Type Definition pushrod::render::callbacks::FunctionClickParametersType

type FunctionClickParametersType = Option<Box<dyn FnMut(&mut dyn Widget, &[WidgetContainer], &[LayoutContainer], u8, u8, bool)>>;

This is an FnMut that takes a button click ID, the number of clicks, the click state (true indicating the click was pressed, false otherwise), returning a mutable reference to the current Widget, and borrowing the WidgetContainer and LayoutContainer lists.
