print figure shows hidden objects

I have a gui that I created without using guide. There are various configurations, and I switch between them by hiding gui elements. This works great up until the user tries to do a screen print, where this piece of code from "prepare.m" is invoked by the "print" function:

%Need to see everything when printing hiddenH = get( 0, 'showhiddenhandles' ); set( 0, 'showhiddenhandles', 'on' )

Not clear why we need to see everything when printing, makes no sense to me. If I want to show the hidden handles, I'd make them visible. Any suggestions?

I see there is a bug report http://www.mathworks.com/support/bugreports/308433

"set(0, 'showhiddenhandles', 'on')" does not make anything visible. It allows to include the handles a.g. when getting the children of an HG-object. See also:

docsearch ShowHiddenHandles
docsearch HandleVisibility

What problems do occur when printing?

that just means I didn't find the right line of code. This program shows the behavior I have seeing. When you open the jpeg, you get a surprise.

function bugshowD

h_main = figure('name', 'bugshowD', ...
    'Visible', 'on', ...
    'OuterPosition', [200 200 360 360]);

hprintbutton = uicontrol(h_main, ...
            'Style', 'pushbutton', ...
            'Position', [10 10 70 70], ...
            'String', 'Print',...
            'Callback', @printsave);
hpanel =   uipanel('Parent', h_main, ...
                                'Position',[ 110 110  240 240], ...
                                'Title', 'Panel',...
                                'visible','off');
hhiddenbutton = uicontrol(hpanel, ...
            'Style', 'pushbutton', ...
            'Position', [5 5 70 70], ...
            'String', 'neverseen',...
            'Callback', @nothing,...
            'visible','on');

function printsave(windowname,~)

         [ffile, fpath, findex] = uiputfile( ...
                  {'*.jpg', 'jpeg file (*.jpg)';
                  '*.eps', 'encapsulated postscript file (*.eps)'},...
                  'save screen capture', 'screenprint');
          print(['-f' num2str(h_main)], fullfile(fpath, ffile), '-djpeg80', '-r300')         

end
end

I'd just like to add that when I wrote this little program, and omitted the uipanel, that it didn't show the hidden button. This makes me think that it's just a bug with hidden uipanels. This behavior also shows up if you use printdlg
