Create a bidirectional binding between this Property and another
Bidirectional bindings exists independently of unidirectional bindings. So it is possible to
add unidirectional binding to a property with bidirectional binding and vice-versa. However, this practice is
It is possible to have multiple bidirectional bindings of one Property.
JavaFX bidirectional binding implementation use weak listeners. This means bidirectional binding does not prevent
properties from being garbage collected.
Remove a bidirectional binding between this Property and another
If no bidirectional binding between the properties exists, calling this
method has no effect.
It is possible to unbind by a call on the second property. This code will work:
