I just started using the App Designer for MATLAB and was wondering if there was a mouse wheel scroll function similar to one for GUI's. Specifically to change the values of a knob or slider component. Here's a preview of my code:
function CutoffFrequencyHzSliderValueChanging(app, event)
changingValue = event.Value;
app.EditField.Value = changingValue;
selectedButton = app.TrackingTypeButtonGroup.SelectedObject;
track = selectedButton.Text;
value = app.DropDown.Value;
% set(app.CutoffFrequencyHzSlider,'windowscrollWheelFcn',{@scrollfunc,gca})
% b = uicontrol('Style','WindowScrollWheel','Callback',{@eindoedscrollwheel_callback,gcf});
clear leg
file = app.(value);
data = file.(track);
.......
The 2 lines that are commented out are 2 separate attempts at adding scroll wheel functionality to my slider component.
