Re: [Gwt-openlayers-users] Any idea's about map.getControls() ?

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

Are you perhaps trying to get the controls when there are no controls
on the map? Or are you sure there are controls? I found the KMLTest to
fail when it did not return any vectorfeatures. Looking at that now.

Edwin

[Gwt-openlayers-users] Experience using OpenLayers 2.9?

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

Anyone tested using 2.9 yet? Are there anything broken or does it work
seamless? 
/Lukas

Re: [Gwt-openlayers-users] Any idea's about map.getControls() ?

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

Hi Andrew,

I am not sure what goes wrong, but apparently it happens in the
getPropertyAsArray method. I hope to be able to look at it tomorrow

The VectorFormat read method shows how an array can be retrieved
without the getPropertyAsArray method, so maybe that is an option.

Greetings,
Edwin

Re: [Gwt-openlayers-users] Any idea's about map.getControls() ?

[Andrew H. <ahh...@gm...>]

I tried the following (in Map):

/**
 * This will fetch all of the controls on the map.
 * @return the Controls or an empty array.
 */
public  Control[] getControls(){
JSObject[] jsObjects = getJSObject().getPropertyAsArray("controls");
int count = jsObjects.length;
Control[] controls = new Control[count];
for(int i =0; i < count ;i++){
controls[i] = Control.narrowToControl(jsObjects[i]);
}
return controls;
}

But this doesn't work, I'm out of my depth with JSNI...

java.lang.IllegalArgumentException: Something other than a Java object
was returned from JSNI method
'@org.gwtopenmaps.openlayers.client.util.JSObjectHelper::getProperty(Lorg/gwtopenmaps/openlayers/client/util/JSObject;Ljava/lang/String;)':

Any help would be greatly appreciated :)

Re: [Gwt-openlayers-users] Any idea's about map.getControls() ?

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

Hi Andrew,

That would be easy to add as a method to the Map, and it seems to make
sense. Controls are stored in an array on the map. We need to get the
JSObjects, narrow them to controls and return them in a Collection. I
guess there is no method for that in OpenLayers because accessing the
controls array is so easy in Javascript.

Greetings,
Edwin

[Gwt-openlayers-users] Any idea's about map.getControls() ?

[Andrew H. <ahh...@gm...>]

Hi Guys,

I need to be able to manipulate all the controls on a map, but I can't do
anything like... map.getControls(); any ideas?

Cheers

p.s. I really need to iterate over all controls and remove the ones I don't
want.

[Gwt-openlayers-users] OpenLayers MapWidget embedded in a SmartGWT canvas is not visible

[Chitra C. <ach...@gm...>]

Hi all,

Libraries I Am Using
---------------------------------
openlayers_gwt-0.4.jar
smartgwt.jar


Issue
---------
I have a smartGWT Portal with many smartGWT Portlets. These Portlets contain
smartGWT Canvasses. I am trying to add a MapWidget into a Portlet. The
following is my code:

public class MyWidget extends Canvas
{
    private MapWidget mapWidget;
    private Map map;
    private WMS wmsLayer;
    private Markers markers;
    private Popup popup;

    public MyWidget ()
    {
        // Create map widget and map objects
        mapWidget = new MapWidget("350px", "350px");
        map = mapWidget.getMap(); //instantiates map

        TMSOptions tmsOptions = new TMSOptions();
         tmsOptions.setFormat("image/png");
         tmsOptions.setDisplayOutsideMaxExtent(false);
         tmsOptions.setProjection("EPSG:4392");
         TMS tmsLayer = new TMS("OpenStreetMaps", "
http://tile.openstreetmap.org/", tmsOptions);
         map.addLayers(new Layer[] {tmsLayer});

        this.addChild(mapWidget);
        draw();
    }
}

This MyWidget canvas is added into the Portlet by calling:
portlet.addItem(new MyWidget());


When run, a map cannot be seen in my portlet. I can see the Portlet's <div>
element. However, there is no map element within the <div>. Does anyone know
why?


Replicating the above behaviour
----------------------------------------------
Adding the MapWidget directly onto the RootPanel still produced the same
behaviour as above - i.e. I can see the Portlet's <div> element but there is
no map element within the <div>. My code is as follows:

public void onModuleLoad()
    {
        DockPanel mainPanel = new DockPanel();
        mainPanel.setHeight("100%");
        mainPanel.setWidth("100%");

        // let's create map options
        MapOptions mapOptions = new MapOptions();
        mapOptions.setControls(new JObjectArray(new JSObject[] {}));
        mapOptions.setNumZoomLevels(16);
        mapOptions.setProjection("EPSG:4326");

        MapWidget mapWidget = new MapWidget("350px","350px", mapOptions);
         Map map = mapWidget.getMap();

        //Defining a WMSLayer and adding it to a Map
            WMSParams wmsParams = new WMSParams();
            wmsParams.setFormat("image/png");
            wmsParams.setLayers("basic");
            wmsParams.setStyles("");
            wmsParams.setMaxExtent(new Bounds(-74.047185, 40.679648,
-73.907005, 40.882078));


            WMS wmsLayer = new WMS(
                    "Basic WMS",
                    "http://labs.metacarta.com/wms/vmap0",
                    wmsParams);

            mapWidget.getMap().addLayers(new Layer[] {wmsLayer});

            mainPanel.add(new Label("hello"), DockPanel.EAST);
            mainPanel.add(mapWidget, DockPanel.CENTER);

            RootPanel.get("content").add(mainPanel);
    }


Any ideas anyone?

Thank you.

Kind regards,
Chitra

Re: [Gwt-openlayers-users] Event mapmoveend

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

Hi Lukas,

Thanks for contributing the patch. No additional stuff is needed for
providing the MapMoveEnd within GWT-OL. If the MapMoveEnd event object
has additional properties (beyond source) then getters can be created
on the MapMoveEndEvent inner class, but that is not a necessity and
doesn't seem to apply here.

I will get the patch in this week (hopefully tonight or otherwise thursday).

Greetings,
Edwin

Re: [Gwt-openlayers-users] Event mapmoveend

Ok, here it goes. I'm not 100% sure that the patch file was created correctly as my mercurial didn't honor the .hgignore file. I was therefore forced to edit the patch file to remove changes in .project and .classpath.

The patch is more or less just a copy of the existing moveEvent and I tested it in our application where it seems to work. Anything else I should do/know about?

Hi Lukas,

You seem to have it down. The classes you describe are all that are
needed and you can just look at the MapMoveListener.  Management of
the listener happens via de EventListenerCollection on
OpenLayersEObjectWrapper :).

A diff would be fine. Looking forward to your patch!

In the latest sourcecode the getWidth and setWidth methods of Size

About the BBOX issue I do not currently have any idea what could be going wrong.

Re: [Gwt-openlayers-users] Event mapmoveend

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

Hi Lukas,

You seem to have it down. The classes you describe are all that are
needed and you can just look at the MapMoveListener.  Management of
the listener happens via de EventListenerCollection on
OpenLayersEObjectWrapper :).

A diff would be fine. Looking forward to your patch!

Greetings,
Edwin

[Gwt-openlayers-users] Event mapmoveend

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

At http://dev.openlayers.org/docs/files/OpenLayers/Map-js.html it is
stated that three events exists concerting the movement of the map:

# movestart triggered after the start of a drag, pan, or zoom
# move triggered after each drag, pan, or zoom
# moveend triggered after a drag, pan, or zoom completes

As far as I understand only move has been wrapped in gwt-ol. If I were
to wrap moveend (the one I need) am I correct in believing that I only
need to:
* create a interface MapMoveEndListener 
* add eventType to EventType.java
* write a register method in Map.java

How do I send the changeset to you? A diff of the project?

Re: [Gwt-openlayers-users] Dynamic sizing of map

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

Hi all,

I had not looked well at the resize event. It appears it is only
thrown in FF for window resizes. In IE it does work for elements
(http://msdn.microsoft.com/en-us/library/ms536959%28VS.85%29.aspx).

Maybe there are workarounds like the YUI resize utility:
http://developer.yahoo.com/yui/resize/. However, I am not sure if this
actually provides the ability to monitor resizes of any element.

Within a specific GUI framework, such as Ext-GWT or SmartGWT the
panels will throw resize events and then the application developer
would be responible for listening to that event and calling
updateSize. However, it would be nice if it would work in native GWT.

Greetings,
Edwin

Re: [Gwt-openlayers-users] Dynamic sizing of map

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

Hi Andrew,

There may not be a native GWT resize event, but I looked up that there
is a resize event:

http://www.quirksmode.org/dom/events/resize.html

This event will be available via JavaScript and therefore can be
accessed in GWT with some work. Maybe it is possible to take a look
at:
http://api.jquery.com/resize/
(it is possible to wrap or port that)

This is something a JSNI lib could do (still want to pull of the JSNI
helper stuff out of GWT-OL and put it in a separate library)...

Greetings,
Edwin

Re: [Gwt-openlayers-users] Dynamic sizing of map

[Andrew H. <ahh...@gm...>]

There isn't a browser event for the resizing of an element... this is less
than ideal but it does work....

// update the map size every second (only way todo this)
Timer timer = new Timer() {
@Override
public void run() {
mapWidget.getMap().updateSize();
}
};
timer.scheduleRepeating(1000);


If anyone has a better idea, I would love to hear it.

Re: [Gwt-openlayers-users] Dynamic resize of Map

[Andrew H. <ahh...@gm...>]

This is really about css rules. I recommend you go take a look at <div>
based layout in css and how they differ from (the abusive and evil use of)
<table> based layout. Try and use div's, GWT 2.0's LayoutPanels were put
there for this reason :)

Then, when you run your app use firebug or chrome to peep at the html output
of your app... you might find some <tables> where you expect to see <div>
and you can also manually manipulate the css and html/elements at runtime to
test/debug on the fly in the browser.

Unfortunately these css problems are often a time sink, so be prepared.

[Gwt-openlayers-users] Markers in OpenStreetMap

[Hans T. M. <han...@ho...>]

Hi.

I'm having some difficulties with displaying markers when using the OSM 
class as the base layer.
When using a WMS layer it displays correctly, but when I change to OSM 
it don't get the coordinates
and are then displayed at the center of the map. Can someone explain this?

*Sample code from my project:*

public class Tutorial1 implements EntryPoint {

     private MapOptions mapOptions;
     private MapWidget mapWidget;
     private Map map;
     private OSM osmLayer;
     private Markers markers;
     private Marker marker;
     private LonLat center;
     private LonLat markerPosition;
     private Size size;
     private Icon icon;
     private DockPanel dockPanel;

     public void onModuleLoad() {
         mapOptions = new MapOptions();
         mapOptions.setControls(new JObjectArray(new JSObject[] {}));
         mapOptions.setProjection("EPSG:900913");
         mapOptions.setDisplayProjection(new Projection("EPSG:4326"));
         mapOptions.setMaxExtent(new
         Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34));
         mapOptions.setNumZoomLevels(19);
         mapOptions.setUnits("m");

         mapWidget = new MapWidget("1000px", "500px", mapOptions);
         map = mapWidget.getMap();
         map.addControl(new PanZoomBar());
         map.addControl(new MousePosition());
         map.addControl(new MouseToolbar());
         map.addControl(new LayerSwitcher());

         center = new LonLat(0, 0);
         map.setCenter(center, 3);

         osmLayer = OSM.Mapnik("OpenStreetMap");

         markers = new Markers("marker layer");

         map.addLayers(new Layer[] {osmLayer, markers});

         markerPosition = new LonLat(-73.99112, 40.77060);

         size = new Size(10,17);
         icon = new Icon("img/marker.png", size);
         marker = new Marker(markerPosition, icon);
         markers.addMarker(marker);

         dockPanel = new DockPanel();
         dockPanel.add(mapWidget, DockPanel.CENTER);
         dockPanel.setBorderWidth(1);
         RootPanel.get("map").add(dockPanel);
     }
}

Cheers,
Hans

Hi Hans,

Did you try the suggestions by Jon Britton? Appararently he got it
working with the latest snapshot (see gwt-ol website for link). I
found an older post by Carsten in the mailing list who got OSM working
as well and gave some example code.

The wrapper code is just a very thin, easy to understand layer (have a
look at some of the Layer classes), so if you know how it works in
Javascript it should be a small step to work out how it works in GWT,
or how it should work in GWT.

If I look at the OpenLayers code for a simple OSM map
(http://openlayers.org/dev/examples/) it should be as easy to add an
OSM layer to the map as:

layer = new OpenLayers.Layer.OSM( "Simple OSM Map");
map.addLayer(layer);

However, if I look at the OSM implementation in GWT-OL it is returning
an OSM layer like this:

return new $wnd.OpenLayers.Layer.OSM.Mapnik(name)

This is a constructor as it appears in
http://www.openstreetmap.org/openlayers/OpenStreetMap.js, which calls
the plain OSM constructor, but adds some extra (perhaps unwanted)
options. It is unclear to me at this point, when to use or when not to
use the 'OpenStreetMap.js' code. This dependency is not in any of the
current OpenLayers examples I could find on
http://openlayers.org/dev/examples/, and I always found it a bit murky
why OSM is hosting their own little library on top of OpenLayers
instead of contributing it to OL core.

The advanced OSM examples of OpenLayers are not even using OSM for the
rasters, but a WMS layer portraying OSM data. Possibly, this is
necessary to do the advanced features, but even if you just want the
OSM layers as background you could consider adding them as WMS layers
as in the Advanced OSM example.

If anybody knows what is the present best way to use OSM with
OpenLayers please let me know. I guess we do not want to break code
that already depends on the existing OSM, but we do want to get
up-to-date.

Greetings,
Edwin Commandeur

Re: [Gwt-openlayers-users] Question concernng Marker

[Brad K. <br...@gm...>]

The way I did this is probably not the best, but you can get the div
of the marker (parent in code below),and add a child element to put
the text in:

               DivElement datablock =
com.google.gwt.dom.client.Document.get().createDivElement();
               datablock.setClassName("matm-datablock");       // css style
               datablock.setId(uniqueID);
               datablock.setInnerText(this.toString());
               parent.appendChild(datablock);

The nice thing is then you can style it however you like.

[Gwt-openlayers-users] Problems with OpenStreetMap

[Ron Z. <rz...@gm...>]

Hello,

i extended the MapExample.initMapWidget to use OSM as follows:

		Markers markers = new Markers(""); 
		this.map.addLayer(markers);
		Layer osm = OSM.Mapnik("");
		osm.setIsBaseLayer(true);
		map.addLayer(osm);
		add(mapWidget, DockPanel.CENTER);
		markers.addMarker(new Marker(new LonLat(-122.3235810559386, 47.59126434612684)));

the marker is somewhere in Seattle USA.
On the WMS layer the marker is correctly displayed.
On the OSM layer it is displayed in Africa.

What am i doing wrong ???
