In this example, a toolbar is used to provide cut, copy paste, and select-all functionality to the Gtk::Entry widget. The main program line (body) creates the toolbar, packing it above the entry widget. It then calls "create_toolbar", which populates the toolbar with tool items and connects the needed signals.

-Again, there is a minor problem here, namely the vertical ((*separator*)) is not yet supported in the current Ryby/GNOME2 (2-0.17.0-rc1) release. Nor does the instance method ((*show_arrow=true*)) yield a desired behaviour!? These are only problems in Ruby implementation, and work in C GTK+ implementation. You can see the both the separator and the arrow features on the image above, as displayed by the toolbars.c - C GTK+ version of our example program.
+There are two images here so you can see all the features this toolbar provides, in particular I wanted you to see the arrow, indicating that there are additional menu items available.

New toolbars are created with Gtk::Toolbar.new. This creates an empty toolbar. We created our toolbar before calling our own method create_toolbar(toolbar, entry), which populates the toolbar.
