The ContextHitTestInfoEnum type defines areas of
the host. The
HitTest
property determines the host' objects that can be accessed at current cursor location.
For instance, if the
HitTest property
includes the
exHTValidColumn flag, it indicates that the cursor hovers a column, and the
Column
property gives the index of the column from the cursor. The ContextHitTestInfoEnum
