XText TextViewer instead of Editor [message #875558]

Tue, 22 May 2012 20:40

Eclipse User

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.

Sebastian

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?

Vlad

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

Thanks a lot, a code example was more than I expected as an answer! Smile

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
