hi, there!
in my app, i create some new wighets in a created parent wighet.
when i click somewhere, i want to clear the parent wighet's all child, and create other new wighets in this parent wighet.
how can i do to clear the parent wighet's all wighet.
i noticed that there is a method _destroyAllChildWidget(), but it is protected.
