Java Content Assist in a View [message #1003614]

Hi,

I don't know if it is the correct project to post about this. Sorry if not.

I'm implementing a plugin consisting on a view, that requires Java content assist. The view includes a small window where java code is typed and evaluated. Same as the Display view in Debug mode.
I've searched a lot in the web, but couldn't find any help on this.

Is there any way this can be accomplished?

Thanks

Agustin

For example the New Java Class wizard offers this to enter a superclass.
I suggest you take a look at
org.eclipse.jdt.ui.wizards.NewTypeWizardPage.createSuperClassControls(Composite,
int)
<http://git.eclipse.org/c/jdt/eclipse.jdt.ui.git/plain/org.eclipse.jdt.ui/ui/org/eclipse/jdt/ui/wizards/NewTypeWizardPage.java>
as an entry point.

Hi,

You need to create am ICompilationUnit from your source-file and then
invoke ICompilationUnit.codeComplete()

I've used it in an experiment I did with orion's editor, see
https://github.com/tomsontom/fx-ide/blob/master/at.bestsolution.javafx.ide.jdt/src/at/bestsolution/javafx/ide/jdt/internal/JavaEditor.java

I'm not an expert in the JDT so I might use things completely wrong but
maybe it helps.

Thanks for the answers, I'll take a look. My main problem is that my input is an String(containing the code) and not a file and I'm not using editors, but SourceViewer (AFAIK an editor works internally with a SourceViewer) so I guess I will need to do some plumbing here.

Just to you to get a better idea what I'm trying to accomplish, I'm writing a plugin for running JPA queries (JPQL and Criteria). Basically, there is a tab where you can write some Java code using the JPA Criteria API and evaluate it. I want to add content assist for that, so it facilitates the coding.
I'll try to play around ICompilationUnit.
