How do i view decades in javafx DatePicker? - javafx

Question

So if someone is born in 1980 and they want to enter their age through mouse they would have to click on the year arrow 37 times, which is pretty ludicrous.
Is there a way to view the decades in the javafx datepicker so that the user can just choose and option like 1980-1990 and pick a date?
Edit: since no ones answered this yet i'll just post an image for clarity

Answer 1

You could do something like this
public class JavaFxTest extends Application{
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) throws Exception {
Button prevDecade=new Button("Previous Decade");
Button nextDecade=new Button("Next Decade");
DatePicker datePicker=new DatePicker();
Calendar calendar = Calendar.getInstance();
datePicker.setValue(LocalDate.of(calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH)));
prevDecade.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent arg0) {
LocalDate value = datePicker.getValue();
datePicker.setValue(LocalDate.of(value.getYear()-10, value.getMonth(), value.getDayOfMonth()));
datePicker.show();
}
});
nextDecade.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent arg0) {
datePicker.show();
LocalDate value = datePicker.getValue();
datePicker.setValue(LocalDate.of(value.getYear()+10, value.getMonth(), value.getDayOfMonth()));
}
});
HBox hBox=new HBox();
hBox.getChildren().addAll(datePicker, prevDecade, nextDecade);
primaryStage.setScene(new Scene(hBox,500,300));
primaryStage.show();
}
}
But the only problem is that datepicker hides the calendar when the buttons are clicked, so we have to explicitly do datepicker.show(), may be theres a way to fix this, or a better way to approach your problem, this is all I could think of :)
