1 view (last 30 days)
i have 16 objects, with tag 'box1,box2,box3.....' What i want is for the loop to access each of the objects and alter its property, either Color or any other property. how do i do this within a loop.
rcolour is just a custom function you can ignore it
for i=1:16 bcolour=rcolour() handles.box(i).BackgroundColor=bcolour; end

If you want to do it like this, you can access structure fields using strings by enclosing the string referring to the fieldname in brackets. For your case:
for i = 1:16
str = sprintf('box%d',i);
handles.(str).BackgroundColor = bcolor; %
end
