Re: [Gwt-openlayers-users] Handler Hover (Control), how?

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

Getting close but not yet, I think my native javascript is fundementally
flawed... says "OpenLayers is undefined".... perhaps I am missing some
$wnd.* somewhere :'( Any idea's? Sorry to bug people...

public class HoverControl extends Control {

    public interface HoverControlListener {
        void onPause(JSObject evt);
        void onMove(JSObject evt);

    protected HoverControl(JSObject element) {
        super(element);
    }

    public HoverControl(HoverControlListener listener) {
        this(HoverControlImpl.create(listener));
    }

    public static HoverControl narrowToHoverControl(JSObject element) {
        return (element == null) ? null: new HoverControl(element);
    }

    public static native JSObject create(HoverControl.HoverControlListener
callback) /*-{
        OpenLayers.Control.Hover = OpenLayers.Class(OpenLayers.Control, {

                defaultHandlerOptions: {

                    'stopMove': false
                },

                initialize: function(options) {
                    this.handlerOptions = OpenLayers.Util.extend(
                        {}, this.defaultHandlerOptions

Re: [Gwt-openlayers-users] Handler Hover (Control), how?

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

Hi Andrew,

The example you send works nicely, so I wonder what you are confused
about in native JavaScript. Seems a perfectly fine example of a custom
Handler.

A way to incorporate this handler in GWT-OL is by adding the code for
the Hover control in a javascript file and distribute that with GWT-OL
and wrap the native javascript like we wrap other Controls.

There are already some javascript utility functions which are in:
gwt-openlayers-client/src/main/java/org/gwtopenmaps/openlayers/public/js/gwt-openlayers/utils.js

Maybe we could put a ol-extensions.js file in there, and also make
clear in the GWT wrapper class namespace that it uses stuff in this
extensions file.

Another way would be to distribute the handler code with
GWT-OpenLayers and explain in the wrapper Javadoc that the js file
needs to be loaded in the page to use that specific wrapper class.

A combination of Javascript and GWT wrapper seems the way to go, since
I don't see a way to provide a Control in native GWT (you would always
need JSNI to add functions to the Control as fas as I can see).

Greetings,
Edwin

[Gwt-openlayers-users] Handler Hover (Control), how?

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

Hi Everyone,

We have a requirement that we need to register a hover handler on a map.
GWT-OpenLayers can't do this yet and the native javascript has me a little
confused... I have a simple javascript example working below. This seems
like it would be complex to wrap, advice would be most appreciated.

Re: [Gwt-openlayers-users] Projection supported?

[<tin...@ar...>]

Hey Jon,

you have to include your projection in your javascript. You can find the code for the proj4js-projection on http://spatialreference.org/ref/epsg/32630/proj4js/

Proj4js.defs["EPSG:32630"] = "+proj=utm +zone=30 +ellps=WGS84 +datum=WGS84 +units=m +no_defs";

I you don't do this the conversion returns the coordinates you have put in.
This should solve yout problem.

regarda

Tino

Re: [Gwt-openlayers-users] Projection supported?

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

I'm using 2.10.  I've solved that problem now, but my transformation still
isn't working.  I've included the proj4js.js library in my project, but the
result is always in EPSG:4326 (I'm trying to project to EPSG:32630).  I
assume the problem is that proj4js isn't finding the projection. I read
Proj4js user guide and it says that it will lookup the projection code on
spatialreference.org but this doesn't seem to be happening...

Does anybody know how to use proj4js with OpenLayers?  My GWT/JavaScript
method is below.

Cheers,

private static native JavaScriptObject reproject(double minX, double minY,
double maxX, double maxY, String source, String dest)/*-{
 var bounds = new $wnd.OpenLayers.Bounds(minX, minY, maxX, maxY);
var sourceProj = new $wnd.OpenLayers.Projection(source);
 var destProj = new $wnd.OpenLayers.Projection(dest);
bounds.transform(sourceProj, destProj);
 return bounds;
}-*/;

Re: [Gwt-openlayers-users] Projection supported?

[<tin...@ar...>]

Hey Jon,

the Openlayers.js contains the function transform in the class Openlayers.Bounds. It uses the Projection-class and it should be working. Which version do you use?

Re: [Gwt-openlayers-users] Projection supported?

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

What I really need is the transform method for the Bounds class.  I've been
trying to implement it in pure JavaScript but can't get it to work (it keeps
telling me my Bounds object doesn't have a "transform" function).

Re: [Gwt-openlayers-users] Projection supported?

[<tin...@ar...>]

Hi Jon,

the method transform isn't implemented yet. I have made it myself and it works. I have ask the admins of the openlayers-gwt-project for code-contribution, but to date I have no answer. I can send you the source-code if you like.

Tino

Is the Projection class supported in gwt-openlayers?  I can't seem to find
the transform methods.

Re: [Gwt-openlayers-users] containsPoint method of Polygon class

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

Hi Philipp,

Aha, so I did not understand containsPoint correctly. What we need is
three-valued logic, but there is no basic type for that :). One option
is to return a String and map the values onto that:

true = 'in'
false = 'out'
1 = 'edge'

That way the containsPoint implementation can just return a String.

public static native String containsPoint(JSObject p, JSObject self)/*-{
        var out = self.containsPoint(p);
        if (out === true) {return 'in'} // if out === 1 then if (out)
will also run!
        else if (out===1) {return 'edge'}
        else {return 'out'}
}-*/;

Greetings,
Edwin

Re: [Gwt-openlayers-users] containsPoint method of Polygon class

[Philipp V. <phi...@go...>]

Hi there,

thanks for that. But there is a problem:
your suggested code returns true if var is 1. But if var is true it returns
false...

The containsPoint()-method returns 1, if the point is on an edge.
It returns true, if the point is inside and it returns false, if the point
is outside.

With my not existing JS skills the solution was the following:

public static native boolean containsPoint(JSObject p, JSObject self)/*-{
       var out = self.containsPoint(p);
       if (out) {return true}
       else if (out===1) {return true}
       else {return false}
    }-*/;

Cheers and thanks,
Philipp

Re: [Gwt-openlayers-users] containsPoint method of Polygon class

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

Hi Phillip,

The containsPoint function in OL is a bit silly in that it returns 1
for true and false for false :). I would say we return a boolean.

Try adding this to Polygon

public boolean containsPoint(Point p){
    PolygonImpl.containsPoint(p.getJSObject(), this.getJSObject());
}

and this to PolygonImpl

public static native boolean containsPoint(JSObject p, JSObject self)/*-{
    var out = self.containsPoint(p);
    return (out===1)?true:false;
}-*/;

[Gwt-openlayers-users] containsPoint method of Polygon class

[Philipp V. <phi...@go...>]

Greetings,


I would like to use the containsPoint method of the Polygon class like it is
desribed:
http://dev.openlayers.org/docs/files/OpenLayers/Geometry/Polygon-js.html#OpenLayers.Geometry.Polygon.containsPoint

The method doesn't seem to be implemented in gwt-openlayers, am I right?!

Does anyone know a quick fix to use this method anyway?


Thanks and cheers,
Philipp

Re: [Gwt-openlayers-users] Popup CloseListener

Hi Marten,

Good to hear you solved the popup problem. I would definitely be
interested in that code :). I have never really used the popups that
come with OpenLayers (used Ext GWT windows instead), so I never looked
at closely how GWT-OL wraps them.

Re: [Gwt-openlayers-users] Popup CloseListener

[Mårten K. <mar...@di...>]

I solved this. All Popup-classes are implemented in a strange way, not
following the JavaScript-constructors of OpenLayers. What is the reason for
doing it like this? Anyway, I added constructors that take the CloseListener
and binds it to the closeBox at creation of the popups. That's the way
OpenLayers does it and that's the way I think openlayers-gwt should do it
too. I didn't remove the original openlayers-gwt constructors or the
addCloseListener-function in Popup for back compatibility issues.

Are you interested in this code?

[Gwt-openlayers-users] Popup CloseListener

[Mårten K. <mar...@di...>]

Hi!

I ran into problems when trying to adding a CloseListener to a FramedCloud.
The problem is similiar to what Christopher Navarro has described in a post
from february this year. The onPopupClose is caught as expected when using
the base class Popup (org.gwtopenmaps.openlayers.client.popup.Popup), but
doesn't work with FramedCloud
(org.gwtopenmaps.openlayers.client.popup.FramedCloud).

Chris, did you ever get this working? Does anybody else know something about
this problem?

I did some debugging using Firebug and it seems like one extra close box is
added when using FramedCloud. The extra close box conflicts with the
original close box as it has the same div id. They also listen to different
events and appearance. The first acts like default and closes the popup when
clicked but does not fire the onPopupClose event. Its position has changed
to upper left corner of the ???_GroupDiv. The extra close box is not visible
since it gets no z-index set, but it is hidden on the original position of
the first close box, i.e. the upper left corner of "the cloud". This close
box fires the onPopupClose event but does not close the popup.

Any suggestions?

Regards

Mårten Karlberg

[Gwt-openlayers-users] GWT-OpenLayers 0.5 Released

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

Greetings,

Around Twelve months in the making and GWT-OpenLayers 0.5 has been released,
a BIG THANK YOU to everyone who contributed. I've posted this across a few
mailing lists that might find this interesting blend of technologies
applicable to their needs, these are primarily the GeoServer, GWT, GWT-Maven
and OpenLayers.

Summary:

   - Substantial increase in the number of OpenLayers features exposed.
   - Many bug fixes and improvements.
   - Maven support, 0.5 has been released to maven's central repo (
   http://repo1.maven.org/maven2/org/gwtopenmaps/openlayers/gwt-openlayers/)
   - Increased documentation (http://gwt-openlayers.sourceforge.net/ including
   javadocs
   http://gwt-openlayers.sourceforge.net/maven-site-latest/gwt-openlayers-client/apidocs/index.html
   )
   - The project configuration is now entirely driven from maven
   (gwt-maven).

Some Big Thank You's for the people behind...

...Sonatype (http://www.sonatype.com/) for their support and fantastic
services/infrastructure. I can't recommend these guys enough - talk about
bringing large scale disciplined engineering to small scale projects :) Well
done.

...OpenLayers (http://openlayers.org/) for creating such a fantastic library
that we were able to wrap in GWT.

...GWT-Maven (http://mojo.codehaus.org/gwt-maven-plugin/), great plugin.

...and of course those behind GWT development!

For more information, please take a look at the latest documentation

Re: [Gwt-openlayers-users] VB: Producing clickable layers from WMS

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

Hi Lukas,

I will try to take a look at your patch today. Thanks for sending it
for review.

GWT-OL 0.5 has been pushed to the central maven repo two days ago and
I am working on the website generated by Maven to add some cookbook
recipes. Working with arrays is high on my list :).

Greetings,
Edwin

Re: [Gwt-openlayers-users] WMSGetFeatureInfo and AnchoredBubble

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

Sorry, of course my example didn't work (I read yours to fast and assumed that xy was a location stored in latlon).

1. Create a method GetFeatureInfoEvent.getXY()
2. Make sure that getLonLatFromPixel is wrapped in gwt-ol.

public void onGetFeatureInfo(GetFeatureInfoEvent event) {
       FrameCloud popup = new FramedCloud("MapFeaturePopup", Map.getLonLatFromPixel(event.getXY()), new Size(300, 400), html);
}

But I still think that this is cuite cumbersome.

Ämne: Re: [Gwt-openlayers-users] WMSGetFeatureInfo and AnchoredBubble

Yes, ok that will give you the coord that was clicked (not returned from the server). However if you would like to control how the data returned from the server should be displayed you'll need to parse the html or request it in GML as I stated earlier. In my case we have client side settings that determines what attributes that should be displayed in the popup and thus we read the data in GML and just displays the attributes according to this settings.

_If_ the event contains the xy property (as it seems to do according to your example) you could mimic your example by just adding a simple get method to GetFeatureInfoEvent (should there be such a method in gwt-ol? Whats the policy regarding private properties?). 
public void onGetFeatureInfo(GetFeatureInfoEvent event) {
       FrameCloud popup = new FramedCloud("MapFeaturePopup", event.getXY(), new Size(300, 400), html);
}
Remember though that this way of doing it is restricted to this kind of simple use cases.

Also note that I haven't tried it as I am currently on a train but I guess it should work.
Cheers

  In JavaScript I do it as follows:
this.popup = new OpenLayers.Popup.FramedCloud(
      "select_projects_popup",
      this.map.getLonLatFromPixel(event.xy),
      new OpenLayers.Size(250, 100),

It would be nice if we can get property "xy" from the event.

[Gwt-openlayers-users] VB: Producing clickable layers from WMS

Hi Lukas,

Thanks for the patch! The way you are handling arrays seems fine. In
GWT 2 the options for working with arrays expanded, but the wrappers
are still relevant IMHO, and working well. This is an area that could
definitively use some documentation.

I see you are also using getPropertyAsArray(). This is a method I
still need to look at, because it can run into nasty runtime errors
that have to do with casting from JavascriptObject to Java Object. The
method seems useful, so I guess it needs to be reimplemented to guard
it against runtime exceptions.

Greetings,
Edwin

[Gwt-openlayers-users] VB: Producing clickable layers from WMS

Hello Edwin
I just completed my implementation with clickable wmslayers trough WmsGetFeatureInfo. I found that there exists a way to request the data in a machine friendly way (GML) by setting infoFormat to "application/vnd.ogc.gml". This means that I get VectorFeatures straight from the request and therefore can reuse my exists WFS popuprenderers to render popups. No need for HTML templating :)

While working with the implementation I added setDrilldown, setLayers and setUrls to WmsGetFeatureInfoOptions as well as getFeatures in the GetFeatureInfoListener class. These changes allow me to decide exactly what layers to query and they don't have to be served by the same server, which is the case when using using drilldown. 

I'm quite sure that drilldown and setLayers where added in OL 2.9, but I hope it's ok that I wrapped them as well.

I'd like some feedback on the methods handling arrays (setLayers and getFeatures) as this is my first time using wrapped arrays in gwt-ol. Is this the way to do it or are there any better patterns?

/Lukas

Thanx I've totally missed that. I believed that I could request the data in a machine friendly format (for e.g. json). But it must be possible to create a template which will be easier to parse in my app code.

Thank you!

Hi Lukas,

In the code in trunk there is a WMSGetFeatureInfo example, similar to the example you reference. It uses a simple proxy included in the latest GWT-OL from trunk.

With WMSGetFeatureInfo you have to be aware that there is no standard for WMSGetFeatureInfo output. In GeoServer you can define templates for this output, see here:
http://geoserver.org/display/GEOSDOC/GetFeatureInfo+templates

It would be great if you want to contribute enhancements back to GWT-OL.

Greetings,
Edwin

Re: [Gwt-openlayers-users] WMSGetFeatureInfo and AnchoredBubble

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

I implemented these and sent a patch 2010-07-15 to Edwin Commandeur and cc to the list so that it would be included. Strange if it hasn't
In the mail where also some information about request format.
I send it to the list again.

  Also, if I get the data back as HTML will I still have a collection of 
features from which I can get the LonLat? Thanks, David
