 --- First example, a child without scrolling support:
 
+
+
+    {{image_right("scroll-w-help-of-wport.png")}}
+
+    This program displays hundred buttons in a table widget, which does not have native scrolling abilities, therefore we need to first add the table to a viewport widget, and only then add the wiewport to scrolled window. As mentioned this is the long way of using viewport. We could instead just use the Gtk::ScrolledWindow#add_with_viewport(child) instance method. The two approaches can be seen in the listing between the "-- (start/end)" comment lines. This part of the program is only needed when the widget you are adding to scrolled window does not include native support for scrolling.
