Oops, I meant if ev.GetSocketEvent() == wxSOCKET_INPUT, of course

Aha - I think the docs were throwing me off the trail on that point, as
wxSOCKET_INPUT is listed in a table under "wxSocket Events". I thought they
would be on par with other event types.

In the wxLua reference I had found the line

 *%define_event* wxEVT_SOCKET // EVT_SOCKET(id, func)

...but didn't know what it meant. So the approach, then, is to do something
like this?

sock:SetEventHandler(someHandler, wxEVT_SOCKET)
someHandler:Connect(wxEVT_SOCKET, function (ev) if ev == wxSOCKET_INPUT then
... end)

Hope this helps,

Thank you, it definitely does - I'll try it out tonight and post back if I
run into any roadblocks.

wxSOCKET_INPUT is an enum wxSocketNotify, an integer with a value of
0, not an event type.

The EVT_XXX() are C_++ macros that statically connect events at
compile time, so wxLua cannot use them, instead we use the dynamic
events and the wxEvtHandler::Connect() function.

The mapping between the EVT_XXX() macros and the dynamic event types
are described in the doc below. Search for EVT_SOCKET and you'll see
that you want to use wxEVT_SOCKET and that you will get a
wxSocketEvent object in your callback function. Note that the names
aren't always so easy to guess.

http://wxlua.sourceforge.net/docs/wxluaref.html

You can use any wxEvtHandler derived class you want, typically people
will use their wxFrame or a wxWindow that they already have.

Hope this helps,

Hi all,

I'm writing a wxLua app which needs socket functionality, and I'm having
trouble figuring out how to handle events from wxSocketClient. wxSocketBase
doesn't inherit from wxEvtHandler, meaning Connect() isn't an option. I went
looking and found this:

http://docs.wxwidgets.org/stable/wx_wxsocketbase.html#socketevents
http://docs.wxwidgets.org/stable/wx_wxsocketbase.html#wxsocketbaseseteventhandler

So I tried to set up a plain wxEvtHandler object, hooking it up to the
wxSocketClient with SetEventHandler(), and trying to Connect() the
wxEvtHandler to wxSOCKET_INPUT - but that apparently fails?

"Lua: Error while running chunk
...
wxLua: Invalid or unknown wxEventType for wxEvtHandler::Connect() : 0,
winIds -1, -1."

I can't seem to find any example code using wxSocketClient in Lua anywhere.
All the C++ code I've seen uses the EVT_SOCKET macro, but that's not
available in pure Lua.

I'm stumped. How does one receive wxSocketClient events in a wxLua program?

Thanks,

Evan
