PyMyLabel

A minimal example of using SIP to create a Python wrapper for a C++ Qt5 library.

Prerequisites

This example was written and tested with the following configurations:

Mac OSX 10.10.4 Yosemite

• Python 3.4.3
• Qt 5.4
• SIP 4.16.8
• PyQt 5.4.2
• clang-602.0.53

Windows 7 Pro SP1

• Python 3.4.2 (32bit)
• Qt 5.4
• PyQt 5.4.2 (installed from binary)
• SIP 4.16.8
• MSVC 2010

Ubuntu 16.04

• Python 3.5.2
• Qt 5.7
• PyQt 5.8.2
• SIP 4.19.2
• gcc 5.4.0

Fedora 25 Workstation

• Python 3.5.3
• Qt 5.8
• SIP 4.19.2
• PyQt5.8.2

Configuring and Compiling

The first step is run the following command:

$ python configure.py

This will use SIP to generate the necessary C/C++ wrapper code and will create Makefile's for the library itself and the wrapper.

Now you can build and install the library:

$ make
$ make install

Usage Example

from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyMyLabel import MyLabel

class Widget(QWidget):
    def __init__(self, parent=None, **kwargs):
        super().__init__(parent, **kwargs)
        
        l=QVBoxLayout(self)
        self._myLabel=MyLabel(self)
        l.addWidget(self._myLabel)
        
if __name__=="__main__":
    from sys import argv, exit
    
    a=QApplication(argv)
    w=Widget()
    w.show()
    w.raise_()
    exit(a.exec_())
