103 To get a Widget's current parent, use :cpp:expr:`lv_obj_get_parent(widget)`.
105 You can move the Widget to a new parent with :cpp:expr:`lv_obj_set_parent(widget, new_parent)`.
107 To get a specific child of a parent use :cpp:expr:`lv_obj_get_child(parent, idx)`.
114 You can iterate through a parent Widget's children like this:
119 for(i = 0; i < lv_obj_get_child_count(parent); i++) {
120 lv_obj_t * child = lv_obj_get_child(parent, i);
124 :cpp:expr:`lv_obj_get_index(widget)` returns the index of the Widget in its parent.
125 It is equivalent to the number of older children in the parent.
130 You can change the index of a Widget in its parent using :cpp:expr:`lv_obj_move_to_index(widget, in…
