Where are you getting the scroll position from? The event or the
window itself? You should compare the two.

If you want to process something after an event comes, create a new
event with whatever event type you want and a unique id you can use to
discriminate it and add it as a pending event to be sent after the
current event is handled.
local updateEvent = wx.wxCommandEvent(wx.wxEVT_COMMAND_BUTTON_CLICKED,
ID_REFRESH_GRID_SCROLL);
mywindow:GetEventHandler():AddPendingEvent(updateEvent);
then when you get this event in your handler for it, sync the scrollbars.

 John

To answer your question; I believe that previously I had not fully
made it possible to build staticly and that is why it depends on it.
The program depends22, dependency walker lets you view dll dependences
in Windows as ldd does in Linux.

To make a completely standalone app you want:
BUILD_SHARED_LIBS=FALSE
wxLua_LUA_LIBRARY_BUILD_SHARED=FALSE
and, of course, you need wxWidgets built staticly, too. That way
everything will be staticly linked into a single executable.

 John

To build a standalone app with wxLuaFreeze you'll want to build
staticly. Again, you can use "ldd appname" to see what libs it depends
on.

Hello,
 I was having this problem where the exe I created from wxluafreeze
would not run since it was not able to find the dll file that I was
requiring in the code. The dll was in the same directory as the exe.
Strangely the problem got fixed when I put lua51.dll in the same directory
as the exe as well. Is there any particular reason it behaves this way?
Thanks,
Milind

Hi,
 So I still get the problem where my wxluafreeze created exe cannot
locate the dll file in the same directory. It has to do with something how
windows launches the exe and maybe sets it to a different default run
directory. Does anybody have a idea about this?
Thanks,
Milind

Hi,
 I have 2 wxGrid windows side by side and I want to synchronize the
scroll on the 2 windows. The scroll event works fine but when I read the
scroll position of the window and set the scroll on the other window it
does not sync up. There is a lag. It seems that the actual scroll happens
after my event handler is processed so my other window always gets to the
position where the 1st one was before.
Is there a way to let the scroll happen and then read the scroll position?
The wxWidgets forum said that there is a hidden function called
HandleOnScroll, which I tried but it does not work in wxLua. Is there any
other way?
Thanks,
Milind

Open your program in wxLua by calling.
$ wxLua -o program.lua
The Debug menu has items for executing and debugging it. To set
breakpoints click on the margin and red squares appear, be sure to put
them on code lines. Then click Debug->Start Debugging and a green
arrow appears on the line where the debugger is stopped. Press F11 to
step, click "View call stack" to view the stack and browse all
variables in Lua, you can also set watches to print variable values
(when they're in scope).

 Yes I see that I need to have it in a separate file and then it works.

Hi Milind,
I quickly tried that in wxLua, but couldn't figure out how to specify
the folder to run scripts in so that loadfile and io.open would work.
I also tried to do this in ZeroBrane Studio
(https://github.com/pkulchenko/ZeroBraneStudio) and it seems like it
may work for you (the IDE is wxlua based). I'm not sure what your code
looks like, but let's say you have loadedfile.lua script that you are
trying to load and it has the following lines:
-- loadedfile.lua
print "123"
print "456"
function foo()
 print "foo"
end
You also have loadfile.lua script which has something like this:
-- loadfile.lua
--local func = loadfile('loadedfile.lua')
local f = assert(io.open('loadedfile.lua'))
local str = f:read('*all')
f:close()
local func = loadstring(str, 'loadedfile.lua')
func()
foo()
print 'Done'
If you open both of these files in ZeroBrane Studio and start
debugging with loadfile.lua being in the active editor window, you
should be able to step through both of them. You can also set a
breakpoint on either of the files and it should work.
Note that I added "loadedfile.lua" as a parameter for loadstring(),
which informs the debug interface as to where to search for the source
code.
Paul.

Hi,
 I have a lua program in which I load a lua script as a string
(loadstring) and then execute it. Is it possible to debug this script in
wxLua.exe? How would I add a breakpoint in there?

Hummm, I can't get to Windows machine right now, but I wonder if it's
something to do with the conversion to a Lua ansi string rather than
wxGetCwd() not returning the right value.
Try this:
s = wx.wxString([[D:\Lua\下载\下载\]])
print(s:GetData())
s2 = s:GetData()
print(s2)

Yes. Everything else Unicode-related is working as far as I can tell.

yes, it does seem like the problem is with GetCwd, and it should be
easy to reproduce:
> wx.wxFileName.SetCwd([[D:\Lua\下载\下载\]]); print(wx.wxFileName.FileExists("foo.lua")); print(wx.wxGetCwd()); print(wx.wxFileName.SetCwd(wx.wxGetCwd()))
true
D:\Lua\??\??
false
As you can see, the file is there, but using the result of GetCwd to
set it as the current folder fails (returns "false" the second time).

Does wx.wxFileName.FileExists("SomethingInThatDir.txt") work, showing
that SetCwd() worked?
If so then, it'd be a problem with GetCwd(), but I cannot think of any
reason why it wouldn't work off the top of my head...

You're probably building all shared libraries? This means that wx.so
links to the other wxLua libraries and wxWidgets libraries which
contain all the code. This is the typical Linux model where these
shared libs can be linked to by many apps or other libs reducing the
overall size of all the apps/libs on disk.
Run "ldd wx.so" to see what libs it depends on.
I decided to try to put everything into the wx.dll for Windows since
having a whole bunch of shared libs is more trouble since the DLLs
have to be in the path or same dir and "Windows people" are not as
used to seeing a whole bunch of shared libs along with the app.

 John

Hi,
 I used wxluafreeze to convert my application to an executable file
in linux. But I see that the wx.so file that I have in linux is 446KB while
in windows wx.dll was 5.7MB and there is a similar difference between my
application size. Is this right? Do the wx libraries have such a big size
difference or is there something missing in my linux library.
Thanks.

Thanks I will re check that if I get access to that computer again.

Hi John,
> This does not show the error dialog for me in Linux.
it seems like you need to have a frame open to see the effect (your
code works regardless of whether LogNull is there). Try the code
below.
The solution is indeed to use "local log = wx.wxLogNull()", but it
needs to be used *before* wxFile constructor, because this is where it
is failing (not in the Write method as I thought initially). Thanks
for getting me on the right track.
require "wx"
function FileWrite(file,content)
 -- local log = wx.wxLogNull() --<-- LogNull code should be here
 local file = wx.wxFile(file, wx.wxFile.write)

This does not show the error dialog for me in Linux.
local log = wx.wxLogNull()
local file = wx.wxFile("/aaa", wx.wxFile.write)
print(file:IsOpened())
if (file:IsOpened())
 -- This asserts as it should if the file is not opened
 file:Write("something", #"something")
end()
log:delete()

To be sure, the problem is on windows? And the two machines both have
the same version, XP or 7?
If everything is the same I cannot think of any reason why it would
find it on one and not the other. I would double/triple check that the
files really are the same or that there isn't some difference in the
permissions, though MSWindows seems to ignore them for the most part.

Hi all,
I'm working with an application that saves data in files and some of
the operations may trigger file errors. I'm handling those errors
myself and don't want to see the standard error message shown by
wxwidgets. How do I disable it? Here is the code that I have:
 local file = wx.wxFile(filename, wx.wxFile.write)
 file:Write("something", #"something")
If the file is write protected, I get "can't open file '...' (error 5:
access is denied)". I know, I can check for that condition, but this
is not what the question is about. I'd like to disable that message.
Here is what I tried so far:
1. use wxLogNull. I read C++ examples, but not sure how this should be
used in wxlua (according to examples, you just need to "instantiate"
this logNull object):
local log = wx.wxLogNull()
file:Write(....)
log:delete()
This has no effect.
2. use SetActiveTarget()
local log = wx.wxLog.SetActiveTarget(wx.wxLogNull())
file:Write(....)
wx.wxLog.SetActiveTarget(log)
This doesn't work as SetActiveTarget expects wxLog object, but
wxLogNull doesn't seem to be inherited from wxLog (according to wxlua
docs).
3. use EnableLogging on either wx.wxLogGui() or wx.wxLog()
local curr = wx.wxLogGui().EnableLogging(false)
file:Write(....)
wx.wxLogGui().EnableLogging(curr)
This has no effect.
What is the right way to (temporarily) disable logging such that I
don't get the log window? Thanks.
Paul.
