ScriptUI window.minimized = true; on Mac

Question

I would like to make custom palettes for Illustrator which have the ability to get out of the way, similar to native palettes.  On Windows, my minimized = true; command works, and the palette shrinks into a tiny bar, which I like.  However, same command on Mac does not do the trick.
#target illustrator
#targetengine main
function myPanel(){
    var arr = ["A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"];
    function paletteWindow(){
        var w = new Window('palette', 'My Panel', undefined, {resizeable: true});
        var g1 = w.add('group');
        var t = g1.add('treeview', undefined, []);   t.size = [200, 450];
        for(var i=0; i<arr.length; i++){
            var item = arr[i];
            var n = t.add('node', item);
        t.onDoubleClick = function(){
            if(t.selection != null && t.selection.text != ''){
                alert(t.selection.text);
        var btn_min = w.add('button', undefined, 'Minimize');
        btn_min.onClick = function(){
            w.minimized = true;
            w.update();
        w.onResizing = w.onResize = function () {this.layout.resize ();}
        w.onShow = function(){
            w.minimumSize.width = 220;
            w.minimumSize.height = 100;
            t.items[1].expanded = true;
        this.show = function(){w.show();}
    var thisPaletteWindow = new paletteWindow(); // have to call it like this, or it disappears.
    thisPaletteWindow.show();
myPanel();

Answer 1

Okay, I think I can live with the following workaround:
I can just have me a palette which has a button, the button shows the real palette and closes this one. The real palette has a button that closes that one and shows the tiny one!
Or, there can be a 'toolbar' which can show & hide other bigger palettes.
I made the following though, which uses window closing to get rid of non-visible windows. It is probably possible to do this by messing with the 'visible' property of the windows, and just keep one hidden. Well, with this setup, it's possible to pass in the configuration of the big palette as an object to be stored in the tiny window, and then to resurrect the element states of the big one when it's maximized, including the window's location so that it appears as if they are appearing back in the last place they were closed at. This could be re-purposed to pop up the big palette in the same location of the tiny one, so that they closer mimic the behavior of the native UI panels. This works for me in CC2014, so I may have to use this on a few things.
#target illustrator
#targetengine main
//need main engine here explicitly
function myPanel(){
    var arr = [];
    for(var i=33; i<123; i++){
        arr.push(String.fromCharCode(i)+" ------------------ text line");
    function tinyWindow(storeObj){
        var w = new Window('palette', 'MiniPanel', undefined, {borderless: false}); w.spacing = 0; w.margins = [0,0,0,0];
        w.location = storeObj.tinyWindowLocation;
        var btn = w.add('button', undefined, 'Maximize');
        this.show = function(){w.show();}
        btn.onClick = function(){
            storeObj.tinyWindowLocation = w.bounds;
            var thisPaletteWindow = new paletteWindow(storeObj);
            thisPaletteWindow.show();
            w.close();
    function paletteWindow(setupObj){
        var w = new Window('palette', 'My Panel');
        w.location = setupObj.bigWindowLocation;
        var g1 = w.add('group');
        var t = g1.add('treeview', undefined, []);  t.size = [200, 450];
        for(var i=0; i<arr.length; i++){
            var item = arr[i];
            var n = t.add('node', item);
        var e = w.add('edittext', undefined, setupObj.edittextContents, {readonly: true}); e.characters = 19;
        t.onDoubleClick = function(){
            if(t.selection != null && t.selection.text != ''){
                e.text = (t.selection.text);
        var btn_min = w.add('button', undefined, 'Minimize');
        btn_min.onClick = function(){
            var thisTinyWindow = new tinyWindow({edittextContents: e.text, tinyWindowLocation: setupObj.tinyWindowLocation, bigWindowLocation: w.location});
            thisTinyWindow.show();
            w.close();
        this.show = function(){w.show();}
    var thisTinyWindow = new tinyWindow({edittextContents: '', tinyWindowLocation: [920,514], bigWindowLocation: [860, 350]});
    thisTinyWindow.show();
myPanel();
