How to "grey out" items?

["David J. Topper" <topper virginia edu>]

Hi all,

Getting back into GTK again.  Trying to expand my little application
into different windows and such.  I'm trying to create a "main" window
which, among other things, establishes a connection to a server
process.  But once the user clicks on "connect" I want all the other
widgets (eg., text boxes, range widgets, pulldowns) to be "greyed out"
so that you can still see values but not edit anything.

Is this possible?

Email responses preferred.

Thanks,

DT
