## Constructor & Destructor Documentation

virtual Gio::AppInfo::~AppInfo | ( |  | ) | `[virtual]`

## Member Function Documentation

static void Gio::AppInfo::add_interface | ( | GType | gtype_implementer | ) | `[static]`

GAppInfo* Gio::AppInfo::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

Reimplemented in Gio::DesktopAppInfo.

const GAppInfo* Gio::AppInfo::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

Reimplemented in Gio::DesktopAppInfo.

static Glib::RefPtr<AppInfo> Gio::AppInfo::create_from_commandline | ( | const std::string & | commandline,
|  | const std::string & | application_name,
|  | AppInfoCreateFlags | flags |
| ) |  |  | `[static]`

bool Gio::AppInfo::equal | ( | const Glib::RefPtr<AppInfo>& | other | ) | const

Checks if two AppInfos are equal.

Parameters:

  | appinfo2 | The second AppInfo.

Returns:
  `true` if appinfo1 is equal to appinfo2. `false` otherwise.

std::string Gio::AppInfo::get_id | ( |  | ) | const

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 `0`, depending on how the appinfo has been constructed.

Returns:
  A string containing the application's ID.

std::string Gio::AppInfo::get_name | ( |  | ) | const

Gets the installed name of the application.

Returns:
  The name of the application for appinfo.

std::string Gio::AppInfo::get_description | ( |  | ) | const

Gets a human-readable description of an installed application.

Returns:
  A string containing a description of the application appinfo, or `0` if none.

std::string Gio::AppInfo::get_executable | ( |  | ) | const

Gets the executable's name for the installed application.

Returns:
  A string containing the appinfo's application binary's name.

Glib::RefPtr<Icon> Gio::AppInfo::get_icon | ( |  | ) |

Gets the icon for the application.

Returns:
  The default Icon for appinfo.

const Glib::RefPtr<const Icon> Gio::AppInfo::get_icon | ( |  | ) | const

Gets the icon for the application.

Returns:
  The default Icon for appinfo.

bool Gio::AppInfo::launch | ( | const Glib::ListHandle<std::string>& | files,
|  | const Glib::RefPtr<AppLaunchContext>& | launch_context |
| ) |  |  |

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 `0` 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.

Parameters:

  | files | A List of File objects.
  | launch_context | A AppLaunchContext.

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

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

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

Returns:
  `true` if the appinfo supports URIs.

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

Checks if the application accepts files as arguments.

Returns:
  `true` if the appinfo supports files.

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

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 `0` 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.
  | launch_context | A AppLaunchContext.

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

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.

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.

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

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

Parameters:

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

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

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

Adds a content type to the application information to indicate the application is capable of opening files with the given content type.

Parameters:

  | content_type | A string.

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

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

Checks if a supported content type can be removed from an application.

Returns:
  `true` if it is possible to remove supported content types from a given appinfo, `false` if not.

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.
