[Octave-bug-tracker] [bug #44242] Adding a listener to the "children" property has no effect

[Pantxo Diribarne]

Follow-up Comment #9, bug #44242 (project octave):

Hi,

The attached patch fixes the issue for me. Using listeners on axes children
property is a bit noisy (e.g. Octave internally deletes recreates text labels
when "nextplot" is "replace"):


>> clf ();
>> hax = axes ();
>> fcn = @() disp ("Children modified");
>> addlistener (hax, "children", fcn);
>> plot (rand (3))
Children modified
Children modified
Children modified
Children modified
Children modified
Children modified
Children modified
>> hold all
>> plot (rand (3))
Children modified
Children modified
Children modified
>> h = get (gca (), "children");
>> set (gca (), "children", flipud (h))
Children modified
 

(file #33111)
