public class SwipeTracker extends PropertyHolder
A swipe tracker used in [class@Carousel], [class@NavigationView] and
[class@OverlaySplitView].

The `AdwSwipeTracker` object can be used for implementing widgets with swipe
gestures. It supports touch-based swipes, pointer dragging, and touchpad
scrolling.

The widgets will probably want to expose the [property@SwipeTracker:enabled]
property. If they expect to use horizontal orientation,
[property@SwipeTracker:reversed] can be used for supporting RTL text
direction.

      public boolean getUpperOvershoot()
      Gets whether to allow swiping past the last available snap point.
      Gibt zurück:
      whether to allow swiping past the last available snap point

    • setAllowLongSwipes

      public void setAllowLongSwipes(boolean allow_long_swipes)
      Sets whether to allow swiping for more than one snap point at a time.

      If the value is `FALSE`, each swipe can only move to the adjacent snap
      points.
      Parameter:
      allow_long_swipes - whether to allow long swipes

    • setAllowMouseDrag

      public void setAllowMouseDrag(boolean allow_mouse_drag)
      Sets whether @self can be dragged with mouse pointer.
      Parameter:
      allow_mouse_drag - whether to allow mouse dragging

    • setAllowWindowHandle

      public void setAllowWindowHandle(boolean allow_window_handle)
      Sets whether to allow touchscreen swiping from `GtkWindowHandle`.

      Setting it to `TRUE` will make dragging the window impossible.
      Parameter:
      allow_window_handle - whether to allow swiping from window handles

    • setEnabled

      public void setEnabled(boolean enabled)
      Sets whether @self is enabled.

      When it's not enabled, no events will be processed. Usually widgets will want
      to expose this via a property.
      Parameter:
      enabled - whether @self is enabled

    • setLowerOvershoot

      public void setLowerOvershoot(boolean overshoot)
      Sets whether to allow swiping past the first available snap point.
      Parameter:
      overshoot - whether to allow swiping past the first available snap point

    • setReversed

      public void setReversed(boolean reversed)
      Sets whether to reverse the swipe direction.

      If the swipe tracker is horizontal, it can be used for supporting RTL text
      direction.
      Parameter:
      reversed - whether to reverse the swipe direction

    • setUpperOvershoot

      public void setUpperOvershoot(boolean overshoot)
      Sets whether to allow swiping past the last available snap point.
      Parameter:
      overshoot - whether to allow swiping past the last available snap point

    • shiftPosition

      public void shiftPosition(double delta)
      Moves the current progress value by @delta.

      This can be used to adjust the current position if snap points move during
      the gesture.
      Parameter:
      delta - the position delta
