Struct WindowCloseRequestedArgs 

pub struct WindowCloseRequestedArgs {
    pub timestamp: DInstant,
    pub windows: IdSet<WindowId>,
    pub propagation: EventPropagationHandle,
}

WINDOW_CLOSE_REQUESTED_EVENT args.

Requesting propagation().stop() on this event cancels the window close.

Fields

timestamp: DInstant

Instant the event happened.

windows: IdSet<WindowId>

Windows closing, headed and headless.

This is at least one window, is multiple if the close operation was requested as group, cancelling the request cancels close for all windows.

propagation: EventPropagationHandle

Propagation handle associated with this event instance.

Cloned arguments share the same handle, some arguments may also share the handle of another event if they share the same cause.

Implementations

impl WindowCloseRequestedArgs

pub fn new( timestamp: impl Into<DInstant>, propagation: EventPropagationHandle, windows: impl Into<IdSet<WindowId>>, ) -> Self

New args from values that convert into the argument types.

pub fn now(windows: impl Into<IdSet<WindowId>>) -> Self

Arguments for event that happened now (INSTANT.now).

impl WindowCloseRequestedArgs

pub fn headed(&self) -> impl Iterator<Item = WindowId> + '_

Gets only headed windows that will close.

pub fn headless(&self) -> impl Iterator<Item = WindowId> + '_

Gets only headless windows that will close.

Trait Implementations

impl AnyEventArgs for WindowCloseRequestedArgs

fn is_in_target(&self, _id: WidgetId) -> bool

Broadcast to all widgets.

fn timestamp(&self) -> DInstant

Instant this event update happened.

fn propagation(&self) -> &EventPropagationHandle

Propagation handle associated with this event instance.

fn clone_boxed(&self) -> Box<dyn AnyEventArgs>

Clone the args to a new box.

impl Clone for WindowCloseRequestedArgs

fn clone(&self) -> WindowCloseRequestedArgs

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WindowCloseRequestedArgs

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for WindowCloseRequestedArgs

fn eq(&self, other: &WindowCloseRequestedArgs) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
