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.

Selecting files with FileDialog


Many applications operate on files as their input and output; FileDialog is the standard way to allow users to either choose files to open or input a file path to save the current document on. In this recipe, we will take a look at how to use FileDialog to open and save text files.

Getting ready

This recipe will add the Open and Save functionalities to the text editor application that we started back in Chapter 2, Common User Controls. It only covers the functionality of FileDialog, but you may want to jump back to the Exploring menus and shortcuts and Working with ToolBars recipes from Chapter 2, Common User Controls, for a refresher on how the base code in this recipe is started.

How to do it…

Perform the following steps:

  1. First, let's start by importing the needed modules and overriding the base class' constructor, as follows:

    import wx
    
    # Code from Chapter 2 Working with Toolbars
    import chapter2Editor as c2e
    
    class FileEditor(c2e.EditorWithToolBar):
        def __init__...
