Hi,

It's taken me some time to finally get my XtextEditor running in a TitleAreaDialog:

| *public **void *run(IAction action)
{
*try*
{
*final *XtextEditor editor = *new *XtextEditor()
{
@Override
*protected *IStatusLineManager getStatusLineManager()
{
*return null*;
}
};

Injector injector = MyDslActivator.getInstance().getInjector("org.xtext.example.mydsl.MyDsl ");
injector.injectMembers(editor);

IEditorSite site = *new *DummySite();
IFile file = *new *DummyFile();
editor.init(site, *new *FileEditorInput(file));

Dialog dialog = *new *TitleAreaDialog(window.getShell())
{
@Override
*protected *Control createDialogArea(Composite parent)
{
Composite area = (Composite)*super*.createDialogArea(parent);
Composite contents = *new *Composite(area, SWT.NONE);
contents.setLayout(*new *FillLayout());
contents.setLayoutData(*new *GridData(SWT.FILL, SWT.FILL, true, *true*));

setTitle("MYDSL");
setMessage("Enter an expression.");

editor.createPartControl(contents);
*return *area;
}
};

dialog.open();
}
*catch *(Exception ex)
{
ex.printStackTrace();
}
}|


The dialog properly shows the default content that I provide via DummyFile.getContents(). Unfortunately the text area seems to be read-only and I can absolutley not find out why. Would you say the whole approach is odd or do you have an immediate idea?

I've attached the full code as a zip in case you wanna try it out. See SampleAction.java

Cheers

Does it work if you feed it a real IFile resource instead of the
DummyFile instance?

Should have tested that before! Yes, it does work then.

Unfortunately I still have no clue what in my DummyFile cauase the editor to think that it's read-only, nor how I can find that out ;-(

I'm willing to create temp files outside of the workspace as a means of communication buffer between the dialog and the application:

| File tempFile = File.createTempFile("xtext-", ".tmp");
IFileStore fileStore = EFS.getLocalFileSystem().getStore(tempFile.toURI());
editor.init(*new *DummySite(), *new *FileStoreEditorInput(fileStore));|


Unfortunately that leads to an exception:

I.e. here:

ElementInfo info = super.createElementInfo(element);
XtextDocument doc = (XtextDocument) info.fDocument;
AnnotationIssueProcessor annotationIssueProcessor = new AnnotationIssueProcessor(doc, info.fModel, issueResolutionProvider);
ValidationJob job = new ValidationJob(resourceValidator, doc, annotationIssueProcessor,CheckMode.FAST_ONLY);
*doc.setValidationJob(job);*
return info;
}

I'd really prefer not to create temp files somewhere in the workspace ;-(

Hi Eike,

did you try the approach that was used here:
http://code.google.com/a/eclipselabs.org/p/xtext-forms-integ ration/source/browse/#svn/trunk/plugins/org.eclipselabs.xtfo .demo.rcp/src/org/eclipselabs/xtfo/demo/rcp/partialEditing
?
It uses a SourceViewer instead of a full editor and is thereby more
flexible, e.g. you do not need a physical file to edit a resource.

Regards,
Sebastian

Hi Sebastian,

Yes, I've looked at it but it's a whole lot of UI code () most of it probably being already in the XtextEditor) and I do not see that I'd be able to maintain that. Nor can I pretend that I even understand most of it.

Is there really no easy and built-in way to use Xtext without an EditorPart?

Cheers

Hi Sebastian,<br>
<br>
Yes, I've looked at it but it's a whole lot of UI code () most of it
probably being already in the XtextEditor) and I do not see that I'd
be able to maintain that. Nor can I pretend that I even understand
most of it.<br>
<br>
Is there really no easy and built-in way to use Xtext without an
EditorPart?<br>
<br>

It uses a SourceViewer instead of a full editor and is thereby
more flexible, e.g. you do not need a physical file to edit a
resource.

Hi Eike,

there will be an easy way in the next version of Xtext but so long
you'll either have to hassle with the UI stuff or with the editor
framework of Eclipse.
Creating temporary files outside of your workspace will lead to other
problems as well, e.g. the global visibility rules have to tailored if
the resource does not reside in an IProject ...

Regards,
Sebastian

I'd be happy with I/S-builds if only I have not to wait until Indigo GA ;-)

I've made some progress with my editor approach. This works:

| IStorage storage = *new *TempStorage("test.mydsl", "is project");
editor.init(*new *DummySite(), *new *StorageEditorInput(storage));|


With:

| *public final class *TempStorage *extends *PlatformObject *implements *IEncodedStorage
{
*private *String name;

*private *String contents;

*public *TempStorage(String name, String contents)
{
*this*.name = name;
*this*.contents = contents;
}

*public *String getName()
{
*return *name;
}

*public *InputStream getContents() *throws *CoreException
{
*return new *ByteArrayInputStream(contents.getBytes());
}

*public *IPath getFullPath()
{
*return new *Path(name).makeAbsolute();
}

*public **boolean *isReadOnly()
{
*return false*;
}

*public *String getCharset() *throws *CoreException
{
*return *"UTF-8";
}
}|


And:

| *public class *StorageEditorInput *extends *PlatformObject *implements *IStorageEditorInput
{
*private *IStorage storage;

*public *StorageEditorInput(IStorage storage)
{
*this*.storage = storage;
}

*public *IStorage getStorage() *throws *CoreException
{
*return *storage;
}

*public **boolean *exists()
{
*return true*;
}

*public *String getName()
{
*return *storage.getName();
}

*public *ImageDescriptor getImageDescriptor()
{
*return null*;
}

*public *String getToolTipText()
{
*return null*;
}

*public *IPersistableElement getPersistable()
{
*return null*;
}
}|


Further I had to adjust my Guice module:

| *public class *MyDslUiModule *extends *org.xtext.example.mydsl.ui.AbstractMyDslUiModule
{
*public *MyDslUiModule(AbstractUIPlugin plugin)
{
*super*(plugin);
}

@Override
*public *Class<? *extends *IXtextEditorCallback> bindIXtextEditorCallback()
{
*return _null_*;
}

@Override
*public *Class<? *extends *IResourceForEditorInputFactory> bindIResourceForEditorInputFactory()
{
* *_*return TempStorageResourceForIEditorInputFactory.class;*_
}

*public static class *TempStorageResourceForIEditorInputFactory *extends *ResourceForIEditorInputFactory
{
@Override
*protected *Resource createResource(IStorage storage) *throws *CoreException
{
*if *(storage *instanceof *TempStorage)
{
*return *createResourceFor((TempStorage)storage);
}

*return super*.createResource(storage);
}

*protected *Resource createResourceFor(TempStorage storage) *throws *CoreException
{
ResourceSet resourceSet = getResourceSet(storage);
URI uri = _*URI.createFileURI*__*(storage.getName());*_
configureResourceSet(resourceSet, uri);
XtextResource resource = createResource(resourceSet, uri);
resource.setValidationDisabled(_*true*_);
*return *resource;
}
}
}|


Nevertheless I run into problems because the annotationModel is null. I'm currently trying to apply some minor changes to o.e.xtext.ui to be a little more tolerant against non-IFile based resources...

Cheers
/Eike

Okay, I've given up on my EditorPart based approach and instead succeeded to use the code you pointed me to ;-)

However that code is also not immediately prepared to run outside of an editor. I had to add some not-null checks:

| *public **void *focusLost(FocusEvent e)
{
_*if (fContextActivation != null)*_
{
IContextService contextService = (IContextService)getActiveEditor().getSite().getService(ICon textService.*class*);
contextService.deactivateContext(fContextActivation);
}

IHandlerService handlerService = (IHandlerService)PlatformUI.getWorkbench().getAdapter(IHandl erService.*class*);
handlerService.deactivateHandlers(fHandlerActivations);
}

*public **void *focusGained(FocusEvent e)
{
IEditorPart editor = getActiveEditor();
_*if (editor != null)*_
{
IContextService contextService = (IContextService)editor.getSite().getService(IContextService .*class*);
fContextActivation = contextService.activateContext(EMBEDEDXTEXT_EDITOR_CONTEXT);
}

IHandlerService handlerService = (IHandlerService)PlatformUI.getWorkbench().getAdapter(IHandl erService.*class*);

*for *(ActionHandler actionHandler : fActionHandlers)
{
fHandlerActivations.add(handlerService.activateHandler(actio nHandler.getAction().getId(), actionHandler,
fExpression));
}
}|


I wonder if someone is interested in these minor changes (Cedric?)...

Cheers
/Eike
