QTextEdit - Finding text within selection

[ChrisW67]

<warning type="top of head" />

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.
