  Event listeners for dockable panels

  Posted by Chris Orcfilm on September 24, 2019 at 7:19 pm

  So, I have a dockable panel and I need to update a text field in it if the name of the project changes, such as from untitled to a saved filename or if opening a different project or opening a new project (untitled), I want the dockable panel to update the text field.

  Trouble is, I can’t seem to figure out how to trigger the change when these events occur.

  The closest I’ve got is trying to add an event listener but I can’t get it to work.
  For example, I’m trying to use:
  var saveEL = app.project.addEventListener('afterSave', function(theEvent) {
alert('saved'); //here is where I'll run the update code
});
  but that throws the error: “Function app.addEventListener is undefined”
  I’ve also tried just app.addEventListener but same error.

  Hoping I’m missing the obvious?

  I’m testing in AE 2018 currently.

  Thank you for reading!

  I think you need to add the event listener to your text field, not to the app. But I don’t know of a way to make it listen the save of the project.

  Thank Andrei, I think you may be thinking of object specific events like onFocus, onChange, etc. I’m referring to Application or Project events. Forgive me if I am misunderstanding but thanks for the thought!
