Struct UpdateDeliveryList

source
pub struct UpdateDeliveryList { /* private fields */ }
Expand description

Represents all the widgets and windows marked to receive an update.

Implementations§

source§

impl UpdateDeliveryList

source

pub fn new(subscribers: Box<dyn UpdateSubscribers>) -> Self

New list that only allows subscribers.

source

pub fn new_none() -> Self

New list that does not allow any entry.

source

pub fn new_any() -> Self

New list that allows all entries.

This is the default value.

source

pub fn insert_wgt(&mut self, wgt: &impl WidgetPathProvider)

Insert the wgt and ancestors up-to the inner most that is included in the subscribers.

source

pub fn insert_window(&mut self, id: WindowId)

Insert the window by itself, the window root widget will be targeted.

source

pub fn search_all(&mut self)

Register all subscribers for search and delivery.

source

pub fn search_widget(&mut self, widget_id: WidgetId)

Register the widget of unknown location for search before delivery routing starts.

If the list has pending widgets that must be found before delivery can start.

Search all pending widgets in all windows, all search items are cleared, even if not found.

source

pub fn enter_window(&self, window_id: WindowId) -> bool

Returns true if the window is on the list.

source

pub fn enter_widget(&self, widget_id: WidgetId) -> bool

Returns true if the widget is on the list.

source

pub fn windows(&self) -> &IdSet<WindowId>

Windows in the delivery list.

source

pub fn widgets(&self) -> &IdSet<WidgetId>

Found widgets in the delivery list, can be targets or ancestors of targets.

source

pub fn search_widgets(&mut self) -> &IdSet<WidgetId>

Widgets still pending search or not found.

source

pub fn search_root(&mut self) -> bool

If search for window a root is pending.
