    Default QPlainTextEdit find a multiline text block

    Hello - I am creating a text editor for source code displayed in a QPlainTextEdit. I need to position the current text cursor at a block of text that may span several lines. Is there a way to use find() to locate text with several embedded newline characters? My test case is
    Qt Code:
    1. "ItemsEnableSet {\n MenuTag( 3220 )\n Enable( true )\n}"
    To copy to clipboard, switch view to plain text mode 
    . This is an exact match with a portion of the string in QPlainTextEdit and I can use simplify() on both strings to get a match (but then can't map back into the un-simplified string). I've tried creating a QRegularExpression with /S+ and .+ (with the dot match option enabled) and tried both find() and indexOf(). I can only match up to the first \n in the string. So I wonder if it's possible to match a multiline text? If it is possible can you give some insight on how to create the regular expression?

    If you don't have it working yet, can you post your regular expression and the code where you use find()? I'll see if i can modify it to get it to work.

    Please use CODE tags when posting source code so it is more readable. Click "Go Advanced" and then the "#" icon to insert the tags. Paste your code between them.
