## @deftypefn {Function File} {@var{h} =} gco ()
## @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 @qcode{"CurrentObject"} property of the target figure.
##
## If the last mouse click did not occur on any child object of the figure,
## then the current object is the figure itself.
##
## If no mouse click occurred in the target figure, this function returns an
## empty matrix.
##
## Programming Note: The value returned by this function is not necessarily the
## same as the one returned by @code{gcbo} during callback execution. An
## executing callback can be interrupted by another callback and the current
## object may be changed.
