An article about wxPython, one of the most popular desktop graphical user interface (GUI) toolkits for the Python programming language
Today we’re going to learn about one of wxPython’s newer features: wx.lib.softwareupdate. It was actually added a couple of years ago. What this allows you to do is add update abilities to your software. As far as I can tell, this mixin only allows prompted updates, not silent updates. Getting Started It’s built into wxPython […]

This topic comes up from time to time every year. Someone will ask about how to make their application full screen or how to just make it maximize when it first loads. So we’ll spend a little time showing you how to do each of these activities.

I sometimes run into situations where it would be nice to have one of my Python scripts communicate with another of my Python scripts. For example, I might want to send a message from a command-line script that runs in the background to my wxPython GUI that’s running on the same machine. I had heard

This week, I needed to figure out how to attach an event handler that would fire when I double-clicked an item (i.e. row) in an ObjectListView widget that was in LC_REPORT mode. For some reason, there isn’t an obvious mouse event for that. There is an EVT_LIST_ITEM_RIGHT_CLICK and an EVT_LIST_ITEM_MIDDLE_CLICK, but nothing for LEFT clicks

This week I spent some time learning how to add check boxes to the ObjectListView widget in wxPython. If you don’t know, ObjectListView is a 3rd party wrapper for the wx.ListCtrl widget that makes using the ListCtrl much easier. You can read all about it in this older article from the archives. I had a

The other day, I stumbled across a question on StackOverflow asking how to get the children widgets of a BoxSizer. In wxPython, you would expect to call the sizer’s GetChildren() method. However, this returns a list of SizerItems objects rather than a list of the actual widgets themselves. You can see the difference if you

People keep on asking fun wxPython questions on StackOverflow. Today they wanted to know how to make “flashing text” in wxPython. That’s actually a pretty easy thing to do. Let’s take a look at some simple code: import random import time import wx ######################################################################## class MyPanel(wx.Panel): “””””” #———————————————————————- def __init__(self, parent): “””Constructor””” wx.Panel.__init__(self, parent) self.font

Today on StackOverflow I saw someone who wanted to know how to drag a file from a wx.ListCtrl onto their Desktop or somewhere else in the file system. They were using the file manager skeleton from zetcode, but couldn’t figure out how to add the DnD portion. After a bit of searching and hacking, I

Occasionally I’ll see someone on the wxPython users group ask about how to make the wx.Notebook change pages (or tabs) programmatically. So I decided it was about time I figured it out. Here is some code that works for me: import random import wx ######################################################################## class TabPanel(wx.Panel): #———————————————————————- def __init__(self, parent, page): “””””” wx.Panel.__init__(self, parent=parent)

This week, I came across a fun Python project named psutil on Google Code. It says it works on Linux, Windows, OSX and FreeBSD. What it does is grab all the running processes and gives you information on them and also gives you the ability to terminate them. So I thought it would be fun

The other day on StackOverflow I saw someone who was struggling with the Wizard widget from wxPython. The wizard doesn’t allow much customization when it comes to its buttons, so I decided to see how hard it would be to just write my own Wizard. This code is pretty limited, but here’s my first beta

My long time readers may remember me mentioning that I was trying to put my article code into a Mercurial repository on bitbucket. I haven’t been doing a very good job of that lately, but I did decide to release a whole bunch of wxPython example scripts on there. I use them a lot when

I meant to write up a post on this within a week of reading about it, but then things got busy and I forgot. Anyway, there’s a new widget in the wxPython toolkit called the ShortcutEditor. You can read about it on the wxPython mailing list. You’ll probably have to update the agw lib folder

Most computer users of this day and age use drag and drop (DnD) instinctively. You probably used it to transfer some files from one folder to another this week! The wxPython GUI toolkit provides drag and drop functionality baked in. In this tutorial, we’ll see just how easy it is to implement!
