使用Erlang 24.3.3。

从24.3.3文档中，wx版本为2.1.3。我找到了2.1.3的wx.hrl，它不包含wxevt_webview_loaded和wxevt_webview_error。但是在文档中，它说

wxwebview中的许多方法都是异步的，即它们返回立即在后台执行工作。这包括诸如LoadUrl/2和Reload/2之类的功能。收到通知您需要处理这些功能的进度和完成提供的活动。特别是wxevt_webview_loaded通知页面或子框架完成加载时 wxevt_webview_error通知发生了错误。

我的代码如下：

Ad = wxWebView:new(Frame,?wxID_ANY,[{size,{1000,1000}}]),
lager:debug("_ad_1082:\t~p",[Ad]),
ok = wxWebView:loadURL(Ad,"http://www.baidu.com"),
wxFrame:connect(Ad, ?wxEVT_WEBVIEW_LOADED,[{callback,fun chair_launch_frame:update_webview/2},
                               {userData,{?CONST_FRAME_MAIN_AD_PRODUCER,Frame}}]),
wxFrame:connect(Ad, ?wxEVT_WEBVIEW_ERROR,[{callback,fun chair_launch_frame:update_webview/2},
                                {userData,{?CONST_FRAME_MAIN_AD_PRODUCER,Frame}}]),

编译器给出错误MESSAGE 未定义的宏'wxevt_webview_loaded'

原文

erlang 24.3.3 is used.

From the 24.3.3 document, the wx version is 2.1.3.
I have find 2.1.3's wx.hrl and it doesn't contain the wxEVT_WEBVIEW_LOADED and wxEVT_WEBVIEW_ERROR.
But in the doc, it says

Many of the methods in wxWebView are asynchronous, i.e. they return
immediately and perform their work in the background. This includes
functions such as loadURL/2 and reload/2. To receive notification of
the progress and completion of these functions you need to handle the
events that are provided. Specifically wxEVT_WEBVIEW_LOADED notifies
when the page or a sub-frame has finished loading and
wxEVT_WEBVIEW_ERROR notifies that an error has occurred.

My code is as follows:

Ad = wxWebView:new(Frame,?wxID_ANY,[{size,{1000,1000}}]),
lager:debug("_ad_1082:\t~p",[Ad]),
ok = wxWebView:loadURL(Ad,"http://www.baidu.com"),
wxFrame:connect(Ad, ?wxEVT_WEBVIEW_LOADED,[{callback,fun chair_launch_frame:update_webview/2},
                               {userData,{?CONST_FRAME_MAIN_AD_PRODUCER,Frame}}]),
wxFrame:connect(Ad, ?wxEVT_WEBVIEW_ERROR,[{callback,fun chair_launch_frame:update_webview/2},
                                {userData,{?CONST_FRAME_MAIN_AD_PRODUCER,Frame}}]),

The compiler give error messsage undefined macro 'wxEVT_WEBVIEW_LOADED'
