The DragFeature control moves a feature with a drag of the mouse. Create a new control with the OpenLayers.Control.DragFeature constructor.
| OpenLayers. | The DragFeature control moves a feature with a drag of the mouse. |
| Properties | |
| geometryTypes | {Array(String)} To restrict dragging to a limited set of geometry types, send a list of strings corresponding to the geometry class names. |
| onStart | {Function} Define this function if you want to know when a drag starts. |
| onDrag | {Function} Define this function if you want to know about each move of a feature. |
| onComplete | {Function} Define this function if you want to know when a feature is done dragging. |
| onEnter | {Function} Define this function if you want to know when the mouse goes over a feature and thereby makes this feature a candidate for dragging. |
| onLeave | {Function} Define this function if you want to know when the mouse goes out of the feature that was dragged. |
| documentDrag | {Boolean} If set to true, mouse dragging will continue even if the mouse cursor leaves the map viewport. |
| layer | {OpenLayers.Layer.Vector} |
| feature | {OpenLayers.Feature.Vector} |
| dragCallbacks | {Object} The functions that are sent to the drag handler for callback. |
| featureCallbacks | {Object} The functions that are sent to the feature handler for callback. |
| lastPixel | {OpenLayers.Pixel} |
| Constructor | |
| OpenLayers. | Create a new control to drag features. |
| Functions | |
| clickFeature | Called when the feature handler detects a click-in on a feature. |
| clickoutFeature | Called when the feature handler detects a click-out on a feature. |
| destroy | Take care of things that are not handled in superclass |
| activate | Activate the control and the feature handler. |
| deactivate | Deactivate the control and all handlers. |
| overFeature | Called when the feature handler detects a mouse-over on a feature. |
| downFeature | Called when the drag handler detects a mouse-down. |
| moveFeature | Called when the drag handler detects a mouse-move. |
| upFeature | Called when the drag handler detects a mouse-up. |
| doneDragging | Called when the drag handler is done dragging. |
| outFeature | Called when the feature handler detects a mouse-out on a feature. |
| cancel | Called when the drag handler detects a mouse-out (from the map viewport). |
| setMap | Set the map property for the control and all handlers. |
{Function} Define this function if you want to know when a drag starts. The function should expect to receive two arguments: the feature that is about to be dragged and the pixel location of the mouse.
| feature | {OpenLayers.Feature.Vector} The feature that is about to be dragged. |
| pixel | {OpenLayers.Pixel} The pixel location of the mouse. |
{Function} Define this function if you want to know about each move of a feature. The function should expect to receive two arguments: the feature that is being dragged and the pixel location of the mouse.
| feature | {OpenLayers.Feature.Vector} The feature that was dragged. |
| pixel | {OpenLayers.Pixel} The pixel location of the mouse. |
{Function} Define this function if you want to know when a feature is done dragging. The function should expect to receive two arguments: the feature that is being dragged and the pixel location of the mouse.
| feature | {OpenLayers.Feature.Vector} The feature that was dragged. |
| pixel | {OpenLayers.Pixel} The pixel location of the mouse. |
{Function} Define this function if you want to know when the mouse goes over a feature and thereby makes this feature a candidate for dragging.
| feature | {OpenLayers.Feature.Vector} The feature that is ready to be dragged. |
{Function} Define this function if you want to know when the mouse goes out of the feature that was dragged.
| feature | {OpenLayers.Feature.Vector} The feature that was dragged. |
Create a new control to drag features.
| layer | {OpenLayers.Layer.Vector} The layer containing features to be dragged. |
| options | {Object} Optional object whose properties will be set on the control. |
clickFeature: function( feature )
Called when the feature handler detects a click-in on a feature.
