Integer scalar (or two-element vector for a Trackbar)
Valid for: Progress, Spinner, Trackbar
The increment property contains the amount by which the control's value will change when the user clicks on one of the buttons of a Spinner control, or when the StepIt method is called for a Progress bar. For a Trackbar, it is a two-element vector; the first element is the 'page' increment, and the second is the 'line' increment.
