Re: [ruby-gnome2-devel-en] GTK3 TreeView set_select_function support?

[<Ra...@la...>]

Hi Cedlemo,

Thanks again for your help.  I believe I was able to add this support 
correctly, matching the existing coding style.  I have created a pull 
request with my changes.

I was not sure how to create a test case for this as I'm not sure how to 
test this without opening a window.  If this is a deal breaker let me know 
and I will try my best to come up with something.

For what its worth, I was able to verify that it works the same as the 
Gtk2 version as my code is able to run unmodified.  It is now possible to 
prevent the selection in a Gtk TreeView in the case of unsaved changes, 
etc.

Jon
