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 transient notifications


If your application needs to occasionally get the user's attention and present some information that may not be critical or require acknowledgement, the ToasterBox window can be a nice and unobtrusive way to show simple messages to the user. In this recipe, we will make a small TrayIcon application that acts as a timer, which pops up a notification every time a set amount of time has elapsed.

How to do it…

Here are the steps that you need to perform:

  1. First, we need an additional import from wx.lib to access ToasterBox. For this, we will uses the following code:

    import wx
    import wx.lib.agw.toasterbox as tb
    
    ID_GET_DUR = wx.NewId()
    ID_START = wx.NewId()
  2. Next, let's make a custom TaskBarIcon object to manage our alarm notifications, as follows:

    class AlarmIcon(wx.TaskBarIcon):
        def __init__(self, topWindow):
            super(AlarmIcon, self).__init__()
    
            self._topWindow = topWindow
            self._timer = wx.Timer(self)
            self._duration = 10
    
           ...
