GtkButton relief

[Christian Schaubschlaeger <cs gup uni-linz ac at>]

Hello,

I can inhibit drawing of a button's relief by setting
the "relief" property to "GTK_RLIEF_NONE". Unfortunately
a relief is still drawn as soon as the mouse cursor
moves over the button (ie. the button becomes 'highlighted').
Is it possible to disable this too? I want the button to
remain unchanged when the mouse moves over it.

Thanks and best regards
Christian
