- * Specific properties for controls on a panel:

- * If not provided, <OpenLayers.Control.TYPE_TOOL> is assumed.

- *
- * The <OpenLayers.Control.type> of a control determines the behavior when
- * clicking its icon:
- * <OpenLayers.Control.TYPE_TOOL> - The control is activated and other
- * controls of this type in the same panel are deactivated. This is
- * the default type.
- * <OpenLayers.Control.TYPE_TOGGLE> - The active state of the control is
- * toggled.
- * <OpenLayers.Control.TYPE_BUTTON> - The
- * <OpenLayers.Control.Button.trigger> method of the control is called,
- * but its active state is not changed.
- *
- * If a control is <OpenLayers.Control.active>, it will be drawn with the
- * olControl[Name]ItemActive class, otherwise with the
- * olControl[Name]ItemInactive class.
- *
- * Parameters:
- * options - {Object} An optional object whose properties will be used
- * to extend the control.
