Allow another instance to take over the bus name. Since: 2.60

Allow users to override the application ID from the command line with --gapplication-app-id. Since: 2.48

Default

This application handles command line arguments (in the primary instance). Note that this flag only affect the default implementation of local_command_line(). See g_application_run() for details.

This application handles opening files (in the primary instance). Note that this flag only affects the default implementation of local_command_line(), and has no effect if %G_APPLICATION_HANDLES_COMMAND_LINE is given. See g_application_run() for details.

Don't try to become the primary instance.

Run as a service. In this mode, registration fails if the service is already running, and the application will initially wait up to 10 seconds for an initial activation message to arrive.

Make no attempts to do any of the typical single-instance application negotiation, even if the application ID is given. The application neither attempts to become the owner of the application ID nor does it check if an existing owner already exists. Everything occurs in the local process. Since: 2.30.

Take over from another instance. This flag is usually set by passing --gapplication-replace on the commandline. Since: 2.60

Send the environment of the launching process to the primary instance. Set this flag if your application is expected to behave differently depending on certain environment variables. For instance, an editor might be expected to use the GIT_COMMITTER_NAME environment variable when editing a git commit message. The environment is available to the #GApplication::command-line signal handler, via g_application_command_line_getenv().
