Ancestor of graphics object


p = ancestor(h,type)
p = ancestor(h,type,'toplevel')


p = ancestor(h,type) returns the handle of the closest ancestor of h, if the ancestor is one of the types of graphics objects specified by type. type can be:

  • a character vector with the name of a single type of object, for example, 'figure'.

  • a cell array containing the names of multiple objects, for example, {'hgtransform','hggroup','axes'}.

If MATLAB® cannot find an ancestor of h that is one of the specified types, then ancestor returns p as empty. When ancestor searches the hierarchy, it includes the object itself in the search. Therefore, if the object with handle h is of one of the types listed in type, ancestor will return object h.

ancestor returns p as empty but does not issue an error if h is not a graphics object.

p = ancestor(h,type,'toplevel') returns the highest-level ancestor of h, if this type appears in the type argument.


Find the ancestors of a line object:

% Create some line objects and parent them 
% to an hggroup object.
hgg = hggroup;
hgl = line(randn(5),randn(5),'Parent',hgg);
% Now get the ancestor of the lines:
p = ancestor(hgg,{'figure','axes','hggroup'});
% Now get the top-level ancestor:
