Calling python script and function

[Priya]

Hi,

I have developed a application using wxWidgets. I want to call a python script and functions directly from wxWidgets. Is it possible. If so please explain me how to do.

Hi,
You probably looking at wxExecute( "python <you_script_name_goes_here" );
Just make sure you cwd is pointing to the right direction.

BTW, out of curiosity - why not use wxPython?

Thank you.

Thanks ONEEYEMAN,

I have used wxExecute in both sync and async mode as a separate process. It works fine. But the output (say some 10 printf in one process) redirection to control prints chunk by chunk. Not prints line by line (the 10 printf of one process).

But my aim is print output each line immediate redirected to the wxwidgets control.
so i tried to embed python inside wxwidgets using pthread. it works fine. For windows 32 bit but for 64 bit it was not working.
I also required to call any function of a python script from wxwidgets just like a function call and get the output.

How i can achieve this.

I started working on c++so i used wxwidgets.

can i embed wxpython in wxwidgets or how easily i can do this?

Please respond

regards,
Priya

Hi,

for 64 bit it was not working.

What does this mean?
Compilation problem? Crash? Assert? No output/result?

Thank you.

Hi,
Compilation Problem, In win 64 bit pc i was not able to use pthread, for win 32 bit pc i downloaded pthread 32 bit dll and lib and supporting include files and placed in visual studio location. For 64 bit i was not able to download pthread.

Is it right way to use pthread approch?? or any other way is there to call python script and function directly from wxWidgets.

Thanks
Priya

What do you need a pthread for? Just use standard Windows thread mechanism thru the wxThread....
Using pthread means you have extra dependency in you code.

I would fiorget about that and just use wxWidgets' wxThread.

Thank you.

You have to use Python C-API or Boost.Python.
Form your posts it seems to be simple task so Python API should suffice. In this regard,

slightly modified from py website

Code: Select all

void main(int argc, char *argv[])
{
  Py_SetProgramName("Awesome Pyprogram");  /* optional but recommended */
  Py_Initialize();
  wxString fileContents;
  // .... read python file using wxFile or similar way into fileContents
  PyRun_SimpleString(fileContents.c_str().AsChar());
  Py_Finalize();
}

if you need interactions then you need to dig deep into the Py C-Api
