FXML to open a new scene via button

Question

I am using Scene Builder to create a JavaFX GUI application. I am trying to implement something like this, using FXML:

reportButton = new Button("Report");
reportButton.setOnAction(e -> ReportPage.display());

but I can't figure it out how to do that using the controller page. Can someone please tell me how do I do that? Thank you

Here is how could show a new stage. Add this code in your on action function
(you can add that function with scene builder in code : On action property)

@FXML
private void reportButtonHandler(ActionEvent event) {
    FXMLLoader fxmlLoader = new 
        FXMLLoader(getClass().getResource("pathtofxml/ReportPage.fxml"));
    Parent root1 = (Parent) fxmlLoader.load();
    Stage stage = new Stage();
    //set what you want on your stage
    stage.initModality(Modality.APPLICATION_MODAL);
    stage.setTitle("Report Page");
    stage.setScene(new Scene(root1));
    stage.setResizable(false);
    stage.show();
}
