Known Implementation

gio.AppInfo is implemented by gio.DesktopAppInfo

Description

gio.AppInfo and gio.AppLaunchContext 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 gio.File.get_path()) when using gio.AppInfo.launch() even if the application requested an URI and not a POSIX path. For example for an 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 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 mailto:, 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 gio.File constructors (since gvfs implements the GVfs extension point). As such, if the application needs to examine the URI, it needs to use gio.File.get_uri() or similar on gio.File. In other words, an application cannot assume that the URI passed to e.g. gio.File() constructor is equal to the result of gio.File.get_uri().

Constructor

    gio.AppInfo(commandline, application_name=None, flags=gio.APP_INFO_CREATE_NONE)

commandline :

the commandline to use

application_name :

the application name, or None to use commandline.

flags :

flags that can specify details of the created, from Gio AppInfo Create Flags Constants

Returns :

a new gio.AppInfo for given command.

Creates a new gio.AppInfo from the given information.

Methods

gio.AppInfo.add_supports_type

    def add_supports_type(content_type)

content_type :

A string.

The add_supports_type() method adds a content type to the application information to indicate the application is capable of opening files with the given content type.

gio.AppInfo.can_delete

    def can_delete()

Returns :

True if appinfo can be deleted.

The can_delete() method obtains the information whether the gio.AppInfo can be deleted. See gio.AppInfo.delete().

gio.AppInfo.can_remove_supports_type

    def can_remove_supports_type()

Returns :

True if it is possible to remove supported content types from a given appinfo, False if not.

The can_remove_supports_type() method checks if a supported content type can be removed from an application.

gio.AppInfo.delete

    def delete()

Returns :

True if appinfo has been deleted.

The delete() method tries to delete an 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().

gio.AppInfo.dup

    def dup()

Returns :

A duplicate of appinfo.

The dup() method creates a duplicate of a gio.AppInfo.

gio.AppInfo.equal

    def equal(icon2)

appinfo2 :

the second gio.AppInfo

Returns :

True if appinfo1 is equal to appinfo2. False otherwise.

The equal() method checks if two gio.AppInfos are equal.

gio.AppInfo.get_commandline

    def get_commandline()

Returns :

a string containing the appinfo's commandline, or None if this information is not available.

The get_commandline() method gets the commandline with which the application will be started.

gio.AppInfo.get_description

    def get_description()

Returns :

A string containing a description of the application appinfo, or None if none.

The get_description() method gets a human-readable description of an installed application.

gio.AppInfo.get_executable

    def get_executable()

Returns :

a string containing the appinfo's application binary's name.

The get_description() method gets the executable's name for the installed application.

gio.AppInfo.get_icon

    def get_icon()

Returns :

the default gio.Icon for appinfo.

The get_icon() method gets the icon for the application.

gio.AppInfo.get_id

    def get_id()

Returns :

a string containing the application's ID.

The get_id() method 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 appinfo has been constructed.

gio.AppInfo.get_name

    def get_name()

Returns :

the name of the application for appinfo.

The get_name() method gets the installed name of the application.

gio.AppInfo.launch

    def launch(files, launch_context)

files :

a list of gio.File objects.

launch_context :

a gio.AppLaunchContext or None.

Returns :

True on successful launch, False otherwise.

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

To lauch the application without arguments pass a None for 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.File.launch_uris() instead.

gio.AppInfo.launch_uris

    def launch_uris(uris, launch_context)

uris :

a list containing URIs to launch.

launch_context :

a gio.AppLaunchContext or None.

Returns :

True on successful launch, False otherwise.

The launch_uris() method launches the application. Passes uris to the launched application as arguments, using the optional launch_context to get information about the details of the launcher (like what screen it is on). On error, error will be set accordingly.

To lauch the application without arguments pass a None for 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.

gio.AppInfo.remove_supports_type

    def remove_supports_type(content_type)

content_type :

A string.

The remove_supports_type() method removes a supported type from an application, if possible.

gio.AppInfo.set_as_default_for_extension

    def set_as_default_for_extension(extension)

extension :

A string containing the file extension (without the dot).

The set_as_default_for_extension() method sets the application as the default handler for the given file extention.

gio.AppInfo.set_as_default_for_type

    def set_as_default_for_type(content_type)

content_type :

The content type.

The set_as_default_for_type() method sets the application as the default handler for a given type.

gio.AppInfo.should_show

    def should_show()

Returns :

True if the appinfo should be shown, False otherwise.

The should_show() method checks if the application info should be shown in menus that list available applications.

gio.AppInfo.supports_files

    def supports_files()

Returns :

True if the appinfo supports files.

The supports_files() method checks if the application accepts files as arguments.

gio.AppInfo.supports_uris

    def supports_uris()

Returns :

True if the appinfo supports uris.

The supports_uris() method checks if the application accepts uris as arguments.

Functions

gio.app_info_get_all

    def app_info_get_all()

Returns :

A list of gio.AppInfos.

The app_info_get_all() function gets a list of all of the applications currently registered on this system.

For desktop files, this includes applications that have NoDisplay=true set or are excluded from display by means of OnlyShowIn or NotShowIn. See gio.AppInfo.should_show(). The returned list does not include applications which have the Hidden key set.

gio.app_info_get_all_for_type

    def app_info_get_all_for_type(content_type)

content_type :

the content type to find a gio.AppInfo for.

uri_scheme :

a string containing a URI scheme.

Returns :

gio.AppInfo for given uri_scheme or None on error.

The app_info_get_default_for_uri_scheme() function gets the default application for launching applications using this URI scheme. A URI scheme is the initial part of the URI, up to but not including the ':', e.g. "http", "ftp" or "sip".

gio.app_info_reset_type_association

    def app_info_reset_type_association(content_type)

content_type :

a content type

The app_info_reset_type_association() function removes all changes to the type associations done by set_as_default_for_type(), set_as_default_for_extension(), add_supports_type() or remove_supports_type().
