Hi,

I would like to have a custom View which allows users to code/assist Java
code. I would like to take advantage of the already existing
functionality in the JavaEditor from the JDT project for code
assist/syntax.

The problem for me is that don't must be an open JavaEditor in the
workbench and I only want to see the code snippet in the View.

How J use: JavaContentAssistInvocationContext,
CompletionProposalLabelProvider or other ..... in simple mode?

There is a example for simple view java using code assist?

Help Me!

Thanks in advanced!

To get all JDT proposals is not possible without the editor. What you
can get are the proposals returned by JDT Core. If that's enough for you
I can give you some hints.

Hi,

j'm confuse :(

As I must build a little TextEditor for Java, with code completion as
its main functionality.
I mustnt build a plugin but a simple TextEditor (simple view) that is
opened with a click on a button of a RCP application, could you please
give me advice more specifically on the techniques used for Java code
completion code assist (org.eclipse.jface.text or
org.eclipse.jdt.ui.text.java or ........).

Thanks in advanced.

Help me!

JDT Core offers standard Java code completion but the Java editor has
more: it e.g. shows template proposals and proposals contributed by
other plug-ins via extension point.

The JDT is a very large feature with lots of components. I doubt the
content-assist portion is something that can be extracted from the rest
of JDT and used by itself - it is just too dependent on the other
infrastrcture of JDT (for example, the Abstract Syntax Tree, the Java
Project nature, etc). You would probably be better off trying to get the
JDT to work in an RCP and then use its editor as your "simple view."

Hi,

I think that my problem has no simple solution :((

I must build a little and simple TextEditor that is opened with a click
on a button of a RCP application for BeanShell or Java, with code
completion as its main functionality.

I found out this plug-in
http://www.eclipseplugincentral.com/Web_Links-index-req-view link-cid-582.html
that could be useful to me but is not very simple modify the source code.

j think other solution its use java package org.eclipse.jdt,
org.eclipse.jdt.ui.text.java ...... to take advantage of the already
existing
functionality in the JavaEditor.
But I dont'n think the content-assist portion is something that can be
extracted from the rest of JDT and used by itself - it is just too
dependent on the other infrastrcture of JDT.

In old post j find this: " A better way would be to more or less copy the
contents of JavaSourceViewerConfiguration::getContentAssistant.
Instead of the JavaCompletionProcessors you could create your own
ContentAssistProcessor subclass (since you don't seem to mind using
internal code...) that does not require an editor. To create a
JavaContentAssistInvocationContext, use its constructor taking a
compilation unit." But for me at moment is complex... J dont't find any
java source code
for help me.......

:(

Thank you very much

See you
