Save event XtextEditor [message #756575]

Hi,

I'm wondering where I could find/customize/overwrite the doSave() method of an xtext editor, which was created in the classical way in Eclipse (New->Xtext Project). What I want to do is write some information in a file upon saving the model of the xtext editor. Due to the automatically generated structure of the editor, there is no explicit class, which extends the EditorPart and implements the doSave(), isDirty() etc. methods - the class where I could eventually write some data/preferences to a file.

Any help is kindly apreciated.

You should create an implementation of IXtextEditorCallback and bind it like this in your <LanguageName>UIModule

public void configureMySpecialSaveHook(com.google.inject.Binder binder) {
binder.bind(IXtextEditorCallback.class).annotatedWith(Names.named("SpecialSaveHook")).to(
MySpecialSaveHook.class);
}

Thank you for the hint, Sven. Here's what I did (and it works like I want it to):

I created my own XtextEditorCallback like this:

public class MyDSLXtextEditorCallback extends AbstractDirtyStateAwareEditorCallback {

	@Override
	public void afterSave(XtextEditor editor) {
		System.out.println("Saved!");
	}
}

and then I bound it in the <LanguageName>UIModule like this:

public void configureMyDSLXtextEditorCallback(com.google.inject.Binder binder) {
	binder.bind(IXtextEditorCallback.class).annotatedWith(Names.named("MyDSLXtextEditorCallback")).to(MyDSLXtextEditorCallback.class);
}

Thank you very much for your help!

This should be easy:

In the afterSave() method I would need the org.eclipse.emf.common.util.URI of the resource previously saved. How can I get it?

Thanks for your help in advance!

Hi,

i am not quite sure what you want to do
never the less:
- call XtextEditor.getResource get an IResource and use std mechanims to calc the emf uri
- use XtextEditor.getDocument.readOnly/XtextEditor.getDocument.readOnly/modify
