GDesktopAppInfo is an implementation of GAppInfo based on desktop files.
Note that <gio/gdesktopappinfo.h> belongs to
the UNIX-specific GIO interfaces, thus you have to use the
gio-unix-2.0.pc pkg-config file when using it.
typedef struct _GDesktopAppInfo GDesktopAppInfo;
Information about an installed application from a desktop file.
GDesktopAppInfo * g_desktop_app_info_new_from_filename
(const char *filename);
Creates a new GDesktopAppInfo.
|
the path of a desktop file, in the GLib filename encoding |
Returns : |
a new GDesktopAppInfo or NULL on error. |
GDesktopAppInfo * g_desktop_app_info_new_from_keyfile (GKeyFile *key_file);
Creates a new GDesktopAppInfo.
|
an opened GKeyFile |
Returns : |
a new GDesktopAppInfo or NULL on error. |
Since 2.18
GDesktopAppInfo * g_desktop_app_info_new (const char *desktop_id);
Creates a new GDesktopAppInfo based on a desktop file id.
A desktop file id is the basename of the desktop file, including the
.desktop extension. GIO is looking for a desktop file with this name
in the applications subdirectories of the XDG data
directories (i.e. the directories specified in the
XDG_DATA_HOME and XDG_DATA_DIRS environment
variables). GIO also supports the prefix-to-subdirectory mapping that is
described in the Menu Spec
(i.e. a desktop id of kde-foo.desktop will match
/usr/share/applications/kde/foo.desktop).
|
the desktop file id |
Returns : |
a new GDesktopAppInfo, or NULL if no desktop file with that id |
const char * g_desktop_app_info_get_filename (GDesktopAppInfo *info);
When info was created from a known filename, return it. In some
situations such as the GDesktopAppInfo returned from
g_desktop_app_info_new_from_keyfile(), this function will return NULL.
|
a GDesktopAppInfo |
Returns : |
The full path to the file for info, or NULL if not known. |
Since 2.24
gboolean g_desktop_app_info_get_is_hidden (GDesktopAppInfo *info);
A desktop file is hidden if the Hidden key in it is set to True.
|
a GDesktopAppInfo. |
Returns : |
TRUE if hidden, FALSE otherwise. |
gboolean g_desktop_app_info_get_nodisplay (GDesktopAppInfo *info);
Gets the value of the NoDisplay key, which helps determine if the
application info should be shown in menus. See
G_KEY_FILE_DESKTOP_KEY_NO_DISPLAY and g_app_info_should_show().
|
a GDesktopAppInfo |
Returns : |
The value of the NoDisplay key |
Since 2.30
gboolean g_desktop_app_info_get_show_in (GDesktopAppInfo *info,const gchar *desktop_env);
Checks if the application info should be shown in menus that list available
applications for a specific name of the desktop, based on the
OnlyShowIn and NotShowIn keys.
If desktop_env is NULL, then the name of the desktop set with
g_desktop_app_info_set_desktop_env() is used.
Note that g_app_info_should_show() for info will include this check (with
NULL for desktop_env) as well as additional checks.
|
a GDesktopAppInfo |
|
a string specifying a desktop name |
Returns : |
TRUE if the info should be shown in desktop_env according to the
OnlyShowIn and NotShowIn keys, FALSE
otherwise. |
Since 2.30
const char * g_desktop_app_info_get_generic_name (GDesktopAppInfo *info);
Gets the generic name from the destkop file.
|
a GDesktopAppInfo |
Returns : |
The value of the GenericName key |
const char * g_desktop_app_info_get_categories (GDesktopAppInfo *info);
Gets the categories from the desktop file.
|
a GDesktopAppInfo |
Returns : |
The unparsed Categories key from the desktop file; i.e. no attempt is made to split it by ';' or validate it. |
const char * const * g_desktop_app_info_get_keywords (GDesktopAppInfo *info);
Gets the keywords from the desktop file.
|
a GDesktopAppInfo |
Returns : |
The value of the X-GNOME-Keywords key |
Since 2.32
void g_desktop_app_info_set_desktop_env (const char *desktop_env);
Sets the name of the desktop that the application is running in.
This is used by g_app_info_should_show() and
g_desktop_app_info_get_show_in() to evaluate the
OnlyShowIn and NotShowIn
desktop entry fields.
The Desktop Menu specification recognizes the following:
| GNOME |
| KDE |
| ROX |
| XFCE |
| LXDE |
| Unity |
| Old |
Should be called only once; subsequent calls are ignored.
|
a string specifying what desktop this is |
void (*GDesktopAppLaunchCallback) (GDesktopAppInfo *appinfo,GPid pid,gpointer user_data);
During invocation, g_desktop_app_info_launch_uris_as_manager() may
create one or more child processes. This callback is invoked once
for each, providing the process ID.
|
a GDesktopAppInfo |
|
Process identifier |
|
User data |
gboolean g_desktop_app_info_launch_uris_as_manager (GDesktopAppInfo *appinfo,GList *uris,GAppLaunchContext *launch_context,GSpawnFlags spawn_flags,GSpawnChildSetupFunc user_setup,gpointer user_setup_data,GDesktopAppLaunchCallback pid_callback,gpointer pid_callback_data,GError **error);
This function performs the equivalent of g_app_info_launch_uris(),
but is intended primarily for operating system components that
launch applications. Ordinary applications should use
g_app_info_launch_uris().
In contrast to g_app_info_launch_uris(), all processes created will
always be run directly as children as if by the UNIX fork()/exec()
calls.
This guarantee allows additional control over the exact environment
of the child processes, which is provided via a setup function
user_setup, as well as the process identifier of each child process
via pid_callback. See g_spawn_async() for more information about the
semantics of the user_setup function.
