I have to agree with Gopalakrishna: it is not a good idea to make the 
button appear as if it is enabled, while it is not. It is confusing for 
the user, and will be frustrating in use. There are very good reasons 
for the visual difference. Let the style (which is ideally the platform 
style) determine how enabled and disabled controls appear.

Having said that: an alternative approach for the event filter solution 
is to use your own proxy style. You can easily manipulate the style 
option state flags to be always enabled. I think that solution is easier 
than using event filters.
