Hi FTs,

Recently I updated to Fieldtrip version 20150115 (was using 2014
Septemper version earlier) which resulted in a GUI error in the Matlab
command window <http://bugzilla.fcdonders.nl/show_bug.cgi?id=2819#>
when any buttons in the interactive window were clicked. The GUI which
I activated was cfg.artfctdefvalue.zvalue.interactive = 'yes';

I believe this error arises only on the Matlab2014b version since the
error was not reproduced in Matlab2014a version.  Given below is the
error that was displayed:


showing trial   1, channel Cz
No appropriate method, property, or field Key for class

Error in ft_artifact_zvalue>parseKeyboardEvent (line 1079)
key = eventdata.Key;

Error in ft_artifact_zvalue>keyboard_cb (line 680)
  key = parseKeyboardEvent(eventdata);

Error using waitfor
Error while evaluating UIControl Callback

                cfg.continuous = 'yes';
                cfg.trl = trl_2;

                cfg.artfctdef.zvalue.channel    = data.label{jj};
                cfg.artfctdef.zvalue.cutoff     = 8;
                cfg.artfctdef.zvalue.trlpadding = 0;
                cfg.artfctdef.zvalue.artpadding = 0.05;
                cfg.artfctdef.zvalue.fltpadding = 0;

                cfg.artfctdef.zvalue.cumulative    = 'yes';
                cfg.artfctdef.zvalue.medianfilter  = 'yes';
                cfg.artfctdef.zvalue.medianfiltord = 9;
                cfg.artfctdef.zvalue.absdiff       = 'yes';

                cfg.artfctdef.zvalue.interactive = 'yes';


P.S. - I was aware of Bug2461
<http://bugzilla.fcdonders.nl/show_bug.cgi?id=2461> and that is why I
upgraded to the latest FT version since a post dated this month states
that FT had partially resolved the issues from Handle graphics 2.
