Bug 25370 Linked Mode: Want to define where to focus
20021022 I added a new feature that starts the linked mode on all usages of a variable. e.g. int i; i= 1; i++; would link all 3 occurrences of i, so when edited, all 3 references are changed simultanously. Problem is that the liked mode does not allow me to set the focus (where to edit) to e.g. the 'i' in 'i++'. The linked mode only allows to edit the top most linked position ('int i'). The feature can be invoked on any reference. Jumping to the top not so ideal.

private void initializeHighlightColor(ITextViewer viewer) {
		if (fFrameColor != null)
			fFrameColor.dispose();
		StyledText text= viewer.getTextWidget();
		if (text != null) {
			Display display= text.getDisplay();
			fFrameColor= createColor(fgStore, PreferenceConstants.EDITOR_LINKED_POSITION_COLOR, display);
		}
	}
	/**

	private Color createColor(IPreferenceStore store, String key, Display display) {
	
		RGB rgb= null;		
		
		if (store.contains(key)) {
			
			if (store.isDefault(key))
				rgb= PreferenceConverter.getDefaultColor(store, key);
			else
				rgb= PreferenceConverter.getColor(store, key);
		
			if (rgb != null)
				return new Color(display, rgb);
		}
		
		return null;
