[Wxlua-users] Started to break apart internal.cpp

[John L. <jla...@gm...>]

I've made some pretty big changes, mainly just moving stuff around.

I've added wxlstate.h/cpp, wxLuaState, which will be replacement for
wxLuaStateVariables, It'll be a ref counted class so that it can be
passed around and if anybody holds a reference to it, they'll be able
to check if the lua_State has been closed. The current (old) way just
passes around the lua_State pointer so it's easy to write to an
invalid pointer if you're not careful.

The wxLuaState class will cleanup the GET_LUASTATEVARS_RET defines by
having a static function to get the wxLuaState from the lua_State. I
can make a constructor that takes a lua_State and attaches to it if it
already exists.

Moved wxLuaBindings into their own file, wxlbind.h/cpp.

Moved the code for wxLuaCallback into it's own wxlcallb.h/cpp file.

Renamed library.h/cpp to wxlhandl.h/cpp since it only contains wxLuaHandler=
.

Added an alternative editor to run wxLua in, app/wxluaedit using my
wxstedit component on wxCode. It's not compiled by default and I hope
I got it right. in the bakefiles. To compile it, set the environment
variable WXSTEDIT=3D/path/to/wxCode/components/wxstedit and run
in wxLua/apps/build/msw; nmake USE_WXLUAEDITAPP=3D1 -f makefile.vc
or in linux just run make in wxLua/apps/wxluaedit/src.

---------------
It's tested and works in linux using wxWidgets 2.6

In case you need a smart pointer class, wxArt2D has one and  is using it 
all over.

great! I already had used your  editing/console in my wxlua version, now 
it will be a full replacement for the old one.

We use a very simple smart pointer class for wxStrings and ints. see
wxLuaSmartStringArray
http://cvs.sourceforge.net/viewcvs.py/wxlua/wxLua/modules/wxlua/include/int=
ernal.h?rev=3D1.6&view=3Dmarkup

I don't think we need more, can you give me a link to yours?

I'm glad you like it, it's not perfect, but it's a good test for
running lua w/ c++ wxWidgets in the same thread.

Yeah, my windows machine is sloooooow so it doesn't get used too much.

It is all in the next two files, a2dSmrtPtr

http://cvs.sourceforge.net/viewcvs.py/wxart2d/wxArt2D/modules/general/include/smrtptr.h?rev=1.15&view=markup

http://cvs.sourceforge.net/viewcvs.py/wxart2d/wxArt2D/modules/general/include/smrtptr.inl?rev=1.9&view=markup

For lists we use STL -> a2dList -> a2dSmrtPtrList  derived list.
So a list of smart pointers. Easier in use then wxList when it comes to smart pointers.
Our a2dObject is derived from wxObject and has the counter for the smart pointers.

I love smart pointers. Especially in window close situations, and events, it easy to 
control when deletion will be done. And also easier during debugging. 
And with STL one almost has to use smart pointers else it will be impossible
 to store pointers, which will be deleted properly.
That is why i choose to make wxArt2D, wxList free, so later it will be easy.
The longer one waites, the worse it gets.

How does wxLua deal with wxList?

Ok, good to know.

This may come in handy for the pushed event handlers.

We don't very much if at all.
