ancestor - Ancestor of graphics object
Syntax
p = ancestor(h,type)
p = ancestor(h,type,'toplevel')
Description
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.
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.
Examples
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'});
get(p,'Type')
% Now get the top-level ancestor:
ptop=ancestor(hgg,{'figure','axes','hggroup'},'toplevel');
get(ptop,'type')
