Struct WindowClosingEventArgs 

pub struct WindowClosingEventArgs { /* private fields */ }

Provides data for the window closing event.

The args are a reference object: a copy shares the cancel flag with the args it was made from, so that a handler given a copy cancels the closing, and copies compare by identity.

Implementations

impl WindowClosingEventArgs

pub fn cancel(&self) -> bool

Whether the event should be canceled.

pub fn set_cancel(&self, value: bool)

Sets whether the event should be canceled.

pub fn close_reason(&self) -> WindowCloseReason

Gets a value that indicates why the window is being closed.

pub fn is_programmatic(&self) -> bool

Gets a value indicating whether the window is being closed programmatically.
