<h3 class="fn"><a name="redo" />QUndoCommand.redo (<i>self</i>)</h3><p>Applies a change to the document. This function must be implemented in the derived class. Calling <a href="qundostack.html#push">QUndoStack.push</a>(), <a href="qundostack.html#undo">QUndoStack.undo</a>() or <a href="qundostack.html#redo">QUndoStack.redo</a>() from this function leads to undefined beahavior.</p>

<h3 class="fn"><a name="undo" />QUndoCommand.undo (<i>self</i>)</h3><p>Reverts a change to the document. After undo() is called, the state of the document should be the same as before <a href="qundocommand.html#redo">redo</a>() was called. This function must be implemented in the derived class. Calling <a href="qundostack.html#push">QUndoStack.push</a>(), <a href="qundostack.html#undo">QUndoStack.undo</a>() or <a href="qundostack.html#redo">QUndoStack.redo</a>() from this function leads to undefined beahavior.</p>

89
<p>The default implementation calls undo() on all child commands in reverse order.</p>
