    pub timestamp: DInstant,
    pub prev_focus: Option<WindowId>,

WINDOW_FOCUS_CHANGED_EVENT args.

Fields

timestamp: DInstant

Instant the event happened.

prev_focus: Option<WindowId>

Previously focused window.

new_focus: Option<WindowId>

Newly focused window.

closed: bool

If the focus changed because the previously focused window closed.

Implementations

impl WindowFocusChangedArgs

pub fn new( timestamp: impl Into<DInstant>, propagation_handle: EventPropagationHandle, prev_focus: impl Into<Option<WindowId>>, new_focus: impl Into<Option<WindowId>>, closed: impl Into<bool>, ) -> Self

New args from values that convert into the argument types.

pub fn now( prev_focus: impl Into<Option<WindowId>>, new_focus: impl Into<Option<WindowId>>, closed: impl Into<bool>, ) -> Self

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

impl WindowFocusChangedArgs

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

If window_id got focus.

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

If window_id lost focus.

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

If window_id lost focus because it was closed.

pub fn closed(&self) -> Option<WindowId>

Gets the previous focused window if it was closed.
