I did too, I had several applications which had to make the transition and it wasn't a quick job. > (Note: In my understanding, one key difference between GTK 2.0 and > 3.0 is that all the APIs deprecated in 2.0 will be removed in 3.0; > If I'm wrong about that, please tell me!) > > What's the status of the portion of the GTK API that was not > deprecated from the get-go with GTK 2.0, but joined the deprecated > list later, after 2.4?

I just put together quickly a few lists of ALL things marked as deprecated right now. GtkItemFactory is in that list. It will be removed (as I understand it) in 3.0 as will everything else that is marked as deprecated. These lists give you an idea of how much dead code is left in GTK+ right now and why it is so hard to maintain with it lying around. This list is in no way conclusive, it is literally those I looked up in all .h files in the gtk/ directory. There may be others. > Moreover, the new > code would be less efficient than the old (lots of strcmp as > opposed to just looking at integer values from an enumeration). If you find the loading speed so bad that it is affecting performance of your application, please file a bug. If this is not the case, I think the benefits of a *readable* XML format outweigh the inefficiency you talk about. > In addition, I'm not 100% convinced of the virtues of defining a > UI in XML as opposed to via an array of C structs (having both > options would be nice). Glade has been doing this for years. It is much quicker for an application developer to use Glade to define menus, windows, dialogs, etc than it is to code then *statically*. I say statically because you don't need to recompile your program to change some slight detail of the menu layout or labelling. This bears a huge advantage as far as I am concerned. > Gtk-demo has an example where the UI is > defined via a chunk of XML inlined as a C string. This really > sucks, and would be a maintenence nightmare in any real app. What kind of real application are you talking about? I have written many in my time and I use glade for most of them (which uses an XML format for not only the menus but all window layouts). I don't find it a maintenance nightmare at all, in fact it is quite the opposite. > OK, I don't want to be too negative about GtkUIManager; it surely > has its advantages.

I too have had to move from GtkItemFactory to the new GtkUIManager. It wasn't great, but it is needed. I am not saying GtkItemFactory is "evil voodoo" either, I am just saying there are some things in GTK+ that just need to be removed and there are some things application developers are *able* to do as a result of not sealing structures with proper APIs. I should add at this point too, that the GtkItemFactory has been marked as deprecated for some time (since GTK+ 2.4) and the documentation has explicitly said so too. So you have had plenty of time to update your application and/or bring your concerns forward about this. Please do not feel like we don't care about application developers here, many of us are application developers and know we too will have transitions to make for our software where we switch from deprecated APIs. -- Regards, Martyn
