[cdt-dev] Hover facility

[Venkataramana_Jaladurgam <Venkataramana_Jaladurgam@xxxxxxxxxx>]

Hello,
  I wanted to implement a custom hover facility for my editor which extends
CEditor.
  For testing, I have overridden the following function in my source viewer
configuration.

	public ITextHover getTextHover(ISourceViewer sourceViewer, String
contentType, int stateMask) 
	{
		return null;
	}
	
	public ITextHover getTextHover(ISourceViewer sourceViewer, String
contentType) 
	{
		return null;
	}
	public IAnnotationHover getAnnotationHover(ISourceViewer
sourceViewer) {
		return null;
	}
	
	public int[] getConfiguredTextHoverStateMasks(ISourceViewer
sourceViewer, String contentType) 
	{
		return null;
	}

  With this I expected that there should be not be any hover. But the hover
still comes. 
  Appreciate if someone throws light on the problem. How the hovering
facility is implemented in CDT.
  I need this very urgent. Pls. help
