Hello all. I finally got back from my weekend trip out of town, and finally got the mess my cats made cleaned up. Attached is a patch for cdebconf that adds a gtk2.0 frontend. It is relatively complete. The select and text handlers are not finished, but there is enough to be tested here. I was unable to figure out the cdebconf tests dir, so if someone can explain to me how they work, I can do much better testing on it myself. For now, I've just been making little "hello world" type apps to test the functionality of each handler. The multiselect, password, string and note handlers are ready. Still to be done is to figure out a better way to manage the flow. As it is, I'm creating a new dialog for each question and calling gtk_main each time. This can probably be improved. Also, the select handler uses a radio button, but as I had no net access and only had access to gtk2.0-doc, I couldn't finish it, as the examples there are not very complete. It works as long as you don't select the first radio button. Lastly ,the text handler is mostly incomplete. The widget is created, but I'm not extracting the data entered in it. It still has lots of formatting to do. In addition, since gtk relies heavily on callback functions, I put most of my data in global variables (YUCK!). I need a little bit of explanation on this "c file as class" thing so that I can fix that. Another issue is the actual visual layout. I need to work on that more, once I get a look at some more documentation. The next and back buttons need to be right justified and the dialog needs to be fullscreen. So, this needs a lot more work, that I will continue to do, but I think it's a good enough start to be looked over, and possibly tested. Another issue at hand, now that this is almost ready, is the question of udebs for X and gtk. Should I start on those? Or can we safely assume that the X install medium is going to have lots of space, and thus use regular debs. I don't mind working on the udebs, I just want to know what you guys think. Also, I haven't tested my change to configure yet, as I didn't have autoconf handy, but it looks right to me.
