targetWidget |
targetWidget a tkwin object for the target
tcltk widget to which a tool tip will be associated |

Given a target tcltk widget, a tooltip will be associated with the widget. The content of the tooltip will be shown when mouse moves over the widget and disappear when mouse moves out of the widget.

This function is part of the Bioconductor project at Dana-Farber Cancer Institute to provide Bioinformatics functionalities through R
