XText TextViewer instead of Editor [message #875558] Wed, 23 May 2012 00:40 Go to next message
Eclipse UserFriend
Hi,

Have created a simple query language to use with a BIRT ODA driver.

Instead of using the XText generated Editor for my query language, I
will need to present the user with a TextViewer in the DataSet Wizard in
order to specify the query string.

I am still a novice when it comes to XText, but I did look but haven't
found any documentation, examples or newsgroup entries regarding a use
case like this.

Can anyone give me an example on how to go about doing this.

thanks,
John

Hi John,
I don't know if it will fits your needs but you can use a plugin provided by the guys of Itemis, used in the Yakindu project.
They provide a JFace integration plugin and more stuff too.
I used it in my project (simply used the StyledTextXtextAdapter class). It worked fine.

More information can be found watching this video tutorial took from the latest EclipseCon Europe.
hxxp://www.fosslc.org/drupal/content/tmf-meets-gmf-combining-graphical-and-textual-modeling

Repository for the yakindu project is here:
hxxp://code.google.com/a/eclipselabs.org/p/yakindu/

You can checkout their code and have a look.
You can install the integration features you need using this update site
hxxp://updates.yakindu.com/indigo/milestones

Hope this helps.
Massimo.

John,

if you use Xtext 2.3, you may want to have a look at the
EmbeddedEditorFactory.

Hi Massimo,

Yes, that worked great!

I did the same as you and used the StyledTextXtextAdapter with a StyleText.

The video tutorial was very informative as well.

thanks much,

John

Hi Sebastian,

Would that be the recommended way to use an Xtext editor in a multi-page one too?

Hi Vlad,

I'd try something along these lines:

public class MultiPageEditor extends MultiPageEditorPart {

@Inject
private Provider<XtextEditor> editorProvider;

private XtextEditor editor;

@Override
protected void createPages() {
try {
editor = editorProvider.get();
int index = addPage(editor, getEditorInput());
setPageText(index, editor.getTitle());
} catch (PartInitException e) {
ErrorDialog.openError(
getSite().getShell(),
"Error creating nested text editor",
null,
e.getStatus());
}
}

@Override
public void doSave(IProgressMonitor monitor) {
editor.doSave(monitor);
}

@Override
public void doSaveAs() {
editor.doSaveAs();
setPageText(0, editor.getTitle());
setInput(editor.getEditorInput());
}

@Override
public boolean isSaveAsAllowed() {
return true;
}

}

The EmbeddedEditorFActory should be used to embed an editor in a
composite that is not an IEditorPart itself.

Regards,
Sebastian

Hi at all,

does it work also on Eclipse 4?

I don't understand what I have to put in my @PostContruct method to see the xtext editor.

Very thank you.

I made several steps ahead from yesterday.

Now I've got this doubt: in my part I have to insert a code like this:
StyledText styledText=new StyledText(parent, SWT.BORDER);
		StyledTextXtextAdapter xtextAdapter=new StyledTextXtextAdapter(getInjector());
xtextAdapter.adapt(styledText);


what is "getInjector()"?

Basic Eclipse 4 injection or com.google.inject.Injector that use also in StyledTextXtextAdapter definition? How can I get it?

Thanks all.

Hi Tommaso,
I don't know where you get the code snippet you copy-pasted.
However the injector you need to pass there is an instance of com.google.inject.Injector. It should be the injector relative to your dsl language.
You can get this injector via the generated plugin class inside the generated ui XText project (method getInjector(String languageName)).

Regards,
Massimo.

Hi Sebastian

I did try to use the MPE eq: you have mentioned,

Quote:

public class MultiPageEditor extends MultiPageEditorPart {

@Inject
private Provider<XtextEditor> editorProvider;

private XtextEditor editor;


but for me editor = editorProvider.get(); was giving a null pointer exception

Is there anything else I need to do for the @Injector to populate the values for editorProvider.

Please let me know

Thanks
Kavitha

Hi Christian ,

Thanks for the link, it was really useful. I am able to add XtextEditor on a MultiPageEditor.

Now I have one more issue, I am trying to add the EMF editor as another page on the MPE where the XtextEditor is already added.

How can I link the EMF editor to the xtext input file (the dsl file).

Please let me know your comments.

Thanks,
Kavitha

Hi Guys,

Not sure if you still check the forum after 5 years or not Very Happy but could you please let me know how did you make the StyledTextXtextAdapter work ! The video also is deleted Sad

This is my code:
		IXtextFakeContextResourcesProvider contextProvider=new IXtextFakeContextResourcesProvider() {

			@Override
			public void populateFakeResourceSet(ResourceSet fakeResourceSet, XtextResource fakeResource) {
				fakeResource=xtextResource;
				fakeResourceSet=xtextResource.getResourceSet();			
			}
		};


		StyledTextXtextAdapter xTextAdaptor = new StyledTextXtextAdapter(xtextInjector,contextProvider);
		xTextAdaptor.adapt(shellContainer.styledText);


The functionality is there! The problem is that the textEditor is totally empty and it does not show me the particular object that I want from Model. When I press ctrl+space I get the root of the model ! As if there is nothing in the Xtext resource file.

I'd appreciate if you could help me on this,
Thanks,
Bests

Hi Christian,

Thank you for your reply, I am using the code from sirius+Xtext integration on github. I just changed the code a little bit to run with double click on the object rather than a java extension.

So, if you just take a look at the createXtextEditor() method, there is segment for creating EmbeddedEditor. I just removed this EmbeddedEditor and added my code for SttyledTextXtextAdapter. So, the xtextresource is created based on the semantic element that I pass to this class. It is Weird because it works fine for the EmbeddedEditor and shows the text for the semantic element, but when I use StyledXtextAdapter it doesn't work and gives me empty text editor as if resource is totally empty! I can use content assistant and coloring is working but I guess the resource is just not set ! Confused

BTW, can I use StyledXtextCellEditor instead of StyledXtextAdapter ? They are pretty much the same, right ?

Thanks a lot,
Best Regards,
Parsa

sry i have no idea on that how it is intended to be used.ntl this is what works for me

@Override
	public void createPartControl(Composite parent) {
		Model model = MyDslFactory.eINSTANCE.createModel();
		Greeting g1 = MyDslFactory.eINSTANCE.createGreeting();
		Greeting g2 = MyDslFactory.eINSTANCE.createGreeting();
		Greeting g3 = MyDslFactory.eINSTANCE.createGreeting();
		g1.setName("G1");
		g2.setName("G2");
		g3.setName("G3");
		model.getGreetings().add(g1);
		model.getGreetings().add(g2);
		model.getGreetings().add(g3);
		
		ByteArrayOutputStream out = new ByteArrayOutputStream();
		
		IXtextFakeContextResourcesProvider fake = new IXtextFakeContextResourcesProvider() {
			
			@Override
			public void populateFakeResourceSet(ResourceSet fakeResourceSet, XtextResource fakeResource) {
				
				fakeResource.getContents().add(model);
				
				try {
					fakeResource.save(out, SaveOptions.newBuilder().format().getOptions().toOptionsMap());
					fakeResource.reparse(new String(out.toByteArray(), Charsets.UTF_8));
					
				} catch (IOException e) {
					e.printStackTrace();
				}
			
			}
		};
		
		
		StyledTextXtextAdapter adapter = new StyledTextXtextAdapter(injector, fake );
		StyledText styledText = new StyledText(parent,SWT.NONE);
		adapter.adapt(styledText);
		ICompositeNode node = NodeModelUtils.findActualNodeFor(((Model)adapter.getFakeResourceContext().getFakeResource().getContents().get(0)).getGreetings().get(1));
		styledText.setText(new String(out.toByteArray(), Charsets.UTF_8));
		adapter.setVisibleRegion(node.getOffset(),  node.getLength());
	}

Thanks a lot Christian,

It is working now Smile Now I see how it works Smile

BTW, Do you know if I can embed this StyledTextAdapter in a label of a transition/edge? Currently I'm just showing this styledtext as a popup to the user, but I have seen in Yakindu they embedded sth like this into the label of the transition.

Thanks again,
Best Regards,
Parsa

Hi again Christian,

I found that the StyledXtextAdapter shows the full text of my DSL file perfectly. However, when I pass the offset and length of my node to the setVisibleRegion(), it throws the following error. And, I am sure that the length of file is OK and the offset exists. I tried to trace the code and found that when I pass the setVisibleRegion(1752,9) , it turns out to become (3503,-1752) somewhere inside and have no idea why ! I though you might have some idea !

Thanks,
Bests,
Parsa

No. You have to Debug. Do you Use a styledtext oder a styledtextex

Hi Christian,
Not sure what you mean by styledtextex, but I am using StyledText. my code is below. I found that this is related to the bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=352847

The bug is saying that offset = master.getLineOffset(line); should be changed to offset += master.getLineOffset(line); and in my case, I guess the it is the other way around !
	public void createPartControl(Composite parent, EObject elem) {

		ByteArrayOutputStream out = new ByteArrayOutputStream();

		IXtextFakeContextResourcesProvider fake = new
				IXtextFakeContextResourcesProvider() {

			@Override
			public void populateFakeResourceSet(ResourceSet fakeResourceSet,
					XtextResource fakeResource) {

				
				fakeResource.getContents().clear();
				fakeResource.getContents().add(EcoreUtil.getRootContainer(elem));

				try {
					fakeResource.save(out,
							SaveOptions.newBuilder().format().getOptions().toOptionsMap());
					fakeResource.reparse(new String(out.toByteArray(), Charsets.UTF_8));

				} catch (IOException e) {
					e.printStackTrace();
				}

			}
		};
		StyledTextXtextAdapter adapter=new StyledTextXtextAdapter(xtextInjector, fake);
		StyledText styledText = new StyledText(parent,SWT.WRAP );
		adapter.adapt(styledText);

		ICompositeNode node = NodeModelUtils.findActualNodeFor((adapter.getFakeResourceContext().getFakeResource().getEObject(semanticElementFragment)));
		String s =node.getText();
		

		styledText.setText(new String(out.toByteArray(), Charsets.UTF_8));
		
		adapter.setVisibleRegion((node.getOffset(), node.getLength()));
	}


and this is the code for XtextSourceViewer visible region:
/**
	 * Overwritten to handle offset properly.
	 */
	@Override
	protected boolean updateSlaveDocument(IDocument slaveDocument,
			int modelRangeOffset, int modelRangeLength)
			throws BadLocationException {
		if (slaveDocument instanceof ProjectionDocument) {
			ProjectionDocument projection = (ProjectionDocument) slaveDocument;

			int offset = modelRangeOffset;
			int length = modelRangeLength;

			if (!isProjectionMode()) {
				// mimic original TextViewer behavior
				IDocument master = projection.getMasterDocument();
				int line = master.getLineOfOffset(modelRangeOffset);
				offset += master.getLineOffset(line);
				length = (modelRangeOffset - offset) + modelRangeLength;
			}

			try {
				// fHandleProjectionChanges= false;
				setPrivateHandleProjectionChangesField(false);
				projection.replaceMasterDocumentRanges(offset, length);
			} finally {
				// fHandleProjectionChanges= true;
				setPrivateHandleProjectionChangesField(true);
			}
			return true;
		}
		return false;
	}


Just thought it might be useful to know !
Thanks,
Bests,
Parsa

Hi Christian,

I just disregarded the Yakindu implementation of set visible region and have written my own class to override the set visible region for my purpose and it is working perfectly Smile

Thanks,
Parsa
