[OpenLayers-Users] about Navigation and Box Control

[shane_china]

Use ZoomBox control is so easy, just like the common control.

var ctl = new OpenLayers.Control.ZoomBox();
map.addControl(ctl);

Please notice that, there are controls who exclude each other, navigation
and zoombox are one of the example. So you should to use Button group for
just active one of these exclusive controls.
That means active navigation, deactive zoombox, active zoombox deactive
navigation.

If you are new openlayers user and want more help, you can add my QQ
642106069, be fine.
