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 string that is 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.
Note that ancestor returns p as empty but does not issue an error if h is not the handle of a Handle Graphics object.
p = ancestor(h,type,'toplevel') returns the highest-level ancestor of h, if this type appears in the type argument.
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'});
get(p,'Type')
ans =
hggroupNow get the top-level ancestor
p=ancestor(hgg,{'figure','axes','hggroup'},'toplevel');
get(p,'type')
ans =
