This line causes the "no items to choose from warning":
fh=menu;
The reason this is working at all is because you are changing the root property (i.e. MATLAB base property) screenpixelsperinch
This happens because
fh = menu
returns 0, the root identifier. To get the behavior you want:
ii=1;
while ii==1
oldSPPI = get(0,'screenpixelsperinch'); %store old one
set(0,'screenpixelsperinch',200); %increase - will affect everything
kk = menu('choose','me','no me!','go home it''s Friday!');
set(0,'screenpixelsperinch',oldSPPI); %restore
figure;
plot(1:10,1:10),grid
title('Test Plot')
if kk==1
break
end
end
Thus the reason it affects everything, is, well you're changing MATLAB's settings.
If this functionality is really important to you, I suggest you write your own menu function and increase the fontsize of the uicontrols manually. See Matt Fig's demos:
