Object (const Glib::ConstructParams & construct_params) | |

~Object () noexcept override | |
![]() | |
ObjectBase () | |
This default constructor is called implicitly from the constructor of user-derived classes, even if, for instance, Gtk::Button calls a different ObjectBase constructor. | |
ObjectBase (const char * custom_type_name) | |
A derived constructor always overrides this choice. | |
ObjectBase (const std::type_info & custom_type_info) | |
This constructor is a special feature to allow creation of derived types on the fly, without having to use g_object_new() manually. | |

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.
info | The app info. |
files | A list of Gio::File objects. |
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
.
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 XDG_ACTIVATION_TOKEN
or DESKTOP_STARTUP_ID
for the launched operation, if supported.
The returned token may be referred to equivalently as an ‘activation token’ (using Wayland terminology) or a ‘startup sequence ID’ (using X11 terminology). The two are interoperable.
Activation tokens are defined in the XDG Activation Protocol, and startup notification IDs are defined in the freedesktop.org Startup Notification Protocol.
Support for the XDG Activation Protocol was added in GLib 2.76. Since GLib 2.82 info and files can be nullptr
. If that’s not supported by the backend, the returned token will be nullptr
.
info | The app info. |
files | A list of Gio::File objects. |
