JavaFX TextField

Text Field is basically used to get the input from the user in the form of text. javafx.scene.control.TextField represents TextField. It provides various methods to deal with textfields in JavaFX. TextField can be created by instantiating TextField class.

Lets see an example where the user is shown the two text boxes and prompted to fill its user-id and password.

package application;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;
public class TextFieldTest extends Application {

	
public static void main(String[] args) {
launch(args);	
}

@Override
public void start(Stage primaryStage) throws Exception {
	// TODO Auto-generated method stub
	Label user_id=new Label("User ID");
	Label password = new Label("Password");
	TextField tf1=new TextField();
	TextField tf2=new TextField();
	Button b = new Button("Submit");
	GridPane root = new GridPane();
	root.addRow(0, user_id, tf1);
	root.addRow(1, password, tf2);
	root.addRow(2, b);
	Scene scene=new Scene(root,800,200);
	primaryStage.setScene(scene);
	primaryStage.setTitle("Text Field Example");
	primaryStage.show();
}
}

Getting Text field Data

TextField class provides an instance method getText() to retrieve the textfield data. It returns String object which can be used to save the user details in database.

package application;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;
public class TextFieldExample extends Application {

	
public static void main(String[] args) {
launch(args);	
}

@Override
public void start(Stage primaryStage) throws Exception {
	// TODO Auto-generated method stub
	Label user_id=new Label("User ID");
	Label password = new Label("Password");
	TextField tf1=new TextField();
	TextField tf2=new TextField();
	Button b = new Button("Submit");
	b.setOnAction(e->System.out.println("You entered: User_ID: "+tf1.getText()+""+"Password: "+tf2.getText()));
	GridPane root = new GridPane();
	root.addRow(0, user_id, tf1);
	root.addRow(1, password, tf2);
	root.addRow(2, b);
	Scene scene=new Scene(root,300,200);
	primaryStage.setScene(scene);
	primaryStage.setTitle("Text Field Example");
	primaryStage.show();
}
}
