指针输入捕获流丢失时引发。

// Register
event_token PointerCaptureLost(TypedEventHandler<IInspectable, PointerEventArgs const&> const& handler) const;

// Revoke with event_token
void PointerCaptureLost(event_token const* cookie) const;

// Revoke with event_revoker
CoreComponentInputSource::PointerCaptureLost_revoker PointerCaptureLost(auto_revoke_t, TypedEventHandler<IInspectable, PointerEventArgs const&> const& handler) const;

public event TypedEventHandler<object,PointerEventArgs> PointerCaptureLost;

function onPointerCaptureLost(eventArgs) { /* Your code */ }
coreComponentInputSource.addEventListener("pointercapturelost", onPointerCaptureLost);
coreComponentInputSource.removeEventListener("pointercapturelost", onPointerCaptureLost);
- or -
coreComponentInputSource.onpointercapturelost = onPointerCaptureLost;
