Are you using the newest GWT-OL?
Notice, that according to changelog addCloseListener is depreciated and 
not working correctly:
http://gwt-openlayers.hg.sourceforge.net/hgweb/gwt-openlayers/gwt-openlayers/

I never used it so far so not sure if its related to your problem.

[Gwt-openlayers-users] Popup addCloseListener() [SEC=UNCLASSIFIED]

[Towers, V. <Van...@ds...>]

UNCLASSIFIED

Hi,
 
I am having difficulty adding some extra functionality to a popup
closebox callback.
 
I have tried a couple of approaches. Currently I am Creating the popup
passing in the boolean "closebox" set to false in the constructor. Then
I try and add my own CloseListener Eg.
 
 popup.addCloseListener(new CloseListener() {
                                public void onPopupClose(JSObject evt)
                                {
                                    // my own implementation
                                }
                            });
 
But this isn't working as I would have expected. The onPopupClose method
is being hit when I can click the close button and doing the job. But
the close button is being positioned oddly. Sometimes it is positioned
outside of my framed cloud (but is clickable/closable), othertimes it is
in the right spot (top right corner of the cloud) but doesn't always let
me click it because it looks like my html text that is in the popup is
on top of it.
 
Any ideas what is going on?
 
Cheers,
 
Vanessa

Re: [Gwt-openlayers-users] WFS layers with GWT-OpenLayers

[Jon B. <jon...@go...>]

Hi Alex,

Thanks for the response, that seems to work! Just out of curiosity, is there
a way of displaying a WFS layer without specifying its namespace - with just
a url and a layer name?

Thanks,

Jon

Re: [Gwt-openlayers-users] WFS layers with GWT-OpenLayers

[Alexandre A. S. <aas...@gm...>]

You're missing a CallBack object to populate all the features retrieved from geoserver in the layer and a proxy to get data from the server in Javascript.
Have a look to my code, it works for me.

		    OpenLayers.setProxyHost("gwtOpenLayersProxy?targetURL=");
		    
		   VectorOptions vectorOptions =  new VectorOptions();
		   Vector eventsLayer = new Vector("Events", vectorOptions);		    		
			
		    WFSProtocolOptions wfsProtocolOptions = new WFSProtocolOptions("http://your-host/geoserver/ows","your-namespace", "your-wfs-layer");		   	
		    wfsProtocolOptions.setGeometryName(your-geometry-field);
		    wfsProtocolOptions.setSrsName("EPSG:4326");
		    wfsProtocolOptions.setVersion("1.1.0");
		    		   
		    
		    WFSProtocol wfsProtocol = new WFSProtocol(wfsProtocolOptions);
		   // WFS Protocol is asynchronous, so we need to use a callback
		    Callback callback = new Callback() {
			    public void computeResponse(Response response) {
			    	try
			    	{			    								
				    	VectorFeature[] features = response.getFeatures();
				    	for ( VectorFeature feature : features ) {
							//Apply style depending on any attribute of you feature
                                                        Style style = new Style();													
							style.setPointRadius(5);
							style.setFillColor("#00FF00");				
							feature.setStyle(style);
						}
				    	eventsLayer.addFeatures(features);						    	
				    	
			    	}
			    	catch (Exception ex)
			    	{
			    		//ERROR
			    	}
				}
			};			
			WFSProtocolCRUDOptions options = new WFSProtocolCRUDOptions(callback);			
			wfsProtocol.read(options);	    	

 
Hope it helps,

Hi,

I'm trying to add a WFS layer to my map but it's not displaying. Here is my code:


WFSProtocolOptions  wfsProtocolOptions = new WFSProtocolOptions();
wfsProtocolOptions.setUrl(featureType.getServiceUrl());
wfsProtocolOptions.setFeatureType(featureType.getName());
WFSProtocol wfsProtocol = new WFSProtocol(wfsProtocolOptions);
VectorOptions vectorOptions =  new VectorOptions();
vectorOptions.setProtocol(wfsProtocol);
vectorOptions.setStrategies(new Strategy[]{new BBoxStrategy()});

mapLayer = new Vector(featureType.getName(), vectorOptions);

SmartWPS.getSmartWPS().getMap().addLayer(mapLayer);


Where the url is "http://li199-25.members.linode.com:8080/geoserver/wfs" and the layer name is "topp:tasmania_roads".  I got this code from the showcase so I assumed it was all I needed.

Am I missing something? BTW the WFS is public if anybody wants to try it out :-)

Thanks,

Jon

[Gwt-openlayers-users] WFS layers with GWT-OpenLayers

Hi,

I'm trying to add a WFS layer to my map but it's not displaying. Here is my
code:


WFSProtocolOptions  wfsProtocolOptions = new WFSProtocolOptions();
wfsProtocolOptions.setUrl(featureType.getServiceUrl());
wfsProtocolOptions.setFeatureType(featureType.getName());
WFSProtocol wfsProtocol = new WFSProtocol(wfsProtocolOptions);
VectorOptions vectorOptions =  new VectorOptions();
vectorOptions.setProtocol(wfsProtocol);
vectorOptions.setStrategies(new Strategy[]{new BBoxStrategy()});

mapLayer = new Vector(featureType.getName(), vectorOptions);

SmartWPS.getSmartWPS().getMap().addLayer(mapLayer);


Where the url is "http://li199-25.members.linode.com:8080/geoserver/wfs" and
the layer name is "topp:tasmania_roads".  I got this code from the showcase
so I assumed it was all I needed.

Am I missing something? BTW the WFS is public if anybody wants to try it out

[Gwt-openlayers-users] Filtering WFS results

[Kjartan H. <kja...@gm...>]

Hello All

I'm new to gwt-openlayers and openlayers in general but I'm trying to filter
wfs queries based on their attributes. I've seen how this can be done in
openlayers with CQL filters but can't figure out how to implement this using
the gwt-openlayers plugin. Can anyone point me in the right direction
regarding this feature ?

Re: [Gwt-openlayers-users] How to calll javascript file in gwt

[Lukas J. <luk...@de...>]

Quick and dirty

·         Include the jsfile in MODULE.gwt.xml

·         Place the code that should be executed inside a method jsDoWhenClicked()

·         Create jsnimethod public native doWhenClicked() that calls the function jsDoWhenClicked in the javascriptfile

·         In clickhandler of the button call doWhenClicked()

Depending on the code you want executed you might instead translate it to Java or rewrite it into classes/methods to organize it better, but the above solutions does what you asked for.

Re: [Gwt-openlayers-users] Print overlayed maps in gwt-openlayers.

[Lukas J. <luk...@de...>]

Sure you could use the MapFish printer module to print the map and all its overlays (including vectordata). To get it to work you either need to load and wrap the Mapfish printprotocol (just one or two javascriptfiles needed) or write a "client"in gwt that sends the request to mapfish printerserver accourding to their restapi.

Bear in mind though that all mapfish code is GPL3.0 and therefore has copy-left. On the server this is not a problem as you could deploy it either as a standalone server or as a part of geoserver.
Using their js-files on the client side means that all your code must be released as GPL3.0

Another solution might be to create a printerfriendly view with openlayers and open this in a new window. This view could then be printed by the browser.

[Gwt-openlayers-users] ZoomOut and measure

[Alexandre A. S. <aas...@gm...>]

Hi,
I'm newbie in gwt-openlayers and I'm a bit confused in how to do some stuff, specially zoomOut and measures.
I saw several controls in the package org.gwtopenmaps.openlayers.client.control and most of them work great, but I spent some days trying to add measure and zoom out functionality without any success.

In measure tool I'm using Measure class, but in the constructor I'm required to pass Handler..... but, where can I take this handler? I know in OpenLayer you can get it from OpenLayers.GetHandler(), but what's about gwt-openlayers? Where can I get the handler?

About zoom out, I'm using ZoomOut class, with the next code:

                 if (controlZoomOut==null)
		{			
			controlZoomOut= new ZoomOut();
			map.addControl(controlZoomOut);	
		}		
		controlZoomOut.activate();

controlZoomOut id declared as private variable at the beginning of the class.

The thing is that my map doesn't enable zoomout functioanlity.... what am I missing?

Thank in advance,
Cheers,
Alexandre

The 0.6-SNAPSHOT on there has the functionality I need, anyway.

[Gwt-openlayers-users] Context menu

[Krishna R. A. <kri...@ym...>]

Hi All, 

I am using the Openlayers GWT MapWidget to show the map on my application. I 
have managed to get the WMS feature info upon clicking on the any feature in the 
map. Now I have another requirement which is to have a context menu on the 
MapWidget and have a Show Attributes option on it. 


I tried to extend the MapWidget and override the onBrowserEvent but it doesn't 
seem to be working. Is there any other way to add the context menu on the 
MapWidget?

Please advise.

Thank you,
K.

[Lukas J. <luk...@de...>]

<Forgot reply-all>

Ok, I added this functionality to gwt-ol and because of a misunderstanding between me and Edwin (I think it was) it did'nt make the 0.5 release. You'll need to build a version from source or get a version built by someone else.

For the moment the only version I have was built on July 15:th 2010 and includes the features you'll need for the WMSGetFeatureInfo but it lacks a lot of things that where made for the 0.5 release. I might have time to build another version from latest source within a couple of days but I can't promise anything.

I tried that already and didn't worked that way. I think there is a bug in the bindings!!!

info.getJSObject().setProperty("infoFormat", "application/vnd.ogc.gml");
does the magic for me and the format is set properly.

I have seen that the version 0.5 of openlayes is seting the infoformat as the following

    /**
     * defaults to 'text/html'
     */
    public void setInfoFormat(String infoFormat){
        getJSObject().setProperty("infoformat", infoFormat);
    }


it should be changed to the following

     */
    public void setInfoFormat(String infoFormat){
        getJSObject().setProperty("infoFormat", infoFormat);

Re: [Gwt-openlayers-users] WMS shifts to wrong location after zooming/panning

[Wigger T. <but...@ho...>]

Dear all,
Thank you for your help. unfortunately I haven't solved the problem yet. 
- My layout is the following: I have a dockpanel as root, and add an Absolute panel (containing the mapwidget) to the center of the Dockpanel.- I have tried both tiled and single tile layers. No real difference in result. Besides GWT I use smartgwt and incubator libraries. I used them before in other projects where they didn't seem to cause any problems. - In my map I dont believe other divs, like the selection element you mentioned, could cause the WMS div to move. 
Could it help if I send you the link to the application in a private email so you can see what happends? It seems that if I pan the WMS to the top left corner it fits again on the underground (OSM). 
Thanks again,Willem

I have found that problems like this crop up when the div that contains 
the map moves on the page.  My solution was to connect a function that 
re-centers the map to events that cause the location of the map div to 
move on the page.  In our case we add and remove some selection elements 
above the div pushing it up and down on the page and re-centering the 
map each time one of those elements was added/removed fixed the problem.

                 // Do a meaningless little calculation to force the map

                 int zoom = map.getZoom();
                 LonLat center = map.getCenter();
                 map.setCenter(center, zoom);

Re: [Gwt-openlayers-users] WMS shifts to wrong location after zooming/panning

[Edwin C. <com...@gm...>]

Are you using plain GWT or some GUI library?

It is OpenLayers that calculates these offsets for tiled layers.
Apparently it does this in way that does not play nice with GWT. Have
you tried untiled (get's the whole map image in one go, versus in
several tiles)? Or is that no option for you?

Greetings,
Edwin
