Sliders in Matlab GUI

I am trying to enable my slider to scroll up and down the GUI window. The code is below if you dont mine running it you'll see that Im trying to only scroll the panel named mount model correction parameters and the content within it

function varargout = ACModel(varargin)

gui_Singleton = 1;

gui_State = struct('gui_Name', mfilename, ...

                   'gui_Singleton',  gui_Singleton, ...

                   'gui_OpeningFcn', @ACModel_OpeningFcn, ...

                   'gui_OutputFcn',  @ACModel_OutputFcn, ...

                   'gui_LayoutFcn',  [] , ...

                   'gui_Callback',   []);

if nargin && ischar(varargin{1})

    gui_State.gui_Callback = str2func(varargin{1});

end

if nargout

    [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});

else

    gui_mainfcn(gui_State, varargin{:});

end

function ACModel_OpeningFcn(hObject, eventdata, handles, varargin)

handles.output = hObject;

guidata(hObject, handles);

function varargout = ACModel_OutputFcn(hObject, eventdata, handles)

varargout{1} = handles.output;

function Add_Callback(hObject, eventdata, handles)

function Browse_Callback(hObject, eventdata, handles)

function Filename_Callback(hObject, eventdata, handles)

function Filename_CreateFcn(hObject, eventdata, handles)

if ispc && isequal(get(hObject,'BackgroundColor'),

get(0,'defaultUicontrolBackgroundColor'))

    set(hObject,'BackgroundColor','white');

end

function TS_Callback(hObject, eventdata, handles)

function TC_Callback(hObject, eventdata, handles)

function TC_CreateFcn(hObject, eventdata, handles)

if ispc && isequal(get(hObject,'BackgroundColor'),

get(0,'defaultUicontrolBackgroundColor'))

    set(hObject,'BackgroundColor','white');

end

function SelectGraph_Callback(hObject, eventdata, handles)

function SelectGraph_CreateFcn(hObject, eventdata, handles)

if ispc && isequal(get(hObject,'BackgroundColor'),

get(0,'defaultUicontrolBackgroundColor'))

    set(hObject,'BackgroundColor','white');

end

function Calculate_Callback(hObject, eventdata, handles)

function slider4_Callback(hObject, eventdata, handles)

n = get(handles.TC,'Value');

set(handles.slider4,'Value',n);

function slider4_CreateFcn(hObject, eventdata, handles)

if isequal(get(hObject,'BackgroundColor'),

 get(0,'defaultUicontrolBackgroundColor'))

    set(hObject,'BackgroundColor',[.9 .9 .9]);

end

Check out this simple function.. you should be able to copy and paste it into a new file, save the file with the name simpleProgrammaticSlider.m, and execute it. It should provide us with some code and functionality to begin discussions that are more specific. Have a look, and let me/others looking at this post what clarifications can be made.

function simpleProgrammaticSlider

    % SIMPLEPROGRAMMATICSLIDER shows a plot of a line y = m*x + b and allows
    % the user to change m by moving a slider.

    % when the slider is at 1, m = mMax
    mMax = 5;
    % when the slider is at 0, m = mMin
    mMin = -5;
    % initial value for m
    m = mMax;
    % initial value for b
    b = 1;
    % specify limits for axes 
    axLimits = [-2,2,-5,5];

    x = linspace(-2,2);
    y = m*x+b;

    % create figure and position it
    f = figure('toolbar','none',...
               'menubar','none',...
               'Position',[680, 678, 560, 300]);

    % create axes and position it         
    axes('Position',[.5 .15 .4 .75]);

    % add initial plot and fix axis limits
    plot(x,y);
    axis(axLimits);

    % add slider to figure
    s1h = uicontrol('Style',    'slider',...
                    'Units',    'Normalized',...
                    'Value',    1,...
                    'Position', [.15,.15,.1,.8],...
                    'Callback', @sliderCallback);

    % this nested function is called every time the slider is clicked
    function sliderCallback(hObj,~)
      sv = get(hObj,'Value'); % slider value between 0 and 1
      m = sv*(mMax-mMin) + mMin; % new slope of the line
      y = m*x+b;
      plot(x,y);
      axis(axLimits);
    end                         
end

thank you very much for the function. Being that you have a graph it is easier to define the Max and Min; I am trying to get my slider to scroll up and down my GUI just like a the sliders scrolls up and down the page your on.

So I have no idea how to identify the max and min values for the scroll.

[Kye Taylor]

What are you trying to have your slider do? It sounds like you want your slider to actually scroll the contents of the gui, rather than change a parameter. Is that correct?

[Cordelle]

I am trying to enable my slider to scroll sub-panels and the contents within the sub-panels. I have only gotten the slider to scroll the contents within the sub-panel but i want the sub-panel to scroll along with the contents within it

[Kye Taylor]

I do not follow you.

The slider can be used to position either 1.) the contents of the sub-panel, or 2.) the contents of the GUI (the sub-panel itself).

Are you trying 1.) or 2.)?

[Cordelle]

2.)
