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

OnClick 按钮我看到这个：
I want to Override the Processing widget so that I can acheive this. 
我在 ZK 文档中进行了搜索，但没有找到任何帮助，有没有人之前尝试过这个或任何提示、链接或参考，这可以在 ZK 中实现吗？
请尝试

<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>
