Sending Raw AppleEvents

Sending Raw AppleEvents is a two step process:

Step 1 - Identify the target application

This is done using the MacOS.appSelf() or MacOS.appBySignature() methods. MacOS.appSelf() targets the currently running application while MacOS.appBySignature() targets any other running application on your Macintosh.

For instance, to target the MacOS Finder:

Sample

var target = MacOS.appBySignature("MACS");

Step 2 - Construct and send the AppleEvent

Once you have created a target for the AppleEvent, you can use the following syntax to send an AppleEvent:

Sample

var result = target.sendAE(suiteID, eventID, parameters);

Putting these two steps together, the following script tells the Finder to display a dialog box containing a message:

Sample

var target = MacOS.appBySignature("MACS");
var result = target.sendAE("syso", "dlog",
{"ae_----":"Hello World", "AE_btns":["OK"], "AE_dflt":1, "AE_disp":1});
