   \class AppLnk applnk.h
   \brief The AppLnk class represents an application available on the system.
 
     Every Qtopia application \e app has a corresponding \e app.desktop
     file. When one of these files is read its data is stored as an
     AppLnk object.
 
     The AppLnk class introduces some Qtopia-specific concepts, and
     provides a variety of functions, as described in the following
     sections.
     \tableofcontents
 
     \target Types
     \section1 Types
 
     Every AppLnk object has a \e type. For applications, games and
     settings the type is \c Application; for documents the
     type is the document's MIME type.
 
     \target files-and-links
     \section1 Files and Links
 
     When you create an AppLnk (or more likely, a \link doclnk.html
     DocLnk\endlink), you don't deal directly with filenames in the
     filesystem. Instead you do this:
     \code
     DocLnk d;
     d.setType("text/plain");
     d.setName("My Nicely Named Document / Whatever"); // Yes, "/" is legal.
     \endcode
     At this point, the file() and linkFile() are unknown. Normally
     this is uninteresting, and the names become automatically known,
     and more importantly, becomes reserved, when you ask what they are:
 
     \code
     QString fn = d.file();
     \endcode
     This invents a filename, and creates the file on disk (an empty
     reservation file) to prevent the name being used by another
     application.
 
     In some circumstances, you don't want to create the file if it
     doesn't already exist (e.g. in the Document tab, some of the \link
     doclnk.html DocLnk\endlink objects represented by icons are
     DocLnk's created just for that view - they don't have
     corresponding \c .desktop files. To avoid littering empty
     reservation files around, we check in a few places to see whether
     the file really needs to exist).
 
     \section1 Functionality
 
     AppLnk objects are created by calling the constructor with the
     name of a \e .desktop file. The object can be checked for validity
     using isValid().
 
     The following functions are used to set or retrieve information
     about the application:
     \table
     \header \i Get Function \i Set Function \i Short Description
             \row \i \l name()    \i \l setName()    \i application's name
             \row \i \l pixmap()     \i \e none    \i application's icon
             \row \i \l bigPixmap()  \i \e none    \i application's large icon
             \row \i \e none    \i setIcon()    \i sets the icon's filename
             \row \i \l type()     \i \l setType()    \i see \link #Types Types\endlink above
             \row \i \l rotation()   \i \e none    \i 0, 90, 180 or 270 degrees
     \row \i \l comment()    \i \l setComment() \i text for the Details dialog
             \row \i \l exec()    \i \l setExec()    \i executable's filename
             \row \i \l file()       \i \e none    \i document's filename
             \row \i \l linkFile()   \i \l setLinkFile()\i \e .desktop filename
             \row \i \l mimeTypes()  \i \e none    \i the mime types the application can view or edit
             \row \i \l categories() \i \l setCategories()\i \e{see the function descriptions}
             \row \i \l fileKnown()  \i \e none    \i see \link
 #files-and-links Files and Links\endlink above
             \row \i \l linkFileKnown() \i \e none    \i see \link
 #files-and-links Files and Links\endlink above
             \row \i \l property()   \i \l setProperty()\i any AppLnk property
     can be retrieved or set (if writeable) using these
     \endtable
 
     To save an AppLnk to disk use writeLink(). To execute the
     application that the AppLnk object refers to, use execute().
 
     AppLnk's can be deleted from disk using removeLinkFile(). To
     remove both the link and the application's executable use
     removeFiles().
 
     Icon sizes can be globally changed (but only for AppLnk objects
     created after the calls) with setSmallIconSize() and
     setBigIconSize().
