  • Method Details

    • setDraggableElements

      public void setDraggableElements(int mask)
      Sets the Draggable elements - the Horizontal or Vertical Direction. One

      can use a bitmasked 'or' (HORIZONTAL_SCROLL_BAR | VERTICAL_SCROLL_BAR ).

      Parameters:
      mask - One of HORIZONTAL_SCROLL_BAR, VERTICAL_SCROLL_BAR, or HORIZONTAL_SCROLL_BAR | VERTICAL_SCROLL_BAR

    • setScrollingIntensity

      public void setScrollingIntensity(int intensity)
      Sets the scrolling intensity - the default value being 5. Note, that this has an

      inverse relationship to intensity (1 has the biggest difference, higher numbers having

      less impact).

      Parameters:
      intensity - The new intensity value (Note the inverse relationship).

    • setAnimationTiming

      public void setAnimationTiming(int timing)
      Sets how frequently the animation will occur in milliseconds. Default

      value is 30 milliseconds. 60+ will get a bit flickery.

      Parameters:
      timing - The timing, in milliseconds.

    • setDamping

      public void setDamping(double damping)
      Sets the animation damping.
      Parameters:
      damping - The new value
