Re: making buttons disable and enable

[Deepak Gupta <dgupta mahindrabt com>]

thanx Mihai for ur ideas
        but i think there has to some other way for accomplishing this job, i.e.
calling GTK+ function calls from other thread.
        if what u say is true then how is it possible that in 'kfind' tool the
'start search' tool button remains disabled as long as the search is going on and as
soon as the search stops it resumes.
        is there any way to hack the 'gtk_main' thread???
