经过多次尝试，我设法创建一个工作的自定义进度条，即使用OnDraw命令定制它，它也会 Flink （我仍然不明白为什么，也许是用update命令连续重绘）。
我想添加一个按钮，将停止进度条（然后也脚本），也许添加一个警告消息，但我遇到了一个问题。
无论是在进度条前进时还是在正常的调色板上，按钮似乎对单击都没有响应。
在对话框中它可以工作，在调色板和窗口中它不能。
我怀疑这是因为，在photoshop中要保持调色板处于打开状态，它必须处于忙状态，否则它就会关闭，这导致我无法按下按钮。
我试了所有能想到的方法，但都没用。
有办法实现这个吗？
下面是我的代码示例：

progressbar (100);
    for ( var e = 0; e < 100; e++ ) {
        progressbar.progress ();
        }
    progressbar.close ();

    function progressbar (total) {
        var win = new Window ("palette", undefined, undefined, {closeButton: false, borderless: true});
        win.orientation = "row";
        var barheight = 15;
        var halfbarheight = barheight / 2;
        var barwidth = 500;
        var bar = win.add ("progressbar", [0, 0, barwidth, barheight], 0, total);
        bar.onDraw = function () {
            with (bar) {
                graphics.drawOSControl ();
                graphics.newPath ();
                graphics.moveTo (halfbarheight, 0);
                for (var a = 0; a < Math.PI; a += Math.PI / 100) {
                    graphics.lineTo ((-halfbarheight * Math.sin (a)) + halfbarheight, (-halfbarheight * Math.cos (a)) + halfbarheight);
                    }
                graphics.lineTo (halfbarheight + (bar.value * ((barwidth - barheight) / total)), barheight);
                for (var b = 0; b < Math.PI; b += Math.PI / 100) {
                    graphics.lineTo ((halfbarheight * Math.sin (b)) + halfbarheight + (bar.value * ((barwidth - barheight) / total)), (halfbarheight * Math.cos (b)) + halfbarheight);
                    }
                graphics.lineTo (halfbarheight, 0);
                graphics.closePath ();
                graphics.fillPath (graphics.newBrush (graphics.BrushType.SOLID_COLOR, [0.25, 0.83, 0.1]));
                }
            }
        var close = win.add ("iconbutton", [0, 0, 15, 15]);
        close.onDraw = function (event) {
            with (close) {
                graphics.drawOSControl ();
                graphics.ellipsePath (0, 0, size[0], size[1]);
                graphics.fillPath (graphics.newBrush (graphics.BrushType.SOLID_COLOR, [0.6, 0, 0]));
                if (event.mouseOver) {
                    graphics.fillPath (graphics.newBrush (graphics.BrushType.SOLID_COLOR, [0.85, 0, 0]));
                    }
                }
            }
        close.onClick = function () {
            progressbar.close ();
            return;
            }
        progressbar.close = function () {
            win.close ();
            }
        progressbar.progress = function () {
            bar.value++;
            $.sleep (100);
            win.update ();
            }
        win.show ();
        }
