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