Members

get_SystemCursorId

The current system cursor ID reported by the underlying rendering engine for WebView.

public HRESULT get_SystemCursorId(UINT32 * systemCursorId)

For example, most of the time, when the cursor is over text, this will return the int value for IDC_IBEAM. The systemCursorId is only valid if the rendering engine reports a default Windows cursor resource value. Navigate to LoadCursorW for more details. Otherwise, if custom CSS cursors are being used, this will return 0. To actually use systemCursorId in LoadCursor or LoadImage, MAKEINTRESOURCE must be called on it first.

C++

                        UINT32 cursorId;
                        wil::com_ptr<ICoreWebView2ExperimentalCompositionController2> compositionController2 =
                            m_controller.query<ICoreWebView2ExperimentalCompositionController2>();
                        CHECK_FAILURE(compositionController2->get_SystemCursorId(&cursorId));
                        cursor = ::LoadCursor(nullptr, MAKEINTRESOURCE(cursorId));
                        if (cursor == nullptr)
                        {
                            hr = HRESULT_FROM_WIN32(GetLastError());
                        }
