Host object proxies are promises and will resolve to an object representing the host object. Only the COM visible objects/properties/methods can be accessed from script. The app can control which part of .NET objects are exposed using <see cref="T:System.Runtime.InteropServices.ComVisibleAttribute"/>. JavaScript code in the WebView will be able to access appObject as following and then access attributes and methods of appObject. Note that while simple types, <c>IDispatch</c> and array are supported, and <c>IUnknown</c> objects that also implement <c>IDispatch</c> are treated as <c>IDispatch</c>, generic <c>IUnknown</c>, <c>VT_DECIMAL</c>, or <c>VT_RECORD</c> variant is not supported. Remote JavaScript objects like callback functions are represented as an <c>VT_DISPATCH</c> VARIANT with the object implementing <c>IDispatch</c>. The JavaScript callback method may be invoked using DISPID_VALUE for the DISPID. Such callback method invocations will return immediately and will not wait for the JavaScript function to run and so will not provide the return value of the JavaScript function. Nested arrays are supported up to a depth of 3. Arrays of by reference types are not supported. <c>VT_EMPTY</c> and <c>VT_NULL</c> are mapped into JavaScript as <c>null</c>. In JavaScript <c>null</c> and <c>undefined</c> are mapped to <c>VT_EMPTY</c>. Additionally, all host objects are exposed as <c>window.chrome.webview.hostObjects.sync.{name}</c>. Here the host objects are exposed as synchronous host object proxies. These are not promises and calls to functions or property access synchronously block running script waiting to communicate cross process for the host code to run. Accordingly this can result in reliability issues and it is recommended that you use the promise based asynchronous <c>window.chrome.webview.hostObjects.{name}</c> API described above. Synchronous host object proxies and asynchronous host object proxies can both proxy the same host object. Remote changes made by one proxy will be reflected in any other proxy of that same host object whether the other proxies and synchronous or asynchronous. While JavaScript is blocked on a synchronous call to native code, that native code is unable to call back to JavaScript. Attempts to do so will fail with <c>HRESULT_FROM_WIN32(ERROR_POSSIBLE_DEADLOCK)</c>. Host object proxies are JavaScript Proxy objects that intercept all property get, property set, and method invocations. Properties or methods that are a part of the Function or Object prototype are run locally. Additionally any property or method in the array <c>chrome.webview.hostObjects.options.forceLocalProperties</c> will also be run locally. This defaults to including optional methods that have meaning in JavaScript like <c>toJSON</c> and <c>Symbol.toPrimitive</c>. You can add more to this array as required. There's a method <c>chrome.webview.hostObjects.cleanupSome</c> that will best effort garbage collect host object proxies. The <c>chrome.webview.hostObjects.options</c> object provides the ability to change some functionality of host objects. <list type="table"> <listheader> <term>Options property</term> <description>Details</description> </listheader> <item> <term><c>forceLocalProperties</c></term> <description> This is an array of host object property names that will be run locally, instead of being called on the native host object. This defaults to <c>then</c>, <c>toJSON</c>, <c>Symbol.toString</c>, and <c>Symbol.toPrimitive</c>. You can add other properties to specify that they should be run locally on the JavaScript host object proxy. </description> </item> <item> <term><c>log</c></term> <description> This is a callback that will be called with debug information. For example, you can set this to <c>console.log.bind(console)</c> to have it print debug information to the console to help when troubleshooting host object usage. By default this is null. </description> </item> <item> <term><c>shouldSerializeDates</c></term> <description> By default this is false, and JavaScript Date objects will be sent to host objects as a string using <c>JSON.stringify</c>. You can set this property to true to have Date objects properly serialize as a <c>System.DateTime</c> when sending to the .NET host object, and have <c>System.DateTime</c> properties and return values create a JavaScript <c>Date</c> object. </description> </item> <item> <term><c>defaultSyncProxy</c></term> <description> When calling a method on a synchronous proxy, the result should also be a synchronous proxy. But in some cases, the sync/async context is lost (for example, when providing to native code a reference to a function, and then calling that function in native code). In these cases, the proxy will be asynchronous, unless this property is set. </description> </item> <item> <term><c>forceAsyncMethodMatches</c></term> <description> This is an array of regular expressions. When calling a method on a synchronous proxy, the method call will be performed asynchronously if the method name matches a string or regular expression in this array. Setting this value to <c>Async</c> will make any method that ends with Async be an asynchronous method call. If an async method doesn't match here and isn't forced to be asynchronous, the method will be invoked synchronously, blocking execution of the calling JavaScript and then returning the resolution of the promise, rather than returning a promise. </description> </item> <item> <term><c>ignoreMemberNotFoundError</c></term> <description> By default, an exception is thrown when attempting to get the value of a proxy property that doesn't exist on the corresponding native class. Setting this property to <c>true</c> switches the behavior to match Chakra WinRT projection (and general JavaScript) behavior of returning <c>undefined</c> with no error. </description> </item> </list> Host object proxies additionally have the following methods: <list type="table"> <listheader> <term>Method name</term> <description>Details</description> </listheader> <item> <term><c>applyHostFunction</c>, <c>getHostProperty</c>, <c>setHostProperty</c></term> <description> Perform a method invocation, property get, or property set on the host object. You can use these to explicitly force a method or property to run remotely if there is a conflicting local method or property. For instance, <c>proxy.toString()</c> will run the local <c>toString</c> method on the proxy object. But <c>proxy.applyHostFunction('toString')</c> runs <c>toString</c> on the host proxied object instead. </description> </item> <item> <term><c>getLocalProperty</c>, <c>setLocalProperty</c></term> <description> Perform property get, or property set locally. You can use these methods to force getting or setting a property on the host object proxy itself rather than on the host object it represents. For instance, <c>proxy.unknownProperty</c> will get the property named <c>unknownProperty</c> from the host proxied object. But <c>proxy.getLocalProperty('unknownProperty')</c> will get the value of the property <c>unknownProperty</c> on the proxy object itself. </description> </item> <item> <term><c>addEventListener</c></term> <description> This method only exists on proxies for .NET objects. Bind the JavaScript handler to the C# event, so that the JavaScript handler can be called through the C# event. For example, <c>chrome.webview.hostObjects.sample.addEventListener('TestEvent', () => { alert('Invoked from remote');});</c> bind an anonymous JavaScript function to a C# event called 'TestEvent'. When calling <c>TestEvent?.Invoke()</c> on C# side, the JavaScript function that was just bound will be called asynchronously. It allows adding more than one handler for an event, but if the handler is already in the list of event handler, it will not be added a second time. If the host object cannot find the event with the name passed in by the <c>addEventListener</c> function or it is no public or its return type is not void, an exception will be thrown. If the count and type of C# event's parameters do not match the count and type of JavaScript handler, invoke <c>addEventListener</c> will be successful but an exception will be passed to JavaScript when invoke the event on C# side. If the host object has defined <c>addEventListener</c> function, use the defined function rather than the additionally <c>addEventListener</c> function. </description> </item> <item> <term><c>removeEventListener</c></term> <description> This method only exists on proxies for .NET objects. Removes a handler previously bound with <c>addEventListener()</c>. If the handler does not exist in the list of event handler, nothing will happen. If the host object cannot find the event with the name passed in by the <c>removeEventListener</c> function or it is no public, an exception will be thrown. If the host object has defined <c>removeEventListener</c> function, use the defined function rather than the additionally <c>removeEventListener</c> function. </description> </item> <item> <term><c>sync</c></term> <description> Asynchronous host object proxies expose a sync method which returns a promise for a synchronous host object proxy for the same host object. For example, <c>chrome.webview.hostObjects.sample.methodCall()</c> returns an asynchronous host object proxy. You can use the <c>sync</c> method to obtain a synchronous host object proxy instead: <c>const syncProxy = await chrome.webview.hostObjects.sample.methodCall().sync()</c> </description> </item> <item> <term><c>async</c></term> <description> Synchronous host object proxies expose an async method which blocks and returns an asynchronous host object proxy for the same host object. For example, <c>chrome.webview.hostObjects.sync.sample.methodCall()</c> returns a synchronous host object proxy. Calling the <c>async</c> method on this blocks and then returns an asynchronous host object proxy for the same host object: <c>const asyncProxy = chrome.webview.hostObjects.sync.sample.methodCall().async()</c> </description> </item> <item> <term><c>then</c></term> <description> Asynchronous host object proxies have a then method. This allows them to be awaitable. <c>then</c> will return a promise that resolves with a representation of the host object. If the proxy represents a JavaScript literal then a copy of that is returned locally. If the proxy represents a function then a non-awaitable proxy is returned. If the proxy represents a JavaScript object with a mix of literal properties and function properties, then the a copy of the object is returned with some properties as host object proxies. </description> </item> <item> <term><c>cancelPromise</c></term> <description> This method attempts to cancel the fulfillment of a promised value. If the promise hasn't already been fulfilled and cancelation is supported, the promise will get rejected. <c>cancelPromise</c> supports cancelation of IAsyncOperation and IAsyncAction methods. If the promise is successfully canceled, then calling await on the promise will throw. For example, <c>chrome.webview.hostObjects.cancelPromise(promise); await promise;</c> will throw with "Promise Canceled". Once a promise has been canceled, a subsequent cancel on the same promise will throw an exception as well. </description> </item> </list> All other property and method invocations (other than the above Remote object proxy methods, <c>forceLocalProperties</c> list, and properties on Function and Object prototypes) are run remotely. Asynchronous host object proxies return a promise representing asynchronous completion of remotely invoking the method, or getting the property. The promise resolves after the remote operations complete and the promises resolve to the resulting value of the operation. Synchronous host object proxies work similarly but block JavaScript execution and wait for the remote operation to complete. Setting a property on an asynchronous host object proxy works slightly differently. The set returns immediately and the return value is the value that will be set. This is a requirement of the JavaScript Proxy object. If you need to asynchronously wait for the property set to complete, use the <c>setHostProperty</c> method which returns a promise as described above. Synchronous object property set property synchronously blocks until the property is set. Exposing host objects to script has security risk. Please follow [best practices](/microsoft-edge/webview2/concepts/security). </remarks> <example> To create a [IDispatch](/windows/win32/api/oaidl/nn-oaidl-idispatch) implementing class in C# use the following attributes on each class you intend to expose. <code> // Bridge and BridgeAnotherClass are C# classes that implement IDispatch and works with AddHostObjectToScript. [ClassInterface(ClassInterfaceType.AutoDual)] [ComVisible(true)] public class BridgeAnotherClass { // Sample property. public string Prop { get; set; } = "Example"; } [ClassInterface(ClassInterfaceType.AutoDual)] [ComVisible(true)] public class Bridge { public string Func(string param) { return "Example: " + param; } public BridgeAnotherClass AnotherObject { get; set; } = new BridgeAnotherClass(); // Sample indexed property. [System.Runtime.CompilerServices.IndexerName("Items")] public string this[int index] { get { return m_dictionary[index]; } set { m_dictionary[index] = value; } } private Dictionary<int, string> m_dictionary = new Dictionary<int, string>(); } </code> Then add instances of those classes via <see cref="M:Microsoft.Web.WebView2.Core.CoreWebView2.AddHostObjectToScript(System.String,System.Object)"/>: <code> webView.CoreWebView2.AddHostObjectToScript("bridge", new Bridge()); </code> And then in script you can call the methods, and access those properties of the objects added via <see cref="M:Microsoft.Web.WebView2.Core.CoreWebView2.AddHostObjectToScript(System.String,System.Object)"/>.

Otherwise, the API throws COMException with error code of <c>HRESULT_FROM_WIN32(ERROR_INVALID_STATE)</c>. Suspending is similar to putting a tab to sleep in the Edge browser. Suspending pauses WebView script timers and animations, minimizes CPU usage for the associated browser renderer process and allows the operating system to reuse the memory that was used by the renderer process for other processes. Note that Suspend is best effort and considered completed successfully once the request is sent to browser renderer process. If there is a running script, the script will continue to run and the renderer process will be suspended after that script is done.

In those situations, the result of the async task is false. The WebView will be automatically resumed when it becomes visible.

WebView will be automatically resumed when it becomes visible. </remarks> <example> :::code language="csharp" source="../code/sample/SampleApps/WebView2WpfBrowser/MainWindow.xaml.cs" id="Resume"::: </example> </member> <member name="M:Microsoft.Web.WebView2.Core.CoreWebView2.SetVirtualHostNameToFolderMapping(System.String,System.String,Microsoft.Web.WebView2.Core.CoreWebView2HostResourceAccessKind)"> <summary> Sets a mapping between a virtual host name and a folder path to make available to web sites via that host name. </summary> <param name="hostName">A virtual host name.</param> <param name="folderPath">A folder path name to be mapped to the virtual host name. The length must not exceed the Windows MAX_PATH limit.</param> <param name="accessKind">The level of access to resources under the virtual host from other sites.</param> <remarks> <para> After setting the mapping, documents loaded in the WebView can use HTTP or HTTPS URLs at the specified host name specified by <c>hostName</c> to access files in the local folder specified by <c>folderPath</c>. This mapping applies to both top-level document and iframe navigations as well as subresource references from a document. This also applies to dedicated and shared worker scripts but does not apply to service worker scripts. Due to a current implementation limitation, media files accessed using virtual host name can be very slow to load. As the resource loaders for the current page might have already been created and running, changes to the mapping might not be applied to the current page and a reload of the page is needed to apply the new mapping. Both absolute and relative paths are supported for <c>folderPath</c>. Relative paths are interpreted as relative to the folder where the exe of the app is in. </para> <para> For example, after calling <c>SetVirtualHostNameToFolderMapping("appassets.example", "assets", CoreWebView2HostResourceAccessKind.Deny);</c>, navigating to <c>https://appassets.example/my-local-file.html</c> will show content from my-local-file.html in the assets subfolder located on disk under the same path as the app's executable file. DOM elements that want to reference local files will have their host reference virtual host in the source. If there are multiple folders being used, define one unique virtual host per folder. </para> <para> You should typically choose virtual host names that are never used by real sites. If you own a domain such as <c>example.com</c>, another option is to use a subdomain reserved for the app (like <c>my-app.example.com</c>). </para> <para> [RFC 6761](https://tools.ietf.org/html/rfc6761) has reserved several special-use domain names that are guaranteed to not be used by real sites (for example, <c>.example</c>, <c>.test</c>, and <c>.invalid</c>). </para> <para> Note that using <c>.local</c> as the top-level domain name will work but can cause a delay during navigations. You should avoid using <c>.local</c> if you can. </para> <para> Apps should use distinct domain names when mapping folder from different sources that should be isolated from each other. For instance, the app might use app-file.example for files that ship as part of the app, and book1.example might be used for files containing books from a less trusted source that were previously downloaded and saved to the disk by the app. </para> <para> The host name used in the APIs is canonicalized using Chromium's host name parsing logic before being used internally. For more information see [HTML5 2.6 URLs](https://dev.w3.org/html5/spec-LC/urls.html). </para> <para> All host names that are canonicalized to the same string are considered identical. For example, <c>EXAMPLE.COM</c> and <c>example.com</c> are treated as the same host name. An international host name and its Punycode-encoded host name are considered the same host name. There is no DNS resolution for host name and the trailing '.' is not normalized as part of canonicalization. </para> <para> Therefore <c>example.com</c> and <c>example.com.</c> are treated as different host names. Similarly, <c>virtual-host-name</c> and <c>virtual-host-name.example.com</c> are treated as different host names even if the machine has a DNS suffix of <c>example.com</c>. </para> <para> Specify the minimal cross-origin access necessary to run the app. If there is not a need to access local resources from other origins, use <see cref="F:Microsoft.Web.WebView2.Core.CoreWebView2HostResourceAccessKind.Deny"/>. </para> </remarks> <example> <code> webView.CoreWebView2.SetVirtualHostNameToFolderMapping( "appassets.example", "assets", CoreWebView2HostResourceAccessKind.DenyCors); webView.Source = new Uri("https://appassets.example/index.html"); </code> This in an example on how to embed a local image.

The script code should call <c>chrome.webview.releaseBuffer</c> with the shared buffer as the parameter to release underlying resources as soon as it does not need access to the shared buffer any more. The application can post the same shared buffer object to multiple web pages or iframes, or post to the same web page or iframe multiple times.

The underlying shared memory will be released when all the views are released. Sharing a buffer to script has security risk. You should only share buffer with trusted site.

Scripts will not be impacted and continue to run. This is useful for inactive apps that still want to run scripts and/or keep network connections alive and therefore could not call <see cref="M:Microsoft.Web.WebView2.Core.CoreWebView2.TrySuspendAsync"/> and <see cref="M:Microsoft.Web.WebView2.Core.CoreWebView2.Resume"/> to reduce memory consumption. These apps can set memory usage target level to <see cref="F:Microsoft.Web.WebView2.Core.CoreWebView2MemoryUsageTargetLevel.Low"/> when the app becomes inactive, and set back to <see cref="F:Microsoft.Web.WebView2.Core.CoreWebView2MemoryUsageTargetLevel.Normal"/> when the app becomes active. It is not necessary to set CoreWebView2Controller's IsVisible property to false when setting the property. It is a best effort operation to change memory usage level, and the API will return before the operation completes. Setting the level to <see cref="F:Microsoft.Web.WebView2.Core.CoreWebView2MemoryUsageTargetLevel.Low"/> could potentially cause memory for some WebView browser processes to be swapped out to disk in some circumstances. It is a best effort to reduce memory usage as much as possible. If a script runs after its related memory has been swapped out, the memory will be swapped back in to ensure the script can still run, but performance might be impacted. Therefore, the app should set the level back to <see cref="F:Microsoft.Web.WebView2.Core.CoreWebView2MemoryUsageTargetLevel.Normal"/> when the app becomes active again. Setting memory usage target level back to normal will not happen automatically. An app should choose to use either the combination of <see cref="M:Microsoft.Web.WebView2.Core.CoreWebView2.TrySuspendAsync"/> and <see cref="M:Microsoft.Web.WebView2.Core.CoreWebView2.Resume"/> or the combination of setting MemoryUsageTargetLevel to <see cref="F:Microsoft.Web.WebView2.Core.CoreWebView2MemoryUsageTargetLevel.Low"/> and <see cref="F:Microsoft.Web.WebView2.Core.CoreWebView2MemoryUsageTargetLevel.Normal"/>.

When a specified zoom factor is out of that range, it is normalized to be within the range, and a <see cref="E:Microsoft.Web.WebView2.Core.CoreWebView2Controller.ZoomFactorChanged"/> event is raised for the real applied zoom factor.

Close is implicitly run when the <see cref="T:Microsoft.Web.WebView2.Core.CoreWebView2Controller"/> loses the final reference and is destructed. But it is best practice to explicitly run Close to avoid any accidental cycle of references between the WebView and the app code. Specifically, if you capture a reference to the WebView in an event handler you create a reference cycle between the WebView and the event handler. Run Close to break the cycle by releasing all event handlers. But to avoid the situation, it is best to both explicitly run Close on the WebView and to not capture a reference to the WebView to ensure the WebView is cleaned up correctly.

Web pages with defined and opaque background properties that span the page will obscure the `DefaultBackgroundColor` and display normally. The default value for this property is white to resemble the native browser experience. Currently this API only supports opaque colors and transparency. It will fail for colors with alpha values that don't equal 0 or 255 ie. translucent colors are not supported. It also does not support transparency on Windows 7. On Windows 7, setting DefaultBackgroundColor to a Color with an Alpha value other than 255 will result in failure. On any OS above Win7, choosing a transparent color will result in showing hosting app content. This means webpages without explicit background properties defined will render web content over hosting app content. This property may also be set via the `WEBVIEW2_DEFAULT_BACKGROUND_COLOR` environment variable. There is a known issue with background color where just setting the color by property can still leave the app with a white flicker before the `DefaultBackgroundColor` property takes effect. Setting the color via environment variable solves this issue. The value must be a hex value that can optionally prepend a 0x. The value must account for the alpha value which is represented by the first 2 digits. So any hex value fewer than 8 digits will assume a prepended 00 to the hex value and result in a transparent color. `DefaultBackgroundColor` will return the result of this environment variable even if it has not been set directly. This environment variable can only set the `DefaultBackgroundColor` once. Subsequent updates to background color must be done by setting the property. </remarks> <example> :::code language="csharp" source="../code/sample/SampleApps/WebView2WpfBrowser/MainWindow.xaml.cs" id="DefaultBackgroundColor"::: </example> </member> <member name="P:Microsoft.Web.WebView2.Core.CoreWebView2Controller.RasterizationScale"> <summary> Gets or sets the WebView rasterization scale. </summary> <remarks> The rasterization scale is the combination of the monitor DPI scale and text scaling set by the user.

When the entire collection of WebView2Runtime processes for the browser process exit, all associated <see cref="T:Microsoft.Web.WebView2.Core.CoreWebView2Environment"/> objects receive the BrowserProcessExited event. Multiple processes sharing the same browser process need to coordinate their use of the shared user data folder to avoid race conditions and unnecessary waits.

In the case the browser process crashes, both BrowserProcessExited and <see cref="E:Microsoft.Web.WebView2.Core.CoreWebView2.ProcessFailed"/> events are raised, but the order is not guaranteed. These events are intended for different scenarios.

If the shared buffer is already closed, the API throws <see cref="T:System.Runtime.InteropServices.COMException"/> with error code of <c>RO_E_CLOSED</c>. The script code should call <c>chrome.webview.releaseBuffer</c> with the shared buffer as the parameter to release underlying resources as soon as it does not need access to the shared buffer any more. The application can post the same shared buffer object to multiple web pages or iframes, or post to the same web page or iframe multiple times. Each <c>PostSharedBufferToScript</c> will create a separate ArrayBuffer object with its own view of the memory and is separately released. The underlying shared memory will be released when all the views are released. Sharing a buffer to script has security risk. You should only share buffer with trusted site. If a buffer is shared to a untrusted site, possible sensitive information could be leaked. If a buffer is shared as modifiable by the script and the script modifies it in an unexpected way, it could result in corrupted data that might even crash the application. The example code shows how to send data to script for one time read only consumption. </remarks> <example> :::code language="csharp" source="../code/sample/SampleApps/WebView2WpfBrowser/MainWindow.xaml.cs" id="OneTimeShareBuffer"::: :::code language="csharp" source="../code/sample/SampleApps/WebView2WpfBrowser/assets/sharedBuffer.html" id="ShareBufferScriptCode_1"::: :::code language="csharp" source="../code/sample/SampleApps/WebView2WpfBrowser/assets/sharedBuffer.html" id="ShareBufferScriptCode_2"::: </example> </member> <member name="P:Microsoft.Web.WebView2.Core.CoreWebView2Frame.FrameId"> <summary> The unique identifier of the current frame.

Pinch-zoom, referred to as "Page Scale" zoom, is performed as a post-rendering step, it changes the page scale factor property and scales the surface the web page is rendered onto when user performs a pinch zooming action. It does not change the layout but rather changes the viewport and clips the web content, the content outside of the viewport isn't visible onscreen and users can't reach this content using mouse. This API only affects the Page Scale zoom and has no effect on the existing browser zoom properties (<see cref="P:Microsoft.Web.WebView2.Core.CoreWebView2Settings.IsZoomControlEnabled"/> and <see cref="P:Microsoft.Web.WebView2.Core.CoreWebView2Controller.ZoomFactor"/>) or other end user mechanisms for zooming. </remarks> <example> :::code language="csharp" source="../code/sample/SampleApps/WebView2WpfBrowser/MainWindow.xaml.cs" id="TogglePinchZoomEnabled"::: </example> </member> <member name="P:Microsoft.Web.WebView2.Core.CoreWebView2Settings.IsSwipeNavigationEnabled"> <summary> Determines whether the end user to use swiping gesture on touch input enabled devices to navigate in WebView2. </summary> <remarks> Swiping gesture navigation on touch screen includes: <list type="bullet"> <item><description> Swipe left/right (swipe horizontally) to navigate to previous/next page in navigation history. </description></item> <item><description> Pull to refresh (swipe vertically) the current page.

IsReputationCheckingRequired is used to control whether SmartScreen is enabled or not. SmartScreen is enabled or disabled for all CoreWebView2s using the same user data folder. If CoreWebView2Setting.IsReputationCheckingRequired is <c>true</c> for any CoreWebView2 using the same user data folder, then SmartScreen is enabled. If CoreWebView2Setting.IsReputationCheckingRequired is <c>false</c> for all CoreWebView2 using the same user data folder, then SmartScreen is disabled. When it is changed, the change will be applied to all WebViews using the same user data folder on the next navigation or download. If the newly created CoreWebview2 does not set SmartScreen to <c>false</c>, when navigating(Such as Navigate(), LoadDataUrl(), ExecuteScript(), etc.), the default value will be applied to all CoreWebview2 using the same user data folder. SmartScreen of WebView2 apps can be controlled by Windows system setting "SmartScreen for Microsoft Edge", specially, for WebView2 in Windows Store apps, SmartScreen is controlled by another Windows system setting "SmartScreen for Microsoft Store apps". When the Windows setting is enabled, the SmartScreen operates under the control of the `IsReputationCheckingRequired`. When the Windows setting is disabled, the SmartScreen will be disabled regardless of the `IsReputationCheckingRequired` value set in WebView2 apps. In other words, under this circumstance the value of `IsReputationCheckingRequired` will be saved but overridden by system setting. Upon re-enabling the Windows setting, the CoreWebview2 will reference the `IsReputationCheckingRequired` to determine the SmartScreen status. </remarks> </member> <member name="P:Microsoft.Web.WebView2.Core.CoreWebView2Settings.IsNonClientRegionSupportEnabled"> <summary> Use this property to get/set if nonclient region support is enabled </summary> </member> <member name="T:Microsoft.Web.WebView2.Core.CoreWebView2ServerCertificateErrorDetectedEventArgs"> <summary> Event args for the <see cref="E:Microsoft.Web.WebView2.Core.CoreWebView2.ServerCertificateErrorDetected"/> event. </summary> </member> <member name="P:Microsoft.Web.WebView2.Core.CoreWebView2ServerCertificateErrorDetectedEventArgs.ErrorStatus"> <summary> The TLS error code for the invalid certificate. </summary> </member> <member name="P:Microsoft.Web.WebView2.Core.CoreWebView2ServerCertificateErrorDetectedEventArgs.RequestUri"> <summary> URI associated with the request for the invalid certificate. </summary> </member> <member name="P:Microsoft.Web.WebView2.Core.CoreWebView2ServerCertificateErrorDetectedEventArgs.ServerCertificate"> <summary> Returns the <see cref="T:Microsoft.Web.WebView2.Core.CoreWebView2Certificate"/>. </summary> </member> <member name="P:Microsoft.Web.WebView2.Core.CoreWebView2ServerCertificateErrorDetectedEventArgs.Action"> <summary> The action of the server certificate error detection. </summary> <remarks> The default value is <see cref="F:Microsoft.Web.WebView2.Core.CoreWebView2ServerCertificateErrorAction.Default"/>. </remarks> </member> <member name="M:Microsoft.Web.WebView2.Core.CoreWebView2ServerCertificateErrorDetectedEventArgs.GetDeferral"> <summary> Gets a <see cref="T:Microsoft.Web.WebView2.Core.CoreWebView2Deferral"/> object. </summary> <remarks> Use this to <see cref="M:Microsoft.Web.WebView2.Core.CoreWebView2Deferral.Complete"/> the event at a later time. </remarks> </member> <member name="T:Microsoft.Web.WebView2.Core.CoreWebView2ScriptException"> <summary> This interface represents a JavaScript exception. </summary> </member> <member name="P:Microsoft.Web.WebView2.Core.CoreWebView2ScriptException.LineNumber"> <summary> The line number of the source where the exception occurred.

A CoreWebView2Controller.AcceleratorKeyPressed event is raised 1. WebView2 browser feature accelerator key handling 1. Web Content Handling: If the key combination isn't reserved for browser actions, the key event propagates to the web content, where JavaScript event listeners can capture and respond to it. If `Handled` property is set to <c>true</c> anywhere along the path, the event propagation stops, and web content will not receive the key and this prevents the WebView from performing the default action for this accelerator key. Otherwise the WebView will perform the default action for the accelerator key. </remarks> </member> <member name="P:Microsoft.Web.WebView2.Core.CoreWebView2AcceleratorKeyPressedEventArgs.IsBrowserAcceleratorKeyEnabled"> <summary> This `IsBrowserAcceleratorKeyEnabled` property allows developers to control whether the browser handles accelerator keys such as Ctrl+P or F3, etc. </summary> <remarks> The `CoreWebView2Settings.AreBrowserAcceleratorKeysEnabled` API is a convenient setting for developers to disable all the browser accelerator keys together. This setting also sets the default value for the `IsBrowserAcceleratorKeyEnabled` property. By default, `CoreWebView2Settings.AreBrowserAcceleratorKeysEnabled` is `TRUE` and `IsBrowserAcceleratorKeyEnabled` is `TRUE`. When developers change `CoreWebView2Settings.AreBrowserAcceleratorKeysEnabled` setting to `FALSE`, this will change default value for `IsBrowserAcceleratorKeyEnabled` to `FALSE`. If developers want specific keys to be handled by the browser after changing the `CoreWebView2Settings.AreBrowserAcceleratorKeysEnabled` setting to `FALSE`, they need to enable these keys by setting `IsBrowserAcceleratorKeyEnabled` to `TRUE`. The `CoreWebView2Controller.AcceleratorKeyPressed` event is raised any time an accelerator key is pressed, regardless of whether accelerator keys are enabled or not. This API will give the event arg higher priority over the `CoreWebView2Settings.AreBrowserAcceleratorKeysEnabled` setting when we handle the keys. With `IsBrowserAcceleratorKeyEnabled` property, if developers mark `IsBrowserAcceleratorKeyEnabled` as `FALSE`, the browser will skip the WebView2 browser feature accelerator key handling process, but the event propagation continues, and web content will receive the key combination. This property does not disable accelerator keys related to movement and text editing, such as: - Home, End, Page Up, and Page Down - Ctrl-X, Ctrl-C, Ctrl-V - Ctrl-A for Select All - Ctrl-Z for Undo </remarks> </member> </members> </doc> |
