I recently decided to start putting together some fun example desktop applications using Python. I’ve been using wxPython to create the cross platform applications. My first one is called Boomslang XML and is a basic XML editor. The name, Boomslang, comes from a large venomous snake. It’s name basically means “tree snake”, which I thought

Most applications come with the Status Bar. The status bar is the widget along the bottom of most applications that you use every day. They give you information about what line you’re editing in a text editor or when you last saved. In wxPython, you can add a status bar to your frame by using

The wxPython GUI toolkit comes with many widgets. A common control is a tree widget. wxPython has several different tree widgets, including the regular wx.TreeCtrl, the newer DVC_TreeCtrl and the pure Python variants, CustomTreeCtrl and HyperTreeList. In this article, we will focus on the regular wx.TreeCtrl and learn the basics of how to create and

I stumbled across the pywebview project a couple of weeks ago. The pywebview package “is a lightweight cross-platform wrapper around a webview component that allows to display HTML content in its own native GUI window.” It uses WebKit on OSX and Linux and Trident (MSHTML) on Windows, which is actually what wxPython’s webview widget also

The wxPython project made a major announcement over the weekend in releasing an alpha version of the new wxPython “Phoenix” package to the Python Packaging Index (PyPI). wxPython is a major cross-platform desktop graphics user interface toolkit for Python. It wraps wxWidgets and is one of the major competitors to PyQt. All new releases of

The Python programming language has several built-in types that it supports. One of my favorites is the dictionary. A dictionary is a mapping object maps hashable values to arbitrary objects (source). Other languages call dictionaries “hash tables”. They are mutable objects that you can change whenever you want to, unlike tuples. A dictionary’s keys must

Last week I was doing some Test Driven Development training and overheard someone mention another programming language that had a test runner that you could set up to watch your project directory and run your tests when the files changed. I thought that was a neat idea. I also thought I could easily write my

Over the summer, I came across an interesting plotting library called GooPyCharts which is a Python wrapper for the Google Charts API. In this article, we will spend a few minutes learning how to use this interesting package. GooPyCharts follows syntax that is similar to MATLAB and is actually meant to be an alternative to

For the past couple of years, I’ve been writing automated tests for my employer. One of the many types of tests that I do is comparing how an application draws. Does it draw the same way every single time? If not, then we have a serious problem. An easy way to check that it draws

The Python Imaging Library or PIL allowed you to do image processing in Python. The original author, Fredrik Lundh, wrote one of my favorite Python blogs when I first started learning Python. However PIL’s last release was way back in 2009 and the blog also stopped getting updated. Fortunately, there were some other Python folks

I recently started using twisted a couple of weeks ago. For those who don’t know, twisted is “event-driven networking engine written in Python”. The learning curve is pretty steep if you’ve never done asynchronous programming before. During the project I was working on, I ran into a condition where I thought I needed to restart

The concurrent.futures module was added in Python 3.2. According to the Python documentation it provides the developer with a high-level interface for asynchronously executing callables. Basically concurrent.futures is an abstraction layer on top of Python’s threading and multiprocessing modules that simplifies using them. However it should be noted that while the abstraction layer simplifies the
