`G_APPLICATION_HANDLES_OPEN`

  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.

  - Value: `4`
  - Nickname: `handles-open`
  - Available since: 2.28
`G_APPLICATION_HANDLES_COMMAND_LINE`

  - Value: `8`
  - Nickname: `handles-command-line`
  - Available since: 2.28
`G_APPLICATION_SEND_ENVIRONMENT`

  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().

  - Value: `16`
  - Nickname: `send-environment`
  - Available since: 2.28
`G_APPLICATION_NON_UNIQUE`

  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.

  - Nickname: `non-unique`
  - Available since: 2.28
