Gtkmm questions

[eypros]

Hello,

I am learning Gtkmm and trying to figure out the examples in the "Programming with Gtkmm". Anyway I have some question:

1) Is there any forum dedicated to Gtkmm I can address my question? I only found a mailing list (it's OK but I guess a forum might respond faster).

2) I use the examples in this book and wondering if I can get them from somewhere. I have found them in sites like:
http://docs.huihoo.com/gtkmm/examples/
but it's frustrating to download each file individually.

3) In the examples polymorphism is used for member functions like in the 6.2 example:
virtual void on_checkbox_editable_toggled();

I guess all the advantages of redefining virtual function are apply also here but some questions came up. If I have 2 checkboxes for example how can I write code for each checkbox. I can use 2 functions but then they won't be overloaded and polymorphism is gone. Correct?
By defining

void on_checkbox1_editable_toggled();
void on_checkbox2_editable_toggled();

for instance I get 2 function but none virtual. (it works but no polymorphism).
Am I missing something here?

Thanks for any reply
