Continue your JavaFX Components learning via this tutorial.
Example 1: Textfield
Let us look at the code
Step 1: Create Project
- Open your favorite Java IDE.
- In the menu go to
File --> Create New Project
.
Step 2: Dependencies
No dependencies are needed for this project.
Step 3: Write Code
Our code will comprise the following java files:
TextFieldExample.java
- In your editor or IDE, create a file known as
TextFieldExample.java
. - Then add the following code:
(a). TextFieldExample.java
Our class will do with some imports. Let's go ahead and add them:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.scene.layout.Pane;
import javafx.scene.text.Font;
import javafx.scene.text.FontWeight;
import javafx.stage.Stage;
Extend the class
as shown below:
public class TextFieldExample extends Application {
Our class
will have the following methods:
void main(String[] args)
void start(Stage primaryStage)
The starting point of our Java app will be main method which we create as follows:
public static void main(String[] args) {
In this particular class
we will be overriding our void start(Stage primaryStage)
method.
Prepend the code>@Override</code modifier to your method. Then add implementation code as follows:
@Override
public void start(Stage primaryStage) {
TextField textField = new TextField();
textField.setFont(Font.font("Arial", FontWeight.BOLD, 36));
textField.setText("This text is visible");
String text = textField.getText();
System.out.println(text);
Scene scene = new Scene(new Pane(textField), 500, 250);
primaryStage.setScene(scene);
primaryStage.show();
}
Here is the full code:
package com.jenkov.javafx.textfield;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.scene.layout.Pane;
import javafx.scene.text.Font;
import javafx.scene.text.FontWeight;
import javafx.stage.Stage;
public class TextFieldExample extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
TextField textField = new TextField();
textField.setFont(Font.font("Arial", FontWeight.BOLD, 36));
textField.setText("This text is visible");
String text = textField.getText();
System.out.println(text);
Scene scene = new Scene(new Pane(textField), 500, 250);
primaryStage.setScene(scene);
primaryStage.show();
}
}
