wxPython Application Development Cookbook

By: Cody Precord

Overview of this book

wxPython is a GUI toolkit for the Python programming language built on top of the cross-platform wxWidgets GUI libraries. wxPython provides a powerful set of tools that allow you to quickly and efficiently building applications that can run on a variety of different platforms. Since wxWidgets provides a wrapper around each platform’s native GUI toolkit, the applications built with wxPython will have a native look and feel wherever they are deployed. This book will provide you with the skills to build highly functional and native looking user interfaces for Python applications on multiple operating system environments. By working through the recipes, you will gain insights into and exposure to creating applications using wxPython. With a wide range of topics covered in the book, there are recipes to get the most basic of beginners started in GUI programming as well as tips to help experienced users get more out of their applications. The recipes will take you from the most basic application constructs all the way through to the deployment of complete applications.

Displaying dynamic data


In the previous two recipes in this chapter, we looked at how to work with GridTableBase to make a data source and considered some additional information about grid itself. In these previous examples, we worked with static data that was preloaded into the data table; however, in this recipe, we will work with a dynamic data source that can update grid dynamically when the data in the data source changes.

How to do it…

Perform the following steps for this recipe:

  1. First, let's import all the libraries we will need for this recipe, which are as follows:

    import os
    import stat
    import time
    import wx
    import wx.grid as gridlib
  2. Next, let's start by making a little data class to help put information about a file in a human readable format:

    class FileInfo:
        def __init__(self, path):
            self.path = path
            fstat = os.stat(path)
            ltime = time.localtime(fstat[stat.ST_MTIME])
            self.modified = time.asctime(ltime)
            self.type = "Directory" if os.path.isdir...
