I am trying to code a gnome-shell extension. It uses Javascript. But one major problem when I want to use setTimeout() it tells me this in the log: ReferenceError: setTimeout is not defined, what I am going to reach here is I want to call a function in non-blocking way using setTimeout(). Maybe one of you has met this issue before or you may have a solution/alternative for me.

  • setTimeout is not part of ECMAScript so it is possible that a framework does not supply it. Try with window.setTimeout() (the difference: global and local timeout).

  • this._timeout = Mainloop.timeout_add_seconds(10, Lang.bind(this, this.{function})); works as a timeout to {function}.

  • It works, of course with const Mainloop = imports.mainloop; at the top. Thanks for the help.

Just to capture this in an answer:

const Mainloop = imports.mainloop;

...

Mainloop.timeout_add(1000, () => log('one second later!'));
