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 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.
