Dialog with CLOSE button

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.

Button btn = new Button();
btn.setText("Open Dialog");
btn.setOnAction(new EventHandler<ActionEvent>() {

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();
}
}
