Python Qt Tutorial Documentation Release 0.0
Python Qt tutorial Documentation Release 0.0 Thomas P. Robitaille Jun 11, 2018 Contents 1 Installing 3 2 Part 1 - Hello, World! 5 3 Part 2 - Buttons and events 7 4 Part 3 - Laying out widgets 9 5 Part 4 - Dynamically updating widgets 13 i ii Python Qt tutorial Documentation, Release 0.0 This is a short tutorial on using Qt from Python. There are two main versions of Qt in use (Qt4 and Qt5) and several Python libraries to use Qt from Python (PyQt and PySide), but rather than picking one of these, this tutorial makes use of the QtPy package which provides a way to use whatever Python Qt package is available. This is not meant to be a completely exhaustive tutorial but just a place to start if you’ve never done Qt development before, and it will be expanded over time. Contents 1 Python Qt tutorial Documentation, Release 0.0 2 Contents CHAPTER 1 Installing 1.1 conda If you use conda to manage your Python environment (for example as part of Anaconda or Miniconda), you can easily install Qt, PyQt5, and QtPy (a common interface to all Python Qt bindings) using: conda install pyqt qtpy 1.2 pip If you don’t make use of conda, an easy way to install Qt, PyQt5, and QtPy is to do: pip install pyqt5 qtpy 3 Python Qt tutorial Documentation, Release 0.0 4 Chapter 1. Installing CHAPTER 2 Part 1 - Hello, World! To start off, we need to create a QApplication object, which represents the overall application: from qtpy.QtWidgets import QApplication app= QApplication([]) You will always need to ensure that a QApplication object exists, otherwise your Python script will terminate with an error if you try and use any other Qt objects. -

For more than 15 years, operational GUIs for accelerator controls and some lab applications for equipment experts have been developed in Java, first with Swing and more CRITERIA FOR SELECTING A NEW GUI recently with JavaFX. In March 2018, Oracle announced that Java GUIs were not part of their strategy anymore [1]. TECHNOLOGY They will not ship JavaFX after Java 8 and there are hints In our evaluation of GUI technologies, we considered that they would like to get rid of Swing as well. the following criteria: This was a wakeup call for us. We took the opportunity • Technical match: suitability for Desktop GUI to reconsider all technical options for developing development and good integration with the existing operational GUIs. Our options ranged from sticking with controls environment (Linux, Java, C/C++) and the JavaFX, over using the Qt framework (either using PyQt APIs to the control system; or developing our own Java Bindings to Qt), to using Web • Popularity among our current and future developers: technology both in a browser and in native desktop little (additional) learning effort, attractiveness for new applications. -

Comparative Studies of Six Programming Languages
Comparative Studies of Six Programming Languages Zakaria Alomari Oualid El Halimi Kaushik Sivaprasad Chitrang Pandit Concordia University Concordia University Concordia University Concordia University Montreal, Canada Montreal, Canada Montreal, Canada Montreal, Canada [email protected] [email protected] [email protected] [email protected] Abstract Comparison of programming languages is a common topic of discussion among software engineers. Multiple programming languages are designed, specified, and implemented every year in order to keep up with the changing programming paradigms, hardware evolution, etc. In this paper we present a comparative study between six programming languages: C++, PHP, C#, Java, Python, VB ; These languages are compared under the characteristics of reusability, reliability, portability, availability of compilers and tools, readability, efficiency, familiarity and expressiveness. 1. Introduction: Programming languages are fascinating and interesting field of study. Computer scientists tend to create new programming language. Thousand different languages have been created in the last few years. Some languages enjoy wide popularity and others introduce new features. Each language has its advantages and drawbacks. The present work provides a comparison of various properties, paradigms, and features used by a couple of popular programming languages: C++, PHP, C#, Java, Python, VB. With these variety of languages and their widespread use, software designer and programmers should to be aware -
