Event args for the NavigationStarting event.

Required Methods

unsafe fn get_uri(&self, uri: *mut LPWSTR) -> HRESULT

The uri of the requested navigation.

unsafe fn get_is_user_initiated(&self, is_user_initiated: *mut BOOL) -> HRESULT

TRUE when the navigation was initiated through a user gesture as opposed to programmatic navigation by page script. Navigations initiated via WebView2 APIs are considered as user initiated.

unsafe fn get_is_redirected(&self, is_redirected: *mut BOOL) -> HRESULT

TRUE when the navigation is redirected.

unsafe fn get_request_headers( &self, request_headers: *mut *mut *mut ICoreWebView2HttpRequestHeadersVTable, ) -> HRESULT

The HTTP request headers for the navigation.

> [!NOTE]\n> You are not able to modify the HTTP request headers in a NavigationStarting event.

unsafe fn get_cancel(&self, cancel: *mut BOOL) -> HRESULT

The host may set this flag to cancel the navigation. If set, the navigation is not longer present and the content of the current page is intact. For performance reasons, GET HTTP requests may happen, while the host is responding. You may set cookies and use part of a request for the navigation. Cancellation for navigation to about:blank or frame navigation to srcdoc is not supported. Such attempts are ignored.

unsafe fn put_cancel(&self, cancel: BOOL) -> HRESULT

Sets the Cancel property.

unsafe fn get_navigation_id(&self, navigation_id: *mut u64) -> HRESULT

The ID of the navigation.
