Properties

type

{ALKMaps.Control.TYPES}

panned

{Boolean} The map moved.

interval

{Integer} The number of milliseconds that should elapse before panning the map again. Defaults to 1 millisecond. In most cases you won’t want to change this value. For slow machines/devices larger values can be tried out.

documentDrag

{Boolean} If set to true, mouse dragging will continue even if the mouse cursor leaves the map viewport. Default is false.

kinetic

{<ALKMaps.Kinetic>} The ALKMaps.Kinetic object.

enableKinetic

{Boolean} Set this option to enable “kinetic dragging”. Can be set to true or to an object. If set to an object this object will be passed to the {<ALKMaps.Kinetic>} constructor. Defaults to false.

kineticInterval

{Integer} Interval in milliseconds between 2 steps in the “kinetic scrolling”. Applies only if enableKinetic is set. Defaults to 10 milliseconds.

Functions

draw

draw: function()

Creates a Drag handler, using panMap and panMapDone as callbacks.

panMapStart

panMapStart: function()

panMap

panMap: function( xy )

Parameters

xy	{ALKMaps.Pixel} Pixel of the mouse position

panMapDone

panMapDone: function( xy )

Finish the panning operation. Only call setCenter (through panMap) if the map has actually been moved.

Parameters

xy	{ALKMaps.Pixel} Pixel of the mouse position
