Summary: using python extension(wxPython) in c
Initial Comment:
hello,all.
i am confronting with a weird problem, almost forcing to die,the feeling
is miserable, so pls help me.
here is a python application named "helloWorld",a simple gui application,
assisted with wxPython.
from wxPython.wx import *
class myApp(wxApp):
def OnInit(self):
frame = wxFrame(NULL,-1,"hello,world!");
frame.Show(true)
self.SetTopWindow(frame)
return true
app = myApp()
app.MainLoop()
also sorry for my unsmart code, which i should import wx not wxPython.wx.
and i want to use the simplest way to combine with c.so i use:
#include "python.h"
#include "wx/wxPython/wxPython.h"
#include <iostream>
using namespace std;
int main()
{
Py_Initialize();
if(!Py_IsInitialized())
{
cerr << "hello,world!"<< endl;
return -1;
}
PyRun_SimpleString("from wxPython.wx import *");
PyRun_SimpleString("class myApp(wxApp):");
PyRun_SimpleString(" def OnInit(self):");
PyRun_SimpleString(" frame = wxFrame(NULL,-1,"hello,world!")");
PyRun_SimpleString(" frame.Show(true)");
PyRun_SimpleString(" self.SetTopWindow(frame)");
PyRun_SimpleString(" return true");
PyRun_SimpleString("app = myApp()");
PyRun_SimpleString("app.MainLoop()");
Py_Finalize();
return 0;
}
in addition, to make this work, i have configure something like this:
add the wxpython include/library files in vc.
includes:
c:\wxPython-src-2.6.3.3\wxPython\include.
c:\python24\include\wx(it is the product of building wxPython)
also the python include here.
c:\python24\include
libraries:
c:\wxPython-src-2.6.3.3\lib\vc_dll(the build product of wxWidgets)
c:\wxPython-src-2.6.3.3\wxPython\wxPython
c:\python24\libs
to supplement the problem, i install wxPython from source code,and i have
gotten three files,all of which will be uploaded here.
and both them can pass the build process,but get "detected memory leaks and
dump objects"in the run process.
i figure that it has great memory leaks when loading certain symbols,like
wxmsw26ud.lib or such,while other lib are not loaded "no symbol loaded!"
but i donot know why, and donot know how to build a wxPython script within c.
here is the error message:
Detected memory leaks!

thanks one billion times if someone can tell me,coz the progress should be
advanced further.and all my other people awaits it.
