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 always spend some time thinking about how I want my book’s cover to look. When I was designing the Cookbook’s cover, I thought mostly about food and chefs. I had originally thought I might have some kind of kitchen scene with mice in chef hats and a snake on the mantle. But I wanted

The wxPython toolkit added context managers to its code base a few years ago, but for some reason you don’t see very many examples of their use. In this article, we’ll look at three examples of context managers in wxPython. A wxPython user was the first person to suggest using context managers in wxPython on

The other day, I came across an interesting StackOverflow question where the fellow was trying to figure out how to open a sub-frame only once. Basically he wanted a single instance of the sub-frame (and other sub-frames). After digging around a bit on Google, I found an old thread from the wxPython Google Group that

I recently came across a StackOverflow question where the fellow was asking how to get wxPython’s RichTextCtrl’s XML data so he could save it to a database. I don’t know much about this control, but after a quick Google search, I found an article from 2008 that gave me the information I needed. I took

I recently came across a fun little project called EasyGUI_Qt. It’s basically the same thing as EasyGUI except that it uses PyQt4 instead of Tkinter. The idea behind both of these packages is to allow the developer to ask the user simple questions using dialogs. In this article, we’ll spend some time learning how to

The wxPython library comes with a pair of handy methods called Freeze() and Thaw(). The call to Freeze() prevents the window from updating while it is frozen. This can be useful when you are adding or removing widgets and you want to reduce your UI from appearing to flicker. After you finish updating the UI,

The wxPython GUI toolkit includes its own date / time capabilities. Most of the time, you can just use Python’s datetime and time modules and you’ll be fine. But occasionally you’ll find yourself needing to convert from wxPython’s wx.DateTime objects to Python’s datetime objects. You may encounter this when you use the wx.DatePickerCtrl widget. Fortunately,

Redirecting stdout seems to be a pretty common request on the wxPython users group, so I decided to see how easy it would be to do it with Tkinter. The typical use case for redirecting stdout or stderr is that you are calling some other process (like ping or tracert) and you want to catch

I’ve been using wxPython for quite a while now and I see certain questions come up on a fairly frequent basis. One of the popular ones is how to ask the user for their credentials before loading up the rest of the application. There are several approaches to this, but I am going to focus
