Yes but I don't want to show all the widgets. I'm using a manually created arrow browsable menu inside a box. There are 10 browsable entries (I don't use GtkList browsing; I made my own) showing and when I reach the bottom of the showing entries, if there are more entries, the topmost entry gets a gtk_widget_hide and the new entry that isnt showing yet at the bottom gets a gtk_widget_show. Its basically like a viewport with 10 entries or less showing. The GtkList serving mostly only as a container.

I understand this might not be the best but I learnt GTK+ not too long ago and without much of any documentation about what I needed to knows so... :).

I use GTK+ 2.0

Heheh, but i don't need support, it works fine.

 And if you don't know yet

Now I know what CVS is and I don't see what the h*** this has to do with my problem. It mostly just sounds like he was trying to plug in his pet developping environment :). I don't need to add this CVS infrastructure to my project. I'm working alone on it anyways so there's no point using such a tool for now. Lets keep it simple :). On a later project maybe. Not right now. The project is already underway and I am not changing developing environment just for the fun of it.
