MATLAB: App designer: Enable mouse scroll to change value on slider

app designerscrollslider

In the app designer: Is it possible to change the value on the slider by scrolling? Or possibly by using arrows on the keyboard?

Best Answer

Take a look at the UIFigure's following properties:
  • WindowScrollWheelFcn
  • WindowKeyPressFcn
  • WindowKeyReleasedFcn
If you need these only to work while the mouse is over the slider element, you can test the mouse's location with hittest().
