Using Wing with wxPython

Wing Pro Screenshot

Wing is a Python IDE that can be used to develop, test, and debug Python code written for the wxPython cross-platform GUI development toolkit.

Two versions of Wing are appropriate for use with this document: Wing Pro is the full-featured Python IDE for professional developers, and Wing Personal is a free alternative with reduced feature set.

If you do not already have Wing installed, download it now.

This document describes how to configure Wing for wxPython. To get started using Wing as your Python IDE, please refer to the tutorial in Wing's Help menu or read the Quickstart Guide.


wxPython is a good choice for desktop application developers that want to use Python. It is available for Windows, Linux, and Mac OS X and provides native look and feel on each of these platforms.

While Wing does not provide a GUI builder for wxPython, it does provide advanced editing, debugging, testing, and code inspection capabilities for Python, and it can be used with other available GUI builders, as described below.

Installation and Configuration

Take the following steps to set up and configure Wing for use with wxPython:

  • Install wxPython as described on the wxPython Downloads page. Be sure to install also the wxPython demo and samples.
  • Install Wing if you don't already have it.
  • Start Wing from the Start menu on Windows, the Finder or OS X, or by typing wing7.0 on the command line on Linux.
  • Select Show Python Environment from the Source menu. If the Python version reported there doesn't match the one you're using with wxPython, then select Project Properties from the Project menu and set Python Executable to the full path of Python interpreter into which you installed wxPython. This value can be found by running Python outside of Wing and executing the following commands interactively:

    import sys
  • Locate and open wxPython's into Wing and then select Add Current File from the Project menu to add it to your project. If you can't find but have other wxPython code that works, you can just use that. However, you'll need to adapt the instructions in the rest accordingly.
  • Set as main entry point for debugging using the Set Current as Main Entry Point item in the Debug menu.
  • Save your project to disk. Use a name ending in .wpr.

Test Driving the Debugger

Now you're ready to try out the debugger:

Start debugging with the Start / Continue item in the Debug menu. Uncheck the Show this dialog before each run checkbox at the bottom of the dialog that appears and select OK.

The demo application will start up. If its main window doesn't come to front, bring it to front from your task bar or window manager. Try out the various demos from the tree on the left of the wxPython demo app.

Next open, located in the same directory as Set a breakpoint on the first line of runTest() by clicking on the dark grey left margin. Go into the running demo app and select More Dialogs / ImageBrowser. Wing will stop on your breakpoint.

From here, you can step through code or inspect the program state with Stack Data and other tools. In Wing Pro, the Debug Console provides a command line that allows you to interact with the current stack frame in your debug process. All the debugging tools are available from the Tools menu.

See the Wing Tutorial and Quick start for more information.

Using a GUI Builder

Wing doesn't include a GUI builder for wxPython but it can be used with other tools, such as wxGlade or wxFormBuilder. Wing will automatically reload files that are generated by the GUI builder.
