undo: function()
Remove the most recently added point in the sketch geometry.
unfreezeFeature: function(row)
unhighlight: function(feature)
Redraw feature with the “default” style
{String} The layer map units.
{String} The map units.
unload: function()
Call immediately before destroying if you are listening to tile events, so that counters are properly handled if tile is still loading at destroy-time.
unloadCache: function()
Cycle through all the element entries in the events cache and call stopObservingElement on each.
Function that is called to destroy the map on page unload.
unregister: function(responderToRemove)
unregister: function (type,
unregister: function (name,
unregister an event from the map
Unregister a callback previously registered with the register function.
unregisterMouseListeners: function()
In a touch environment, we don’t want to handle mouse events.
{Object} hash of features, keyed by, that the renderer failed to draw
unselect: function(feature)
Remove feature from the hash of selected features and trigger the featureunselected event.
unselect: function(feature)
Remove feature from the layer’s selectedFeature array, render the feature as normal, and call the onUnselect function.
unselectAll: function()
Unselect all selected features.
unselectAll: function(options)
Unselect all selected features.
unselectFeature: function(feature)
Called when the select feature control unselects a feature.
unsetFeature: function()
Remove the transformation box off any feature.
{Array} Array with browsers, which should use the HTTP-GET protocol instead of HTTP-POST for fetching tiles from a WMS .
up: function(evt)
This method is called during the handling of the mouse up event.
{OpenLayers.Pixel} The location of the last mouseup.
up: function (evt)
Handle mouseup and touchend.
up: function (evt)
Handle mouseup and touchend.
up: function(evt)
Finish drawing the feature
update: function(xy)
Updates during the dragging.
update: function()
calculates the grid to be displayed and actually draws it
update: function()
Update the overview map after layers move.
update: function()
Update the size of the bars, and the labels they contain.
update: function(feature)
Takes a feature, and generates a WFS-T Transaction “Update”
update: function()
Construct a request updating modified features.
update: function(feature,
Construct a request updating modified feature.
update: function(features,
Construct a request updating modified feature.
update: function(options)
Callback function called on “moveend” or “refresh” layer events.
updateAttribution: function()
Update attribution string.
updateAttribution: function()
Updates the attribution according to the requirements outlined in
updateBlocks: function()
Internal method, called on initialize and when the popup’s relative position has changed.
updateContainerCenter: function()
Must be called each time the layer container moves.
updateDimensions: function(zoomChanged)
updateDimensions: function(zoomChanged)
updateGrid: function(force)
Update the grid.
updateHandler: function(handler,
updateLink: function()
updateMap: function()
Cycles through the loaded data and base layer input arrays and makes the necessary calls to the Map object such that that the map’s visual state corresponds to what the user has selected in the control.
updateMapToRect: function()
Updates the map extent to match the extent rectangle position and size
updateMatrixProperties: function()
Called when map resolution changes to update matrix related properties.
updatePosition: function()
if the popup has a lonlat and its map members set, then have it move itself to its proper position
updateRectToMap: function()
Updates the extent rectangle position and size to match the map extent
updateRelativePosition: function()
The popup has been moved to a new relative location, so we may want to make some cosmetic adjustments to it.
updateRelativePosition: function()
The popup has been moved to a new relative location, in which case we will want to re-do the rico corners.
updateRelativePosition: function()
When the relative position changes, we need to set the new padding BBOX on the popup, reposition the close div, and update the blocks.
updateScale: function()
updateSize: function()
This function should be called by any external code which dynamically changes the size of the map div (because mozilla wont let us catch the “onresize” for an element)
updateSize: function()
Auto size the popup so that it precisely fits its contents (as determined by this.contentDiv.innerHTML).
When the map is destroyed, we need to stop listening to updateSize events: this method stores the function we need to unregister in non-IE browsers.
{Boolean} true if update operations are done with POST requests defaults to false.
upFeature: function(pixel)
Called when the drag handler detects a mouse-up.
{Number} or {String} upper boundary for between comparisons.
