| Code Assist triggers for Java [message #245613] |

I'm trying to get the content assist to show automatically as you type (in
MS Visual studio) instead of calling it with a shortkey. I figured that
entering all alphabetical characters in the "Avto activation triggers for
Java" preference field wold do the trick, but the input text field is
sadly (and strangely) limited to only 4 characters.
Is there a way to achieve this behaviour without editing the source code?
I managed to bypass the text box limitation in the Eclipse PDT plugin by
editing the source code. I used File -> Inport -> Plugins and Fragments.
Since PDT has a source folder I could edit a file named
ContentAssistSupport.java and change autoActivationTriggers =
PreferenceConstants.getPreferenceStore().getString(Preferenc eConstants.CODEASSIST_AUTOACTIVATION_TRIGGERS_PHP).trim().to CharArray();
to my custom char array. Then I exported the modified code as a Deployable
plugin.
The problem with JDT is that there is no source folder included in my
installation and I can't figure out a way to obtain the JDT source folder
that would enable me to use the technique I used for PDT.
I'm using eclipse europa.
I would appreciate any help in this matter.
Regards,
Matej

Here is a method that seems to work but you'll have to edit some jface
code.
The file to change is:
/org.eclipse.jface.text/src/org/eclipse/jface/text/contentas sist/CompletionProposalPopup.java

Not sure what you mean here. Simply either import the org.eclipse.jdt.ui
source or load it via CVS (dev.eclipse.org).
