Hi All,

I have created slider in MATLAB in GUI. I have about 100 image files. I was implementing slider to display images when moved back & forward.

My code:

SliderStep = [0.01 0.1];
Min = 1;
Max = 100;
sliderVal = round(get(hObject, 'Value'));
set(hObject, 'Value', sliderVal);

My problem is when ever I move the file the slider. It shows either Min/Max is out of range and slider gets disabled or not shown in GUI.

Please help.

Regards,
Kuldeep

Hi Kuldeep,

You define the slider step and max / min, but you never actually assign those values to the properties of your object. You'll need to add a few lines of code:
set(hObject, 'SliderStep', SliderStep);
set(hObject, 'Min', Min);
set(hObject, 'Max', Max);

Hopefully that will work for you.

Set all three of these properties, as well as a starting value for the
position of the slider (which must be between Min and Max inclusive) in one
call to SET.

set(hObject, 'SliderStep', SliderStep, ...
'Min', Min, ...
'Max', Max, ...
'Value', Min); % or Max, or (Min+Max)/2, or some other value where Min
<= value and value <= Max is satisfied.
