The graphical user interface of Audacity is implemented using wxWidgets

wxWidgets (formerly wxWindows ) is an open source GUI toolkit for developing graphical user interfaces . It is developed in the programming language C ++ and licensed under a modified LGPL , which also allows the distribution of derived works under its own conditions. Although wxWidgets is implemented in C ++, there are connections for a large number of other programming languages. Thanks to its platform independence, wxWidgets enables the GUI-specific code of a program to be compiled and executed on a wide variety of platforms with little or no modification.

wxWidgets is used in a number of well-known projects, for example the audio editor Audacity , the strategy game 0 AD , the FTP client FileZilla , the Code :: Blocks development environment and, in the past, Bitcoin Core .


The programming interface enables the development of GUI programs for Windows , Unix , Mac , Symbian OS , Palm OS and Windows CE . wxWidgets abstracts platform-dependent functions, for example interprocess communication (IPC), and offers additional functions, for example a hash table . Some functions such as wxMetafile or OLE are implemented individually in wxWidgets for the respective platform. For better portability wxWidgets waived exceptions (English: exceptions ) and templates . The API includes over 450 classes with over 5000 functions. The most important functionalities cover the following areas:

  • Direct graphic output
  • Platform- independent GUI layout (sizer layout)
  • GUI resources (XRC) are ported via XML
  • Online documentation (e.g. HTML , CHM )
  • Unicode and message catalogs
  • Platform-independent graphic format: XPM
  • Very powerful wxImage class
  • Machine-independent stream class
  • C ++ typical container / data classes
  • MIME Types Manager
  • OLE automation
  • Multithreading
  • Configuration via file, Windows registry or * .ini


In 1992 the first edition appeared, which was for XView and MFC .

From 1993 to 1995 Motif , the Xt port and wxPython were developed and published. From 1998 to 2002 wx GTK Port was used, wx Mac 2.0 Port, wx X11 Port and OS / 2 Port started.

In 2003 the wxWidgets Software Foundation was founded, which was dissolved after a few months. A year later wxWindows was renamed wxWidgets at the request and payment of Microsoft .

In 2005 wxWidgets 2.6.0 was released. It replaced the previous stable version 2.4.2 from mid-2003. Version 2.8.0 was released at the end of 2006, version 2.9.0 was released in September 2009.
