Why C++ is not very fit for GUI programming
<|reference_start|>Why C++ is not very fit for GUI programming: With no intent of starting a holy war, this paper lists several annoying C++ birthmarks that the author has come across developing GUI class libraries. C++'s view of classes, instances and hierarchies appears tantalizingly close to GUI concepts of controls, widgets, window classes and subwindows. OO models of C++ and of a window system are however different. C++ was designed to be a "static" language with a lexical name scoping, static type checking and hierarchies defined at compile time. Screen objects on the other hand are inherently dynamic; they usually live well beyond the procedure/block that created them; the hierarchy of widgets is defined to a large extent by layout, visibility and event flow. Many GUI fundamentals such as dynamic and geometric hierarchies of windows and controls, broadcasting and percolation of events are not supported directly by C++ syntax or execution semantics (or supported as "exceptions" -- pun intended). Therefore these features have to be emulated in C++ GUI code. This leads to duplication of a graphical toolkit or a window manager functionality, code bloat, engaging in unsafe practices and forgoing of many strong C++ features (like scoping rules and compile-time type checking). This paper enumerates a few major C++/GUI sores and illustrates them on simple examples.<|reference_end|>
