Hi,
I was messing around with Geany code to see what it would take to compile it against GTK+ 3 (just for fun). There doesn't seem to be too many changes needed, with one *massive* exception: the old code generated by old glade versions.
At some point in the (possibly distant) future, Geany will (I think) either need to switch to using GtkBuilder or just hack-by-hand the `interface.c` file (eww), since the old Glade version generates what will be deprecated code, and newer Glade versions don't generate code.
Has anyone thought about what would be needed to switch from using the current generated C UI code to using GtkBuilder? You can actually open the old Glade file in Glade3 and resave it as GtkBuilder XML (with minor issues), but it seems like there would need to be a whole lot of work to actually use it.
At a glance, it seems like most widgets are accessed through `ui_lookup_widget()`, so it seems like it would make sense to have that function somehow call `gtk_builder_get_object()` to find the widget. If all the Glade widgets are lookup up through this single function, that will probably work to our advantage. I'm not sure how else widgets are accessed, or how many are added outside of the `interface.c` file (vte?) or if that matters.
It seems like the callbacks should get connected when `gtk_builder_connect_signals()` is called since they seem to stick around fine in the GtkBuilder XML file. I guess this part might not be too much problem.
I was hoping to start gathering some ideas on the best way to make this transition, even though it may be far off in the future. It seems to me like it will require quite extensive changes, potentially producing tons of non-obvious bugs popping up in obscure corners of the code.
Maybe I'm over-estimating the scope of the change. Is there some silver-bullet approach that will make this trivial?
Cheers, Matthew Brush
