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().
