to return tooltip text for itself. This implementation calls 1 of 5 methods
to obtain the text based upon the horizontal location of the mouse:
getToolTipStartText
is called if the mouse
is near the start time of the activity graphic.getToolTipEndText
is called if the mouse
is near the end time of the activity graphic.getToolTipCenterText
is called
when the mouse is not near the ends of the activity graphic.null
, then the
text set by calling IlvActivityGraphicRenderer.setToolTipText(java.lang.String)
will be used.null
, then the

is obtained from the renderer's underlying graphic
