In this exercise you should implement the same text editor with a menu bar rather than a toolbar. However, this implementation will be done partly with Glade and partly with Gtk::UIManager. First thing we need to do is design a new Glade layout. The fastest it will be to copy the earlier "ex10-1-editor-tb.glade" file into a new "ex10-2-editor-mb-ui.glade" file and remove the toolbar so the first cell of the vertical box (vbox1) will be empty (mesh). Another change we have to do in "vbox1" is to change the packing order of the children widgets, namely of the "scrolledwindow1" and the "hbox", from "start" to "end". It is premature to explain this now but it is worth drawing your attention in this direction. The next thing we need is our "manu2.ui" file where we have the required menu layout design. Yet another issue that you have to be concerned with is the fact that in Gtk::UIManager designs we prefer Proc callbacks over functions or methods. Again for reasons not yet clear you should try to turn this around, namely use methods for callbacks that used to be Procs.
