A handler for mouse clicks. The intention of this handler is to give controls more flexibility with handling clicks. Browsers trigger click events twice for a double-click. In addition, the mousedown, mousemove, mouseup sequence fires a click event. With this handler, controls can decide whether to ignore clicks associated with a double click. By setting a pixelTolerance, controls can also ignore clicks that include a drag. Create a new instance with the OpenLayers.Handler.Click constructor.
| OpenLayers. Handler. Click | A handler for mouse clicks. |
| Properties | |
| delay | {Number} Number of milliseconds between clicks before the event is considered a double-click. |
| single | {Boolean} Handle single clicks. |
| double | {Boolean} Handle double-clicks. |
| pixelTolerance | {Number} Maximum number of pixels between mouseup and mousedown for an event to be considered a click. |
| stopSingle | {Boolean} Stop other listeners from being notified of clicks. |
| stopDouble | {Boolean} Stop other listeners from being notified of double-clicks. |
| Constructor | |
| OpenLayers. Handler. Click | Create a new click handler. |
| Functions | |
| deactivate | Deactivate the handler. |
{Boolean} Stop other listeners from being notified of double-clicks. Default is false. If true, any click listeners registered before this one will not be notified of any double-click events.
The one caveat with stopDouble is that given a map with two click handlers, one with stopDouble true and the other with stopSingle true, the stopSingle handler should be activated last to get uniform cross-browser performance. Since IE triggers one click with a dblclick and FF triggers two, if a stopSingle handler is activated first, all it gets in IE is a single click when the second handler stops propagation on the dblclick.
Create a new click handler.
| control | {OpenLayers.Control} The control that is making use of this handler. If a handler is being used without a control, the handler’s setMap method must be overridden to deal properly with the map. |
| callbacks | {Object} An object with keys corresponding to callbacks that will be called by the handler. The callbacks should expect to recieve a single argument, the click event. Callbacks for ‘click’ and ‘dblclick’ are supported. |
| options | {Object} Optional object whose properties will be set on the handler. |
Deactivate the handler.
