Creating a Calendar using javafx - java

I am a little stumped on how to get started on this project I have in front of me. I simply need to create a calendar on a javafx stage for the current date with two simple next / prior buttons to go between months.
So far I have just created the minimum, a blank stage to appear.
public class Calendar extends Application{
#Override
public void start(Stage primaryStage) throws Exception {
primaryStage.setTitle("Java Calendar");
Pane base = new Pane();
Scene scene = new Scene(base, 500, 300);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args){
Application.launch(args);
}
}
I had noticed under java documentation that there is a calendar class under java.util, however the documentation was rather confusing to me on how to implement it. Basically I want to ask, what is the best way to approach this? Would you be able to show me through the basics of how this or another Calendar class works? Or would I be best off using a grid pane, and switch between what scene is shown on the stage when I click the next or prior button?
Thank you so much for your time.

Try This
import java.time.LocalDate;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.DatePicker;
import javafx.scene.control.Label;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class Main extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage stage) {
VBox vbox = new VBox(20);
Scene scene = new Scene(vbox, 400, 400);
stage.setScene(scene);
DatePicker startDatePicker = new DatePicker();
DatePicker endDatePicker = new DatePicker();
startDatePicker.setValue(LocalDate.now());
endDatePicker.setValue(startDatePicker.getValue().plusDays(1));
vbox.getChildren().add(new Label("Start Date:"));
vbox.getChildren().add(startDatePicker);
vbox.getChildren().add(new Label("End Date:"));
vbox.getChildren().add(endDatePicker);
stage.show();
}
}

How to display some values of javafx combo box before any click on it?

I use a combo that works nice. The only thing i would like to add is to diplay some items(~10) of this box by default at start . I tried to find this property but a hell to find this among all methods.
If somebody knows how to to that
I have the same question for Menubutton
Thanks
Just call show() on the ComboBox. Here is an example:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.ComboBox;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class ComboTest extends Application {
#Override
public void start(Stage stage) {
ComboBox<String> combo = new ComboBox<>();
for (int i = 1 ; i <= 20 ; i++) combo.getItems().add("Item "+i);
BorderPane root = new BorderPane();
root.setTop(combo);
Scene scene = new Scene(root, 650, 400);
stage.setScene(scene);
stage.show();
combo.show();
}
public static void main(String[] args) {
Application.launch(args);
}
}
The same thing works for MenuButton.

Let Window scroll down in JavaFX

So I am trying to learn Java now that I know JavaScript and PHP. I am working in Netbeans with JavaFX and I am trying to create a program that creates 5 buttons. (This is modifying the code that comes with Netbeans when creating a new JavaFX Application.) If I change the y-argument of the scene to be less than the y of all of the buttons, it will not display the remaining buttons and it will not be able scroll down. This is what I have so far. How do I enable it to scroll down so all buttons can be seen? I know that I can just change the scene back to its old height but I want to learn about scrolling with JavaFX.
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;
import javax.swing.JScrollPane;
public class JavaFXApplication1 extends Application {
#Override
public void start(Stage primaryStage) {
GridPane root = new GridPane();
Button[] btn=new Button[5];
for(int i=0;i<5;i++){
btn[i] = new Button();
btn[i].setText(i+"");
GridPane.setRowIndex(btn[i],i);
root.getChildren().addAll(btn[i]);
btn[i].setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
System.out.println("This is a button");
}
});
}
Scene scene = new Scene(root, 300, 50);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Using ScrollPane to set root as:
ScrollPane sp = new ScrollPane();
sp.setContent(root);
Scene scene = new Scene(sp, 300, 50);

NotificationPane doesn't show up in Scene

I would like to display a NotificationPane after certain user actions. My application has multiple scenes and the NotificationPane should be showed up in the currently active scene.
The whole thing works with Notification, it pops up when I need it.
But I can't figure out how to make this work for NotificationPane.
Steps I made so far:
I tryed to put NotificationPane directly to my scene and call
show() - it works.
Now the Idea is to get the current pane by calling
stage.getScene().getRoot(), wrap it to NotificationPane and then call
show() - it doesn't work and I have no idea why.
((BorderPane) pane).setCenter(new Label("TEST")); this line is replacing buttons with text label, so stage.getScene().getRoot() is returning the right object
I made a simple program to test the behaviour. One button to call NotificationPane.
Any suggestions?
Here is my test program:
package application;
import org.controlsfx.control.NotificationPane;
import javafx.application.Application;
import javafx.geometry.Pos;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class Main extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) {
Button notificationPaneButton = new Button("NotificationPane");
notificationPaneButton.setOnAction(e -> showNotificationPane(primaryStage, "Notification text"));
VBox vbox = new VBox(5);
vbox.setAlignment(Pos.CENTER);
vbox.getChildren().addAll(notificationPaneButton);
BorderPane borderPane = new BorderPane();
borderPane.setCenter(vbox);
primaryStage.setTitle("Notifications test");
primaryStage.setScene(new Scene(borderPane, 300, 200));
primaryStage.show();
}
public void showNotificationPane(Stage stage, String message) {
Parent pane = stage.getScene().getRoot();
// ((BorderPane) pane).setCenter(new Label("TEST"));
NotificationPane notificationPane = new NotificationPane(pane);
notificationPane.setText(message);
if (notificationPane.showingProperty().get()) {
notificationPane.hide();
System.err.println("hide");
} else {
notificationPane.show();
System.err.println("show");
}
}
}
Ok, I see the problem now. Wrapping current pane is not enough, I also have to add the NotificationPane to the scene. Right?
Anyway my current solution is following:
get current scene
get current pane
wrap pane
replace current scene with the new one
To avoid wrapping NotificationPane multiple times I check if current pane is already a NotificationPane and then call show().
public void showNotificationPane(Stage stage) {
Scene scene = stage.getScene();
Parent pane = scene.getRoot();
if (!(pane instanceof NotificationPane)){
NotificationPane notificationPane = new NotificationPane(pane);
scene = new Scene(notificationPane, scene.getWidth(), scene.getHeight());
stage.setScene(scene);
notificationPane.show();
} else {
((NotificationPane)pane).show();
}
}

How to get narrow progres bar in JavaFX?

As the title says, I need to make a thin progress bar. I used this:
progressBar.setMaxHeight(0.1);
progressBar.setPrefHeight(0.1);
but that doesn't work. Does anyone have an idea?
You'll have to mess around with the styling to get it any smaller. I really recommend taking a look a the caspian.css that's included with Javafx - that's the default style sheet. It helps a lot when trying to override the look and feel of the default skins. Here's an example I put together that shows how it can be done:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.ProgressBar;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class ProgressBarTest extends Application {
public static void main(String[] args) { launch(args); }
#Override
public void start(final Stage stage) throws Exception {
//All the controls are added here
VBox box = new VBox();
box.getStylesheets().add("test.css");
ProgressBar pb = new ProgressBar(50);
box.getChildren().add(pb);
//Setting up your scene
Scene scene = new Scene(box);
stage.setScene(scene);
stage.show();
}
}
And here's the test.css I loaded up:
.progress-bar .bar {-fx-padding:1px; -fx-background-insets:0;}
And here is the output of the test app:

MiGLayout sizing not working properly in JavaFX

Here's my snippet:
package javafxdemo;
import org.tbee.javafx.scene.layout.MigPane;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.stage.Stage;
public class FXDemo extends Application {
#Override
public void start (Stage stage) throws Exception {
MigPane root = new MigPane();
Scene scene = new Scene(root);
Button b = new Button("Hello");
root.getChildren().add(b);
stage.setScene(scene);
stage.setTitle("FX");
stage.show();
}
public static void main (String[] args) {
launch (args);
}
}
When running the gui doesn't show properly: the frame size is smaller than the button. Why does it happens? In HBox Layout when setting the scene it is automatically resized, so why with MiGLayout it doesn't work?
I'm using MigLayout 4.3
So, I filed an issue and later found out a workaround for this:
just add stage.sizeToScene() after stage.show().
