48 : : * GAppInfo:
49 : : *
50 : : * Information about an installed application and methods to launch
51 : : * it (with file arguments).
52 : :
53 : : * `GAppInfo` and `GAppLaunchContext` are used for describing and launching
54 : : * applications installed on the system.
55 : : *
56 : : * As of GLib 2.20, URIs will always be converted to POSIX paths
57 : : * (using [method@Gio.File.get_path]) when using [method@Gio.AppInfo.launch]
58 : : * even if the application requested an URI and not a POSIX path. For example
59 : : * for a desktop-file based application with Exec key `totem
60 : : * %U` and a single URI, `sftp://foo/file.avi`, then
61 : : * `/home/user/.gvfs/sftp on foo/file.avi` will be passed. This will
62 : : * only work if a set of suitable GIO extensions (such as GVfs 2.26
63 : : * compiled with FUSE support), is available and operational; if this
64 : : * is not the case, the URI will be passed unmodified to the application.
65 : : * Some URIs, such as `mailto:`, of course cannot be mapped to a POSIX
66 : : * path (in GVfs there's no FUSE mount for it); such URIs will be
67 : : * passed unmodified to the application.
68 : : *
69 : : * Specifically for GVfs 2.26 and later, the POSIX URI will be mapped
70 : : * back to the GIO URI in the [iface@Gio.File] constructors (since GVfs
71 : : * implements the GVfs extension point). As such, if the application
72 : : * needs to examine the URI, it needs to use [method@Gio.File.get_uri]
73 : : * or similar on [iface@Gio.File]. In other words, an application cannot
74 : : * assume that the URI passed to e.g. [func@Gio.File.new_for_commandline_arg]
75 : : * is equal to the result of [method@Gio.File.get_uri]. The following snippet
76 : : * illustrates this:
77 : : *
78 : : * ```c
79 : : * GFile *f;
80 : : * char *uri;
81 : : *
82 : : * file = g_file_new_for_commandline_arg (uri_from_commandline);
83 : : *
84 : : * uri = g_file_get_uri (file);
85 : : * strcmp (uri, uri_from_commandline) == 0;
86 : : * g_free (uri);
87 : : *
88 : : * if (g_file_has_uri_scheme (file, "cdda"))
89 : : * {
90 : : * // do something special with uri
91 : : * }
92 : : * g_object_unref (file);
93 : : * ```
94 : : *
95 : : * This code will work when both `cdda://sr0/Track 1.wav` and
96 : : * `/home/user/.gvfs/cdda on sr0/Track 1.wav` is passed to the
97 : : * application. It should be noted that it's generally not safe
98 : : * for applications to rely on the format of a particular URIs.
99 : : * Different launcher applications (e.g. file managers) may have
100 : : * different ideas of what a given URI means.

1675 : : * - [func@Gio.AppInfo.get_fallback_for_type]
1676 : : * - [func@Gio.AppInfo.get_recommended_for_type]
1677 : : * - [`g_desktop_app_info_get_implementations()`](../gio-unix/type_func.DesktopAppInfo.get_implementation.html)
1678 : : * - [`g_desktop_app_info_new()`](../gio-unix/ctor.DesktopAppInfo.new.html)
1679 : : * - [`g_desktop_app_info_new_from_filename()`](../gio-unix/ctor.DesktopAppInfo.new_from_filename.html)

1687 : : * In the usual case, applications should try to make note of the change
