wxlua-users Mailing List for wxLua

I am using a fairly recent trunk of wxLua with wxWidgets 2.9.4 and have 
found a problem with lua_PushString and GetStringType. lua_PushString 
relies on wxString to convert the wxString to char *. The default 
conversion uses c_str which causes a problem when converting non-ASCII 
characters. GetStringType uses lua2wx which by default converts from 
UTF8 to wxString.

For versions of wxWidgets before 2.9.0 lua_PushString uses wx2lua to 
convert the wxString to UTF8. Why is this disabled for 2.9.x?

Hi Paul,
          Thanks for looking at this. Actually it is not just Lua 4
windows. If you just download the wxlua binary for windows and copy
editor.wx.lua to the bin directory which has all the executables and run it
with lua and also run it with wxluafreeze.exe you will see the same
differences. So either the wx.dll in the wxlua distribution is different
somehow than wxluafreeze's statically linked library or wxluafreeze does
something extra than just having the wx library.
          I am really curious to find out about this since it raises a
question in my mind is whether wxlua is truly a lua module or it is a
separate lua distribution.

Thanks,
Milind

Hi Milind,

> So any ideas why are these subtle differences?

No; I'd not expect to see any differences. I just checked and I do see
them between using lua.exe and wlua.exe. For example, when running
from wlua.exe, the toolbar has a gradient that I don't see when
running lua.exe.

We may need to find L4W sources to see what really happens in
wlua.exe. As far as I can tell, lua.exe is just a normal lua
interpreter that loads wx.dll.

Paul.

Hi Milind,

The only difference should be is that wxluafreeze includes wx library
statically compiled (so you don't need anything else) and in other
cases your executables expect wx.dll.

I'm not sure what graphics are different. Can you do two screenshots
and mark the differences on them? I don't use wxluafreeze, but I
wouldn't expect to see any differences.

Paul.

As a simple test that can be done to see the difference is, just copy the
editor.wx.lua file into the bin directory of the wxlua package and run it
with lua.exe and wxluafreeze.exe. The graphics are slightly different. What
is missing in the Lua.exe execution to cause it to show different graphics?

Thanks,
Milind

Hi,
       I have installed Lua for windows and when I run my program with
Lua.exe (my program has require("wx")) the graphics are a little different
compared to if I run it with an executable wlua also in the package. I see
the same graphics as wlua if I run my program using wxluafreeze from the
downloaded wxlua binary package.
       Is there a difference of launching the program through Lua or
through wLua? I am not sure what is different in wLua because it is just a
35KB executable and if I remove all wx.dll from the system then it is not
able to execute the program while wxluafreeze still can execute the program
without the wx.dll file.

So what is the difference?

Thanks,
Milind

Hi Milind,

> I just started using the studio and it is very good. Only thing is when I go into debug it executes my program using lua. I like to execute it using wxlua. How can I configure that?

You can change the executable that is used to run/debug the scripts.
The example is here
(https://github.com/pkulchenko/ZeroBraneStudio/blob/master/cfg/user-sample.lua#L44)
and instruction are here
(http://studio.zerobrane.com/doc-configuration.html)

> Also is the UI done in wxlua? If yes how do you implement the main text with down with different colors, breakpoint mark and line numbers?

Yes, everything is done in wxlua. The editing component is Scintilla,
so all I need to do is to configure it to display proper margins,
markers, and set colors I want. This is mostly done in
src/editor/editor.lua (CreateEditor) and src/editor/style.lua (where
all the style information is processed).

Paul.

Hi Paul,
      I just started using the studio and it is very good. Only thing is
when I go into debug it executes my program using lua. I like to execute it
using wxlua. How can I configure that?
      Also is the UI done in wxlua? If yes how do you implement the main
text with down with different colors, breakpoint mark and line numbers?

Thanks,
Milind

Hi John,

Thank you for adding wxEVT_LUA_ERROR and wxTreeCtrl::SetItemState.

There are couple of other (relatively easy) methods that are missing
from the binding: wxMenu SetParent and GetParent methods
(http://docs.wxwidgets.org/trunk/classwx_menu.html#abfba34a537e6a69ee6531e333dfbeacb);
these are 2.9 methods. Would it be possible to add these as well?
Thank you.

Paul.

Hi All,

Does anyone have a simple drag and drop example that works with wxlua?
I've seen an example in this ticket
(http://sourceforge.net/tracker/index.php?func=detail&aid=3060958&group_id=140042&atid=745327),
but can't get it to work. It seems like I'm missing SetDropTarget
call, but I can't figure out what to pass it as a parameter. According
to the docs (http://docs.wxwidgets.org/2.8/wx_wxwindow.html#wxwindowsetdroptarget)
it expects wxDropTarget, but wx.wxDropTarget is an empty table for me,
so I'm not sure how to instantiate it.

I need to implement it for wxTreeCtrl and wxStyledTextCtrl, but any
working example will help. Thank you.

Paul.
