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); } }
