\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().
