Parameters:

pane - the source map pane

event - the source mouse event

MapMouseEvent

public MapMouseEvent(MapPane pane,
                     MouseWheelEvent event)

Creates a new event instance for a mouse wheel event.

Parameters:

pane - the source map pane

event - the source mouse wheel event

Method Detail

getSource

public MapPane getSource()

Gets the source map pane for this event.

Overrides:

getSource in class EventObject

isWheelEvent

public boolean isWheelEvent()

Queries whether this event was generated by a mouse wheel action.

Returns:

if a mouse event

getWheelAmount

public int getWheelAmount()

Gets the wheel travel amount for a mouse wheel event.

Returns:

wheel travel, or 0 if this is not a mouse wheel event
