• JavaFX Beans
  • In JavaFX, you use one of the JavaFX Bean property classes, than using primitive field types in a class.
  • By convention, getters (read) and setters (write) for a property of a field in a class are declared final. You may not use final ( in simple example like this one)
    
  • Property Interface
    •void bind(ObservableValue<? extends T> observable) :: Unidirectional binding
    • void unbind()
    • void bindBidirectional(Property<T> other)
    • void unbindBidirectional(Property<T> other)
    • boolean isBound()
     
• Emp1
  • Constructor:
    Parameters in Constructor (setting fields)
    Emp1 emp1 = new Emp1("John", "Smith", 2500.25);
  • Java Bean
    import javafx.beans.property.DoubleProperty;
    import javafx.beans.property.SimpleDoubleProperty;
    import javafx.beans.property.SimpleStringProperty;
    import javafx.beans.property.StringProperty;
  • Bean Properties: Bindings
    StringProperty prop1 = new SimpleStringProperty("");
    prop1.bindBidirectional(emp1.firstNameProperty());
  • Bean field's value:
    • String = prop1.get()
    • Double To String::
      prop3.asString().get()
       
• EMP2
  •  (Setting/writing Fields)  No Beans:
    emp2.setfirstName("John");
    emp2.setlastName("Smith");
    emp2.setSalary(2500.55);
  • Constructor:
    EMP2 emp2 = new EMP2();
