# This is a bit of fun presenting all available cursor types in a combobox,
# to be set onto the label widget.
#
# It also illustrates one of the failings of the current implementation.
# Gtk2::Label is a no-window widget, as is Gtk2::ComboBox, so a WidgetCursor
# on the label would actually set the toplevel window and show on both label
# and combobox.  Putting the label in a Gtk2::EventBox creates a subwindow
# to confine its effect.
