## Detailed Description

This control may be used to render web (HTML / CSS / javascript) documents.

It is designed to allow the creation of multiple backends for each port, although currently just one is available. It differs from wxHtmlWindow in that each backend is actually a full rendering engine, Internet Explorer or Edge on MSW and WebKit on macOS and GTK. This allows the correct viewing of complex pages with JavaScript and CSS.

# Backend Descriptions

This class supports using multiple backends, corresponding to different implementations of the same functionality. Under macOS and Unix platforms only a single, WebKit-based, backend is currently provided, but under MSW both the legacy IE backend and the new Edge backend exist. Backends are identified by their names, documented in the backend descriptions below.

## wxWEBVIEW_BACKEND_IE (MSW)

The IE backend uses Microsoft's WebBrowser control, which depends the locally installed version of Internet Explorer. By default this backend emulates Internet Explorer 7. This can be changed with a registry setting by wxWebViewIE::MSWSetEmulationLevel() see this article for more information.

This backend has full support for custom schemes and virtual file systems.

The predefined `wxWebViewBackendIE` constant contains the name of this backend and can be used to explicitly select it when using wxWebView::New().

Note
  If you plan to display any modern web content you should consider using wxWEBVIEW_BACKEND_EDGE (MSW), as Internet Explorer is not supported anymore by Microsoft.

## wxWEBVIEW_BACKEND_EDGE (MSW)

The Edge backend uses Microsoft's Edge WebView2. It is available for Windows 7 and newer.

This backend does not support custom schemes and virtual file systems.

This backend is not enabled by default, to build it follow these steps:

- Visual Studio 2015 or newer, or GCC/Clang with c++11 is required
- With CMake just enable `wxUSE_WEBVIEW_EDGE`
- When not using CMake:
  - Download the WebView2 SDK nuget package (Version 1.0.705.50 or newer)
  - Extract the package (it's a zip archive) to `wxWidgets/3rdparty/webview2` (you should have `3rdparty/webview2/build/native/include/WebView2.h` file after unpacking it)
  - Enable `wxUSE_WEBVIEW_EDGE` in `setup.h`
- Build wxWidgets webview library
- Copy `WebView2Loader.dll` from the subdirectory corresponding to the architecture used (x86 or x64) of `wxWidgets/3rdparty/webview2/build/` to your applications executable
- At runtime you can use wxWebView::IsBackendAvailable() to check if the backend can be used (it will be available if `WebView2Loader.dll` can be loaded and Edge (Chromium) is installed)
- Make sure to add a note about using the WebView2 SDK to your application documentation, as required by its licence
- With Visual Studio 2019 or newer `wxUSE_WEBVIEW_EDGE_STATIC` can be used to static link the loader and remove the dependency on `WebView2Loader.dll` at runtime.

If enabled and available at runtime Edge will be selected as the default backend. If you require the IE backend use `wxWebViewBackendIE` when using wxWebView::New().

If your application should use a fixed version of the WebView2 runtime you must use wxWebViewEdge::MSWSetBrowserExecutableDir() to specify its usage before using the Edge backend.

The predefined `wxWebViewBackendEdge` constant contains the name of this backend.

## wxWEBVIEW_WEBKIT (GTK)

Under GTK the WebKit backend uses WebKitGTK+. The current minimum version required is 1.3.1 which ships by default with Ubuntu Natty and Debian Wheezy and has the package name libwebkitgtk-dev.

Custom schemes and virtual files systems are supported under this backend, however embedded resources such as images and stylesheets are currently loaded using the data:// scheme.

The predefined `wxWebViewBackendWebKit` constant contains the name of this backend.

## wxWEBVIEW_WEBKIT2 (GTK3)

Under GTK3 the WebKit2 version of WebKitGTK+ is used. In Ubuntu the required package name is libwebkit2gtk-4.0-dev and under Fedora it is webkitgtk4-devel.

All features are supported except for clearing and enabling / disabling the history.

The predefined `wxWebViewBackendWebKit` constant contains the name of this backend.

## wxWEBVIEW_WEBKIT (macOS)

The macOS WebKit backend uses Apple's WKWebView class.

This backend has full support for custom schemes and virtual file systems on macOS 10.13+. In order to use handlers two-step creation has to be used and RegisterHandler() has to be called before Create().

Starting with macOS 10.11 and iOS 9 an application cannot create unsecure connections (this includes HTTP and unverified HTTPS). You have to include additional fields in your Info.plist to enable such connections. For further details see the documentation on NSAppTransportSecurity here

The predefined `wxWebViewBackendWebKit` constant contains the name of this backend.

# Asynchronous Notifications

Many of the methods in wxWebView are asynchronous, i.e. they return immediately and perform their work in the background. This includes functions such as LoadURL() and Reload(). To receive notification of the progress and completion of these functions you need to handle the events that are provided. Specifically `wxEVT_WEBVIEW_LOADED` notifies when the page or a sub-frame has finished loading and `wxEVT_WEBVIEW_ERROR` notifies that an error has occurred.

# Virtual File Systems and Custom Schemes

wxWebView supports the registering of custom scheme handlers, for example `file` or `http`. To do this create a new class which inherits from wxWebViewHandler, where wxWebHandler::GetFile() returns a pointer to a wxFSFile which represents the given url. You can then register your handler with RegisterHandler() it will be called for all pages and resources.

wxWebViewFSHandler is provided to access the virtual file system encapsulated by wxFileSystem. The wxMemoryFSHandler documentation gives an example of how this may be used.

wxWebViewArchiveHandler is provided to allow the navigation of pages inside a zip archive. It supports paths of the form: `scheme:///C`:/example/docs.zip;protocol=zip/main.htm

## Events emitted by this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxWebViewEvent& event)

Event macros for events emitted by this class:

- EVT_WEBVIEW_NAVIGATING(id, func):
  Process a `wxEVT_WEBVIEW_NAVIGATING` event, generated before trying to get a resource. This event may be vetoed to prevent navigating to this resource. Note that if the displayed HTML document has several frames, one such event will be generated per frame.
- EVT_WEBVIEW_NAVIGATED(id, func):
  Process a `wxEVT_WEBVIEW_NAVIGATED` event generated after it was confirmed that a resource would be requested. This event may not be vetoed. Note that if the displayed HTML document has several frames, one such event will be generated per frame.
- EVT_WEBVIEW_LOADED(id, func):
  Process a `wxEVT_WEBVIEW_LOADED` event generated when the document is fully loaded and displayed. Note that if the displayed HTML document has several frames, one such event will be generated per frame.
- EVT_WEBVIEW_ERROR(id, func):
  Process a `wxEVT_WEBVIEW_ERROR` event generated when a navigation error occurs. The integer associated with this event will be a wxWebNavigationError item. The string associated with this event may contain a backend-specific more precise error message/code.
- EVT_WEBVIEW_NEWWINDOW(id, func):
  Process a `wxEVT_WEBVIEW_NEWWINDOW` event, generated when a new window is created. You must handle this event if you want anything to happen, for example to load the page in a new window or tab.
- EVT_WEBVIEW_TITLE_CHANGED(id, func):
  Process a `wxEVT_WEBVIEW_TITLE_CHANGED` event, generated when the page title changes. Use GetString to get the title.
- EVT_WEBVIEW_FULLSCREEN_CHANGED(id, func):
  Process a `wxEVT_WEBVIEW_FULLSCREEN_CHANGED` event, generated when the page wants to enter or leave fullscreen. Use GetInt to get the status. Not implemented for the IE backend and is only available in wxWidgets 3.1.5 or later.
- EVT_WEBVIEW_SCRIPT_MESSAGE_RECEIVED(id, func):
  Process a `wxEVT_WEBVIEW_SCRIPT_MESSAGE_RECEIVED` event only available in wxWidgets 3.1.5 or later. For usage details see AddScriptMessageHandler().
- wxEVT_WEBVIEW_SCRIPT_RESULT(id, func):
  Process a `wxEVT_WEBVIEW_SCRIPT_RESULT` event only available in wxWidgets 3.1.6 or later. For usage details see RunScriptAsync().

## Member Function Documentation

## ◆ AddScriptMessageHandler()

virtual bool wxWebView::AddScriptMessageHandler | ( | const wxString & | name | ) |
| virtual

Add a script message handler with the given name.

To use the script message handler from javascript use ``window`.<name>.postMessage(<messageBody>)` where `<name>` corresponds the value of the name parameter. The `<messageBody>` will be available to the application via a `wxEVT_WEBVIEW_SCRIPT_MESSAGE_RECEIVED` event.

Sample C++ code receiving a script message:

// Install message handler with the name wx_msg
m_webView->AddScriptMessageHandler('wx_msg');
// Bind handler
m_webView->Bind(wxEVT_WEBVIEW_SCRIPT_MESSAGE_RECEIVED, [](wxWebViewEvent& evt) {
wxLogMessage("Script message received; value = %s, handler = %s", evt.GetString(), evt.GetMessageHandler());
});
wxCommandEvent::GetString
wxString GetString() const
Returns item string for a listbox or choice selection event.
wxWebViewEvent
A navigation event holds information about events associated with wxWebView objects.
Definition: webview.h:1330
wxWebViewEvent::GetMessageHandler
const wxString & GetMessageHandler() const
Get the name of the script handler.
wxLogMessage
void wxLogMessage(const char *formatString,...)
For all normal, informational messages.
wxEVT_WEBVIEW_SCRIPT_MESSAGE_RECEIVED
wxEventType wxEVT_WEBVIEW_SCRIPT_MESSAGE_RECEIVED
Definition: webview.h:1383

Sample javascript sending a script message:

// Send sample message body
window.wx_msg.postMessage('This is a message body');

Parameters

  name | Name of the message handler that can be used from javascript

Returns
  true if the handler could be added, false if it could not be added.

## ◆ RunScript()

virtual bool wxWebView::RunScript | ( | const wxString & | javascript,
|  | wxString * | output = `NULL`
| ) |  | const
| pure virtual

Runs the given JavaScript code.

Note
  Because of various potential issues it's recommended to use RunScriptAsync() instead of this method. This is especially true if you plan to run code from a webview event and will also prevent unintended side effects on the UI outside of the webview.

JavaScript code is executed inside the browser control and has full access to DOM and other browser-provided functionality. For example, this code

webview->RunScript("document.write('Hello from wxWidgets!')");

will replace the current page contents with the provided string.

If output is non-null, it is filled with the result of executing this code on success, e.g. a JavaScript value such as a string, a number (integer or floating point), a boolean or JSON representation for non-primitive types such as arrays and objects. For example:

wxString result;
if ( webview->RunScript
(
"document.getElementById('some_id').innerHTML",
&result
) )
{
... result contains the contents of the given element ...
}
//else: the element with this ID probably doesn't exist.
wxString
String class for passing textual data to or receiving it from wxWidgets.
Definition: string.h:315

This function has a few platform-specific limitations:

- When using WebKit v1 in wxGTK2, retrieving the result of JavaScript execution is unsupported and this function will always return false if output is non-null to indicate this. This functionality is fully supported when using WebKit v2 or later in wxGTK3.
- When using WebKit under macOS, code execution is limited to at most 10MiB of memory and 10 seconds of execution time.
- When using IE backend under MSW, scripts can only be executed when the current page is fully loaded (i.e. `wxEVT_WEBVIEW_LOADED` event was received). A script tag inside the page HTML is required in order to run JavaScript.

Also notice that under MSW converting JavaScript objects to JSON is not supported in the default emulation mode. wxWebView implements its own object-to-JSON conversion as a fallback for this case, however it is not as full-featured, well-tested or performing as the implementation of this functionality in the browser control itself, so it is recommended to use MSWSetEmulationLevel() to change emulation level to a more modern one in which JSON conversion is done by the control itself.

Parameters

  javascript | JavaScript code to execute.
  output | Pointer to a string to be filled with the result value or NULL if it is not needed. This parameter is new since wxWidgets version 3.1.1.

Returns
  true if there is a result, false if there is an error.

See also
  RunScriptAsync()

## ◆ RunScriptAsync()

virtual void wxWebView::RunScriptAsync | ( | const wxString & | javascript,
|  | void * | clientData = `NULL`
| ) |  | const
| virtual

Runs the given JavaScript code asynchronously and returns the result via a `wxEVT_WEBVIEW_SCRIPT_RESULT`.

The script result value can be retrieved via wxWebViewEvent::GetString(). If the execution fails wxWebViewEvent::IsError() will return true. In this case additional script execution error information maybe available via wxWebViewEvent::GetString().

Parameters

  javascript | JavaScript code to execute.
  clientData | Arbirary pointer to data that can be retrieved from the result event.

Note
  The IE backend does not support async script execution.

Since
  3.1.6
