[cells-devel] Hacking the gtk-ffi

Hi, What are all the things you need to do to add support for a property on a widget. I'm trying to add the "headers-visible" property to the tree-view widget. Here is what I did.... - added the symbol headers-visible to the gtk-slots list in the widget specfication - added the form below to "def-gtk-lib-functions" - made an app with a listbox using that option (gtk-tree-view-set-headers-visible :void ((tree-view :pointer) (visible :gtk-boolean))) I ran the app with debug on but didn't see any calls to the c function. Is there something else you need to do? Any general tips on debugging cells/gtk apps are also welcome. Cheers, Andy
