add_StatusBarTextChanged

Add an event handler for the StatusBarTextChanged event.

public HRESULT add_StatusBarTextChanged(ICoreWebView2StatusBarTextChangedEventHandler * eventHandler, EventRegistrationToken * token)

StatusBarTextChanged fires when the WebView is showing a status message, a URL, or an empty string (an indication to hide the status bar).

        m_statusBar.Initialize(appWindow);
        // Registering a listener for status bar message changes
    CHECK_FAILURE(m_webView2_12->add_StatusBarTextChanged(
        Microsoft::WRL::Callback<ICoreWebView2StatusBarTextChangedEventHandler>(
                [this](ICoreWebView2* sender, IUnknown* args) -> HRESULT {
                    if (m_customStatusBar)
                    {
                        wil::unique_cotaskmem_string value;
                    Microsoft::WRL::ComPtr<ICoreWebView2_12> wv;
                        CHECK_FAILURE(sender->QueryInterface(IID_PPV_ARGS(&wv)));

                        CHECK_FAILURE(wv->get_StatusBarText(&value));
                        std::wstring valueString = value.get();
                        if (valueString.length() != 0)
                        {
                            m_statusBar.Show(valueString);
                        }
                        else
                        {
                            m_statusBar.Hide();
                        }
                    }

                    return S_OK;
                })
                .Get(),
