Detailed Description

Member Function Documentation

◆ create()

static Glib::RefPtr< DesktopAppInfo > Gio::DesktopAppInfo::create ( const std::string & desktop_id )

static

Creates a new Gio::DesktopAppInfo 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).

Parameters

desktop_id The desktop file ID.

Returns: A new Gio::DesktopAppInfo, or nullptr if no desktop file with that ID exists.

◆ create_from_filename()

static Glib::RefPtr< DesktopAppInfo > Gio::DesktopAppInfo::create_from_filename ( const std::string & filename )

static

Creates a new Gio::DesktopAppInfo.

Parameters

filename The path of a desktop file, in the GLib filename encoding.

Returns: A new Gio::DesktopAppInfo or nullptr on error.

◆ create_from_keyfile()

static Glib::RefPtr< DesktopAppInfo > Gio::DesktopAppInfo::create_from_keyfile ( const Glib::RefPtr< Glib::KeyFile > & key_file )

static

Creates a new Gio::DesktopAppInfo.

Since glibmm 2.18:

Parameters

key_file An opened Glib::KeyFile.

Returns: A new Gio::DesktopAppInfo or nullptr on error.

◆ get_action_name()

Glib::ustring Gio::DesktopAppInfo::get_action_name ( const Glib::ustring & action_name ) const

Gets the user-visible display name of the ‘additional application actions’ specified by action_name.

This corresponds to the Name key within the keyfile group for the action.

Since glibmm 2.38:

Parameters

action_name The name of the action as from Gio::DesktopAppInfo::list_actions().

Returns: The locale-specific action name.

◆ get_boolean()

bool Gio::DesktopAppInfo::get_boolean ( const Glib::ustring & key ) const

Looks up a boolean value in the keyfile backing info.

The key is looked up in the Desktop Entry group.

Since glibmm 2.36:

Parameters

key	The key to look up.

Returns: The boolean value, or false if the key is not found.

◆ get_categories()

std::string Gio::DesktopAppInfo::get_categories ( ) const

Gets the categories from the desktop file.

Returns: The unparsed Categories key from the desktop file; i.e. no attempt is made to split it by ; or validate it.

◆ get_filename()

std::string Gio::DesktopAppInfo::get_filename ( ) const

When info was created from a known filename, return it.

In some situations such as a Gio::DesktopAppInfo returned from Gio::DesktopAppInfo::new_from_keyfile(), this function will return nullptr.

Since glibmm 2.24:

Returns: The full path to the file for info, or nullptr if not known.

◆ get_generic_name()

std::string Gio::DesktopAppInfo::get_generic_name ( ) const

Gets the generic name from the desktop file.

Returns: The value of the Generic::Name key.

◆ get_keywords()

std::vector< Glib::ustring > Gio::DesktopAppInfo::get_keywords ( ) const

Gets the keywords from the desktop file.

Since glibmm 2.32:

Returns: The value of the Keywords key.

◆ get_locale_string()

Glib::ustring Gio::DesktopAppInfo::get_locale_string ( const Glib::ustring & key )

Looks up a localized string value in the keyfile backing info translated to the current locale.

The key is looked up in the Desktop Entry group.

Since glibmm 2.56:

Parameters

key	The key to look up.

Returns: A newly allocated string, or nullptr if the key is not found.

◆ get_nodisplay()

bool Gio::DesktopAppInfo::get_nodisplay ( ) const

Gets the value of the No::Display key which helps determine if the application info should be shown in menus.

See G_KEY_FILE_DESKTOP_KEY_NO_DISPLAY and Gio::AppInfo::should_show().

Since glibmm 2.30:

Returns: The value of the No::Display key.

◆ get_show_in()

bool Gio::DesktopAppInfo::get_show_in ( const std::string & desktop_env ) const

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.

desktop_env should typically be given as nullptr, in which case the XDG_CURRENT_DESKTOP environment variable is consulted. If you want to override the default mechanism then you may specify desktop_env, but this is not recommended.

Note that Gio::AppInfo::should_show() for info will include this check (with nullptr for desktop_env) as well as additional checks.

Since glibmm 2.30:

Parameters

desktop_env 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.

◆ get_startup_wm_class()

std::string Gio::DesktopAppInfo::get_startup_wm_class ( ) const

Retrieves the StartupWMClass field from info.

This represents the WM_CLASS property of the main window of the application, if launched through info.

Since glibmm 2.34:

Returns: The startup WM class, or nullptr if none is set in the desktop file.

◆ get_string()

Glib::ustring Gio::DesktopAppInfo::get_string ( const Glib::ustring & key )

Looks up a string value in the keyfile backing info.

The key is looked up in the Desktop Entry group.

Since glibmm 2.36:

Parameters

key	The key to look up.

Returns: A newly allocated string, or nullptr if the key is not found.

◆ get_type()

static GType Gio::DesktopAppInfo::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

◆ gobj() [1/2]

GDesktopAppInfo * Gio::DesktopAppInfo::gobj ( )

inline

Provides access to the underlying C GObject.

◆ gobj() [2/2]

const GDesktopAppInfo * Gio::DesktopAppInfo::gobj ( ) const

inline

Provides access to the underlying C GObject.

◆ gobj_copy()

GDesktopAppInfo * Gio::DesktopAppInfo::gobj_copy ( )

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

◆ has_key()

bool Gio::DesktopAppInfo::has_key ( const Glib::ustring & key ) const

Returns whether key exists in the Desktop Entry group of the keyfile backing info.

Since glibmm 2.36:

Parameters

key	The key to look up.

Returns: true if the key exists.

◆ is_hidden()

bool Gio::DesktopAppInfo::is_hidden ( ) const

A desktop file is hidden if the Hidden key in it is set to True.

Returns: true if hidden, false otherwise.

◆ launch_action() [1/2]

void Gio::DesktopAppInfo::launch_action ( const Glib::ustring & action_name )

A launch_action() convenience overload.

◆ launch_action() [2/2]

void Gio::DesktopAppInfo::launch_action	(	const Glib::ustring &	action_name,
		const Glib::RefPtr< AppLaunchContext > &	launch_context
	)

Activates the named application action.

You may only call this function on action names that were returned from Gio::DesktopAppInfo::list_actions().

Note that if the main entry of the desktop file indicates that the application supports startup notification, and launch_context is non-nullptr, then startup notification will be used when activating the action (and as such, invocation of the action on the receiving side must signal the end of startup notification when it is completed). This is the expected behaviour of applications declaring additional actions, as per the desktop file specification.

As with Gio::AppInfo::launch() there is no way to detect failures that occur while using this function.

Since glibmm 2.38:

Parameters

action_name	The name of the action as from Gio::DesktopAppInfo::list_actions().
launch_context	A Gio::AppLaunchContext.

◆ list_actions()

std::vector< Glib::ustring > Gio::DesktopAppInfo::list_actions ( ) const

Returns the list of ‘additional application actions’ supported on the desktop file, as per the desktop file specification.

As per the specification, this is the list of actions that are explicitly listed in the Actions key of the Desktop Entry group.

Since glibmm 2.38:

Returns: A list of strings, always non-nullptr.

◆ operator=()

DesktopAppInfo & Gio::DesktopAppInfo::operator= ( DesktopAppInfo && src )

noexcept

Friends And Related Symbol Documentation

◆ wrap()

Glib::RefPtr< Gio::DesktopAppInfo > wrap	(	GDesktopAppInfo *	object,
		bool	take_copy = `false`
	)

A Glib::wrap() method for this object.

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns: A C++ instance that wraps this C instance.
