The concept is that GUI widgets can send signals containing event information which can be received by other controls using special functions known as slots. The signal/slot system fits well with the way Graphical User Interfaces are designed. Similarly, the signal/slot system can be used for other non-GUI usages, for example asynchronous I/O (including sockets, pipes, serial devices, etc.) event notification or to associate timeout events with appropriate object instances and methods or functions. It is easy to use and no registration/deregistration/invocation code need to be written, because Qt's Meta Object Compiler (MOC) automatically generates the needed infrastructure. A commonly used metaphor is a spreadsheet. A spreadsheet has cells that observe the source cell(s). When the source cell is changed, the dependent cells are updated from the event. ==Alternative implementations== There are some implementations of signal/slot systems based on C++ templates, which don't require the extra Meta Object Compiler, as used by Qt, such as libsigc++, (sigslot ), (nano-signal-slot ), (neosigslot ), (Signals ), (boost.signals2 ), (Cpp::Events ), (Platinum ) and (JBroadcaster ). CLI languages such as C# also supports a similar construct although with a different terminology and syntax: events play the role of signals, and delegates are the slots. Another implementation of signals exists for (ActionScript 3.0 ), inspired by C# events and signals/slots in Qt. Additionally, a delegate can be a local variable, much like a function pointer, while a slot in Qt must be a class member declared as such. Due to the language limitation, there isn't a common implementation for ANSI C, but an environment dependent method was given out, see (c-sigslot ), it has been tested on several platforms, notably the ARM C Compiler, but should support any standard ANSI C compiler. The C based GObject system also provides similar functionality via (GSignal ). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Signals and slots」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
