Type Definition pushrod::render::callbacks::FunctionPointParametersType

type FunctionPointParametersType = Option<Box<dyn FnMut(&mut dyn Widget, &[WidgetContainer], &[LayoutContainer], Vec<i32>)>>;

This is an FnMut that takes a Point as a Vec<i32> of points: X and Y, returning a mutable reference to the current Widget, and borrowing the WidgetContainer and LayoutContainer lists.
