UiBinder小部件中的自定义属性 [英] Custom attributes in UiBinder widgets

问题描述

我为我的应用使用了GWT和UiBinder，并且我正在尝试这样做。

< g：TextBox ui：


但是自定义<$ c $ c> placeholder 属性不起作用，因为 TextBox setPlaceholder 方法c> - 我需要这个：
$ b

searchBox.getElement（）。setAttribute（placeholder，search）;

返回到java代码中。关于如何在UiBinder本身做到这一点的想法？我想我可以将它改为正常的输入元素，并尝试获取参考及其价值，但我宁愿不走那条路。 如何创建自定义 SearchBox > TextBox with method setPlaceholder（String placeholder）？

然后在UiBinder中：

< custom：SearchBox ui：field =searchBoxstyleName ={style.searchBox}
placeholder =search/>

I'm using GWT and UiBinder for my app, and I'm trying to do this

<g:TextBox ui:field="searchBox" styleName="{style.searchBox}" placeholder="search" />

But the custom placeholder attribute won't work because there isn't a setPlaceholder method on TextBox - I need to this:

searchBox.getElement().setAttribute("placeholder", "search");

back in the java code. Any ideas on how to do this in UiBinder itself? I suppose I could change it over to a normal input element and try to grab a reference and its value, but I'd rather not go down that road.

解决方案

What about creating custom SearchBox that extends TextBox with method setPlaceholder(String placeholder) ?

Then in UiBinder:

<custom:SearchBox ui:field="searchBox" styleName="{style.searchBox}" placeholder="search" />
