Hey ho!
So, here's another patch. It basically changes the GladePalette's
catalog selection implementation. Instead of using individual radio
buttons, I used a GtkComboBox. The reason behind this decision is that
since glade3 has extensible catalog support, we can have more than 4
catalogs in the future. And having individual radio button for each
would ... well would just not be right.
Also, I took the oppurtunity to cleanup the code a bit. Here I would
suggest a little programming tip . Whenever using
g_object_[get/set]_data() functions, for the paramenter name's string,
don't use a string, but use a all caps constant (or a #define, smae
thing). Because if you mis-type it or change it, the compiler will catch
it for you. Plus, if someone decides to change the string he/she must
find all the places in the code where to change and that can be tedious.
Archit
P.S. just incase you are wondering why they curious hello (hey ho). in
my emails, I started thinking the same too, since I usually just wrote
it without thinking about it. Anyway I came with a plausible reason, its
the christmas spirit in me :-)
