How to create a Dialog in JavaFX?

A Dialog is a graphical element, a window that shows information to the window and receives a response. You can create a dialog by instantiating the javafx.scene.control.Dialog class.

Example

The following Example demonstrates the creation of a Dialog.

import javafx.application.Application; import javafx.geometry.Insets; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.control.ButtonBar.ButtonData; import javafx.scene.control.ButtonType; import javafx.scene.control.Dialog; import javafx.scene.layout.HBox; import javafx.stage.Stage; import javafx.scene.paint.Color; import javafx.scene.text.Font; import javafx.scene.text.FontPosture; import javafx.scene.text.FontWeight; import javafx.scene.text.Text; public class DialogExample extends Application {    @Override    public void start(Stage stage) {       //Creating a dialog       Dialog<String> dialog = new Dialog<String>();       //Setting the title       dialog.setTitle("Dialog");       ButtonType type = new ButtonType("Ok", ButtonData.OK_DONE);       //Setting the content of the dialog       dialog.setContentText("This is a sample dialog");       //Adding buttons to the dialog pane       dialog.getDialogPane().getButtonTypes().add(type);       //Setting the label       Text txt = new Text("Click the button to show the dialog");       Font font = Font.font("verdana", FontWeight.BOLD, FontPosture.REGULAR, 12);       txt.setFont(font);       //Creating a button       Button button = new Button("Show Dialog");       //Showing the dialog on clicking the button       button.setOnAction(e -> {          dialog.showAndWait();       });       //Creating a vbox to hold the button and the label       HBox pane = new HBox(15);       //Setting the space between the nodes of a HBox pane       pane.setPadding(new Insets(50, 150, 50, 60));       pane.getChildren().addAll(txt, button);       //Creating a scene object       Scene scene = new Scene(new Group(pane), 595, 250, Color.BEIGE);       stage.setTitle("Dialog");       stage.setScene(scene);       stage.show();    }    public static void main(String args[]){       launch(args);    } }
