如何使JPanel可滚动？当我将它添加到包含面板时,我实现了可滚动界面

tabbedPane.add("Editor", new JScrollPane(storeyEditor = new MNScrollablePanel()));

什么都行不通

码:

public class MNScrollablePanel extends JPanel implements Scrollable {

    public Dimension getPreferredScrollableViewportSize() {
        return getPreferredSize();
    }

    public int getScrollableBlockIncrement(Rectangle visibleRect, int orientation, int direction) {
        return 10;
    }

    public boolean getScrollableTracksViewportHeight() {
        return false;
    }

    public boolean getScrollableTracksViewportWidth() {
        return false;
    }

    public int getScrollableUnitIncrement(Rectangle visibleRect, int orientation, int direction) {
        return 10;
    }
}

我有以下代码片段，它有点工作：

launchTask :: (DeviceRepo m) => TaskSpec -> m (Maybe Task)
launchTask taskSpec@TaskSpec { taskSpecImage = image
                             , taskSpecRequirement = requirement
                             } = do
  mayDevice <- getDeviceMatchingRequirement requirement
  case mayDevice of
    Nothing -> return Nothing
    Just device -> do
      mayContainer <- createContainer device requirement
      case mayContainer of
        Nothing -> return Nothing
        Just container ->
          return $
          Just
            Task
              { taskName = pack image
              , taskStatus = TaskStatusRunning
              , taskSpec = taskSpec
              , taskContainerId = containerId container
              }

但是，我觉得这不是很地道。堆叠主要计算（来自 DeviceRepo m）和可能的 …

我想将一个字符串(char*)解析为C中的tm结构.是否有任何内置函数可以做到这一点？

我指的是C99标准中的ANSI C.
