Last article, Create Dialog using Stage, demonstrate how to create our dialog by instancing object from Stage class. Normally, we have a button to close the dialog. In this article, a okButton is implemented to close the dialog.

 @Override

     primaryStage.setTitle("http://java-buddy.blogspot.com/");
     Button btn = new Button();
     btn.setText("Open Dialog");
     btn.setOnAction(new EventHandler<ActionEvent>() {

         @Override
         public void handle(ActionEvent event) {
             final Stage myDialog = new Stage();
             myDialog.initModality(Modality.WINDOW_MODAL);
          
             Button okButton = new Button("CLOSE");
             okButton.setOnAction(new EventHandler<ActionEvent>(){

                 @Override
                 public void handle(ActionEvent arg0) {
                     myDialog.close();
                 }
              
             });
          
             Scene myDialogScene = new Scene(VBoxBuilder.create()
                     .children(new Text("Hello! it's My Dialog."), okButton)
                     .alignment(Pos.CENTER)
                     .padding(new Insets(10))
                     .build());
          
             myDialog.setScene(myDialogScene);
             myDialog.show();
         }
     });
  
     StackPane root = new StackPane();
     root.getChildren().add(btn);
     primaryStage.setScene(new Scene(root, 300, 250));
     primaryStage.show();
 }
}
