Members

COREWEBVIEW2_MATRIX_4X4

Matrix that represents a 3D transform.

typedef COREWEBVIEW2_MATRIX_4X4

This transform is used to calculate correct coordinates when calling CreateCoreWebView2PointerInfoFromPointerId. This is equivalent to a D2D1_MATRIX_4X4_F

COREWEBVIEW2_MEMORY_USAGE_TARGET_LEVEL

enum COREWEBVIEW2_MEMORY_USAGE_TARGET_LEVEL

Values Descriptions
COREWEBVIEW2_MEMORY_USAGE_TARGET_LEVEL_NORMAL Specifies normal memory usage target level.
COREWEBVIEW2_MEMORY_USAGE_TARGET_LEVEL_LOW Specifies low memory usage target level.

Specifies memory usage target level of WebView.

COREWEBVIEW2_NAVIGATION_KIND

enum COREWEBVIEW2_NAVIGATION_KIND

Values Descriptions
COREWEBVIEW2_NAVIGATION_KIND_RELOAD A navigation caused by CoreWebView2.Reload(), location.reload(), the end user using F5 or other UX, or other reload mechanisms to reload the current document without modifying the navigation history.
COREWEBVIEW2_NAVIGATION_KIND_BACK_OR_FORWARD A navigation back or forward to a different entry in the session navigation history, like via CoreWebView2.Back(), location.back(), the end user pressing Alt+Left or other UX, or other mechanisms to navigate back or forward in the current session navigation history.
COREWEBVIEW2_NAVIGATION_KIND_NEW_DOCUMENT A navigation to another document, which can be caused by CoreWebView2.Navigate(), window.location.href = ..., or other WebView2 or DOM APIs that navigate to a new URI.

Specifies the navigation kind of each navigation.

COREWEBVIEW2_TEXTURE_STREAM_ERROR_KIND

enum COREWEBVIEW2_TEXTURE_STREAM_ERROR_KIND

Values Descriptions
COREWEBVIEW2_TEXTURE_STREAM_ERROR_NO_VIDEO_TRACK_STARTED CreateTexture/PresentTexture and so on should return failed HRESULT if the texture stream is in the stopped state rather than using the error event.
COREWEBVIEW2_TEXTURE_STREAM_ERROR_TEXTURE_ERROR The texture already has been removed using CloseTexture.
COREWEBVIEW2_TEXTURE_STREAM_ERROR_TEXTURE_IN_USE The texture to be presented is already in use for rendering.

Kinds of errors that can be reported by the ICoreWebView2ExperimentalTextureStream ErrorReceived event.

COREWEBVIEW2_UPDATE_RUNTIME_STATUS

enum COREWEBVIEW2_UPDATE_RUNTIME_STATUS

Values Descriptions
COREWEBVIEW2_UPDATE_RUNTIME_STATUS_LATEST_VERSION_INSTALLED Latest version of Edge WebView2 Runtime is installed.
COREWEBVIEW2_UPDATE_RUNTIME_STATUS_UPDATE_ALREADY_RUNNING Edge WebView2 Runtime update is already running, which could be triggered by auto update or by other UpdateRuntime request from some app.
COREWEBVIEW2_UPDATE_RUNTIME_STATUS_BLOCKED_BY_POLICY Edge WebView2 Runtime update is blocked by group policy.
COREWEBVIEW2_UPDATE_RUNTIME_STATUS_FAILED Edge WebView2 Runtime update failed.

Status of UpdateRuntime operation result.

COREWEBVIEW2_WEB_RESOURCE_REQUEST_SOURCE_KINDS

enum COREWEBVIEW2_WEB_RESOURCE_REQUEST_SOURCE_KINDS

Values Descriptions
COREWEBVIEW2_WEB_RESOURCE_REQUEST_SOURCE_KINDS_NONE
COREWEBVIEW2_WEB_RESOURCE_REQUEST_SOURCE_KINDS_DOCUMENT Indicates that web resource is requested from main page including dedicated workers and iframes.
COREWEBVIEW2_WEB_RESOURCE_REQUEST_SOURCE_KINDS_SHARED_WORKER Indicates that web resource is requested from shared worker.
COREWEBVIEW2_WEB_RESOURCE_REQUEST_SOURCE_KINDS_SERVICE_WORKER Indicates that web resource is requested from service worker.
COREWEBVIEW2_WEB_RESOURCE_REQUEST_SOURCE_KINDS_ALL Indicates that web resource is requested from any supported source.

Specifies the source of WebResourceRequested event.
