complete Qt Project creation and introduction python

One 、 establish QT project

Create a project PyPlayer:

choice QWidget:

For the convenience of later debugging , take Subsystem Set to Console ：

Two 、 Introduced in the project python, And finish python initialization

From the previous cpp_call_py project , take python Copy your environment to Pyplayer in ：

add to ./include, introduce python The header directory of :

initialization python Environment

#include <Python.h>
#include "PyPlayer.h"
PyPlayer::PyPlayer(QWidget *parent)
: QWidget(parent)
{

ui.setupUi(this);
Py_SetPythonHome(L"./");
Py_Initialize();
}

3、 ... and 、 load pyqt modular

add to python file pyqt.py

pyqt.py Is as follows ：

print("Python PyPlayer")
# The main function Called in subthread , Thread is c++ establish 
def main():
print("Python main")

stay c++ End loading module ：

#include <Python.h>
#include "PyPlayer.h"
static PyObject *pModule = 0;
PyPlayer::PyPlayer(QWidget *parent)
: QWidget(parent)
{

ui.setupUi(this);
Py_SetPythonHome(L"./");
Py_Initialize();
// Loading module 
pModule = PyImport_ImportModule("pyqt");
if (!pModule)
{

printf("PyImport import error");
PyErr_Print();
return;
}
// Open thread call python Of main function 
}

You can see that the module was loaded successfully ：
