static GType Gio::AppInfo::get_type ( )
static

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

GAppInfo* Gio::AppInfo::gobj ( )
inline

Provides access to the underlying C GObject.

const GAppInfo* Gio::AppInfo::gobj ( ) const
inline

Provides access to the underlying C GObject.

bool Gio::AppInfo::launch ( const Glib::RefPtr< Gio::File >&  file,
const Glib::RefPtr< AppLaunchContext >&  context 
)

Launches the application.

This passes the file to the launched application as an argument, using the optional context to get information about the details of the launcher (like what screen it is on). On error, an exception will be thrown accordingly.

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 GFile (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 launch_uris() instead.

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 and DESKTOP_STARTUP_ID environment variables are also set, based on information provided in context.

Parameters
fileA File object.
contextAn AppLaunchContext.
Returns
true on successful launch, false otherwise.
Since glibmm 2.30:
bool Gio::AppInfo::launch ( const Glib::RefPtr< Gio::File >&  file)

Launches the application.

This passes the file to the launched application as an argument. On error, an exception will be thrown accordingly.

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 GFile (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 launch_uris() instead.

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 and DESKTOP_STARTUP_ID environment variables are also set, based on information provided in context.

Parameters
fileA File object.
Returns
true on successful launch, false otherwise.
Since glibmm 2.30:
bool Gio::AppInfo::launch ( const std::vector< Glib::RefPtr< Gio::File > >&  files,
const Glib::RefPtr< AppLaunchContext >&  context 
)

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 nullptr 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 GFile (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 g_app_info_launch_uris() instead.

The launched application inherits the environment of the launching process, but it can be modified with g_app_launch_context_setenv() and g_app_launch_context_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 and DESKTOP_STARTUP_ID environment variables are also set, based on information provided in context.

Parameters
filesA List of File objects.
contextA AppLaunchContext or nullptr.
Returns
true on successful launch, false otherwise.
Exceptions
Glib::Error
bool Gio::AppInfo::launch ( const std::vector< Glib::RefPtr< Gio::File > >&  files)

static bool Gio::AppInfo::launch_default_for_uri ( const std::string uri,
const Glib::RefPtr< AppLaunchContext >&  context 
)
static

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 g_app_info_launch_default_for_uri_async() instead.

Parameters
uriThe uri to show.
contextAn optional AppLaunchContext.
Returns
true on success, false on error.
Exceptions
Glib::Error
static bool Gio::AppInfo::launch_default_for_uri ( const std::string uri)
static

A launch_default_for_uri() convenience overload.

static void Gio::AppInfo::launch_default_for_uri_async ( const std::string uri,

const SlotAsyncReady &  slot,
const Glib::RefPtr< Cancellable >&  cancellable 
)
static

Async version of g_app_info_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.

Since glibmm 2.50:
Parameters
uriThe uri to show.
contextAn optional AppLaunchContext.
cancellableA Cancellable.
slotA SlotAsyncReady to call when the request is done.

Glib::Error
bool Gio::AppInfo::launch_uri ( const std::string uri,
const Glib::RefPtr< AppLaunchContext >&  context 
)

Launches the application.

This passes the uri to the launched application as an arguments, using the optional context to get information about the details of the launcher (like what screen it is on). On error, an exception will be thrown accordingly.

Since glibmm 2.30:
bool Gio::AppInfo::launch_uris ( const std::vector< std::string > &  uris,
const Glib::RefPtr< AppLaunchContext >&  context 
)

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.

To launch the application without arguments pass a nullptr 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.
