MATLAB: SET with a dynamic function handle

Question

Hello,

I want to use the SET command inside a while loop, with the function handle changing each time through. Namely, I have a few listboxes (tagged listbox1, listbox2, listbox3 etc.) and based on a numerical condition, I want only up to a certain number of them to remain visible. This doesn't work, but may provide a better idea of what I'm shooting for:

%get the handles of all listboxes, get the corresponding tags
allHandleList = findobj('style','listbox')
allTagList = get(allHandleList,'Tag')%get the tags of all those handles
    handles.numCores = str2double(getenv('Number_of_processors'))
    n=1;
    while n<=handles.numCores
%make a function handle based on each tag
      fhandle=str2func(['handles.' allTagList{n}]) 
%use that function handle to change a PropertyValue
      set(fhandle(),'Visible','off') 
      n=n+1; %update count variable
  end

Answer 1

No need to make a function handle.

fhandle = handles.(allTagList{n});
set(fhandle, 'Visible', 'off');
