Flags a widget to be displayed. Any widget that isn’t shown will
not appear on the screen. If you want to show all the widgets in a
container, it’s easier to call gtk_widget_show_all() on the
container, instead of individually showing the widgets.
Remember that you have to show the containers containing a widget,
in addition to the widget itself, before it will appear onscreen.
When a toplevel container is shown, it is immediately realized and
mapped; other shown widgets are realized and mapped when their
toplevel container is realized and mapped.
