我正在使用NetBeans IDE在javafx中开发一个项目。我想在同一窗口中打开一个新页面。怎么做 ？我将在下面提供代码。我没有在这里包括导入语句。它在我的实际代码中。
package welcomepage;
public class WelcomePage extends Application {
@Override
public void start(Stage stage) {
// Use a border pane as the root for scene
BorderPane border = new BorderPane();
border.setTop(addVBox());
border.setLeft(addVBox1());
Scene scene = new Scene(border,700,450);
stage.setScene(scene);
stage.setResizable(false);
scene.getStylesheets().add
(WelcomePage.class.getResource("WelcomePage.css").toExternalForm());
stage.show();

最佳答案
您可以将任何窗格保留在“根”节点中
然后通过“下一步”按钮的“操作”，您可以将另一个节点加载到父节点中。
