IsOverNode( )
The IsOverNode method is used to detect a node location to pass to the drilldown procedure. A drilldown graph control is normally selected by doubleclicking on a selected node, but the IsOverNode method allows node data to be passed when selecting a drilldown graph from the popup menu.
IsOverNode returns TRUE when a valid node was in range when the mouse right-click was pressed. If the user right-clicks over an area where no node is present, the “Drilldown” or “Return from DrillDown” menu options will be disabled.
Return Data Type: BOOL
Implementation:
The IsOverNode method is called from the CalcPopup method.
