disabling widgets and colors.

[Joaquim Duran <joaquinduran adtelecom es>]

Dear all,

Currently, a customer is asking to show pop ups in transparent mode in a 
non-composite X11 environment.

I've done some testing: I've places to containers in overlapped 
positions in a Fixed container. To avoid the focus go to the container 
that simulates the screen, I've made it insensible. When the container 
is insensible, it changes the color to gray.

Is there any way to disable a widget and maintain the same colors that 
when it is sensible?

Thanks in advance,

Joaquim Duran
