Examples with Position org.eclipse.jface.text.Position used on opensource projects

Example 21 with Position

use of org.eclipse.jface.text.Position in project xtext-eclipse by eclipse.

the class AnnotationWithQuickFixesHover method getHoverInfoInternal.

// DIFF: this code is entirely different, as the hover subclasses from AbstractProblemHover and
// hooks different methods
