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 The shellQuote() function quotes a string suitable for passing to a shell. The stringQuote() function backslash escapes '\' and '"' characters. \section1 Hardware The implementation of the writeHWClock() function depends on the AlarmServer implementation. If the AlarmServer is using atd the clock will be synced to hardware. If opie-alarm is used the hardware clock will be synced before suspending the device. opie-alarm is used by iPAQ and Zaurii implementation \ingroup qtopiaemb */ /*! \internal */ Global::Global() { } /*!
