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(). \ingroup qtopiaemb */ /*! Sets the size used for small icons to \a small pixels. Only affects AppLnk objects created after the call. |
