PySide

PySide2 [5] is a Python binding of the cross-platform GUI toolkit Qt, currently developed by The Qt Company under the Qt for Python project on porting PySide[6] to work with Qt 5 instead of Qt 4. It is one of the alternatives to the standard library package Tkinter. Like Qt, PySide2 is free software. The project started out using Boost.Python from the Boost C++ Libraries for the bindings and later switched to the binding generator Shiboken[7] to reduce the size of the binaries and the memory footprint.

PySide was released under the LGPL in August 2009 by Nokia,[1] the former owners of the Qt toolkit, after Nokia failed to reach an agreement with PyQt developers Riverbank Computing[8] to change its licensing terms to include LGPL as an alternative license.

Work is currently underway to officially launch PySide2 as a Qt product. PySide2 supports Linux/X11, Mac OS X, Windows and Maemo. Support for Android is currently being added by the PySide community.[9]

Hello World example

 
# Import PySide2 classes
import sys
from PySide2 import QtCore, QtWidgets

# Create a Qt application
app = QtWidgets.QApplication(sys.argv)

# Create a Window
mywindow = QtWidgets.QWidget()
mywindow.resize(320, 240)
mywindow.setWindowTitle('Hello World!')

# Create a label and display it all together
mylabel = QtWidgets.QLabel(mywindow)
mylabel.setText('Hello World!')
mylabel.setGeometry(QtCore.QRect(200, 200, 200, 200))

mywindow.show()

# Enter Qt application main loop
sys.exit(app.exec_())
gollark: Yes. We have a Λ-4 class scenario.
gollark: Yes, I've heard about this, some kind of cascading grid issues in Texas.
gollark: The grid is very reliable here, I have power.
gollark: I would join, but I do not strictly exist.
gollark: Oh, there's no #hchat now.
