QTextEdit ??Yes QTextEdit.

Can you tell me, how you are getting the selected text ?
I guess you have to change line wrap and word wrap properties to QTextEdit::NoWrap

[bismitapadhy]

How you are getting the selected text ?QTextCursor.selectedText();

I got your problem.

If the selection obtained from an editor spans a line break, the text will contain a Unicode U+2029 paragraph separator character instead of a newline \n character. Use QString::replace() to replace these characters with newlines. enjoy :)

check this is working:

if(selection.contains(QChar::ParagraphSeparator) || selection.contains(QChar::LineSeparator))
QMessageBox::information(this,tr("Editor"),tr("selected string is multiline"));
