown size upon change on realtime?

Question

I am using Javafx v8.0.25-b18.

Answer 1

Try this:

box.hide(); //before you set new visibleRowCount value
box.setVisibleRowCount(rows); // set new visibleRowCount value
box.show(); //after you set new visibleRowCount value

It's works for me with editable comboBox and I think it will work in your case.
