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

问题描述

我想在 javax.swing.JTextField 中添加一个提示值。它应该看起来像Firefox渲染< input type =texttitle =bla> 。这将在背景中创建一个带有文本bla的编辑字段。如果文本框具有焦点，则标题文本会消失，如果用户离开编辑框而没有文本，则会再次出现。

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）swing组件执行此类操作？

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

推荐答案

看一下这个： http://code.google.com/p/xswingx/

实施它并不是很困难顺便一提，顺便说一句。几个听众和自定义渲染器和瞧。

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