g_signal_handlers_block_by_func

[Neil Zanella <nzanella gmail com>]

Hello,

I would like to know whether the function call

g_signal_handlers_block_by_func

can be applied to (external) events in the same way as it can be applied
to (internal) Gtk signals so as to temporarily block them and then call

g_signal_handlers_unblock_by_func

Do both of these work on external events in the same way as they do on
internal signals?
And if not, then is there an analogous function for temporarily
blocking handlers external
events which work as the two mentioned above?

Thanks,

Neil
