Interface ApplicationCreationOptions

The options object required by Application.start.

The following options are required:

  • uuid is required in the app manifest as well as by Application.start
  • name is optional in the app manifest but required by Application.start
  • url is optional in both the app manifest Application.start and but is usually given (defaults to "about:blank" when omitted).

IMPORTANT NOTE: This object inherits all the properties of the window creation options object, which will take priority over those of the same name that may be provided in mainWindowOptions.
