Java Editor Stand-alone Widget [message #545820]

Hi,
I am looking for the Java Editor functionality (particularly syntax highlighting, code completion and error markers) as a stand-alone widget, which can be placed on other arbitrary controls. I want to use the widget, for example in a view, a dialog or even within another FormEditor.

Do you know how something similar could be done? Any hints would be helpful.

I hope there is a way to do it, without having to implement all the functionality using SourceViewer Controls

Use a SourceViewer and configure it using
org.eclipse.jdt.ui.text.JavaSourceViewerConfiguration. However, you need
to wire most of the actions yourself.

Thanks a lot Dani.

JavaSourceViewerConfiguration requires an ITextEditor.. which I don't have, when working in a dialog or a view.

The JavaSourceViewerConfiguration seems to be applicable only to proper editors and not to SourceViewers.

Am I missing any important clue here?

No, it does not.

I am also thinking about this topic. What I want to do is to integrate Java Editor into my IDE and only one method body is shown every time.
Some has been done as below.
//Create a JavaEditor ,since internal class is used, I am find some new solution. So far the answer is NO

private void createJavaEditor(Composite parent){
//Java editor part
javaEditor = new CompilationUnitEditor();
try{
javaEditor.init(this.getEditorSite(),this.getEditorInput());
}catch(Exception e){
e.printStackTrace();
}
Composite composite = new Composite(parent, javaEditor.getOrientation());
composite .setLayout(new FillLayout());
composite .setLayoutData(new GridData(GridData.FILL_BOTH));
javaEditor.createPartControl(composite );
}

The Java editor already supports this out of the box (Java > Editor: [x]
Only show the selected Java element.

Hi Dani,

I'm pretty sure it expects an ITextEditor in its constructor. Basically
any interesting method is guarded with if (getEditor() != null) ..
How can I use a JavaSourceViewerConfiguration without an editor?

Regards,
Sebastian

I am on the side of Florian. I still can't figure out how Dani wanted us to create a JavaSourceViewerConfiguration without a proper editor.

Would it be possible to have a code snippet of using the java editor in a dialog?

TF

* @param editor the editor in which the configured viewer(s) will
reside, or <code>null</code> if none
*/
public JavaSourceViewerConfiguration(IColorManager colorManager,
IPreferenceStore preferenceStore, ITextEditor editor, String partitioning) {

Which part of this Javadoc don't you get? I didn't say that all
functionality will be available but it gives you basic Java viewer
functionality which is e.g. also used in the JDT preference previews.

Hi Dani,
Thanks for the clue about the JDT preference pages. I could get the previewer functionality by copying a few lines from:

org.eclipse.jdt.internal.ui.preferences.formatter.JavaPrevie w
