Hi,

I wish to attach a ModifyListener to the XTextEditor, the first time it gains focus (or some time prior to editing, such as on opening?). Is there any part of the XText API that could/should be used to achieve this?

Did you have a look at org.eclipse.xtext.ui.editor.IXtextEditorCallback

Hi,
I've been able to achieve the desired effect by extending NatureAddingEditorCallback, but imagine there's probably a better way to do this. There were runtime errors when I tried to attach a second IXtextEditorCallback, saying the there could only be one callback. How would I add another?

public class CustomXtextEditorCallback extends
NatureAddingEditorCallback {

@Override
public void afterCreatePartControl(XtextEditor editor) {
super.afterCreatePartControl(editor);
setup(editor);
}

private void setup(XtextEditor editor) {
StyledText textWidget = editor.getInternalSourceViewer().getTextWidget();

ModifyListener eventBListener = RodinKeyboardPlugin.getDefault()
.createRodinModifyListener();
textWidget.addModifyListener(eventBListener);
}

}

Hi,

i cannot reproduce that

	public void configureXtextEditorCallbacks(Binder binder) {
		binder.bind(IXtextEditorCallback.class).annotatedWith(Names.named("dontcare1")).to(XtextEditorCallback1.class);
		binder.bind(IXtextEditorCallback.class).annotatedWith(Names.named("dontcare2")).to(XtextEditorCallback2.class);
	}

works fine for me

That worked for me too: It's just difficult to find out how to do these things when you're not familiar with the technology. Thanks for your assistance.
