pop-down menu

基本解释

Adding actions to the views' pull-down menu, the common editors' toolbar, and pop-up menus is nearly as straightforward.
向视图的下拉菜单、公共编辑器的工具栏以及弹出菜单添加操作基本上很简单。
Once you have created a menu manager, it can be represented by either a bar menu, a context menu (in other words, a pop-up menu), or a toolbar drop-down menu.
一旦创建了菜单管理器，就可以用菜单栏、上下文菜单（也就是弹出菜单）或工具栏下拉菜单表示它。
A variant of the drop-down menu is a menu that " pops up" when you click (or more frequently, right-click) on an object, even though it has no menu title: a pop-up menu.
右击这些单词会弹出一个可替换的菜单，你可以从中选择。但是你不一定必须改变，你也不会受对话框或者其他愚蠢的模态干扰。
