Does illustrator extendscript have an event listener?
I need a certain function to be activated when a object/group is selected.

I am planning to actually use this in cep extension, it will be some change in UI depending on number of selected objects. 

Correct answer Charu Rajput

Yes, you need to include the file in your code where all these events are defined.

Attach is the link to download the file.

Let me know if that works after including the file.

Hi,

Yes, you can use the AIHostAdapter to capture the selection event. The event you’re looking for is:

AIEvent.ART_SELECTION_CHANGED

For more information about AIHostAdapter, you can refer to the following link:

Best regards

    Hi @Charu Rajput 
    Thank you for this!

    I pasted AIHostAdapter.aip inside:
    .....\Plug-ins\Extensions
    and AIHostAdapter is now in AI System info

    and in js I tried this code:
    AIEventAdapter.getInstance().addEventListener(
    AIEvent.ART_SELECTION_CHANGED,
    function (eve) {
    alert(eve.type + " invoked.");
    }
    );

    But it does not work.
    Do I need something else here, on github there are  only AIHostAdapter.aip?
