Hi,

I still wonder why people would want to connect_after things ??
As a gtk binding, gtk# should follow what is standard in gtk which is
connect_before. (see g_signal_connect ()).

I was told at #mono that i could connect_before extending the class and
overriding the event method. That doesn't work. See the example
attached.

So, what if i want to make the Enter key of a TextView process something
instead of making a new line ? (A very common thing) P/Invoke it ?
Afaik, gtk# was made so i don't have to p/invoke things (beside making
things easier).

Mike Kestner, please take a look at it :) It's very important that
people can write gtk# programs easily, and in my opinion this
connect_after  just make things harder.

The example can be compiled with:

mcs TestEvent.cs -o TestEvent.exe /r:gtk-sharp.dll /r:gnome-sharp.dll
/r:gdk-sharp.dll

(using gtk-sharp from cvs)

Big Hug.
