## Detailed Description
该QUndoGroup类是一组[QUndoStack](qundostack.html)对象。
对于Qt的撤消框架的概述，请参阅[overview](index.htm)。
一个应用程序通常有多个撤消堆栈，每一个打开的文档。与此同时，应用程序通常有一个撤消操作和一个重做动作，这会触发撤消或重做的活动文档。
QUndoGroup是一组[QUndoStack](qundostack.html)物，其中之一可以是活动的。它有一个[undo](qundogroup.html#undo)（）和[redo](qundogroup.html#redo)（）槽，它调用[QUndoStack.undo](qundostack.html#undo)（）和[QUndoStack.redo](qundostack.html#redo)（ ）为活动堆栈。它还具有功能[createUndoAction](qundogroup.html#createUndoAction)（）和[createRedoAction](qundogroup.html#createRedoAction)（ ） 。这些函数返回的动作相同的行为方式的那些返回[QUndoStack.createUndoAction](qundostack.html#createUndoAction)（）和[QUndoStack.createRedoAction](qundostack.html#createRedoAction)活动堆栈的（） 。
堆栈被添加到一个组[addStack](qundogroup.html#addStack)（ ）中，用去除[removeStack](qundogroup.html#removeStack)（ ） 。堆栈是隐式添加到组时，同组创建为其父[QObject](qobject.html)。
这是程序员的责任来指定堆栈积极通过调用[QUndoStack.setActive](qundostack.html#active-prop)（ ） ，通常当相关文档窗口接收焦点。活动堆栈也可与设置[setActiveStack](qundogroup.html#setActiveStack)（） ，并且通过返回[activeStack](qundogroup.html#activeStack)（ ） 。
当一个堆栈使用添加到组[addStack](qundogroup.html#addStack)（ ） ，该组不采取栈的所有权。这意味着在堆栈必须单独从组中删除。当一个堆栈被删除，它会自动从组中删除。堆栈只能属于一个组。将它添加到另一个组将导致它从以前的组中删除。
一个QUndoGroup也是有用会同[QUndoView](qundoview.html)。如果[QUndoView](qundoview.html)设置为观看利用一组[QUndoView.setGroup](qundoview.html#setGroup)（ ） ，它会自动更新以显示当前堆栈。
