Notice that in the main program CustomComponent class, we did not load any FXML files. We simply instantiated
ProdId , and proceed to use it as if it is a native JavaFX node. The FXML file simply put two TextField s and a Label
in an HBox type fx:root . No fx:controller is set because we want to set it in the constructor of the ProdId class. In
addition to the two injected TextField s, we have another StringProperty field called prodId , for which we defined a
getter getProdId() , a setter setProdId() , and a property getter prodIdProperty() .
private StringProperty prodId = new SimpleStringProperty();
public String getProdId() {
return prodId.get();
}
public StringProperty prodIdProperty() {
return prodId;
}
