OpenLayers JavaScript Mapping Library | Index {Object} the code object issuing application events
{Object} A hashtable cache of the event observers. {OpenLayers.Pixel} distance in pixels to offset the image when being rendered Private. Ignore clicks, but allowing default browser handling Ignore double-clicks, but allowing default browser handling When mouse goes down within the popup, make a note of it locally, and then do not propagate the mousedown (but do so safely so that user can select text inside) If the drag was started within the popup, then do not propagate the mousemove (but do so safely so that user can select text inside) When mouse goes out of the popup set the flag to false so that if they let go and then drag back in, we won’t be confused. When mouse comes up within the popup, after going down in it, reset the flag, and then (once again) do not propagate the event, but do so safely so that user can select text inside {Boolean} Whether or not the feature is currently visible on screen (based on its ‘lonlat’ property) {Boolean} Whether or not the marker is currently visible on screen. {Boolean} Whether or not the marker is currently visible on screen. Catch the wheel event and handle it xbrowserly {float} The OpenLayers object provides a namespace for all things OpenLayers Basic types in OpenLayers are described here. Instances of this class represent bounding boxes. Contains functions to create OpenLayers style classes. The OpenLayers.Console namespace is used for debugging and error logging. Controls affect the display or behavior of the map. Imlements a very simple button control. Utility functions for event handling. Features are combinations of geography and attributes. Vector features use the OpenLayers.Geometry classes as geometry description. WFS handling class, for use as a featureClass on the WFS layer for handling ‘point’ WFS types. Base class for format reading/writing a variety of formats. Class for reading and writing Well-Known Text. A Geometry is a description of a geographic object. A Collection is exactly what it sounds like: A collection of different Geometries. A LineString is a Curve which, once two points have been added to it, can never be less than two points long. A MultiLineString is a geometry with multiple OpenLayers.Geometry.LineString components. MultiPoint is a collection of Points. MultiPolygon is a geometry with multiple OpenLayers.Geometry.Polygon components. Point geometry class. Polygon is a collection of Geometry.LinearRings. Base class to construct a higher-level handler for event sequences. Handler to respond to mouse events related to a drawn feature. Handler for wheel up/down events. Handler to draw a path on the map. Handler to draw a point on the map. Add GeoRSS Point features to your map. Instances of OpenLayers.Layer.Image are used to display data from a web accessible image as a map layer. Instances of OpenLayers.Layer.Vector are used to render vector data from a variety of sources. Instances of OpenLayers.Layer.WMS are used to display data from OGC Web Mapping Services. This class represents a longitude and latitude pair Instances of OpenLayers.Map are interactive maps embedded in a web page. Instances of OpenLayers.Marker are a combination of a OpenLayers.LonLat and an OpenLayers.Icon. This class represents a screen coordinate, in x and y coordinates Instances of this class represent a width/height pair This is a class designed to designate a single tile, however it is explicitly designed to do relatively little. Instances of OpenLayers.Tile.Image are used to manage the image tiles used by various layers. Instances of OpenLayers.Tile.WFS are used to manage the image tiles used by various layers. Get the opposite quadrant for a given quadrant string. {int} {OpenLayers.Geometry}This is set when a Geometry is added as component of another geometry Parse the data returned from the Events call. Create a new path hander Create a new OpenLayers.Pixel instance {OpenLayers.Feature.Vector} The currently drawn point Construct a point geometry. Create a new point handler. Constructor for a Polygon geometry. {OpenLayers.Popup} Create a popup. {Array(OpenLayers.Popup)} List of popups associated with the map {OpenLayers.Pixel} Top Left pixel of the tile When passed an xmlNode, parses it for a GML point, and passes back an object describing that point. {String} Set in the layer options to override the default projection string this layer - also set maxExtent, maxResolution, and units if appropriate. {String} Set in the map options to override the default projection string this map - also set maxExtent, maxResolution, and units if appropriate. {OpenLayers.Pixel} Change the index of the given layer by delta. Read data from a string, and return an object whose type depends on the subclass. Deserialize a WKT string and return an OpenLayers.Feature.Vector or an array of OpenLayers.Feature.Vector. clear all the marker div’s from the layer and then redraw all of them. Register an event on the events object. register an event on the map Registers events on the popup.
Remove all listeners for a given event type. Remove a component from this geometry. Only allows removal of a point if there are three or more points in the linestring. Remove components from this geometry. Removes a layer from the map by removing its visual element (the layer.div property), then removing it from the map’s internal list of layers, setting the layer’s map property to null.
{Boolean} Try to reproject this layer if its coordinate reference system is different than that of the base layer. Called on return from request succcess. {Array} {Number} |
