title: show hide panel in javafx using fxml
body: <p>I have made the GUI of my javafx application in scenebuilder. I have correctly made the settings of placing the fxml and my application works perfect. Now I want to add action events to buttons and when a button is clicked, a panel should be shown and when other button is clicked, the other panel should be shown. Please help me. And remember that I am building my interface using scenebuilder i.e using fxml for my interface.</p>
