Hello, I would like to know how I can make a slider 'passive'. Passive means the slider will move to show progress but the user cannot adjust or move the slider. This will make the slider move like in movie player but not clickable or drag-able. Can I do that? Thanks!

Hi!
First of all, you have to open the slider's options and set 'Enable' to 'inactive', so the user cannot change the slider's position. Then, to set the position of the slider, you use its handle:
newvalue = 0.5;
set(handles.slider1,'Value',newvalue);

In order to use the handles in another function, you have to pass it as an argument to the updateslider function:
function pushbutton1_Callback(hObject, eventdata, handles)
hTEST = getappdata (0, 'hTEST');
updateSlider(handles);
function updateSlider(handles)
hTEST = getappdata (0 , 'hTEST' );
sliderValue = getappdata (hTEST, 'currentNum');
set (handles.slider1, 'Value' , sliderValue)
