I am writing a GUI function. Some uicontrols need to switch their position in certain cases. So I wrote a nested function, to switch their positions if needed.
But it turned out, that their positions were only switched in the nest function. Outside the nested function, they kept their previous positions.
So how to change the UI's properties by functions?
To make it simple, my functions were as following.
function main_func()
h = figure();
b1 = uicontrol(h, 'some properties', 'Position', p1);
b2 = uicontrol(h, 'some properties', 'Position', p2);
switchPosition();
function switchPosition()
set(b1, 'Position', p2);
set(b2, 'Position', p1);
end
end
I also tried function with b1 and b2 as the input variables, but it didn't work either.

Try this
function switchPosition(b1, b2)
pos1 = b1.Position;
pos2 = b2.Position;
b1.Position = pos2;
b2.Position = pos1;
end
