//! \brief The QsciAPIs class provies an implementation of the textual API
|
||||
//! information used in call tips and for auto-completion.
|
||||
//!
|
||||
//! Raw API information is read from one or more files. Each API function is
|
||||
//! described by a single line of text comprising the function's name, followed
|
||||
//! by the function's optional comma separated parameters enclosed in
|
||||
//! parenthesis, and finally followed by optional explanatory text.
|
||||
//!
|
||||
//! A function name may be followed by a `?' and a number. The number is used
|
||||
//! by auto-completion to display a registered QPixmap with the function name.
|
||||
//!
|
||||
//! All function names are used by auto-completion, but only those that include
|
||||
//! function parameters are used in call tips.
|
||||
//!
|
||||
//! QScintilla only deals with prepared API information and not the raw
|
||||
//! information described above. This is done so that large APIs can be
|
||||
//! handled while still being responsive to user input. The conversion of raw
|
||||
//! information to prepared information is time consuming (think tens of
|
||||
//! seconds) and implemented in a separate thread. Prepared information can
|
||||
//! be quickly saved to and loaded from files. Such files are portable between
|
||||
//! different architectures.
|
||||
//!
|
||||
//! QScintilla based applications that want to support large APIs would
|
||||
//! normally provide the user with the ability to specify a set of, possibly
|
||||
//! project specific, raw API files and convert them to prepared files that are
|
||||
//! loaded quickly when the application is invoked.
