PyQt custom widget in c++

Can I write custom Qt widget in pure C++, compile it and use in PyQt?

I'm trying to use the ctypes-opencv with qt and I have performance problems with python's code for displaying opencv's image in Qt form.

Solution

  • You will have to write a Python wrapper for the widget, using the sip library (which is used by PyQt). There is a simple example for a Qt/C++ widget in the documentation.
