[Qt-interest] Make a few lines of a QTextEdit uneditable?

[Ender EREL]

You can connect a slot to the textChanged() signal of your QTextEdit, 
and in that slot, you can compare the new text with the previous text (i 
think you have to manually store the old text) and revert any changes 
that you don't want to allow.

I don't know if there is a more elegant way to achieve this. I also 
think that this method may cause a little slowness while typing.
