带有输入提示的 Java JTextField [英] Java JTextField with input hint

问题描述

我想向我的 javax.swing.JTextField 添加一个提示值.它应该看起来像 的 Firefox 渲染.这会在背景中创建一个带有文本bla"的编辑字段.如果文本框有焦点，则标题文本会消失，如果用户离开没有文本的编辑框，则会重新出现.

I would like to add a hint value to my javax.swing.JTextField. It should look like Firefox rendering of <input type="text" title="bla">. This creates an edit field with the text 'bla' in the background. If the textbox has focus the title-text disappears and just reappears if the user leaves the editbox without text.

是否有(免费的)摆动组件可以执行此类操作?

Is there a (free) swing component that does something like this?

推荐答案

看看这个:http://code.google.com/p/xswingx/

顺便说一句，自己实现它并不是很难.几个侦听器和自定义渲染器，瞧.

It is not very difficult to implement it by yourself, btw. A couple of listeners and custom renderer and voila.
