java - 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("Message Here...");
if (rs == ....) {
    // code
}

I want to have a functionality like this using JavaFX SDK. Answers are very much appreciated.

Answer 1

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.");
    }
});
