        <button label="Procesing" onClick="Clients.showBusy(null)"></button>

我想覆盖处理小部件,以便我可以实现这一点。 enter image description here

我已经搜索过,在ZK文档中但是没有找到任何帮助,有没有人尝试过这个或者任何提示,链接或引用,这可以在ZK中实现吗?

请尝试

<zk>
    <button label="busy">
        <attribute name="onClick">
            busyWin.doModal();
            Div div = busyWin.getFellow("div");
            Clients.showBusy(div, null);
        </attribute>
    </button>
    <window id="busyWin" visible="false" position="center"
        border="normal" title="busy..." xmlns:w="client">
        <attribute w:name="bind_">
            function (desktop, skipper, after) {
                this.$bind_(desktop, skipper, after);
                if (this._drag)
                    this._drag.opts.ignoredrag = true; // prevent dragging
            }
        </attribute>
        <hbox>
            <div id="div" height="30px" width="30px" style="color: transparent;">a</div>
            <button label="abort">
                <attribute name="onClick">
                    Clients.clearBusy(div);
                    busyWin.setMode("embedded");
                    busyWin.setVisible(false);
                </attribute>
