Quoted
make the QtextEdit item public
If I do this it's the same as making a public function in Window 1 that writes to the TextEdit. My problem is that I don't know how to access Window 1's content, the QTextEdit or the function.
create a friend class for the second window with the first.
I'm sorry but I don't know what a friend class is.
let window 1 be parent to window 2 and post items from window 2 to the parent
How do I do this?
Thanks
