Multipage Editor with Xtext [message #894444]

Mon, 09 July 2012 05:25

I would like to use my Xtext editor in a multi-page editor (created with the wizard through Eclipse RCP).

In fact, I'd like to know how to call my Xtext editor in my multi-page one.
I know where all my ui stuff is in my project but I can't find the right class.

I need to call it as :

XtextEditor myXtextEditor = new XtextEditor();

Anyone has infos about this ?

I also saw that there's an EmbeddedEditor object in the Xtext Javadoc, but there's no documentation on it and I can't find any information through the web about it.

Thanks.

The class is correct, but you have to create the XtextEditor using the
Google Guice Injector of your language.

Usually you do this by creating some anchor class (e.g. your multi-page
editor) that's registered in the plugin.xml with the
ExecutableExtensionFactory of you language and have all needed
properties injected (recursively) using the @Inject annotation.

See
http://www.eclipse.org/Xtext/documentation.html##equinoxSetup
for details, or have a look at how the UI plug-in of your language
registers the editor.

An uglier alternative is to obtain the injector from the Activator of
your language's UI plug-in and call

injector.getInstance(XtextEditor.class)

to create the editor.

Thank you for your response.

I tried the uglier way with injector but unfortunately it doesn't work for me.

For the official alternative, I already saw this possibility but I thought it was not possible for my case.
I have some questions about it.

In my multi-page editor project I have the following extension :

 <extension
         point="org.eclipse.ui.editors">
      <editor
            name="Sample Multi-page Editor"
            extensions="mpe"
            icon="icons/sample.gif"
            contributorClass="multieditor.editors.MultiPageEditorContributor"
            class="multieditor.editors.MultiPageEditor"
            id="multieditor.editors.MultiPageEditor">
      </editor>
  </extension>

And here I implement the MultiPageEditor class to create different tabs, for example.

I read your link, so I guess I have to write a new extension in my plug-in as :

   
 <extension point="org.eclipse.ui.editors">
    <editor
    class="<MyDsl>ExecutableExtensionFactory:
    org.eclipse.xtext.ui.editor.XtextEditor"
    contributorClass=
    "org.eclipse.ui.editors.text.TextEditorActionContributor"
    default="true"
    extensions="mydsl"
    id="org.eclipse.xtext.example.MyDsl"
    name="MyDsl Editor">
    </editor>
  </extension>

But the thing I don't understand is how can I use it after this. I see the @Inject annotation but I can't see how to use it in this case.

In fact, my use case is to create a dsl editor for my language with 2 tabs (like multi-page editor). I already finish my dsl editor with Xtext (great framework by the way) and I would like to create a second tab in this one.

And yes I'm quite new to Xtext, so any ints would be helpful, thanks Smile

I found a previous thread about this, I'll try with the example provided in :

Ok I found a solution, I don't know if this is the best way but it works.
I post here some lines, maybe it will help someone out there.

Injector myInjector = MyModelActivator.getInstance().getInjector(
					 "org.my.package.MyModel");
xtextEditor = myInjector.getInstance(XtextEditor.class);

I put this code in a method called createPageX(), on my multi-page editor project created with the wizard.

Looks like my second proposal ;-)

By the way, I got an issue with the Outline View with this method.
In the multi-page editor, it says that "An Outline view is not available".

As I called my XtextEditor, did the outline view is automatically called either ?

Your Multipage Editor has either to be adaptable to the
(Xtext-?)OutlineView or the Xtext editor. I'm not 100% sure. But it's
pretty basic Eclipse editor API and I sure you'll figure that out in one
newsgroup / forum or another.

Sebastian

Thank you for your response.

Indeed I talk about my Xtext OutlineView. So I guess I have to personalize the standard outline of multi-page editor in order to have the same OutlineView as a simple Xtext editor.

Hi,
I managed to get it

http://wiki.eclipse.org/FAQ_How_do_I_create_an_Outline_view_for_my_own_language_editor%3F

so as per the eclipse FAQ I simply added this to my MPE


@Inject
OutlinePaje outlinePage;

@Inject
XtextEditor xtextEditor;

@Override
public Object getAdapter(Class adapter) {
	
 if (IContentOutlinePage.class.equals(adapter)) {
    
    outlinePage.setSourceViewer(
        xtextEditor.getInternalSourceViewer());

    return outlinePage;
 }
 return super.getAdapter(adapter);
		
}

I can appreciate the power of injection, now.

cheers
Ste
