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.

Implementing highlighting in StyledTextCtrl


The StyledTextCtrl provides a vast number of built-in lexers to provide syntax highlighting of various types of programming languages. Its API also allows us to extend these capabilities by providing our own custom styling of text in the buffer. This can be useful to create a text editor for your own custom markup or for special text formatting. In this recipe, we will take a look at how to implement custom text styling in StyledTextCtrl.

Getting ready

If you haven't already, you may want to jump back and take a look at the other StyledTextCtrl recipes in Chapter 4, Containers and Advanced Controls, to get some familiarity with StyledTextCtrl prior to continuing with this recipe.

  1. First, we need to import the wx.stc submodule and define a couple of IDs to use for our custom lexer's different styles, as follows:

    import wx
    import wx.stc as stc
    
    # Style IDs for the KeywordLexer
    STC_STYLE_KW_DEFAULT, \
    STC_STYLE_KW_KEYWORD...
