Question

我正在尝试使用Scene Builder实现相同的界面。但由于某种原因，CSS没有加载。这就是我应该得到的！这就是我得到的！

Parent root;

    try {

    root = FXMLLoader.load(getClass().getResource("/path../path../TutorControlPanel.fxml"));

    Stage stage = new Stage();

    stage.setTitle("Tutor Control Panel");

    stage.setScene(new Scene(root, 950, 750));

    stage.show();

         } catch (IOException ex) {
             Logger.getLogger(LoginController.class.getName()).log(Level.SEVERE, null, ex);
                       }
                } else {
                      System.out.println("user not found");

                        }

                        }

               } catch (SQLException ex) {
                 Logger.getLogger(LoginController.class.getName()).log(Level.SEVERE, null, ex);                     }

Answer 1

我必须进行2次更改才能获得预期的结果

1.首先，将所有图像放入Style.css

的文件夹中

2.其次，添加以下代码行：

String css = this.getClass（）。getResource（＆＃34; Style.css＆＃34;）。toExternalForm（）; 。scene.getStylesheets（）添加（CSS）;

     try {

    Parent root=FXMLLoader.load(getClass().getResource("/eLearning/UserInterface/TutorControlPanel.fxml"));
    Scene scene = new Scene(root);

      String css = this.getClass().getResource("Style.css").toExternalForm();
                        scene.getStylesheets().add(css);
                        Stage stage = new Stage();

                        stage.setTitle("Tutor Control Panel");

                        stage.setScene(scene);
                        stage.show();

                    } catch (IOException ex) {
                        Logger.getLogger(LoginController.class.getName()).log(Level.SEVERE, null, ex);
                    }
                } else {
                    System.out.println("user not found");

                }

            }

        } catch (SQLException ex) {
            Logger.getLogger(LoginController.class.getName()).log(Level.SEVERE, null, ex);
        }
