如何获取Java工具提示的大小 [英] How to get size of Java tooltip

问题描述

我有一个组件，其中 getToolTipText(MouseEvent) 返回一些 HTML，因此它的格式很好(包括显示多行).但是我想放置工具提示(通过覆盖 getToolTipLocation(MouseEvent))以确保它不在窗口的某些部分上，为此我需要知道工具提示的尺寸.有没有办法做到这一点?

I have a Component where getToolTipText(MouseEvent) returns some HTML so it's nicely formatted (including showing multiple lines). However I want to place the tooltip (by overriding getToolTipLocation(MouseEvent)) to try to make sure it isn't over certain parts of the window, and to do that I need to know the dimensions the tooltip will have. Is there a way I can do this?

推荐答案

javax.swing.JToolTip 从 javax.swing.JComponent<继承 getPreferredSize()/code> 以便您可以执行以下操作:

javax.swing.JToolTip inherits getPreferredSize() from javax.swing.JComponent so you can do something like:

Dimension d = myToolTip.getPreferredSize();

并在您的 getToolTipLocation(MouseEvent)
