OpenLayers. Control. ModifyFeature

Control to modify features. When activated, a click renders the vertices of a feature - these vertices can then be dragged. By default, the delete key will delete the vertex under the mouse. New features are added by dragging “virtual vertices” between vertices. Create a new control with the OpenLayers.Control.ModifyFeature constructor.

Properties

geometryTypes

{Array(String)} To restrict modification to a limited set of geometry types, send a list of strings corresponding to the geometry class names.

clickout

{Boolean} Unselect features when clicking outside any feature. Default is true.

toggle

{Boolean} Unselect a selected feature on click. Default is true.

standalone

{Boolean} Set to true to create a control without SelectFeature capabilities. Default is false. If standalone is true, to modify a feature, call the <selectFeature> method with the target feature. Note that you must call the <unselectFeature> method to finish feature modification in standalone mode (before starting to modify another feature).

deleteCodes

{Array(Integer)} Keycodes for deleting verticies. Set to null to disable vertex deltion by keypress. If non-null, keypresses with codes in this array will delete vertices under the mouse. Default is 46 and 68, the ‘delete’ and lowercase ‘d’ keys.

virtualStyle

{Object} A symbolizer to be used for virtual vertices.

mode

{Integer} Bitfields specifying the modification mode. Defaults to OpenLayers.Control.ModifyFeature.RESHAPE. To set the mode to a combination of options, use the | operator. or example, to allow the control to both resize and rotate features, use the following syntax

control.mode = OpenLayers.Control.ModifyFeature.RESIZE |
               OpenLayers.Control.ModifyFeature.ROTATE;

onModificationStart

{Function} Deprecated. Register for “beforefeaturemodified” instead. The “beforefeaturemodified” event is triggered on the layer before any modification begins.

Optional function to be called when a feature is selected to be modified. The function should expect to be called with a feature. This could be used for example to allow to lock the feature on server-side.

onModification

{Function} Deprecated. Register for “featuremodified” instead. The “featuremodified” event is triggered on the layer with each feature modification.

Optional function to be called when a feature has been modified. The function should expect to be called with a feature.

onModificationEnd

{Function} Deprecated. Register for “afterfeaturemodified” instead. The “afterfeaturemodified” event is triggered on the layer after a feature has been modified.

Optional function to be called when a feature is finished being modified. The function should expect to be called with a feature.

Constructor

OpenLayers. Control. ModifyFeature

Create a new modify feature control.

Parameters

layer	{OpenLayers.Layer.Vector} Layer that contains features that will be modified.
options	{Object} Optional object whose properties will be set on the control.

Functions

destroy

destroy: function()

Take care of things that are not handled in superclass.

activate

activate: function()

Activate the control.

Returns

{Boolean} Successfully activated the control.

deactivate

deactivate: function()

Deactivate the control.

Returns

{Boolean} Successfully deactivated the control.

Constants

RESHAPE

{Integer} Constant used to make the control work in reshape mode

RESIZE

{Integer} Constant used to make the control work in resize mode

ROTATE

{Integer} Constant used to make the control work in rotate mode

DRAG

{Integer} Constant used to make the control work in drag mode
