Hello.
I'm adding undo stack to my app. But in the documentation I found:
voidQUndoStack::push(QUndoCommand <qundocommand.html>*cmd)
Pushes cmd on the stack or merges it with the most recently executed
command. In either case, executes cmd by calling its redo
<qundostack.html#redo>() function.
And in sources:
void QUndoStack::push(QUndoCommand *cmd)
{
Q_D(QUndoStack);
cmd->redo();
So my question is why just pushed to the stack undo command executes?
I.e. why cmd->redo() calls in push()?
If I understand all correctly then cmd->redo() should be called only in
QUndoStack::redo() method. And in push I just want to push new undo
command to the stack...
