Signals
Loading
loadStarted :: WebViewClass self => Signal self (WebFrame -> IO ()) Source
When a WebFrame begins to load, this signal is emitted
loadCommitted :: WebViewClass self => Signal self (WebFrame -> IO ()) Source
When a WebFrame loaded the first data, this signal is emitted
progressChanged :: WebViewClass self => Signal self (Int -> IO ()) Source
When the global progress changed, this signal is emitted
the global progress will be passed back to user function
loadFinished :: WebViewClass self => Signal self (WebFrame -> IO ()) Source
When loading finished, this signal is emitted
loadError :: (WebViewClass self, GlibString string) => Signal self (WebFrame -> string -> GError -> IO Bool) Source
When An error occurred while loading.
By default, if the signal is not handled, the WebView will display a stock error page.
You need to handle the signal if you want to provide your own error page.
The URI that triggered the error and the GError will be passed back to user function.
iconLoaded :: (WebViewClass self, GlibString string) => Signal self (string -> IO ()) Source
Emitted after Icon loaded
documentLoadFinished :: WebViewClass self => Signal self (WebFrame -> IO ()) Source
When document loading finished, this signal is emitted
resourceRequestStarting :: WebViewClass self => Signal self (WebFrame -> WebResource -> Maybe NetworkRequest -> Maybe NetworkResponse -> IO ()) Source
Emitted when a request is about to be sent.
You can modify the request while handling this signal.
You can set the URI in the NetworkRequest object itself,
and addremovereplace headers using the SoupMessage object it carries,
if it is present. See networkRequestGetMessage.
Setting the request URI to "about:blank" will effectively cause the request to load nothing,
and can be used to disable the loading of specific resources.
Notice that information about an eventual redirect is available in response's SoupMessage, not in the SoupMessage carried by the request. If response is NULL, then this is not a redirected request.
The WebResource object will be the same throughout all the lifetime of the resource,
but the contents may change from inbetween signal emissions.
titleChanged :: (WebViewClass self, GlibString string) => Signal self (WebFrame -> string -> IO ()) Source
Clipboard
copyClipboard :: WebViewClass self => Signal self (IO ()) Source
The copyClipboard signal is a keybinding signal which gets emitted to copy the selection to the clipboard.
The default bindings for this signal are Ctrl-c and Ctrl-Insert.
cutClipboard :: WebViewClass self => Signal self (IO ()) Source
The cutClipboard signal is a keybinding signal which gets emitted to cut the selection to the clipboard.
The default bindings for this signal are Ctrl-x and Shift-Delete.
pasteClipboard :: WebViewClass self => Signal self (IO ()) Source
The pasteClipboard signal is a keybinding signal which gets emitted to paste the contents of the clipboard into the Web view.
The default bindings for this signal are Ctrl-v and Shift-Insert.
Script
consoleMessage :: (WebViewClass self, GlibString string) => Signal self (string -> string -> Int -> string -> IO Bool) Source
A JavaScript console message was created.
scriptAlert :: (WebViewClass self, GlibString string) => Signal self (WebFrame -> string -> IO Bool) Source
A JavaScript alert dialog was created.
scriptConfirm :: (WebViewClass self, GlibString string) => Signal self (WebFrame -> string -> IO Bool) Source
A JavaScript confirm dialog was created, providing Yes and No buttons.
scriptPrompt :: (WebViewClass self, GlibString string) => Signal self (WebFrame -> string -> string -> IO Bool) Source
A JavaScript prompt dialog was created, providing an entry to input text.
statusBarTextChanged :: (WebViewClass self, GlibString string) => Signal self (string -> IO ()) Source
When status-bar text changed, this signal will emitted.
populatePopup :: WebViewClass self => Signal self (Menu -> IO ()) Source
When a context menu is about to be displayed this signal is emitted.
Selection/edition
editingBegan :: WebViewClass self => Signal self (IO ()) Source
editingEnded :: WebViewClass self => Signal self (IO ()) Source
selectAll :: WebViewClass self => Signal self (IO ()) Source
The selectAll signal is a keybinding signal which gets emitted to select the complete contents of the text view.
The default bindings for this signal is Ctrl-a.
selectionChanged :: WebViewClass self => Signal self (IO ()) Source
When selection changed, this signal is emitted.
Decision request
mimeTypePolicyDecisionRequested :: (WebViewClass self, GlibString string) => Signal self (WebFrame -> NetworkRequest -> string -> WebPolicyDecision -> IO Bool) Source
Decide whether or not to display the given MIME type. If this signal is not handled, the default behavior is to show the content of the requested URI if WebKit can show this MIME type and the content disposition is not a download; if WebKit is not able to show the MIME type nothing happens.
Notice that if you return True, meaning that you handled the signal,
you are expected to be aware of the Content-Disposition header.
A value of "attachment" usually indicates a download regardless of the MIME type,
see also soupMessageHeadersGetContentDisposition'
And you must call webPolicyDecisionIgnore, webPolicyDecisionDownload, or webPolicyDecisionUse
on the webPolicyDecision object.
navigationPolicyDecisionRequested :: WebViewClass self => Signal self (WebFrame -> NetworkRequest -> WebNavigationAction -> WebPolicyDecision -> IO Bool) Source
Emitted when frame requests a navigation to another page. If this signal is not handled, the default behavior is to allow the navigation.
Notice that if you return True, meaning that you handled the signal,
you are expected to be aware of the Content-Disposition header.
A value of "attachment" usually indicates a download regardless of the MIME type,
see also soupMessageHeadersGetContentDisposition'
And you must call webPolicyDecisionIgnore, webPolicyDecisionDownload, or webPolicyDecisionUse
on the webPolicyDecision object.
newWindowPolicyDecisionRequested :: WebViewClass self => Signal self (WebFrame -> NetworkRequest -> WebNavigationAction -> WebPolicyDecision -> IO Bool) Source
Emitted when frame requests opening a new window.
With this signal the browser can use the context of the request to decide about the new window.
If the request is not handled the default behavior is to allow opening the new window to load the URI,
which will cause a createWebView signal emission where the browser handles the new window action
but without information of the context that caused the navigation.
The following navigationPolicyDecisionRequested emissions will load the page
after the creation of the new window just with the information of this new navigation context,
without any information about the action that made this new window to be opened.
Notice that if you return True, meaning that you handled the signal,
you are expected to be aware of the Content-Disposition header.
A value of "attachment" usually indicates a download regardless of the MIME type,
see also soupMessageHeadersGetContentDisposition'

createWebView :: WebViewClass self => Signal self (WebFrame -> IO WebView) Source
webViewReady :: WebViewClass self => Signal self (IO Bool) Source
closeWebView :: WebViewClass self => Signal self (IO Bool) Source
Emitted when closing a WebView is requested.
This occurs when a call is made from JavaScript's window.close function.
The default signal handler does not do anything.
It is the owner's responsibility to hide or delete the WebView, if necessary.
User function should return True to stop the handlers from being invoked for the event or False to propagate the event furter
printRequested :: WebViewClass self => Signal self (WebFrame -> IO Bool) Source
Emitted when printing is requested by the frame, usually because of a javascript call.
When handling this signal you should call webFramePrintFull or webFramePrint to do the actual printing.
The default handler will present a print dialog and carry a print operation. Notice that this means that if you intend to ignore a print request you must connect to this signal, and return True.

downloadRequested :: WebViewClass self => Signal self (Download -> IO Bool) Source
Emitted after A new Download is being requested.
By default, if the signal is not handled, the download is cancelled.
Notice that while handling this signal you must set the target URI using downloadSetDestinationUri
If you intend to handle downloads yourself, return False in user function.
