[Solved] QTextEdit::undo or QTextDocument::undo

[IIOffensiveII]

Hi everybody.

I'm new to Qt and reading some books.
One of the books I read, there is a text editor example.

Somewhere in the code, the author uses

@textEdit->document()->undo();@

for an undo operation where document() returns a QTextDocument object.
However, I realized that QTextEdit already has an undo function and does the same thing.
Now, sorry for that easy question but is there a difference between them ?

High and welcome to devnet,

QTextEdit's undo will do some internal stuff and call undo on it's document. Calling undo directly on the document will by-pass QTextEdit's internal handling.

Hope it helps

Thank you for your reply.
It is clearer now.
