Sounds great. I've yet to play with Lua scripting in SciTE, but it
sounds interesting. Thanks for posting the HOWTO as well.

controls.wx.lua is a little nuts in that we bind to every control and
every event for each control. If you do find which control is or event
is causing the problem we can work on it.

Have you looked into how much code is involved in the SciTE Lua
module? Could a thin wrapper be written around it so that it would
call wxLua's wxSTC functions instead of the original SciTE functions?
In that case you could use all the SciTE Lua functions, but with a
wxLua wxSTC editor. Just a thought.
Regards,
 John

I think the problem is with
treeCtrl:SetImageList(wx.wxImageList(16, 16))
you need to have something like this
-- DO NOT DELETE this until the treeCtrl is deleted
-- i.e. make it a global var and let wxLua delete it when the program ends
imgList = wx.wxImageList(16, 16)
treeCtrl:SetImageList(imgList)
The issue is that the wxTreeCtrl does not take ownership or copy the
pointer to the wxImageList
so all wxLua can do is pass in it's copy and so you must keep it
around at least as long
as the wxTreeCtrl exists or you call wxTreeCtrl::SetImageList(wx.NULL).

Hope this works,
 John

Hello, I'm new to wxLua and have spent last days compiling it "just
right". So, I'm posting this report in hope it will help anyone who
has problems similar to mine.
Intro.
SciTE editor (http://www.scintilla.org/SciTE.html) is a Scintilla based
source code editor, it supports all Scintilla features and is highly
configurable. It has built-in Lua interpreter (merged into SciTE.exe)
and provides Lua scripts control over Scintilla component, though not
in the way wxSTC does, its not wxWidgets-compatible.
So, the idea was to provide SciTE with wxLua capabilities using as
few DLL's as possible and utilizing its internal Lua capabilities.
And here goes "how-to" manual, detailed to the limit of being
offensive.
---------------------------------------------------------------------
0. Prerequisites:
Free downloadables (all native default packages):
MS Visual C++ 2008 Express
wxWidgets 2.8.11 source
wxLua 2.8.10.0 source
SciTE editor
unpack wxWidgets to C:\wxWidgets
unpack wxLua to C:\wxLua
create WXWIN environment variable and set it to 'C:\wxWidgets' (no quotes in value)
1. Make BUILD.BAT to compile makefile.vc 
 call "C:\Program Files\Microsoft Visual Studio 9.0\VC\vcvarsall.bat"
 nmake /s /f makefile.vc 
2. Go to C:\wxWidgets\build\msw\
config.vc: 
 SHARED = 1
 WXUNIV = 0
 UNICODE = 0
 MSLU = 0
 BUILD = release
 TARGET_CPU = $(CPU)
 DEBUG_INFO = default
 DEBUG_FLAG = default
 DEBUG_RUNTIME_LIBS = default
 MONOLITHIC = 1
 USE_GUI = 1
 USE_HTML = 1
 USE_MEDIA = 1
 USE_XRC = 1
 USE_AUI = 1
 USE_RICHTEXT = 1
 USE_OPENGL = 1
 USE_ODBC = 1
 USE_QA = 1
 USE_EXCEPTIONS = 1
 USE_RTTI = 0
 USE_THREADS = 1
 USE_CAIRO = 0
 USE_GDIPLUS = 0
 OFFICIAL_BUILD = 0
 VENDOR = custom
 WX_FLAVOUR =
 WX_LIB_FLAVOUR =
 CFG = 
 CPPUNIT_CFLAGS = 
 CPPUNIT_LIBS = 
 RUNTIME_LIBS = dynamic
3. Run BUILD.BAT and build it (when I say 'run BUILD.BAT' I mean copy it in this folder and start it from here)
4. Go C:\wxWidgets\contrib\build\ogl and run BUILD.BAT
5. Go C:\wxWidgets\contrib\build\stc and run BUILD.BAT (some warnings may happen - its ok)
6. Go C:\wxWidgets\lib\vc_dll
Rename wxmsw28_ogl.lib to wxmsw28_gl.lib
7. Go C:\wxLua\modules\build\msw
makefile.vc: set config at file beginning as following
 CC = cl
 CXX = cl
 CFLAGS = 
 CXXFLAGS = 
 CPPFLAGS = 
 LDFLAGS = 
 BUILD = release
 UNICODE = 0
 SHARED = 1
 WX_SHARED = 1
 WX_VERSION = 28
 WX_MONOLITHIC = 1
 WX_DIR = $(WXWIN)
 USE_APPS = 0
 USE_SYSTEM_LUA = 0
 LUA_INCLUDE_DIR = ..\..\..\modules\lua\include
 LUA_LIB_DIR = ..\..\..\modules\lua\lib
 RUNTIME_LIBS = dynamic
 THREADING = multi
 USE_WXBINDADV = 1
 USE_WXBINDAUI = 1
 USE_WXBINDBASE = 1
 USE_WXBINDCORE = 1
 USE_WXBINDGL = 1
 USE_WXBINDHTML = 1
 USE_WXBINDMEDIA = 1
 USE_WXBINDNET = 1
 USE_WXBINDRICHTEXT = 1
 USE_WXBINDSTC = 1
 USE_WXBINDXML = 1
 USE_WXBINDXRC = 1
 USE_WXLUADEBUG = 1
 USE_WXLUASOCKET = 0
 USE_LUAMODULE = 1
 MONOLITHIC_LUAMODULE = 1
 USE_WXLUAAPP = 0
 USE_WXLUACANAPP = 0
 WXSTEDIT_DIR = $(WXSTEDIT)
 USE_WXLUAEDITAPP = 0
 USE_WXLUAFREEZEAPP = 0
makefile.vc: scroll to line "..\..\..\lib\vc_$(VAR_205)\lua5.1.dll: make_dir_lua_dll $(LUA_DLL_OBJECTS)" and fix "/OUT" argument on line after this one as following
 /OUT:..\..\..\lib\vc_$(VAR_205)\SciTE.exe
 
this will enable to use SciTE.exe as a host app for wxLUA (instead of lua5.1.dll)
8. (Optional) Disable wxSTC component (cause SciTE is built on Scintilla anyway and you probably wont need one more text editor inside)
Go C:\wxLua\modules\build\msw
makefile.vc: set config at file beginning as in [7], only change
 CPPFLAGS = /DwxLUA_USEBINDING_WXSTC^#0 
scroll to line " vcmsw$(WXLIBPOSTFIX)$(_BUILDDIR_SHARED_SUFFIX)\mod_luamodule_mono_wxstc_bind.obj \" and put '#' in front of it to comment this line out
9. run BAT and build wxLua
10. Now we done compiling. The result is 3 dll files (or 2 if you disabled wxSTC):
 C:\wxWidgets\lib\vc_dll\wxmsw28_vc_custom.dll (around 6Mb)
 C:\wxWidgets\lib\vc_dll\wxmsw28_stc_vc_custom.dll (optional)
 C:\wxLua\lib\vc_dll\wx.dll (2-3 Mb)
 
11. Install wxLua as a module to SciTE
Put all 3 (or 2) dll's into SciTE installation folder (where SciTE.exe is)
Open 'SciTEGlobal.properties' and make sure startup lua script is set:
 ext.lua.startup.script=$(SciteDefaultHome)\Startup.lua
Create/edit 'Startup.lua', adding following lines:
 package.cpath = package.cpath..";./?.dll;"
 require("wx")
 
Close and restart SciTE.exe - if no error message boxes pops up and no error messages in output window of SciTE, installation is successful
12. Test wxLua from SciTE.
Open 'lua.properties' config file and scroll to the bottom of it.
Make sure SciTE will use internal LUA interpreter to run *.lua files - insert following 2 lines at the end of a file
 command.go.*.lua=dofile $(FileNameExt)
 command.go.subsystem.*.lua=3
Restart SciTE and open some *.lua from 'C:\wxLua\samples'
Hit F5 to start file execution
note: editor.wx.lua wont run if you disable wxSTC. Also i had problems with 'controls.wx.lua' (some controls and events wont work)
--------------------------------------------------------
Conclusion.
To allow SciTE run several Lua scripts at once look here:
http://lua-users.org/wiki/SciteExtMan
It would be nice to also have wxSTC interface to SciTE's Scintilla
component, but it's highly unlikely for SciTE author to switch into
using wxWidgets and would require otherwise creating bindings from
Lua to Scintilla directly, while emulating wxWidgets framework,
which is way beyond my capabilities.
Also I'd like to mention I never worked outside of Windows© so i wont
be able to 'translate' this how-to into $(YOUR_OS_OF_CHOICE).

Hi, I'm just getting started using wxLua, and have hit a couple of problems.
I tried writing a small file-tree view with Icons in wxLua but had a
few issues. I've included the code at the end of this email.
If I run it as-is (with 'lua fileview.lua') I get a segmentation fault
after a few icons have loaded. If I disable garbage collection (with
collectgarbage('stop')) then the segfault goes away, but I get error
messages saying that the icons couldn't be loaded (the filenames seem
to be strings such as "gnome-compressed" and not actual filenames). If
I hardcode a path to an icon, then it loads properly, though all the
files obviously have that one icon. Either way, if I turn garbage
collection back on I get a segmentation fault.
I'm using the GTK port of wxWidgets, compiled from the 2.8.11 source
tarball with --enable-debug. My version of wxLua was also compiled
from the source tarball. I'm using a 64-bit installation of Ubuntu
10.4, and running in the Gnome desktop environment.
Also, in case it's important, the wxIcon(wxIconLocation) constructor
seems not to be bound, so I'm using wxIcon(iconLoc:GetFileName(),
wx.wxBITMAP_TYPE_ANY) instead.
Is there a bug, or am I doing something very wrong? :x
 henk
PS. This is the code I'm trying to run. I added a
collectgarbage('collect') call in a place which seems to cause it to
consistently crash every time.

Can you use wxWindow::SetDropTarget() as per this overview?
http://docs.wxwidgets.org/stable/wx_wxdndoverview.html
I'm not sure if you have to override wxDropSource::DoDragDrop(), but I
guess you do. What are your problems?

The best place to look is in the bindings. For example, the link below
shows the wrappers for the wxWindow type classes.
Search for "wxLua_wxStaticText_Wrap"
http://wxlua.cvs.sourceforge.net/viewvc/wxlua/wxLua/modules/wxbind/src/wxcore_windows.cpp?view=markup
Hope this helps,
 John

Hi,
In a C++ function called from Lua, how can I retrieve the regular
wxWidgets class wrapped by wxLua?
Let's say I have a function:
 int foo(lua_State* L);
and it is called from Lua, with a (wxLua) wxStaticText object on top
of the Lua stack. How can I access the underlying C++ wxStaticText
class and e.g. call SetLabel(...)?
I have read the "wxLua C++ Programming Guide" section of wxlua.html,
but unfortunately I had trouble understanding it. I'd be very grateful
for an answer, especially for a fragment of code that could be used as
the body of the 'foo' function above.
Greetings
Mateusz Czapliński

Hello list,
A need to transfer data between two wxListBox using dragging.
wxLua have problem with DnD suport.
How can I do this?

Lua's coroutines can not solve my problem I think.
My situation is that I have several thread(I use luatask,because 
coroutine I think it is not suitable here) to communicate with rs232 
port,and when some data was send to wxlua main thread.
At first I did not know how to receive data from other thread in main 
thread,so I thought I can new a wxthread to wait the data from other 
thread and then send event to wxlua main thread.
Now I use the way that main thread handle the "wxEVT_IDLE",in this event 
handle I try to receive data.And it works

Unfortunately the function wxNewEventType() is not currently wrapped.
However it is simple enough to simulate one by picking some generic
event, wxEVT_COMMAND_ENTER or whatever you like, and send a
wxCommandEvent with that type and a unique ID. You will use the unique
ID to differentiate your event from other events.

You can use Lua's coroutines, see the sample coroutine.wx.lua or more
generally Google for sample code using Lua coroutines. wxThread will
be added in the 2.9 release of wxLua, which may be in a few months.
You can also see some coroutine usage in the program gpeddler2, it was
written for a very old version of wxLua so it might not run out of the
box, but wxLua hasn't changed too much. It at least might give you
some ideas.

If I want to do some mutithread programming,how can I do using wxlua in 
pure lua?
Thanks!

In wxpython define a new event can use this code:
'''
# This creates a new Event class and a EVT binder function
(UpdateBarEvent, EVT_UPDATE_BARGRAPH) = wx.lib.newevent.NewEvent()
'''
How can I do same job in lua using wxlua?
I searched for the example of wxlua(I am using Lua For Windows) and 
wxlua document,and do not find out the solution.
Can somebody tell me?
Thanks!

I have some personal projects that use wxLua in a C++ app, but I'm not sure
of any common public app that uses it. However, there's no magic to it.
wxLua code can operate on the C++ app's objects using wxGetApp(),
wxFindWindowByName(), FindId(), etc. You can write a little Lua script that
is run in the wxLuaState to present these windows to the user's script or
hide them as appropriate. You can also provide a set of your own wrappers
for Kicad's libraries (see wxLuaCan sample), that allow wxLua to
access/create your classes. I'm not sure how you will be using wxLua, but
the best way to think about it is that wxLua code is run in the main thread
(GUI code has to be in main thread), just like C++ code, and is
indistinguishable from it. (Use Lua debug hooks to catch runaway scripts)
However, if this is for end users, you may want to provide a set a
simplified Lua functions that hide dangerous things and simplify tasks.
You can mess with the C++ app from Lua in the wxLuaEdit sample program using
wxGetApp etc... In fact, wxLuaEdit/wxStEdit is designed to be used as an
embedded script editor in a C++ program, but since it's a developer's tool
no effort was made to do any sandboxing. See the code below to see how the
scripts are run, search for ID_WXLUAIDE_RUN_LUA which is the "Run" button.

 Another question - how to integrate wxLua into existing C++ wxWidgets application (for ex. Kicad) ? Is there somewhere the examples of such integration ?
