Highlighting word by word

[arumita]

Hi
What i want is this : open a text file, have a pointer for words in the text, move it (the pointer) word by word (sequentially from the beginning till end of the text) , and highlight these words one by one according to the movement of the pointer ----> as a result the output will show text and the highlighting is moving word by word from the beginning of the text with some delay.
So i did open text file using qtextedit .. that's it
my questions are:
- choosing qtextedit in this case is correct or not?? if not what should i use??
- how to use pointer for words???
- how to do the highlighting????
i'm finding here a lot of possibilities but i'm confused
Any help or advice will be greatly appreciated
thnx

Access the QTextDocument that underlies the QTextEdit. You can then create a QTextCursor into the document and use something like:

cursor->movePosition(QTextCursor::StartOfWord, QTextCursor::MoveAnchor);
cursor->movePosition(QTextCursor::EndOfWord, QTextCursor::KeepAnchor);

cursor->movePosition(QTextCursor::StartOfWord, QTextCursor::MoveAnchor);
cursor->movePosition(QTextCursor::EndOfWord, QTextCursor::KeepAnchor);

To copy to clipboard, switch view to plain text mode 

to highlight the current word, and:

cursor->movePosition(QTextCursor::NextWord, QTextCursor::MoveAnchor);
cursor->movePosition(QTextCursor::EndOfWord, QTextCursor::KeepAnchor);

cursor->movePosition(QTextCursor::NextWord, QTextCursor::MoveAnchor);
cursor->movePosition(QTextCursor::EndOfWord, QTextCursor::KeepAnchor);

To copy to clipboard, switch view to plain text mode 

to move along a word.

Thank you so much ChrisW67 for your help,
so pointer for words done , but moving the pointer and highlighting is still not clear for me
