sourcefn init(self: Pin<&Self>, _window: &WindowRc)
fn init(self: Pin<&Self>, _window: &WindowRc)
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. Read more
sourcefn geometry(self: Pin<&Self>) -> Rect
fn geometry(self: Pin<&Self>) -> Rect
Returns the geometry of this item (relative to its parent item)
sourcefn layout_info(
self: Pin<&Self>,
orientation: Orientation,
_window: &WindowRc
) -> LayoutInfo
fn layout_info(
self: Pin<&Self>,
orientation: Orientation,
_window: &WindowRc
) -> LayoutInfo
We would need max/min/preferred size, and all layout info
sourcefn input_event_filter_before_children(
self: Pin<&Self>,
_: MouseEvent,
_window: &WindowRc,
_self_rc: &ItemRc
) -> InputEventFilterResult
fn input_event_filter_before_children(
self: Pin<&Self>,
_: MouseEvent,
_window: &WindowRc,
_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. Read more
