## @deftypefnx {Function File} {@var{h} =} gco (@var{fig})
## Return a handle to the current object of the current figure, or a handle
## to the current object of the figure with handle @var{fig}.  The current
## object of a figure is the object that was last clicked on.  It is stored
## in the CurrentObject property of the target figure.
##
## If the last mouse click didn't occur on any child object of the figure,
## the current object is the figure itself.
##
## If no mouse click occured in the target figure, this function returns an
## empty matrix.
##
## Note that the value returned by this function is not necessarily the same
## as the one returned by gcbo during callback execution.  An executing
## callback can be interrupted by another callback and the current object
## can be modified.
