Working with Frames,long the top that identifies the application. The wx.Frame class allows you to modify its styles in such a way that you can remove or disable various buttons and features. In this chapter, we will look at some of the ways that you can change the behavior of the wx.Frame widget.

Fun with Panels,ime has passed. It was such an interesting idea that I decided to go ahead and write about how to do it. All you really need is a wx.Timer and the panel object. For this piece of code, I used a panel that displays a countdown with a wx.StaticText, destroys itself, and is promptly replaced with another panel.

Working with Sizers,ethod. However, this returns a list of SizerItem objects rather than a list of the actual widgets themselves. You can see the difference if you call a wx.Panel’s GetChildren() method which will actually give you a list of widgets.

Redirecting Text,s logging module write its output to file and to a TextCtrl. It turns out that you need to create a custom logging handler to do it. At first, I tried just using a normal StreamHandler and redirecting stdout via the sys module (sys.stdout) to my text control, but that would only redirect my print statements, not the log messages.

Working with Your Application,In other words, he wanted to be able to edit the code and basically refresh the application without closing it and rerunning his code. The simplest way would be to use Python’s built-in reload() functionality. If we go this route, then we’ll need to build a little front end to import the code that we want to change interactively.

Threads and Timers,p and the user will see your program freeze. This is true of all the Python GUI toolkits, including Tkinter, PyQt, or wxPython. What can you do to get around such mishaps? Start the task in another thread or process, of course! In this chapter, we‘ll look at how to do this with wxPython and Python‘s threading module.
