Hi. This is a GeoExt question, so I'd suggest taking the question to
the GeoExt users mailing list. You have more chance to get answers
there.

As a side note, do not set strategies into WMS layers, strategies

<http://www.openlayers.org/dev/examples/spherical-mercator.html>
open the firebug console, and do:
map.layers[0].setOpacity(0.2) // -> this changes the opacity of the
current base layer
map.layers[1].setOpacity(0.2) // -> this changes the opacity of the
Google Satellite layer, although it's not the current base layer
now select the Google Satellite layer in the LayerSwitcher, its
opacity is expectedly 0.2.
Maybe I don't understand the issue you're having.

No. I just opened

entered map.baseLayer.setOpacity(0.2) in the FireBug console and the
Google layer's opacity did change. Do you have a live example showing

map.baseLayer may be what you're looking for.

OpenLayers reads a GeoJSON FeatureCollection document into an array of feature (OpenLayers.Feature.Vector) objects, with each feature object having an "attributes" property containing the properties of the feature. So once you have this array of features you can do searches. If you have features in a vector layer the array of features is accessible at layer.features.

Looking at your code I feel you want to style each feature based on
the result of some operation on the feature attributes. If so I'd
recommend looking at the styles-context.html example, more
specifically at the way layer2 is styled in this example.

Your control is a button as opposed to a toggle, and it's not active by default its DOM element gets "Inactive" class. When you activate it gets the "Active" class, so it's rendering changes. I don't understand why you need two classes and two ways to render the button.

Yes, I think the format should behave gracefully on such cases. IIRC
with the patch I committed for WFS the format doesn't throw an
exception or ouput an error message, it just silently returns no
features. But I agree it may make sense to warn the caller by raising
an exception or something.

I'm suggesting creating a function that receives a layer, destroys the existing controls (if any), and creates new ones (configured with the passed layer). It's only 4 or 5 controls to destroy and create on each call to this function. Alternatively, you can add a setLayer method to the modify feature control. I'm not sure but the select feature control may have a setLayer method already, that would probably help you.

I think you can't dynamically change a modify feature control's layer.
For example, the select feature control the modify feature control
uses internally would also need to be reconfigured. So I'd recommend
creating new controls when switching from one layer to another.

to change a feature's state do feature.state = OpenLayers.State.INSERT
(or UPDATE or DELETE). If you use the modify feature control it'll
take care of modifying the feature's state.

I think you found a bug. The problem is, I think, unrelated to Control.Attribution, as the "terms of use" and "powered by" links/logos are handled in a specific way for Google layers. So I guess you create a ticket; if you attach a patch I'll review it.

Have you tried passing feature.attributes to the evaluate function?

I'm not familiar enough with GML to answer your question, sorry. I'd
just recommend that you ask the question again on dev@ if you don't
get answers here. Also, if you think this is a bug feel free to create
a ticket, and possibly attach a patch. See
<http://trac.openlayers.org/wiki/HowToContribute>. Thanks,

Hi. I don't know if that answers your question but you can use
OpenLayers.Util.extend in the "initialize" method to set the options
passed to the constructor in the instance:
initialize: function(options) {
OpenLayers.Util.extend(this, options);
}
You can then use this.Map from any method of the class.

the keys in your rType object must correspond to the values found in

(feature.attributes.rdlnstattx).

I'm not sure I get it. Why don't you do the whole thing once the layer
is loaded?
layer.events.on({
scope: layer,
loadend: function() {
// "this" references the layer
var features = this.features;
// do what you need with the features
// ...
}
});
the loadend listener need not be anonymous, you can also go with:
function onLoadend() {
var features = this.features;
}
layer.events.on({
scope: layer,
loadend: onLoadend // you don't call the function here but just
provide a reference to it
});
Hope this makes sense,

You may want to try to override the Map's updateSize method. You can
do that either by overriding the updateSize method in your map
instance:
var map = new OpenLayers.Map("div", {
updateSize: function() {
}
});
or by creating a custom Map class:
CustomMap = OpenLayers.Class(OpenLayers.Map, {
updateSize: function() {
}
});
I'd recommend you look at the Map.resizeMap method to understand what
it does first.

there's not. But you can inherit from LayerSwitcher and overload the
maximizeControl method:
CustomLayerSwitcher = OpenLayers.Class(OpenLayers.Control.LayerSwitcher, {
maximizeControl: function() {
OpenLayers.Control.LayerSwitcher.prototype.maximizeControl.apply(this,
arguments);
// do what you need here
}
});
note, though, that maximizeControl isn't part of the public API, so
this code could break with future OpenLayers releases.

The vector layer is configured with a WFS protocol, which is configured with a WFS format, which relies on a GML format for parsing geometries received in GetFeature responses.

loadURL is in the OpenLayers namespace. Although the section is named
"loadURL" in the documentation, the signature of the function provided
at the beginning of the section makes it clear that it's part of the
OpenLayers namespace.

Please explain. OpenLayers uses the current base layer's maxExtent as the max extent for the map. So your WMS layer must be a base layer for its maxExtent to be taken into account.

I don't get it. beforefeatureadded is triggered for every feature
added to the layer, it has nothing to do with the user selecting
features, hasn't it?

Hi look at the getfeature-wfs.html to know how to use the GetFeature control. And based on what you describe above I think what you want is a default filter set in the protocol, this default filter will be composed of mutiple FeatureId filters combined in an OR logical filter.

you can register a "beforefeatureadded" listener on the vector layer,
something like that:
layer.events.on({
beforefeatureadded: function(e) {
// only add features whose foo attribute
// is set to "bar"
return e.feature.attributes.foo == "bar" ?
true : false;
}
});

Yes, Google layers do not use the EPSG:4326 (lonl/at) coordinates
system. You can reproject lonlat, bounds and geometry objects to
EPSG:4326 using the transform method:
obj.transform(
new OpenLayers.Projection("EPSG:900913"),
new OpenLayers.Projection("EPSG:4326")
);
where obj is a LonLat, Bounds or Geometry object.

AFAIK you cannot register a browser event listener on a control's DOM
element using eventListeners (or control.events.register).
Have you tried
OpenLayers.Event.observe(control.element, "click", function(e) { ... });
?

use Layer.Vector with a Protocol.WFS, and the WFS GetFeature requests
will be sent using POST.

I modified the select-feature-openpopup.html so points with external
graphics can be drawn and selected (see attached patch). The example
works as expected in IE8. Can you modify the example yourself and
reproduce your problem?

implementing a specific control based on a Drag handler is what I'd go
with. You can look at the DragPan control to know how to use the Drag
handler - I tend to think that you could rely on the "move" and "done"
callbacks only. Now regarding the conflict with the Navigation
control: have you tried making sure your control is activated *before*
the Navigation control?

have you tried passing these resolutions to youe WMS layer, through
the "resolutions" config option. It should make OpenLayers "stop" the
layer when it's out of range.

Hi
it should work. I just did the following in the FireBug console:
>>> var cb = function() {}; scope = {};
>>> var e = new OpenLayers.Events({}, null, ["eventtype"]);
>>> e.register("eventtype", scope, cb);
>>> e.listeners["eventtype"].length == 1

You should use Layer.Vector, and configured your vector layers with a Protocol.WFS and a Strategy.Fixed.

the select feature control works with vector layers only. Anyway, it
is now recommended to use Layer.Vector for markers as well, through
the externalGraphic style property.
Sorry if I misunderstood your question.

MapFish web services aren't WFS web services. MapFish web services expose HTTP APIs based on GET (read features), POST (create features), PUT (update a feature) and DELETE (delete a feature). Now, as the application developer, you're free to implement WFS web services within your MapFish application if that's what you want, but using FeatureServer or GeoServer would prove lot easier.

Hi. I guess it depends on your needs. If FeatureServer just does the
job for you then I don't much benefit in switching to MapFish (except
maybe that we always make sure that client and server speak the same
language in MapFish). If you need to customize your web services then
use MapFish - MapFish is a framework for creating applications, an
application created with MapFish belongs to the developer, who is free
to modify his application and his application's web services to meet
his needs. It is also important to note that MapFish only supports
PostGIS as the data store at this time, support for MySQL and
Spatialite are in the plans.

Hi. This is a known issue. The RegularPolygon handler ignores

I'd recommend using a protocol. Something like this:
var protocol = new OpenLayers.Protocol.HTTP({
url: "url-to-geojson",
format: new OpenLayers.Format.GeoJSON()
});
protocol.read({
callback: function(response) {
if(response.success()) {
var features = response.features;
console.log(features);
} else {
console.log("failure");
}
}
});
Hope this helps,

there was an error in the doc, I just corrected it in trunk.

can't you just check layer.getVisibility() in the "click" callback?

You need to pass the GET function a callback:
OpenLayers.Request.GET({
url: "url",
params: {
get: "get"
},
success: function(request) {
alert(request.responseText);
}
});
Look at the API docs, you can also pass "failure" and "callbacks"
functions. You use the latter when you yourself want to determine
error conditions.

The cluster strategy will yield better display performace (fewer VML objects). However it will not speed up feature parsing - same number of objects in the response from the server. To me the cluster strategy helps more on the visualization side than on the performance side, but this is just a guess as I've never done any experiment actually showing it.

move "transparent" in the first object passed to the constructor (the
3rd argument), alongside the "layers" property. "transparent" is an
HTTP parameter of the layer, not an option.

Re: [OpenLayers-Users] Dynamically add vector layer from database

You basically have two options for serving vector data: either (a) use an external software such as GeoServer, MapServer or FeatureServer, or (b) implement it in your application. For the latter you can rely on existing librairies and/or frameworks. > One way is making an ajax request to my servlet and servlet > returns datas as json or xml format to my client side and adding this points > one by one to my vector layer, Yes. GeoJSON would yield good performance - parsing JSON is faster than XML in the browser. If you are to implement data serving within your java webapp and want to use GeoJSON as the data representation format I'd recommend looking at the MapFish GeoJSON Java library [*]. [*] <http://trac.mapfish.org/trac/mapfish/browser/trunk/MapFish/server/java/mapfish-geo-lib> > this is an inefficient way please show me the > possible way or ways. Sounds good to me. Client side you'd use an HTTP protocol (OpenLayers.Protocol.HTTP) with a format (ex : OpenLayers.Format.GeoJSON) in your vectoe layer.
