Struct CloseRequest 

pub struct CloseRequest {
    pub vetoed: bool,
}

Emitted by window backends on WindowEvent::CloseRequested. Apps that want to veto the close (e.g. to show a “save before quit?” dialog) set vetoed = true in a system reading this message; if no system vetoes, the backend exits the event loop on the next about_to_wait.

Vetoing here mirrors QCloseEvent::ignore() and GTK4’s close-request -> TRUE.

Fields

vetoed: bool

Set by an app system to keep the window open.
