Hi, As JavaFX9 has removed impl_reapplyCss() it is impossible for custom controls to deal with a styleable Font-Property.
To correctly implement a Font-Property the code needs to look similar to the one in Labeled#fontProperty. The only possibility I see implementing such a property without providing reapplyCss() to the public is to provide a correct implementation as part of StyleablePropertyFactory.
