code completion with additional information - how? [message #230308]

Hi!

I have noticed on a couple of screenshots and videos on the Net that, when
using code completion, it is possible to get additional information by means
of an additional window that opens up to the right, displaying information
on the item selected in the list of completions. For example, this can be
seen here:

What do I have to do to get that?

Many thanks.
Dominik

Hi,

It looks to me like simple javadoc for the selected element. All you
need for it is to have either the source or the javadocs for the .jar
file from which the element is coming.

Scanning through the Preference pages I couldn't found an option which
enables or disables this. So, I think all you need is the CodeComplete
feature enabled.

Note that it only works off Javadoc if you use a newer 3.2 build, e.g.
3.2 RC6.

Correct.

I am currently using Eclipse 3.1.2, so I can only use the source option
without upgrading... but how do I tell Eclipse where to look for the JDK
source? (It works fine with sources that are part of the project and contain
javadoc)

cheers!

Select the JAR to which you want to attach source and open its property
dialog via context menu. You can then set the source and the Javadoc
location.

If I want the popup information for the JDK, do I really have to do this for
every project? Because for some reason, it's not possible to change the
source location or javadoc location for the JRE jars globally under
Preferences/Installed JREs/...
In the project settings, it can be done, but doing that for every project
would get a little tedious.

bye,

It is a little different for JDKs/JREs.

Hope this helps,
