Re: making buttons disable and enable

[Mihai BAZON <mbazon websci ro>]

Gtk+ is _not_ yet thread-safe, AFAIK (and I think it will not be so very
soon).  This means that you cannot make Gtk+ function calls from another
thread but the main thread.  Some people think this is a limitation, I
personally think it's good; it it were thread-safe, it would be much
slower, less portable, etc.  However, you can avoid problems by using
mutexes to protect Gtk+ calls, or (probably better) -- call Gtk+ from a
single thread.  This can be achieved using some sort of communication
mechanism between threads, and when another thread needs to call a Gtk+
function notify the main thread, which will do the shit..

I hope I'm not wrong (I had the same problems too, but I gave up before
solving them.. :)

Good luck!
