Hello,

My app uses a QPlainTextEdit-derived widget to display some data. The user should be unable to interact with the data in any way.

Currently, in my widget's constructor, I have the following:
Qt Code: 
  1. setReadOnly(true);
  2. setTextInteractionFlags(Qt::NoTextInteraction);
To copy to clipboard, switch view to plain text mode 

This seems to restrict most interactions. However, if the widget has focus, it is still possible to use Ctrl+A to select all the data, then Ctrl+C to copy it to the clipboard.

Is this a bug, or normal behavior? (I use Qt 4.6 btw.)

More importantly, what is the best way to prevent this? The only thing I can think of is writing my own event filter, but that seems a bit overkill/brute-force for what I'm trying to accomplish.

Thanks in advance.
