If the connection is not HTTPS, this function returns False. This function should be called after a response has been received from the server, so you can connect to loadChanged and call this function when it's emitted with LoadEventCommitted event.

Note that this function provides no information about the security of the web page if the current TLSErrorsPolicy is wEBKITTLSERRORSPOLICYIGNORE, as subresources of the page may be controlled by an attacker. This function may safely be used to determine the security status of the current page only if the current TLSErrorsPolicy is wEBKITTLSERRORSPOLICYFAIL, in which case subresources that fail certificate verification will be blocked.

baseUri: the base URI for relative locations or Nothing

-> m ()

Load the given content string for the URI contentUri. This allows clients to display page-loading errors in the WebView itself. When this method is called from loadFailed signal to show an error page, then the back-forward list is maintained appropriately. For everything else this method works the same way as webViewLoadHtml.

loadBytes

webViewLoadBytes

Arguments

:: (HasCallStack, MonadIO m, IsWebView a)

=> a

webView: a WebView

-> Bytes

bytes: input data to load

-> Maybe Text

If baseUri is not Nothing, relative URLs in the content will be resolved against baseUri and absolute local paths must be children of the baseUri. For security reasons absolute local paths that are not children of baseUri will cause the web process to terminate. If you need to include URLs in content that are local paths in a different directory than baseUri you can build a data URI for them. When baseUri is Nothing, it defaults to "about:blank". The mime type of the document will be "text/html". You can monitor the load operation by connecting to loadChanged signal.

Returns: The newly created WebView widget

Creates a new WebView sharing the same web process with webView. This method doesn't have any effect when ProcessModelSharedSecondaryProcess process model is used, because a single web process is shared for all the web views in the same WebContext. When using ProcessModelMultipleSecondaryProcesses process model, this method should always be used when creating the WebView in the create signal.

decidePolicy

type C_WebViewDecidePolicyCallback = Ptr () -> Ptr PolicyDecision -> CUInt -> Ptr () -> IO CInt

Type for the callback on the (unwrapped) C side.

type WebViewDecidePolicyCallback

Arguments

 = PolicyDecision

decision: the PolicyDecision

-> PolicyDecisionType

decisionType: a PolicyDecisionType denoting the type of decision

-> IO Bool

Returns: True to stop other handlers from being invoked for the event. False to propagate the event further.

This signal is emitted when WebKit is requesting the client to decide a policy decision, such as whether to navigate to a page, open a new window or whether or not to download a resource. The NavigationPolicyDecision passed in the decision argument is a generic type, but should be casted to a more specific type when making the decision. For example:

<informalexample><programlisting> static gboolean decide_policy_cb (WebKitWebView *web_view, WebKitPolicyDecision *decision, WebKitPolicyDecisionType type) { switch (type) { case WEBKIT_POLICY_DECISION_TYPE_NAVIGATION_ACTION: { WebKitNavigationPolicyDecision *navigation_decision = WEBKIT_NAVIGATION_POLICY_DECISION (decision); /<!-- -->* Make a policy decision here. *<!-- -->/ break; } case WEBKIT_POLICY_DECISION_TYPE_NEW_WINDOW_ACTION: { WebKitNavigationPolicyDecision *navigation_decision = WEBKIT_NAVIGATION_POLICY_DECISION (decision); /<!-- -->* Make a policy decision here. *<!-- -->/ break; } case WEBKIT_POLICY_DECISION_TYPE_RESPONSE: WebKitResponsePolicyDecision *response = WEBKIT_RESPONSE_POLICY_DECISION (decision); /<!-- -->* Make a policy decision here. *<!-- -->/ break; default: /<!-- -->* Making no decision results in policyDecisionUse. *<!-- -->/ return FALSE; } return TRUE; } </programlisting></informalexample>

It is possible to make policy decision asynchronously, by simply calling objectRef on the decision argument and returning True to block the default signal handler. If the last reference is removed on a PolicyDecision and no decision has been made explicitly, policyDecisionUse will be the default policy decision. The default signal handler will simply call policyDecisionUse. Only the first policy decision chosen for a given PolicyDecision will have any affect.

loadChanged

type C_WebViewLoadChangedCallback = Ptr () -> CUInt -> Ptr () -> IO ()

Type for the callback on the (unwrapped) C side.

type WebViewLoadChangedCallback

Arguments

 = LoadEvent

loadEvent: the LoadEvent

-> IO ()

Emitted when a load operation in webView changes. The signal is always emitted with LoadEventStarted when a new load request is made and LoadEventFinished when the load finishes successfully or due to an error. When the ongoing load operation fails loadFailed signal is emitted before loadChanged is emitted with LoadEventFinished. If a redirection is received from the server, this signal is emitted with LoadEventRedirected after the initial emission with LoadEventStarted and before LoadEventCommitted. When the page content starts arriving the signal is emitted with LoadEventCommitted event.

You can handle this signal and use a switch to track any ongoing load operation.

<informalexample><programlisting> static void web_view_load_changed (WebKitWebView *web_view, WebKitLoadEvent load_event, gpointer user_data) { switch (load_event) { case WEBKIT_LOAD_STARTED: /<!-- -->* New load, we have now a provisional URI *<!-- -->/ provisional_uri = webkit_web_view_get_uri (web_view); /<!-- -->* Here we could start a spinner or update the <!-- -->* location bar with the provisional URI *<!-- -->/ break; case WEBKIT_LOAD_REDIRECTED: redirected_uri = webkit_web_view_get_uri (web_view); break; case WEBKIT_LOAD_COMMITTED: /<!-- -->* The load is being performed.

Emitted when a TLS error occurs during a load operation. To allow an exception for this certificate and the host of failingUri use webContextAllowTlsCertificateForHost.

To handle this signal asynchronously you should call objectRef on certificate and return True.

If False is returned, loadFailed will be emitted. The load will finish regardless of the returned value.

permissionRequest

type C_WebViewPermissionRequestCallback = Ptr () -> Ptr PermissionRequest -> Ptr () -> IO CInt

Type for the callback on the (unwrapped) C side.

type WebViewPermissionRequestCallback

Arguments

 = PermissionRequest

request: the PermissionRequest

-> IO Bool

Returns: True to stop other handlers from being invoked for the event. False to propagate the event further.

This signal is emitted when WebKit is requesting the client to decide about a permission request, such as allowing the browser to switch to fullscreen mode, sharing its location or similar operations.

A possible way to use this signal could be through a dialog allowing the user decide what to do with the request:

<informalexample><programlisting> static gboolean permission_request_cb (WebKitWebView *web_view, WebKitPermissionRequest *request, GtkWindow *parent_window) { GtkWidget *dialog = gtk_message_dialog_new (parent_window, GTK_DIALOG_MODAL, GTK_MESSAGE_QUESTION, GTK_BUTTONS_YES_NO, "Allow Permission Request?"); gtk_widget_show (dialog); gint result = gtk_dialog_run (GTK_DIALOG (dialog));

switch (result) { case GTK_RESPONSE_YES: webkit_permission_request_allow (request); break; default: webkit_permission_request_deny (request); break; } gtk_widget_destroy (dialog);

return TRUE; } </programlisting></informalexample>

It is possible to handle permission requests asynchronously, by simply calling objectRef on the request argument and returning True to block the default signal handler. If the last reference is removed on a PermissionRequest and the request has not been handled, permissionRequestDeny will be the default action.

If the signal is not handled, the request will be completed automatically by the specific PermissionRequest that could allow or deny it. Check the documentation of classes implementing PermissionRequest interface to know their default action.

scriptDialog

type C_WebViewScriptDialogCallback = Ptr () -> Ptr ScriptDialog -> Ptr () -> IO CInt

Type for the callback on the (unwrapped) C side.

type WebViewScriptDialogCallback

Arguments

 = ScriptDialog

dialog: the ScriptDialog to show

-> IO Bool

Returns: True to stop other handlers from being invoked for the event. False to propagate the event further.

Emitted when JavaScript code calls <function>window.alert</function>, <function>window.confirm</function> or <function>window.prompt</function>, or when <function>onbeforeunload</function> event is fired. The dialog parameter should be used to build the dialog. If the signal is not handled a different dialog will be built and shown depending on the dialog type: <itemizedlist> <listitem><para> ScriptDialogTypeAlert: message dialog with a single Close button. </para></listitem> <listitem><para> ScriptDialogTypeConfirm: message dialog with OK and Cancel buttons. </para></listitem> <listitem><para> ScriptDialogTypePrompt: message dialog with OK and Cancel buttons and a text entry with the default text. </para></listitem> <listitem><para> ScriptDialogTypeBeforeUnloadConfirm: message dialog with Stay and Leave buttons. </para></listitem> </itemizedlist>

It is possible to handle the script dialog request asynchronously, by simply caling scriptDialogRef on the dialog argument and calling scriptDialogClose when done. If the last reference is removed on a ScriptDialog and the dialog has not been closed, scriptDialogClose will be called.
