Since glibmm 2.34:

Returns
  A list of content types.

## ◆ get_type()

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

| inline

Provides access to the underlying C GObject.

## ◆ gobj() [2/2]

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

Provides access to the underlying C GObject.

## ◆ launch() [1/4]

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

  file | A File object.
  context | An AppLaunchContext.

Returns
  `true` on successful launch, `false` otherwise.

Since glibmm 2.30:

## ◆ launch() [2/4]

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

  file | A File object.

Returns
  `true` on successful launch, `false` otherwise.

Since glibmm 2.30:

## ◆ launch() [3/4]

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

  files | A List of File objects.
  context | A AppLaunchContext or `nullptr`.

Returns
  `true` on successful launch, `false` otherwise.

Exceptions

  Glib::Error |

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.

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.

Parameters

  uris | A URIs to launch.
  context | An AppLaunchContext.

Returns
  `true` on successful launch, `false` otherwise.

Since glibmm 2.30:

## ◆ launch_uri() [2/2]

bool Gio::AppInfo::launch_uri | ( | const std::string & | uris | ) |

A launch_uri() convenience overload.

Since glibmm 2.30:

## ◆ launch_uris() [1/3]

bool Gio::AppInfo::launch_uris | ( | const Glib::ListHandle< std::string >& | uris,
|  | GAppLaunchContext * | 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.

Deprecated:
  Use the method that takes an AppLaunchContext

Parameters

  uris | A List containing URIs to launch.
  context | A AppLaunchContext or `nullptr`.

Returns
  `true` on successful launch, `false` otherwise.

Exceptions

  Glib::Error |

## ◆ launch_uris() [2/3]

bool Gio::AppInfo::launch_uris | ( | const Glib::ListHandle< 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.

Parameters

  uris | A List containing URIs to launch.
  context | A AppLaunchContext or `nullptr`.

Returns
  `true` on successful launch, `false` otherwise.

| noexcept

## ◆ remove_supports_type()

bool Gio::AppInfo::remove_supports_type | ( | const std::string & | content_type | ) |

Removes a supported type from an application, if possible.

Parameters

  content_type | A string.

Returns
  `true` on success, `false` on error.

Exceptions

  Glib::Error |

## ◆ reset_type_associations()

static void Gio::AppInfo::reset_type_associations | ( | const std::string & | content_type | ) |
| static

Removes all changes to the type associations done by g_app_info_set_as_default_for_type(), g_app_info_set_as_default_for_extension(), g_app_info_add_supports_type() or g_app_info_remove_supports_type().

Since glibmm 2.20:

Parameters

  content_type | A content type.

## ◆ set_as_default_for_extension()

bool Gio::AppInfo::set_as_default_for_extension | ( | const std::string & | extension | ) |

Sets the application as the default handler for the given file extension.

Parameters

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

Returns
  `true` on success, `false` on error.

Exceptions

  Glib::Error |

## ◆ set_as_default_for_type()

bool Gio::AppInfo::set_as_default_for_type | ( | const std::string & | content_type | ) |

Sets the application as the default handler for a given type.

Parameters

  content_type | The content type.

Returns
  `true` on success, `false` on error.

Exceptions

  Glib::Error |

## ◆ set_as_last_used_for_type()

bool Gio::AppInfo::set_as_last_used_for_type | ( | const std::string & | content_type | ) |

Sets the application as the last used application for a given type.

This will make the application appear as first in the list returned by g_app_info_get_recommended_for_type(), regardless of the default application for that content type.

Parameters

  content_type | The content type.

Returns
  `true` on success, `false` on error.

Exceptions

  Glib::Error |

## ◆ should_show()

bool Gio::AppInfo::should_show | ( |  | ) | const

Checks if the application info should be shown in menus that list available applications.

Returns
  `true` if the appinfo should be shown, `false` otherwise.

## ◆ supports_files()

bool Gio::AppInfo::supports_files | ( |  | ) | const

Checks if the application accepts files as arguments.

Returns
  `true` if the appinfo supports files.

## ◆ supports_uris()

bool Gio::AppInfo::supports_uris | ( |  | ) | const

Checks if the application supports reading files and directories from URIs.

Returns
  `true` if the appinfo supports URIs.
