"""Minimal Python 2 & 3 shim around all Qt bindings DOCUMENTATION Qt.py was born in the film and visual effects industry to address the growing need for the development of software capable of running with more than one flavour of the Qt bindings for Python - PySide, PySide2, PyQt4 and PyQt5.

Whenever we create a PyQt application we need to define a QApplication. This will be where we can place our window and widgets. Next we can decide on what we want to go in our application. In my case I've started by creating a QMainWindow. You can think of this like a container that will hold all of our widgets (buttons, labels, etc.).

Sep 26, 2018 · PySide is a binding to Qt4, whereas PySide2 is a binding to Qt5. For your original example, all you have to do is change the import to this from PySide2.QtWidgets import * or if you want to be prepared for all cases…
Sep 26, 2018 · PySide2 / Qt5 has migrated many of their classes away from the QtGui module to QtWidgets. QWidget is one of them.

QtWidgets import *

It is written using PyQt5, but you can easily convert it to PySide2 - just replace PyQt5 with PySide2 in the imports at the top of the file, and replace pyqtSignal with Signal on line 4. The example also requires an image file named "image.jpg" in the current directory (or you can just edit the default path in the loadImage method).
Tutorial: Creating GUI Applications in Python with QT by Alex Fedosov. Python is a great language with many awesome features, but its default GUI package (TkInter) is rather ugly.
For example, in a word processor, if the user presses a Bold toolbar button, the Bold menu item will automatically be checked. Actions can be created as independent objects, but they may also be created during the construction of menus; the PySide.QtGui.QMenu class contains convenience functions for creating actions suitable for use as menu items.
You can't mix the python cmds api with PySide2 like that. cmds.window() is a different api operating on the ELF UI widget string paths. If you want to delete a window you can call window.deleteLater().
The PySide.QtGui.QApplication class manages the GUI application’s control flow and main settings. PySide.QtGui.QApplication contains the main event loop, where all events from the window system and other sources are processed and dispatched. It also handles the application’s initialization, finalization, and provides session management.
We'll let the examples speak for themselves. Below are both the methods listed, first PyQt5 then PySide2. import sys from PyQt5.QtWidgets import QApplication from PyQt5 import uic app = QApplication(sys.argv) window = uic.loadUi("testfile.ui") window.show() sys.exit(app.exec_()) Now PySide2:

Nov 04, 2009 · This approach is mostly useful for debugging. It can also be used to handle mouse events sent to disabled widgets, which QApplication normally discards. We can subclass QApplication and reimplement notify(). Qt calls QApplication::notify() to send out an event. Reimplementing this function is the only way to get all the events, before any event ...

It is shown, and then the QApplication object's exec_ method is called, which starts the application's main event loop. Some specifics about this example: Note that QApplication's constructor receives sys.argv as an argument; that allows the user to use command-line arguments to control the look, feel, and behavior of a Python/Qt application.
In our last instalment, we discussed Qt's QListWidget class, which allows the user to make simple single-column list boxes. For more advanced list controls, however, a more flexible widget is required; for that reason, Qt supplies the QListView widget, which allows more varied items to be created. It is a pure presentation widget, which displays information provided by a data model.

For a widget application using PySide2, you must always start by importing the appropriate class from the PySide2.QtWidgets module. After the imports, you create a QApplication instance. As Qt can receive arguments from command line, you may pass any argument to the QApplication object. Nov 07, 2018 · This tutorial uses a simple example of QLCDNumber and QDial. The steps start with create the QWidget with the QLCDNumber and QDial. You need to set geometry for both and connect the dial with valueChanged. Finally you need to use show to see the QWidget. The result is show into the next screenshot: Let see the source code: PySide2 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 to work with Qt 5 instead of Qt 4. It is one of the alternatives to the standard library package Tkinter .
