gnome-session needs to know the startup id that was given to a started app; this was not available via GAppLaunchContext. This commit adds a ::launched signal to get this information. At the same time, turn the launch_failed vfunc into a signal as well. https://bugzilla.gnome.org/show_bug.cgi?id=688497

/**

|
* SECTION:gappinfo
|
|
* @short_description: Application information and launch contexts
|
|
* @include: gio/gio.h
|
|
*
|
|
* #GAppInfo and #GAppLaunchContext are used for describing and launching
|
|
* applications installed on the system.
|
|
*
|
|
* As of GLib 2.20, URIs will always be converted to POSIX paths
|
|
* (using g_file_get_path()) when using g_app_info_launch() even if
|
|
* the application requested an URI and not a POSIX path. For example
|
|
* for an desktop-file based application with Exec key <literal>totem
|
|
* %U</literal> and a single URI,
|
|
* <literal>sftp://foo/file.avi</literal>, then
|
|
* <literal>/home/user/.gvfs/sftp on foo/file.avi</literal> will be
|
|
* passed. This will only work if a set of suitable GIO extensions
|
|
* (such as gvfs 2.26 compiled with FUSE support), is available and
|
|
* operational; if this is not the case, the URI will be passed
|
|
* unmodified to the application. Some URIs, such as
|
|
* <literal>mailto:</literal>, of course cannot be mapped to a POSIX
|
|
* path (in gvfs there's no FUSE mount for it); such URIs will be
|
|
* passed unmodified to the application.
|
|
*
|
|
* Specifically for gvfs 2.26 and later, the POSIX URI will be mapped
|
|
* back to the GIO URI in the #GFile constructors (since gvfs
|
|
* implements the #GVfs extension point). As such, if the application
|
|
* needs to examine the URI, it needs to use g_file_get_uri() or
|
|
* similar on #GFile. In other words, an application cannot assume
|
|
* that the URI passed to e.g. g_file_new_for_commandline_arg() is
|
|
* equal to the result of g_file_get_uri(). The following snippet
|
|
* illustrates this:
|
|
*
|
|
* <programlisting>
|
|
* GFile *f;
|
|
* char *uri;
|
|
*
|
|
* file = g_file_new_for_commandline_arg (uri_from_commandline);
|
|
*
|
|
* uri = g_file_get_uri (file);
|
|
* strcmp (uri, uri_from_commandline) == 0; // FALSE
|
|
* g_free (uri);
|
|
*
|
|
* if (g_file_has_uri_scheme (file, "cdda"))
|
|
* {
|
|
* // do something special with uri
|
|
* }
|
|
* g_object_unref (file);
|
|
* </programlisting>
|
|
*
|
|
* This code will work when both <literal>cdda://sr0/Track
|
|
* 1.wav</literal> and <literal>/home/user/.gvfs/cdda on sr0/Track
|
|
* 1.wav</literal> is passed to the application. It should be noted
|
|
* that it's generally not safe for applications to rely on the format
|
|
* of a particular URIs. Different launcher applications (e.g. file
|
|
* managers) may have different ideas of what a given URI means.
|
