本文整理了Java中org.eclipse.swt.widgets.MenuItem.getMenu()方法的一些代码示例，展示了MenuItem.getMenu()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。MenuItem.getMenu()方法的具体详情如下：
包路径：org.eclipse.swt.widgets.MenuItem
类名称：MenuItem
方法名：getMenu

[英]Returns the receiver's cascade menu if it has one or null if it does not. Only CASCADE menu items can have a pull down menu. The sequence of key strokes, button presses and/or button releases that are used to request a pull down menu is platform specific.
[中]如果有，则返回接收器的级联菜单；如果没有，则返回null。只有CASCADE菜单项可以有下拉菜单。用于请求下拉菜单的按键、按钮按下和/或按钮释放顺序是特定于平台的。

   }
  }
  // TODO [rh] find a way to cancel visitor after all menus are done?
  return true;
