Not working - Hover on variable to see value in debug prespective in Eclipse
提问by troy
I am using classic Eclipse 3.6.1. I have a Java project which is throwing an exception because of a stack overflow. Unlike other editors, when I hover my mouse pointer on a variable it does not show me the value of that variable. Here are the settings in
我使用的是经典的 Eclipse 3.6.1。我有一个 Java 项目，由于堆栈溢出而引发异常。与其他编辑器不同，当我将鼠标指针悬停在变量上时，它不会显示该变量的值。这里是设置
Window->Preferences->Java->Editor->Hovers
Combined Hover - Shift
Variable Values - Ctrl
Source - Shift+Ctrl
But this doesn't seem to be working. I have seen threads by others about this same problem but could not find a solution. Is this a bug that hasn't been fixed yet?
但这似乎不起作用。我看过其他人关于同一问题的帖子，但找不到解决方案。这是一个尚未修复的错误吗？
Thanks!
谢谢！

Go to Window - Preferences - Java - Editor - Hovers.
转到窗口 - 首选项 - Java - 编辑器 - 悬停。
Is "Combined Hover" selected? Uncheck it; apply; close the window; restart debugging session; go back; check it again; apply.
If the above doesn't help, you can check "Variable Values" option and specify a modifier key for it. Not as convenient as "combined", but should work.
The problem gets "fixed" by renaming the package.
通过重命名包，问题得到“修复”。
For whatever reason, this refactoring triggers something in Eclipse, and immediately I was able to view variable values during debugging. Also, when I go back into Preferences under Hovers, I can now see the "Variable Values" option.
无论出于何种原因，这种重构都会触发 Eclipse 中的某些内容，并且我立即能够在调试期间查看变量值。此外，当我回到悬停下的首选项时，我现在可以看到“变量值”选项。

In my case Preferences under Hovers were checked and enabled. Even after that it was not showing values when I move the mouse on the variable. Problem has been fixed by simply closing and reopening the Eclipse (I was using Eclipse with Python).
在我的情况下，选中并启用了悬停下的首选项。即使在那之后，当我在变量上移动鼠标时它也没有显示值。问题已通过简单地关闭并重新打开 Eclipse（我使用 Eclipse 和 Python）来解决。
