Class Details¶

class Gio.AppInfo¶

Bases:: GObject.GInterface
Structure:: Gio.AppInfoIface

Information about an installed application and methods to launch it (with file arguments).

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 [method`Gio`.File.get_path]) when using [method`Gio`.AppInfo.launch] even if the application requested an URI and not a POSIX path. For example for a desktop-file based application with Exec key totem %U and a single URI, sftp://foo/file.avi, then /home/user/.gvfs/sftp on foo/file.avi will be passed. This will only work if a set of suitable GIO extensions (such as Gio.Vfs 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 mailto:, of course cannot be mapped to a POSIX path (in Gio.Vfs there’s no FUSE mount for it); such URIs will be passed unmodified to the application.

Specifically for Gio.Vfs 2.26 and later, the POSIX URI will be mapped back to the GIO URI in the [iface`Gio`.File] constructors (since Gio.Vfs implements the Gio.Vfs extension point). As such, if the application needs to examine the URI, it needs to use [method`Gio`.File.get_uri] or similar on [iface`Gio`.File]. In other words, an application cannot assume that the URI passed to e.g. [func`Gio`.File.new_for_commandline_arg] is equal to the result of [method`Gio`.File.get_uri]. The following snippet illustrates this:

```c Gio.File *f; str *uri;

file = Gio.File.new_for_commandline_arg (uri_from_commandline);

uri = Gio.File.get_uri (file); strcmp (uri, uri_from_commandline) == 0; GLib.free (uri);

if (Gio.File.has_uri_scheme (file, “cdda”)) { // do something special with uri } GObject.Object.unref (file); ```

This code will work when both cdda://sr0/Track 1.wav and /home/user/.gvfs/cdda on sr0/Track 1.wav 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.

classmethod create_from_commandline(commandline, application_name, flags)[source]¶

Parameters:

commandline (str) – the commandline to use
application_name (str or None) – the application name, or None to use commandline
flags (Gio.AppInfoCreateFlags) – flags that can specify details of the created Gio.AppInfo

Raises:

GLib.Error

Returns:

new Gio.AppInfo for given command.

Return type:

Gio.AppInfo

Creates a new Gio.AppInfo from the given information.

Note that for commandline, the quoting rules of the Exec key of the freedesktop.org Desktop Entry Specification are applied. For example, if the commandline contains percent-encoded URIs, the percent-character must be doubled in order to prevent it from being swallowed by Exec key unquoting. See the specification for exact quoting rules.

classmethod get_all()[source]¶

Returns:: a newly allocated GLib.List of references to Gio.AppInfos.
Return type:: [Gio.AppInfo]

Gets a list of all of the applications currently registered on this system.

Raises:

GLib.Error

Returns:

True on success, False on error.

Return type:

bool

Utility function that launches the default application registered to handle the specified uri. Synchronous I/O is done on the uri to detect the type of the file if required.

The D-Bus–activated applications don’t have to be started if your application terminates too soon after this function. To prevent this, use Gio.AppInfo.launch_default_for_uri_async() instead.

Parameters:

uri (str) – the uri to show
context (Gio.AppLaunchContext or None) – an optional Gio.AppLaunchContext
cancellable (Gio.Cancellable or None) – a Gio.Cancellable
callback (Gio.AsyncReadyCallback or None) – a Gio.AsyncReadyCallback to call when the request is done
user_data (object or None) – data to pass to callback

Async version of Gio.AppInfo.launch_default_for_uri().

This version is useful if you are interested in receiving error information in the case where the application is sandboxed and the portal may present an application chooser dialog to the user.

This is also useful if you want to be sure that the D-Bus–activated applications are really started before termination and if you are interested in receiving error information from their activation.

New in version 2.50.

classmethod launch_default_for_uri_finish(result)[source]¶

Parameters:: result (Gio.AsyncResult) – a Gio.AsyncResult
Raises:: GLib.Error
Returns:: True if the launch was successful, False if error is set

Finishes an asynchronous launch-default-for-uri operation.

New in version 2.50.

classmethod reset_type_associations(content_type)[source]¶

Parameters:: content_type (str) – a content type

Removes all changes to the type associations done by Gio.AppInfo.set_as_default_for_type(), Gio.AppInfo.set_as_default_for_extension(), Gio.AppInfo.add_supports_type() or Gio.AppInfo.remove_supports_type().

New in version 2.20.

add_supports_type(content_type)[source]¶

Parameters:: content_type (str) – a string.
Raises:: GLib.Error
Returns:: True on success, False on error.
Return type:: bool

Adds a content type to the application information to indicate the application is capable of opening files with the given content type.

Return type:: bool

Checks if a supported content type can be removed from an application.

delete()[source]¶

Returns:: True if self has been deleted
Return type:: bool

Tries to delete a Gio.AppInfo.

On some platforms, there may be a difference between user-defined Gio.AppInfos which can be deleted, and system-wide ones which cannot. See Gio.AppInfo.can_delete().

New in version 2.20.

dup()[source]¶

Returns:: a duplicate of self.
Return type:: Gio.AppInfo

Creates a duplicate of a Gio.AppInfo.

equal(appinfo2)[source]¶

Parameters:: appinfo2 (Gio.AppInfo) – the second Gio.AppInfo.
Returns:: True if self is equal to appinfo2. False otherwise.
Return type:: bool

Checks if two Gio.AppInfos are equal.

Note that the check *may not* compare each individual field, and only does an identity check. In case detecting changes in the contents is needed, program code must additionally compare relevant fields.

get_commandline()[source]¶

Returns:: a string containing the self's commandline, or None if this information is not available
Return type:: str or None

Gets the commandline with which the application will be started.

New in version 2.20.

get_description()[source]¶

Returns:: a string containing a description of the application self, or None if none.
Return type:: str or None

Gets a human-readable description of an installed application.

get_display_name()[source]¶

Returns:: the display name of the application for self, or the name if no display name is available.
Return type:: str

Gets the display name of the application. The display name is often more descriptive to the user than the name itself.

New in version 2.24.

get_executable()[source]¶

Returns:: a string containing the self's application binaries name
Return type:: str

Gets the executable’s name for the installed application.

This is intended to be used for debugging or labelling what program is going to be run. To launch the executable, use Gio.AppInfo.launch() and related functions, rather than spawning the return value from this function.

get_icon()[source]¶

Returns:: the default Gio.Icon for self or None if there is no default icon.
Return type:: Gio.Icon or None

Gets the icon for the application.

get_id()[source]¶

Returns:: a string containing the application’s ID.
Return type:: str or None

Gets the ID of an application. An id is a string that identifies the application. The exact format of the id is platform dependent. For instance, on Unix this is the desktop file id from the xdg menu specification.

Note that the returned ID may be None, depending on how the self has been constructed.

get_name()[source]¶

Returns:: the name of the application for self.
Return type:: str

Gets the installed name of the application.

get_supported_types()[source]¶

Returns:: a list of content types.
Return type:: [str]

Retrieves the list of content types that app_info claims to support. If this information is not provided by the environment, this function will return None. This function does not take in consideration associations added with Gio.AppInfo.add_supports_type(), but only those exported directly by the application.

New in version 2.34.

launch(files, context)[source]¶

Parameters:

files ([Gio.File] or None) – a GLib.List of Gio.File objects
context (Gio.AppLaunchContext or None) – a Gio.AppLaunchContext or None

Raises:

GLib.Error

Returns:

True on successful launch, False otherwise.

Return type:

bool

Launches the application. Passes files to the launched application as arguments, using the optional context to get information about the details of the launcher (like what screen it is on). On error, error will be set accordingly.

To launch the application without arguments pass a None files list.

Note that even if the launch is successful the application launched can fail to start if it runs into problems during startup. There is no way to detect this.

Some URIs can be changed when passed through a Gio.File (for instance unsupported URIs with strange formats like mailto:), so if you have a textual URI you want to pass in as argument, consider using Gio.AppInfo.launch_uris() instead.

The launched application inherits the environment of the launching process, but it can be modified with Gio.AppLaunchContext.setenv() and Gio.AppLaunchContext.unsetenv().

On UNIX, this function sets the GIO_LAUNCHED_DESKTOP_FILE environment variable with the path of the launched desktop file and GIO_LAUNCHED_DESKTOP_FILE_PID to the process id of the launched process. This can be used to ignore GIO_LAUNCHED_DESKTOP_FILE, should it be inherited by further processes. The DISPLAY, XDG_ACTIVATION_TOKEN and DESKTOP_STARTUP_ID environment variables are also set, based on information provided in context.

launch_uris(uris, context)[source]¶

Parameters:

uris ([str] or None) – a GLib.List containing URIs to launch.
context (Gio.AppLaunchContext or None) – a Gio.AppLaunchContext or None

Raises:

GLib.Error

Returns:

True on successful launch, False otherwise.

Return type:

bool

Launches the application. This passes the uris to the launched application as arguments, using the optional context to get information about the details of the launcher (like what screen it is on). On error, error will be set accordingly. If the application only supports one URI per invocation as part of their command-line, multiple instances of the application will be spawned.

To launch the application without arguments pass a None uris list.

Note that even if the launch is successful the application launched can fail to start if it runs into problems during startup. There is no way to detect this.

launch_uris_async(uris, context, cancellable, callback, *user_data)[source]¶

Parameters:

uris ([str] or None) – a GLib.List containing URIs to launch.
context (Gio.AppLaunchContext or None) – a Gio.AppLaunchContext or None
cancellable (Gio.Cancellable or None) – a Gio.Cancellable
callback (Gio.AsyncReadyCallback or None) – a Gio.AsyncReadyCallback to call when the request is done
user_data (object or None) – data to pass to callback

Async version of Gio.AppInfo.launch_uris().

The callback is invoked immediately after the application launch, but it waits for activation in case of D-Bus–activated applications and also provides extended error information for sandboxed applications, see notes for Gio.AppInfo.launch_default_for_uri_async().

New in version 2.60.

launch_uris_finish(result)[source]¶

Parameters:: result (Gio.AsyncResult) – a Gio.AsyncResult
Raises:: GLib.Error
Returns:: True on successful launch, False otherwise.

New in version 2.34.

do_launch(files, context) virtual¶

Parameters:

files ([Gio.File] or None) – a GLib.List of Gio.File objects
context (Gio.AppLaunchContext or None) – a Gio.AppLaunchContext or None

Returns:

True on successful launch, False otherwise.

Return type:

bool

Launches the application. Passes files to the launched application as arguments, using the optional context to get information about the details of the launcher (like what screen it is on). On error, error will be set accordingly.

To launch the application without arguments pass a None files list.

Note that even if the launch is successful the application launched can fail to start if it runs into problems during startup. There is no way to detect this.

Some URIs can be changed when passed through a Gio.File (for instance unsupported URIs with strange formats like mailto:), so if you have a textual URI you want to pass in as argument, consider using Gio.AppInfo.launch_uris() instead.

The launched application inherits the environment of the launching process, but it can be modified with Gio.AppLaunchContext.setenv() and Gio.AppLaunchContext.unsetenv().

On UNIX, this function sets the GIO_LAUNCHED_DESKTOP_FILE environment variable with the path of the launched desktop file and GIO_LAUNCHED_DESKTOP_FILE_PID to the process id of the launched process. This can be used to ignore GIO_LAUNCHED_DESKTOP_FILE, should it be inherited by further processes. The DISPLAY, XDG_ACTIVATION_TOKEN and DESKTOP_STARTUP_ID environment variables are also set, based on information provided in context.

do_launch_uris(uris, context) virtual¶

On error, error will be set accordingly. If the application only supports one URI per invocation as part of their command-line, multiple instances of the application will be spawned.

To launch the application without arguments pass a None uris list.

Note that even if the launch is successful the application launched can fail to start if it runs into problems during startup. There is no way to detect this.
