发帖数: 238 | 2 There is one thing that I cannot figure out in Eclipse.
How to use IntelliSence in eclipse IDE. That is when I put the mouse point
over a method's name, the IDE should pop-up a tip/context about the method's
comments document. Also, when you writer a method, it provides the method's
signature with the parameters' names rather than something like arg0 in
eclipse.
It is supported by at least MS Visual studio and Jbuilder.
I tried several times to put th java api documents in different directories. |

I've told you, read JPDA carefully. Eclipse is fully complaint with the spec.
Although the spec is used for developing a debugger, you can understand how
IDE tools like Eclipse and Netbeans hook up to an application, set break point
and trace the workflow.

标 题: Help: how to use Eclipse as C++ IDE in XP?
发信站: BBS 未名空间站 (Mon Jan 7 21:04:22 2008)
I've already download and installed Eclipse. Then I realized there's no C++
compiler installed in XP. So I googled and found it seemed MinGW would help.
However, after installing MinGW, I still cannot compile a simple "hello,
world" code.
Anyone can give suggestions, or give links about step-by-step instructions

但是换到Linux下，import了叫new的那个版本，第一级的目录名显示的就是最上层

为在Linux的Eclipse中，它也会把最上层目录用包名表示（因为和new的那个一样了，
所以命名冲突不能导入）。
我想知道的是，是我哪里设错了，还是Linux下的Eclipse比较不flexible？
