public bool hide_expander { get; set; }
Whether the expander icon should be hidden in a GtkTreeListRow.
Note that this property simply hides the icon. The actions and keybinding (i.e. collapse and expand) are not affected by this property.
A common use for this property would be to bind to the number of children in a GtkTreeListRow's model in order to hide the expander when a row has no children.
