QTextEdit - Finding text within selection

Hello,

I am creating a "find" dialog for my text editor. I have the basic functionality working but I'm not having any luck with limiting the search to a selection only (this is a great feature in many code editors).

Here's where I am so far (This is the slot):

Code:

---

void MainWindow::findString(const QString str, int flags, bool selectionOnly)
{
    QTextDocument::FindFlags ff = (QTextDocument::FindFlags)flags;
    if(selectionOnly)
       <Code for finding within selection goes here>
    else
       currentEditor->find(str,ff); // currentEditor is a QTextEdit
}

---

What would be the most efficient way to limit the search to only the selected text?

Any help is appreciated.

How about something like this:

• Grab the QTextEdit::textCursor()
• If no selection then return?
• Position newcursor at start of selection
• Execute newcursor = find(str, newcursor, opts)
• If newcursor still inside selection then report match and repeat find(). You have operator<() to compare cursors, or you can use the start or end positions manually.
