JavaFX 2.1 MessageBox

Question

Good day!
I am developing a program using JavaFX SDK. I wanted to have a message box like in C#:

DialogResult rs = MessageBox.showDialog(\"Mess         


        

Answer 1

This is a very simple example : Alert alert = new Alert(AlertType.CONFIRMATION, "Are you sure you want to proceed?");

Answer 2

Here is another simple alternative: https://sites.google.com/site/martinbaeumer/programming/open-source/fxmessagebox

Surprising that there is still no standard message box available in JavaFX 2.2

Answer 3

Use the namespace:

import javafx.scene.control.Alert;

Calling from main thread:

public void showAlert() { 
    Alert alert = new Alert(Alert.AlertType.INFORMATION);
    alert.setTitle("Message Here...");
    alert.setHeaderText("Look, an Information Dialog");
    alert.setContentText("I have a great message for you!");
    alert.showAndWait();
}

Calling from not main thread:

public void showAlert() {
    Platform.runLater(new Runnable() {
      public void run() {
          Alert alert = new Alert(Alert.AlertType.INFORMATION);
          alert.setTitle("Message Here...");
          alert.setHeaderText("Look, an Information Dialog");
          alert.setContentText("I have a great message for you!");
          alert.showAndWait();
      }
    });
}

Answer 4

https://docs.oracle.com/javase/8/javafx/api/javafx/scene/control/Alert.html

The Alert class subclasses the Dialog class, and provides support for a number of pre-built dialog types that can be easily shown to users to prompt for a response.

So the code looks something like

Alert alert = new Alert(AlertType.INFORMATION);
alert.setTitle("Message Here...");
alert.setHeaderText("Look, an Information Dialog");
alert.setContentText("I have a great message for you!");
alert.showAndWait().ifPresent(rs -> {
    if (rs == ButtonType.OK) {
        System.out.println("Pressed OK.");
    }
});

Answer 5

MessageBox on JavaFX 2.2 by OSS is here

I think it will help you.

MessageBox.show(primaryStage,
    "Message Body",
    "Message Title", 
    MessageBox.ICON_INFORMATION | MessageBox.OK | MessageBox.CANCEL);

At the moment I use this library for showing Dialogs. Maybe it can be of use for you:
