Generic wrappers

edit

Generic GUI/API wrappers are programming libraries that provide a uniform platform neutral interface (API) to the operating system regardless of underlying platform. Such libraries greatly simplify development of cross-platform software.

Using a wrapper as a portability layer will offer applications some or all following benefits:

  • Independence from the hardware.
  • Independence from the Operating System.
    • Independence from changes made to specific releases.
    • Independence from API styles and error codes.

Cross-platform programming is more than only GUI programming. Cross-platform programming deals with the minimum requirements for the sections of code that aren't specified by the C++ Standard Language, so as programs can be compiled and run across different hardware platforms.

Here is some cross-platform GUI toolkit:

  • Gtkmm - an interface for the C GUI library GTK+. It is not cross-platform by design, but rather multi-platform i.e. can be used on many platform.
  • Qt (http://qt-project.org) - a cross-platform (Qt is the basis for the Linux KDE desktop environment and supports the X Window System (Unix/X11), Apple Mac OS X, Microsoft Windows NT/9x/2000/XP/Vista/7 and the Symbian OS), it is an object-oriented application development framework, widely used for the development of GUI programs (in which case it is known as a widget toolkit), and for developing non-GUI programs such as console tools and servers. Used in numerous commercial applications such as Google Earth, Skype for Linux and Adobe Photoshop Elements. Released under the LGPL or a commercial license.
  • wxWidgets (http://wxwidgets.org/) - a widget toolkit for creating graphical user interfaces (GUIs) for cross-platform applications on Win32, Mac OS X, GTK+, X11, Motif, WinCE, and more using one codebase. It can be used from languages such as C++, Python, Perl, and C#/.NET. Unlike other cross-platform toolkits, wxWidgets applications look and feel native. This is because wxWidgets uses the platform's own native controls rather than emulating them. It's also extensive, free, open-source, and mature. wxWidgets is more than a GUI development toolkit it provides classes for files and streams, application settings, multiple threads, interprocess communication, database access and more.
  • FLTK The "Fast, Light Toolkit"
