如何在输入验证期间显示临时气球工具提示？ [英] How to display a temporary baloon tooltip during input validation?

问题描述

我有点习惯于GUI习惯用法，当我在文本输入字段中键入错误时，会从字段中弹出一个气球，其中包含有关我出错/预期输入的信息。在我再次输入之前它仍然可见。
但现在我找不到任何指向的例子。

I'm somewhat used to the GUI idiom where when I type something wrong in a text input field a balloon pops up from the field with info about what I got wrong / expected input. It remains visible until I type again. But now I couldn't find any example to point to.

给定一个JTextfield你知道任何显示这样气球的库/代码吗？由我的keylistener触发？

Given a JTextfield do you know of any library/code that would display such a balloon when triggered by my keylistener?

推荐答案

Balloon Tip 就是这样做的一个库：

Balloon Tip is a library that does that:

balloonTip = new BalloonTip(f, "Tooltip msg");

这就是全部所需！如果你坚持让它成为工具提示：

That was all needed! If you insist on a having it be a tooltip too:

tooltipBalloon = new BalloonTip(someComponent, "I'm a balloon tooltip!");
// Now convert this balloon tip to a tooltip, such that the tooltip shows up after 500 milliseconds and stays visible for 3000 milliseconds
ToolTipUtils.balloonToToolTip(tooltipBalloon, 500, 3000);
