Hi,
I'm trying to understand how wxLua handles its event mechanism. I can see that
for every call to Connect(), wxLua will create a new object of
wxLuaEventCallback.
But I don't see where these get deleted.
My assumption is that whenever a window is closed, wxLuaWinDestroyCallback will
do the cleaning up and AFAICS it iterates over all event callbacks and calls
wxlCallback->ClearwxLuaState();
on every callback it finds. But it also does the following:
wxluaR_unref(L, wxlCallback->GetLuaFuncRef(), &wxlua_lreg_refs_key);
This is confusing me because this is also done in the wxLuaEventCallback dtor:
m_wxlState.wxluaR_Unref(m_luafunc_ref, &wxlua_lreg_refs_key);
So are function references possibly removed twice here?
But back to my original question: I'd like to know which code causes the
wxLuaEventCallback dtor to be called. My assumption is that it is
ClearWxLuaState()
because that decrements the reference count and then the object might be marked
for garbage collection by the wxWidgets main loop.
But I don't know enough about C++ and wxWidgets so I'd really be glad if
somebody could tell me if my assumption is right. I just need to know what
code in wxLua triggers the wxLuaEventCallback dtor.
Thanks!
