>>History

In 1995, Robin Dunn needed a `F33f`_`[GUI`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Graphical_user_interface]`_`f application to be deployed on `F33f`_`[HP-UX`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=HP-UX]`_`f systems but also run `F33f`_`[Windows 3.1`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Windows_3.1]`_`f within short time frame. He needed a `F33f`_`[cross-platform`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Cross-platform_software]`_`f solution. While evaluating free and commercial solutions, he ran across `F33f`_`[Python`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Python_(programming_language)]`_`f bindings on the wxWidgets toolkit `F33f`_`[webpage`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Web_page]`_`f (known as wxWindows at the time). This was Dunn's introduction to Python. Together with Harri Pasanen and Edward Zimmerman he `F33f`_`[developed`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Software_Developer]`_`f those initial bindings into wxPython 0.2.`:cite-ref-0-2-0[`F5bf`_`[2`#cite-note-0-2]`_`f]

In August 1998, version 0.3 of wxPython was released. It was built for wxWidgets 2.0 and ran on Win32, with a wxGTK version in the works.`:cite-ref-3[`F5bf`_`[3`#cite-note-3]`_`f]

The first versions of the wrapper were created by hand. However, the `F33f`_`[code`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Source_code]`_`f became difficult to maintain and keep synchronized with wxWidgets releases. By 1997, versions were created with `F33f`_`[SWIG`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=SWIG]`_`f, greatly decreasing the amount of work to update the wrapper.`:cite-ref-0-2-1[`F5bf`_`[2`#cite-note-0-2]`_`f]

>>>Project Phoenix

In 2010, the Project Phoenix began; an effort to clean up the wxPython `F33f`_`[implementation`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Implementation]`_`f and in the process make it compatible with Python 3.`:cite-ref-4[`F5bf`_`[4`#cite-note-4]`_`f] The project is a new implementation of wxPython, focused on improving speed, maintainability and extensibility. Like the previous version of wxPython, it wraps the wxWidgets `F33f`_`[C++`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=C++]`_`f toolkit and provides access to the `F33f`_`[user interface`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=User_interface]`_`f portions of the wxWidgets `F33f`_`[API`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=API]`_`f.`:cite-ref-5[`F5bf`_`[5`#cite-note-5]`_`f]

With the release of 4.0.0a1 wxPython in 2017, the Project Phoenix version became the official version.`:cite-ref-6[`F5bf`_`[6`#cite-note-6]`_`f] wxPython 4.x is the current version being developed as of June 2022.`:cite-ref-7[`F5bf`_`[7`#cite-note-7]`_`f]

>>Use

wxPython enables Python to be used for `F33f`_`[cross-platform`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Cross-platform_software]`_`f `F33f`_`[GUI`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Graphical_user_interface]`_`f applications requiring very little, if any, platform-specific code.

>>>Example

This is a simple "`F33f`_`[Hello world`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Hello_world_program]`_`f" module, depicting the creation of the two main `F33f`_`[objects`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Object_(computer_science)]`_`f in wxPython (the main window object and the application object), followed by passing the control to the `F33f`_`[event-driven`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Event-driven_programming]`_`f system (by calling `B100`F9d9MainLoop()`f`b) which manages the user-interactive part of the program.

`B100`F9d9#!/usr/bin/env python3`f`b

`B100`F9d9`f`b

`B100`F9d9import wx`f`b

`B100`F9d9`f`b

`B100`F9d9app = wx.App(False) # Create a new app, don't redirect stdout/stderr to a window.`f`b

`B100`F9d9frame = wx.Frame(None, title="Hello World") # A Frame is a top-level window.`f`b

`B100`F9d9frame.Show(True) # Show the frame.`f`b

`B100`F9d9app.MainLoop()`f`b

This is another example of the wxPython Close Button with wxPython GUI display show in Windows 10 operating system.

`B100`F9d9import wx`f`b

`B100`F9d9`f`b

`B100`F9d9class WxButton(wx.Frame):`f`b

`B100`F9d9`f`b

`B100`F9d9 def __init__(self, *args, **kw):`f`b

`B100`F9d9 super(WxButton, self).__init__(*args, **kw)`f`b

`B100`F9d9 self.InitUI()`f`b

`B100`F9d9`f`b

`B100`F9d9 def InitUI(self):`f`b

`B100`F9d9 pnl = wx.Panel(self)`f`b

`B100`F9d9 closeButton = wx.Button(pnl, label='Close Me', pos=(20, 20))`f`b

`B100`F9d9`f`b

`B100`F9d9 closeButton.Bind(wx.EVT_BUTTON, self.OnClose)`f`b

`B100`F9d9`f`b

`B100`F9d9 self.SetSize((350, 250))`f`b

`B100`F9d9 self.SetTitle('Close Button')`f`b

`B100`F9d9 self.Centre()`f`b

`B100`F9d9`f`b

`B100`F9d9 def OnClose(self, e):`f`b

`B100`F9d9 self.Close(True)`f`b

`B100`F9d9`f`b

`B100`F9d9def main():`f`b

`B100`F9d9 app = wx.App()`f`b

`B100`F9d9 ex = WxButton(None)`f`b

`B100`F9d9 ex.Show()`f`b

`B100`F9d9 app.MainLoop()`f`b

`B100`F9d9`f`b

`B100`F9d9if __name__ == "__main__":`f`b

`B100`F9d9 main()`f`b

>>License

Being a wrapper, wxPython uses the same `F33f`_`[free software license`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Free_software_license]`_`f used by `F33f`_`[wxWidgets`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=WxWidgets]`_`f (`F33f`_`[wxWindows License`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=WxWidgets]`_`f)`:cite-ref-8[`F5bf`_`[8`#cite-note-8]`_`f]—which is approved by `F33f`_`[Free Software Foundation`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Free_Software_Foundation]`_`f and `F33f`_`[Open Source Initiative`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Open_Source_Initiative]`_`f.
