Method Detail

create

public static PlayHeadMarker create()

Returns the unique instance of PlayHeadMarker.

Returns:

The unique instance of PlayHeadMarker.

containsPoint

public boolean containsPoint(java.awt.Point p)

Description copied from class: Marker

Checks whether the marker display area contains the given point. Markers not interested in mouse clicks may always return false.

Overrides:

containsPoint in class Marker

Parameters:

p - The point to check

Returns:

true if the marker "hotspot" contains the point.

startDrag

public void startDrag()

called back from drag mode to say when we started dragging for real (at least a short distance)

endDrag

private void endDrag(boolean reset)

reinstate the old map mode after switching temporarily to do a play head drag

Parameters:

reset - whether to reset state (pause audio and restore old coordinates)

drag

public void drag(EastNorth en)

apply the new position resulting from a drag in progress

Parameters:

en - the new position in map terms

reposition

public void reposition(EastNorth en)

reposition the play head at the point on the track nearest position given, providing we are within reasonable distance from the track; otherwise reset to the original position.

Parameters:

en - the position to start looking from

synchronize

public void synchronize(EastNorth en)

Synchronize the audio at the position where the play head was paused before dragging with the position on the track where it was dropped. If this is quite near an audio marker, we use that marker as the sync. location, otherwise we create a new marker at the trackpoint nearest the end point of the drag point to apply the sync to.

Parameters:

en - : the EastNorth end point of the drag

paint

public void paint(java.awt.Graphics g,
                  MapView mv)

Paint the marker icon in the given graphics context.

Parameters:

g - The graphics context

mv - The map

animate

public void animate()

Animates the marker along the track.

timerAction

public void timerAction()

callback for moving play head marker according to audio player position
