◆ get_display()

std::string Gio::AppLaunchContext::get_display	(	const Glib::RefPtr< AppInfo > &	info,
		const std::vector< Glib::RefPtr< Gio::File > > &	files
	)

Gets the display string for the context.

This is used to ensure new applications are started on the same display as the launching application, by setting the DISPLAY environment variable.

Parameters

info	A AppInfo.
files	A List of File objects.

Returns: A display string for the display.

◆ get_environment()

std::vector< Glib::ustring > Gio::AppLaunchContext::get_environment ( ) const

Gets the complete environment variable list to be passed to the child process when context is used to launch an application.

This is a nullptr-terminated array of strings, where each string has the form KEY=VALUE.

Since glibmm 2.32:

Returns: The child's environment.

◆ get_startup_notify_id()

std::string Gio::AppLaunchContext::get_startup_notify_id	(	const Glib::RefPtr< AppInfo > &	info,
		const std::vector< Glib::RefPtr< Gio::File > > &	files
	)

Initiates startup notification for the application and returns the DESKTOP_STARTUP_ID for the launched operation, if supported.

Startup notification IDs are defined in the FreeDesktop.Org Startup Notifications standard.

Parameters

info	A AppInfo.
files	A List of of File objects.

Returns: A startup notification ID for the application, or nullptr if not supported.

◆ get_type()

static GType Gio::AppLaunchContext::get_type ( )

static

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

◆ gobj() [1/2]

GAppLaunchContext * Gio::AppLaunchContext::gobj ( )

inline

Provides access to the underlying C GObject.

◆ gobj() [2/2]

const GAppLaunchContext * Gio::AppLaunchContext::gobj ( ) const

inline

Provides access to the underlying C GObject.

◆ gobj_copy()

GAppLaunchContext * Gio::AppLaunchContext::gobj_copy ( )

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

◆ launch_failed()

void Gio::AppLaunchContext::launch_failed ( const std::string & startup_notify_id )

Called when an application has failed to launch, so that it can cancel the application startup notification started in g_app_launch_context_get_startup_notify_id().

Parameters

startup_notify_id The startup notification id that was returned by g_app_launch_context_get_startup_notify_id().

◆ operator=()

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

noexcept

◆ setenv()

void Gio::AppLaunchContext::setenv	(	const Glib::ustring &	variable,
		const Glib::ustring &	value
	)

Arranges for variable to be set to value in the child's environment when context is used to launch an application.

Since glibmm 2.32:

Parameters

variable	The environment variable to set.
value	The value for to set the variable to.

◆ unsetenv()

void Gio::AppLaunchContext::unsetenv ( const Glib::ustring & variable )

Arranges for variable to be unset in the child's environment when context is used to launch an application.

Since glibmm 2.32:

Parameters

variable The environment variable to remove.

◆ wrap()

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

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.
