po.dblclick()

Constructs a double-click control with default settings. This control allows the user to double-click to zoom in on the given point, and shift-double-click to zoom out. The double-click snaps to the nearest integral zoom level, providing optimal display of tiles.

dblclick.map([x])

Adds this control to the specified map x, removes this control from its current map, or returns the current map. This method is typically not called directly, but is needed to support the map’s add method and remove methods.

If the argument x is specified, this method returns this. If x is null, this control is removed from its current map; otherwise, this control is added to the specified map. If no arguments are specified, this method returns the current map, which may be null. Whew!

dblclick.zoom([x])

Sets or gets the zoom mode of this control. If the argument x is specified, this method sets the zoom mode to the given named value and returns this. If no arguments are specified, this method returns the current named zoom mode.

The following zoom modes are supported: “mouse”, “center”. The default mode is “mouse”, which causes the control to zoom around the location at the mouse cursor. The “center” mode will zoom around the map center.
