First of all I apologize for my bad english I am beginner in writing GUI apps with Glade and python, i am having problem with libglade.. well I know that glade-3 hasn't yet good implementation with gtkbuilder, so python users are saving projects in libglade format, and then we convert it with: gtk-builder-convert, to bring up our xml file in gtkbuilder format. Here is my problem, I need treeview, but treeview can only be used in glade if we are saving our project in gtkbuilder format, but i need to use libglade format because i have to convert it with gtk-builder-conver.. So my question is, how can I insert treeview :S
