addEventListener click Problem

[omara83529385]

I test Mouse Events and its work Perfectly (Left, Right, Middle KEYS) at Extend Script

But when run it on Aftereffects 2018 the left-key in mouse doesn't do anything

var w = new Window("palette"); 
var b = w.add ("button", [0,0,150,50], "test");


    w.center();
    w.show();  
    
    

    b.addEventListener ('click', function(K){
        var keys = [];
        if (K.ctrlKey) {
            keys[0] = "CTRL";
            }
        if (K.shiftKey) {
            keys[1] = "SHIFT";
            }
        if (K.altKey) {
            keys[2] = "ALT";
            }
        alert(K.button + "\n" + keys.toString() + "\n" + K.clientX + "    |   " + K.clientY);
        }
    )

I fix the problem in this way :

    var ctrl = false;
    var shift = false;
    var alt = false;


    b1.onClick = function() {  
        
         if(ctrl){
             alert("CTRL");
             }
         if(shift){
             alert("SHIFT");
             }
         if(alt){
             alert("ALT");
             }
         if(!ctrl && !shift && !alt) {
             alert("NO KEY");
             }

         ctrl = false;
         shift = false;
         alt = false;
    }
    
    b1.addEventListener ('mousedown', function(K){
    
        if (K.ctrlKey) {
            ctrl = true;
            }
        if (K.shiftKey) {
            shift = true;
            }
        if (K.altKey) {
            alt = true;
            }
    })

If anybody has a better solution please put it here

Wow, thx so much for the solution.

I have the same problem, tried erverything I can but still didn't find a good solution until now.

Before this, if I want to do the alt-click/shift-click stuff, I have to replace my buttons with images. But doing so, I have to do the highlighting manually while my mouse is on the image.  This is very fraustrating to work with. Your solution is great!

And can @Adobe fix this nasty bug so everybody can develope scripts better?

There's a perfectly logical way to catch modifier keys by checking ScriptUI.environment.keyboardState: http://estk.aenhancers.com/4%20-%20User-Interface%20Tools/event-handling.html?highlight=keyboardstat...

Here's the gist of it:

button.onClick = function() {
	var keyboardState = ScriptUI.environment.keyboardState;
	if (keyboardState.shift) {
		alert('shift');
	}

	// etc
};
