g_signal_emit: what is "detail" ?

[paolo borelli <pborelli katamail com>]

Hi!

I'm porting some code to gtk2 and I want to replace gtk_signal_emit with
g_signal_emit. I see that g_signal_emit has an additional parameter
called "detail" but I couldn't find what is for and what I have to pass
to it when calling the function...

The docs are a little too terse:

...
detail: the detail
...

So I looked at some other app: I had gnome-terminal handy and there I
saw that it always pass 0 as detail.

Can someone give me some advice and/or point me to more verbose docs?

Thanks in advance

ciao
