QTextDocument line number

[roxton]

Here it is:

QStringList l = textEdit->toPlainText().split (QChar::ParagraphSeparator);
int number_of_lines = l.size();

QStringList l = textEdit->toPlainText().split (QChar::ParagraphSeparator);
int number_of_lines = l.size();

To copy to clipboard, switch view to plain text mode

Thanks, but, doesn't work in my case, I need lines not paragraphes and those are not visible characters.

In QTextDocument, the paragraph is the single line (not wrapped). Paragraphs are the lines that internally separated by QChar::ParagraphSeparator instead of \n. So getting the number of paragraphs, you'll get the count of lines.
