Fl_Tree::remove(Fl_Tree_Item* item)

    Remove the specified 'item' from the tree.

    'item' may not be NULL. If the item has children, all those are removed too.
    If item being removed has focus, no item will have focus.

    remove() frees the memory associated with the specified Fl_Tree_Item immediately.
    remove() does not affect any FLTK widget assigned to the item with Fl_Tree_Item::widget(),

    To destroy an FLTK widget assigned to the item, you can do that cleanly this way:

    Hmm, it might be better to move the description of how to remove a widget assigned to an item
    with Fl_Tree_Item::widget() to the docs for that method, and simply refer to that here
    in remove()'s docs, e.g.

remove() does not destroy any FLTK widget assigned to the item with widget(Fl_Widget*).
For more on how to manage that, see Fl_Tree_Item::widget().

    This way anyone not even using widget() assignment doesn't have to see a lot of detail
    in the remove() docs that doesn't concern them.
