getToolTipText

                             IlvTransformer t)

This method is called by an activity graphic 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.
• Otherwise, getToolTipCenterText is called when the mouse is not near the ends of the activity graphic.
• If any of the previous 3 methods returns null, then the text set by calling IlvActivityGraphicRenderer.setToolTipText(java.lang.String) will be used.
• If the 4 previous methods returned null, then the tooltip text is obtained from the renderer's underlying graphic.

Specified by:

getToolTipText in interface IlvActivityRenderer

Overrides:

getToolTipText in class IlvActivityGraphicRenderer

Parameters:

ag - The activity graphic.

p - The location of the mouse (in view coordinates).

t - The transformer.

Returns:

The tooltip text.
