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.

Using Print dialogs


Adding printing support to an application can be a difficult task, as there are a number of tasks that need to be handled. These include selecting and configuring a printer, translating your on-screen presentation to paper and ultimately sending the data to the printer.

In wxPython, there are three dialog classes related to printing: PageSetupDialog, PreviewFrame, and Printer. In addition to these, there are a number of supporting classes that must be used in conjunction with these dialogs in order to add printing support to an application. This recipe shows some of the basics of how to use the wxPython printing framework by creating a class that encapsulates the usage of the three printing dialogs and allows an application to print a bitmap.

How to do it…

Here are the steps to perform in this recipe:

  1. First, we will make a subclass of wx.Printout. This object is used by the print framework to control how the printout is rendered to the media, as follows:

    class BitmapPrintout...
