MATLAB: Changing slider limit in gui

Question

is there anyway i could get the slider to update the limit to the image count Ct?

It seems that the app.Slider.Limits only accepts numerical values – at the moment it is set at 2. How can in incorperate the .Count function into the slider limit so the limit automatically updates with the value of .Count should i decide to import another file with a different .Count value?

How can I add a listener function here also?

Imported imageSet code

    % Button pushed function: LoadImageButton
        function LoadImageButtonPushed(app, event)
            global Ct
            imgSetVector = imageSet(uigetdir(''),'recursive');
             Z = read(imgSetVector,1);
             Ct = imgSetVector.Count;
imshow(Z,'Parent',app.UIAxes)

Slider Code

     app.Slider = uislider(app.UIFigure);
            app.Slider.Limits = [1 2]; **
            app.Slider.MajorTicks = [];
            app.Slider.MajorTickLabels = {''};
            app.Slider.ValueChangedFcn = createCallbackFcn(app, @SliderValueChanged, true);
            app.Slider.MinorTicks = [];
            app.Slider.Position = [296 36 321 3];
            app.Slider.Value = 1;

Thanks!

Try to set the slider limit after this line

Ct = imgSetVector.Count;
app.Slider.Limits(2) = Ct;
