Hello,

I am a beginner in Xtext. I want to add markers programmatically to my editor, and I've done it thanks to the following method :

private void createInformativeMarker(IAnnotationModelExtension extension, XtextEditor editor) {
		Issue.IssueImpl issue = new Issue.IssueImpl();
		INode node = NodeModelUtils.findActualNodeFor(associatedObject);
		int start = node.getOffset();
		int length = node.getLength();
		int line = node.getStartLine();
		issue.setSyntaxError(false);
		issue.setSeverity(Severity.INFO);
		issue.setLineNumber(line);
		issue.setMessage(markerInformation());
		String type = "org.eclipse.xtext.ui.editor.info";
		XtextAnnotation rangeIndicator = new XtextAnnotation(type, true, editor.getDocument(),issue, false);
		this.annotation = rangeIndicator;
		extension.modifyAnnotationPosition(rangeIndicator, new Position(start, length));
	}

The type I provided seems to be the information icon. I wanted to know if it was possible to provide my own icons to this marker ? Simply giving the image path does not seem to do the trick.

Thanks !

Hi

The XtextAnnotation.getImages() method demonstrates icon switching. However it is private, so you probably need to create a derived XtextAnnotation that overrides the paint() method from which getImages() is called.
