Re: Blocking signals

[Paolo Costabel <paolo zebradevelopment com>]

This is one of the recurring problems in GTK.
If you only want to block your own handlers, the easiest way is to have 
a global flags
that every handler checks to determine whether or not it should execute.
It is not elegant, but it's easy and failproof. Of course if you are 
trying to block default handlers
this might not work, but usually you only care about your own handlers.
