source§fn init(self: Pin<&Self>, _window_adapter: &Rc<dyn WindowAdapter>)
fn init(self: Pin<&Self>, _window_adapter: &Rc<dyn WindowAdapter>)
This function is called by the run-time after the memory for the item
has been allocated and initialized. It will be called before any user specified
bindings are set.
source§fn geometry(self: Pin<&Self>) -> LogicalRect
fn geometry(self: Pin<&Self>) -> LogicalRect
Returns the geometry of this item (relative to its parent item)
source§fn layout_info(
self: Pin<&Self>,
_orientation: Orientation,
_window_adapter: &Rc<dyn WindowAdapter>
) -> LayoutInfo
fn layout_info(
self: Pin<&Self>,
_orientation: Orientation,
_window_adapter: &Rc<dyn WindowAdapter>
) -> LayoutInfo
We would need max/min/preferred size, and all layout info

fn input_event_filter_before_children(
self: Pin<&Self>,
_: MouseEvent,
_window_adapter: &Rc<dyn WindowAdapter>,
_self_rc: &ItemRc
) -> InputEventFilterResult
Event handler for mouse and touch event. This function is called before being called on children.
Then, depending on the return value, it is called for the children, and their children, then
Self::input_event is called on the children, and finally Self::input_event is called
on this item again.source§fn input_event(

) -> InputEventResult
fn input_event(
self: Pin<&Self>,
_: MouseEvent,
_window_adapter: &Rc<dyn WindowAdapter>,
_self_rc: &ItemRc
) -> InputEventResult
Handle input event for mouse and touch event
