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
| 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
| 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
| 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
| 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
| 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.
