Is it possible to embed C++ widget to PyQt application?
I have a PyQt5 application and most widgets written in Python. I want to write some widget in C++ Qt to make it faster and then embed it into my PyQt QMainWindow.
Is it possible?

You can use SIP to be able to execute a widget created in C ++ from python, in the following link I show an example of how to do it.
The structure of the example is as follows:
├── configure.py
├── sip
│ ├── AnalogClock.sip
│ └── PyAnalogClock.sip
└── src
├── analogclock.cpp
├── analogclock.h
├── analogclockl_global.h
└── AnalogClock.pro
In the src folder you must create the widget library
In the sip folder you must place the structure of the class that you will expose:
AnalogClock.sip
%Import QtGui/QtGuimod.sip
%Import QtWidgets/QtWidgetsmod.sip
%If (Qt_5_0_0 -)
class AnalogClock : public QWidget{
%TypeHeaderCode
#include "analogclock.h"
%End
public:
AnalogClock(QWidget *parent /TransferThis/ = 0);
protected:
virtual void resizeEvent(QResizeEvent *);
virtual void paintEvent(QPaintEvent *e);
};
%End
PyAnalogClock.sip
%Module(name=PyAnalogClock, call_super_init=True, keyword_arguments="Optional")
%DefaultMetatype PyQt5.QtCore.pyqtWrapperType
%DefaultSupertype sip.simplewrapper
%Include AnalogClock.sip
configure.py is the script that configures the compilation of the project, if you have any problems you must modify some path (it has been tested in Linux)
It is then compiled by executing the following:
python configure.py
make
sudo make install
When executing the previous one it generates a folder called modules, inside of it is the dynamic library, in the case of the example PyAnalogClock.so, this file we place it in the folder of the source code:
.
├── main.py
└── PyAnalogClock.so
main.py
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyAnalogClock import AnalogClock
if __name__=="__main__":
import sys
a=QApplication(sys.argv)
w=AnalogClock()
w.show()
sys.exit(a.exec_())
output:

You can use SIP to create bindings for your C++ code the same way that the PyQt bindings are made.
However, the bindings generated by SIP are themselves C++ code, and in the case of PyQt link directly into the Qt binaries. If you just intend to rewrite PyQt code as C++ then any speedup realised will be negligible, as very little native python is executed in the first place.
