我有一个Javafx应用程序,它为用户提供了一组工具,每个工具都在一个新的Stage中启动。我尝试了几个小时,但其中一个阶段从不显示垂直滚动条。由于我永远无法看到舞台的下半部分,因此我无法访问水平滚动条。当我在SceneBuilder中尝试舞台时,舞台占用的空间更少(也有些奇怪,但现在我不担心)我看到水平滚动条,但仍然不是垂直滚动条。Javafx stage不显示V-Scrollbar

阶段包含一个嵌套的fxml。主要包含一个带有Treeview的Splitpane。根据树形视图中的用户选择,控制器加载另一个fxml,该fxml始终是一个包含匹配ui的Scrollpane,并将其放在分离面板的另一侧。正是这个Scrollpane导致了这个问题。

这里是启动新的阶段的代码:

protected void showEditor(URL url, Window parent) { 
     FXMLLoader fxmlLoader = new FXMLLoader(url); 
     fxmlLoader.setControllerFactory(springContext::getBean); // lookup the controller from the spring application context 
     try { 
      Parent appNode = fxmlLoader.load(); 
      SystemDependent ctrl = fxmlLoader.getController(); 
      ctrl.setSystemContext(mySelectedSystem); 
      Scene scene = new Scene(appNode); 

      Stage stage = new Stage(); 
      ctrl.setStage(stage); 
      //stage.initOwner(parent); 
      stage.setScene(scene); 

      stage.show(); 

     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
    } 

这是在控制器这使滚动窗格成在将splitPane的右侧的代码:

protected ChangeListener<TreeItem<UserRequirement>> getRequirementSelectionChangeListener() { 
    return new ChangeListener<TreeItem<UserRequirement>>() { 
     @Override 
     public void changed(ObservableValue<? extends TreeItem<UserRequirement>> observable, TreeItem<UserRequirement> oldValue, TreeItem<UserRequirement> newValue) { 

      logger.debug("User selected requirement: " + newValue.getValue().debug()); 

      UserRequirement oldRequirement = newValue.getValue(); 
      reqService.save(oldRequirement); 

      UserRequirement newRequirement = newValue.getValue(); 

      try { 
       if(currentLevel != newRequirement.getLevel()) { 
        currentLevel = newRequirement.getLevel(); 
        RequirementsFactory factory = RequirementFactoryProducer.getRequirementFactory(newRequirement.getLevel()); 
        ScrollPane reqPane = factory.getHierarchyPane(); 
        splitPane.getItems().add(reqPane); 
        ctrl = factory.getHierarchyController(); 
       } 
       ctrl.setSystemContext(getSelectedProduct()); 
       ctrl.setRequirement(newRequirement); 

       stage.sizeToScene(); 
       stage.centerOnScreen(); 
       splitPane.setDividerPosition(0, 0.1); 
      } catch (Exception e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
     } 
    }; 
}

任何帮助,高度赞赏。先谢谢你!

尝试嵌套滚动窗格中的所有UI元素。

你是什么意思?右侧的所有元素都已经在ScrollPane中。将外部BorderPane对话框放置在ScrollPane中会导致一种不同的ui易用性,这会是奇怪的。或者这个测试会提供一个有助于确定根本原因的内容? – Alex

无论如何我都试过了。没有不同。这让我觉得有些更基本的错误。所以我把BorderPane改成了VBox。瞧,我可以看到较低的滚动条。虽然现在好一些,但我还有一个问题:右侧窗格仍然缺少垂直滚动窗格,右侧Splitpane部分的标题的大部分上半部分缺失。 – Alex
