Slider (legacy) with no room to slide?

I would like to create a slider (legacy version) to select a whole number from 1 to a given n.

For n >= 2 this is OK, the cursor is of size 1/n of the width of the slider, so every step it moves 1 unit coherently,.

figure;
for n = 2:7 % n = 1 ?
    pos = [0.1, (n-1)*0.1, 0.8, 0.04];
    uicontrol('style','slide','unit', ...
        'normalized', 'position', pos,...
        'Min', 1, 'Max', n, 'value', 1, 'sliderstep', 1/(n-1)+[0 0], ...
        'BackgroundColor', [0 0 0], ...
        'Callback', @(h, varargin) disp("v=" + round(h.Value)));
end

Naturally for n=1, I would like cursor to be as large as the slider and it cannot move. Not sure how to set up such slider at the borderline. undocumented Java hack a la Yair is welcome.

As you can try my above code will not make MATLAB very happy for n=1.

For the record I put here some slide to document sliderstep from @the cyclist answer

I believe this does what you want, for N=1.

I frankly have not fully grokked how this works, but figured I'd post the solution anyway. I also didn't look for the most elegant way to not do this case as a one-off.

figure

for n = 2:7 % n = 1 ?
    pos = [0.1, (n-1)*0.1, 0.8, 0.04];
    uicontrol('style','slide','unit', ...
        'normalized', 'position', pos,...
        'Min', 1, 'Max', n, 'value', 1, 'sliderstep', 1/(n-1)+[0 0], ...
        'BackgroundColor', [0 0 0], ...
        'Callback', @(h, varargin) disp("v=" + round(h.Value)));
end

pos = [0.1, 0, 0.8, 0.04];
uicontrol('style','slide','unit', ...
    'normalized', 'position', pos,...
    'Min', 1, 'Max', 2, 'value', 1, 'sliderstep', [0 Inf], ... 
    'BackgroundColor', [0 0 0], ...
    'Callback', @(h, varargin) disp("v=" + round(h.Value)));

Oh yeah the trick is to put Inf in sliderstep(2) and something > 1 for Max.

I don't get it either but it's what I look for. Thanks.
