* [method@Gtk.TreeExpander.set_child] sets the widget that displays

*
* `GtkTreeExpander` can be modified with properties such as [property@Gtk.indent-for-icon],
* [property@Gtk.indent-for-depth], and [property@Gtk.hide-expander] to achieve a
* different appearance. This can even be done to influence individual rows, for example
* by binding the [property@Gtk.hide-expander] property to the treelistrow's model's
* item count to hide the expander for rows without children, even if the row is
* expandable.
