Class HapticViewPort

  • java.lang.Object
    • uk.ac.qmul.eecs.depic.daw.haptics.HapticViewPort

  • public class HapticViewPort
extends java.lang.Object
    The haptic viewport is the specific portion of a track that is visible in the haptic view in every moment. It uses the same concept of a scrollable window: if the content is to big to be represented in a single window, then you only represent a portion of it and allow the user to scroll up and down. Likewise the haptic view port only represent one portion of audio track at the time and when the haptic proxy gets to the left or right ends of the view port, then the viewport is shifted of a certain amount of pixels.
