How To Migrate / Connect an Uicontrol Spinner Function To GUI created by GUIDE

Dear Community,

I have a question about how to connect Uicontrol Function of Spinner to be displayed in my GUI created by GUIDE. I just so confused because GUIDE didnt provide a spinner and it provided by App Designer Matlab. I just want to create a spinner by a function and display it on my GUIDE.

And this is an example of spinner function i get from internet :

function [obj] = uispinner(varargin)
%UISPINNER GUI Control to accept a scalar for the user
%   The spinner has up/down buttons which the user can press to
%   adjust the value with the mouse. The callback is continuously
%   called as he does this.
%       'Min' - minimum value (default 0)
%       'Max' - maximum value (default 1)
%       'Step' - increment (default 0.01)
%       'Position' - position matrix
%       'Value' - the initial value (default 0)
%       'Format' - printf format controls display of value (default '%g')
%       'Callback' - callback of form (hObject, eventdata, value ...)
%          (callback is called continuous as users spins the spinner. 
%           Extra arguments can be passed in a cell array.)
%
% Example use uispinner('Max' 100, 'Step', 1, 'Format' '%03d', ...
%             'Callback', {@spinme, 'Fred', 'Bloggs'})
%
% function spinme(hOBject, eventdata, value, opt)
%             fprintf(1, '%s %s is spun to %f\n', opt{1}, opt{2}, value);
%          end

val  = 0;
min = 0;
max = 1;
step = 0.01;
pos = [80 80 100 25];
callback = [];
fmt = '%g';

for ii =1:2:nargin
    if(ii == nargin)
        error('option without value (%s)', varargin{ii});
    end
    if(strcmpi(varargin{ii}, 'Value'))
        val = varargin{ii+1};
    elseif(strcmpi(varargin{ii}, 'Min'))
        min = varargin{ii+1};
    elseif(strcmpi(varargin{ii}, 'Max'))
        max = varargin{ii+1};
    elseif(strcmpi(varargin{ii}, 'Step'))
        step = varargin{ii+1};
    elseif(strcmpi(varargin{ii}, 'Position'))
        pos = varargin{ii+1};
    elseif(strcmpi(varargin{ii}, 'Callback'))
        callback = varargin{ii+1};
    elseif(strcmpi(varargin{ii}, 'Format'))
        fmt = varargin{ii+1};
    else
        error('Urecognised option %s', varargin{ii});
    end
end

if(val < min)
    val = min;
end
if(val > max)
    val = max;
end

obj = uipanel('Position', pos);
hedit = uicontrol('Style', 'edit', 'String', sprintf(fmt, val), ...
    'Position', [pos(1), pos(2), pos(3)-10, pos(4)], 'Callback', @edited, ...
    'BackgroundColor', 'white');
if(step ~= 0 && min < max)
    sstep = [step/(max-min) 0.1];
else
    sstep = [0.001 0.1];
end
if(max > min)
    sval = (val-min)/(max-min);
else
    sval = 0;
end
hslider = uicontrol('Style', 'slider', ...
'Position', [pos(1)+pos(3)-10, pos(2), 10, pos(4)], ...
    'Callback', @slide, 'SliderStep', sstep, 'Value', sval);

if(iscell(callback))
    cbdata = callback;
    callback = cbdata{1};
    cbdata(1) = [];
else
    cbdata = [];
end
s = struct('hedit', hedit, 'hslider', hslider, 'min', min, 'max', max, ...
    'val', val, 'step', step, 'callback', callback, ...
    'cbdata', {cbdata}, 'fmt', fmt);
set(obj, 'UserData', s);
set(hslider, 'UserData', obj);
set(hedit, 'UserData', obj);


function slide(hObject, eventdata)
    t = get(hObject, 'Value');
    hpanel = get(hObject, 'UserData');
    s = get(hpanel, 'UserData');
    v = s.min + (s.max-s.min)*t;
    if(s.step ~= 0)
        v = v - mod(v, s.step);
    end
    if(s.step == fix(s.step))
        v = floor(v + 0.5);
    end
    set(s.hedit, 'String', sprintf(s.fmt, v));
    s.val = v;   
    set(hpanel, 'UserData', s);
    if(isempty(s.callback))
        return;
    elseif(isempty(s.cbdata))
        s.callback(hpanel, [], s.val);
    else
        s.callback(hpanel, [], s.val, s.cbdata);
    end


function edited(hObject, eventdata)
    t = get(hObject, 'String');
    hpanel = get(hObject, 'UserData');
    s = get(hpanel, 'Userdata');
    v = str2double(t);
    if(isnan(v) || v < s.min || v > s.max)
        set(s.hedit, 'String', sprintf(s.fmt, s.val));
    else
        if(s.step ~= 0)
            v = v - mod(v, s.step);
        end
        s.val = v;
        set(s.hedit, 'String', sprintf(s.fmt, s.val));
        set(hpanel, 'UserData', s);
        set(s.hslider, 'Value',  (v - s.min) /(s.max-s.min));
        if(isempty(s.callback))
            return;
        elseif(isempty(s.cbdata))
            s.callback(hpanel, [], s.val);
        else
            s.callback(hpanel, [], s.val, s.cbdata);
        end
    end
         

If the code above is running, then the result would be like this :

The spinner would appear in Figure 1 Uipanel. In my question, i want to migrate and put the spinner in Figure 1 to FMI_methods.fig (the first picture) as one of handles structure in it.... Would anyone help me out to find the code or the solution? Iam very grateful if anyone can solve my problem.... Thank you so much.... /.\ /.\ /.\

What you want is not possible with the builtin uispinner function. As its documentation states the parent can only be a uifigure or one of its decendants. It is thus not possible to implement it in a GUIDE-created GUI.

If you have an implementation from someone else, you should ask them for usage examples. It is also a good idea to avoid the function names Matlab has chosen, so you should probably rename the function if you actually intend to use it.

Also, you shouldn't be using GUIDE. For general advice and examples for how to create a GUI (and avoid using GUIDE), have look at this thread.

@Rik Thank so much, Sir..

I actually already found the spinner function specially for GUIDE-created GUI. It was created by Matlab Staff, Steven in this link : https://www.mathworks.com/matlabcentral/fileexchange/5881-spinner

But i still confused how the spin response to a new data (non-numeric), like datetime string, for my case.

would u like to help me, Sir? Thanks... My brain already blown up just for this...

[Rik]

The spinner is composed of an edit field and two buttons. The edit field can display text, so you can rig it to display a date as well (e.g. with the datestr function). You will also have to change the increment/decrement functions to first convert the date to a number, then add or subtract the step, then convert back to a char vector.

@Rik Thank you so much, iam following your HINTS, and it work. Logic , Debug, and Behavior is The Key of all programming language, thought....
