wxPython Application Development Cookbook

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.

Modeling your data


The DataViewCtrl control allows a flexible way to display rich data. The DataViewCtrl control can use different data model classes to represent and provide data to the view that can then present the data, such as ListCtrl or TreeCtrl. In this recipe, we will take a look at getting started with DataViewCtrl by creating a custom DataViewModel class to provide data to the control.

How to do it…

Perform the following steps:

  1. First, we need to import an extra module as DataViewCtrl and related classes are in a submodule of the wx namespace:

    import inspect
    import wx
    import wx.dataview as dv
  2. Next, let's define a Python object that will be our data model. This class will be used to represent the structure of class inheritance for a Python object, as follows:

    class HierarchyInfo:
        def __init__(self, item, parent):
            self.item = item
            self.parent = parent
    
            self.name = item.__name__
            self.docs = item.__doc__
            if self.docs:
                self.docs = self...
