Need help with text entry background

[Preben Randhol <randhol dusken4 samfundet ntnu no>]

I have a text entry which I have defined not editable. In order to
clarify for the user that he cannot edit this value I want to change
the white background to the normal grey background colour. In this way
only when the background is white is it editable...  

If somebody has a tip or example code of this, it would make me very
happy:)

Please...

Thanks in advance.
