Constructor Details

DraggableRectangle

public DraggableRectangle()

Method Details

isDraggingPrimed

public boolean isDraggingPrimed()

Specified by:

isDraggingPrimed in interface Draggable

Returns:

whether a press has primed a possible drag

isDragging

public boolean isDragging()

Specified by:

isDragging in interface Draggable

Returns:

whether a drag is currently active

setDraggingPrimed

public void setDraggingPrimed(boolean primed)

Specified by:

setDraggingPrimed in interface Draggable

Parameters:

primed - whether a possible drag is primed

setDragging

public void setDragging(boolean dragging)

Specified by:

setDragging in interface Draggable

Parameters:

dragging - whether a drag is active; setting this to true marks the overlay as having been moved (see implementation notes on "been moved" tracking)

setCurrentPoint

public void setCurrentPoint(Point p)

Specified by:

setCurrentPoint in interface Draggable

Parameters:

p - current screen point, or null

getCurrentPoint

public Point getCurrentPoint()

Specified by:

getCurrentPoint in interface Draggable

Returns:

defensive copy of the current screen point, or null
