## Detailed Description
該QUndoGroup類是一組[QUndoStack](qundostack.html)對象。
對于Qt的撤消框架的概述，請參閱[overview](index.htm)。
一個應用程序通常有多個撤消堆棧，每一個打開的文檔。與此同時，應用程序通常有一個撤消操作和一個重做動作，這會觸發撤消或重做的活動文檔。
QUndoGroup是一組[QUndoStack](qundostack.html)物，其中之一可以是活動的。它有一個[undo](qundogroup.html#undo)（）和[redo](qundogroup.html#redo)（）槽，它調用[QUndoStack.undo](qundostack.html#undo)（）和[QUndoStack.redo](qundostack.html#redo)（ ）為活動堆棧。它還具有功能[createUndoAction](qundogroup.html#createUndoAction)（）和[createRedoAction](qundogroup.html#createRedoAction)（ ） 。這些函數返回的動作相同的行為方式的那些返回[QUndoStack.createUndoAction](qundostack.html#createUndoAction)（）和[QUndoStack.createRedoAction](qundostack.html#createRedoAction)活動堆棧的（） 。
堆棧被添加到一個組[addStack](qundogroup.html#addStack)（ ）中，用去除[removeStack](qundogroup.html#removeStack)（ ） 。堆棧是隱式添加到組時，同組創建為其父[QObject](qobject.html)。
這是程序員的責任來指定堆棧積極通過調用[QUndoStack.setActive](qundostack.html#active-prop)（ ） ，通常當相關文檔窗口接收焦點。活動堆棧也可與設置[setActiveStack](qundogroup.html#setActiveStack)（） ，并且通過返回[activeStack](qundogroup.html#activeStack)（ ） 。
當一個堆棧使用添加到組[addStack](qundogroup.html#addStack)（ ） ，該組不采取棧的所有權。這意味著在堆棧必須單獨從組中刪除。當一個堆棧被刪除，它會自動從組中刪除。堆棧只能屬于一個組。將它添加到另一個組將導致它從以前的組中刪除。
一個QUndoGroup也是有用會同[QUndoView](qundoview.html)。如果[QUndoView](qundoview.html)設置為觀看利用一組[QUndoView.setGroup](qundoview.html#setGroup)（ ） ，它會自動更新以顯示當前堆棧。
