The Global functions are grouped as follows: \tableofcontents \section1 User Interface The statusMessage() function provides short-duration messages to the user. The showInputMethod() function shows the current input method, and hideInputMethod() hides the input method. \section1 Document related The findDocuments() function creates a set of \link doclnk.html DocLnk\endlink objects in a particular folder. \section1 Filesystem related Global provides an applicationFileName() function that returns the full path of an application-specific file. The execute() function runs an application. \section1 Word list related A list of words relevant to the current locale is maintained by the system. The list is held in a \link qdawg.html DAWG\endlink (implemented by the QDawg class). This list is used, for example, by the pickboard input method. The global QDawg is returned by fixedDawg(); this cannot be updated. An updatable copy of the global QDawg is returned by addedDawg(). Applications may have their own word lists stored in \l{QDawg}s which are returned by dawg(). Use addWords() to add words to the updateable copy of the global QDawg or to named application \l{QDawg}s. \section1 Quoting @@ -295,458 +295,458 @@ const QDawg& Global::dawg(const QString& name) createDocDir(); if ( !named_dawg ) named_dawg = new QDict<QDawg>; QDawg* r = named_dawg->find(name); if ( !r ) { r = new QDawg; named_dawg->insert(name,r); QString dawgfilename = applicationFileName("Dictionary", name ) + ".dawg"; QFile dawgfile(dawgfilename); if ( dawgfile.open(IO_ReadOnly) ) r->readFile(dawgfilename); } return *r; } /*! \overload Adds \a wordlist to the addedDawg().
