Re: [Gwt-openlayers-users] Wrapping XYZ Layer

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

Hi Andrew,

I wonder when the updateSize method should be called. As far as I know
it should work to let the OpenLayers div be 100% by 100% of the parent
div, since the size of the div is requested from the div when it is
needed. It seems that the updateSize method is a work-around for when
you set a fixed width and height, while in reality the map is not
fixed, but the parent div can be expanded and the div containing the
map should resize to its parent. However, maybe I am missing out on
something there.

If you have a good use case for the XYZ class then please add it to
Trac. You can create tickets without having to log in. It seems the
XYZ class is a low-level thing intended for use in specific OpenLayers
classes, such as the OSM layer. I see that it wrongly states above the
XYZ constructor that it is the OSM layer constructor. We should
possible wrap both the XYZ and the OSM layer, with the OSM layer
extending XYZ.

For OpenStreetMap things are a bit unclear to me, because there is
also the TMS layer, which is wrapped by GWT-OL by someone who used
OpenStreetMap. I am not sure which layer is more up to date XYZ/OSM or
TMS. It seems that one of them is obsolete. The 'osm-layer.html'
example in OpenLayers 2.8 includes OSM data by means of a WMS. The
'tms.html' does have a TMS layer, but is not what I expected to see.
Andrew, if you know more about this, please let me know.

Greetings,
Edwin

[Gwt-openlayers-users] Wrapping XYZ Layer

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

Hi Guys,

I have a few things I would like to add/wrap.

Map.updateSize()
http://dev.openlayers.org/releases/OpenLayers-2.8/doc/apidocs/files/OpenLayers/Map-js.html#OpenLayers.Map.updateSize

Layer.XYZ
http://dev.openlayers.org/releases/OpenLayers-2.8/doc/apidocs/files/OpenLayers/Layer/XYZ-js.html


How would you like me to proceed? Do we raise issues or what first e.t.c???

Cheers.

Thank you for your answer. I checked out the working copy and it worked.

Hi Lukas,

This issue happens on version 0.4 but was already fixed in the current source code (mercurial repository).

You can get the last source code from the mercurial repository: http://gwt-openlayers.hg.sourceforge.net:8000/hgroot/gwt-openlayers/gwt-openlayers.

I've noticed that the onFeatureUnselected receives a JSObject while the onFeatureSelected receives a VectorFeature which seams a bit odd. 

 

Any help would be appreciated.

[Gwt-openlayers-users] Problem using SelectFeature.

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

Hello, I'm trying to use SelectFeature in gwt-openlayers 0.4:

Layer layer = new Vector();

Control cntrl = new SelectFeature(layer);

 

SelectFeatureOptions options = new SelectFeatureOptions();

options.onSelect(new SelectFeatureListener() {                   

    public void onFeatureSelected(VectorFeature vectorFeature) {

        Window.alert("feature selected");

    }

});

                                                          

options.onUnSelect(new UnselectFeatureListener() {

    public void onFeatureUnselected(JSObject vectorFeature) {

        Window.alert("feature unselected");

    }

});

map.addControl(cntrl);

 

But when the code is executed I get the following error:

14:52:51.378 [WARN] [Standard] Member

I've noticed that the onFeatureUnselected receives a JSObject while the
onFeatureSelected receives a VectorFeature which seams a bit odd. 

 

Any help would be appreciated.

[Gwt-openlayers-users] Overview Map Options

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

Greetings,

I'm trying to use an overview map with a different maplayer than shown in
the map window. But I have problems integrating the overview map layer.
Here is some code:


        // Set up the WMS which extends Layer
        WMSParams wmsParams = new WMSParams();
        wmsParams.setFormat("image/png");
        wmsParams.setIsTransparent(true);
        wmsParams.setLayers("basic");
        wmsParams.setStyles("default");
        wmsParams.setMaxExtent(new Bounds(90, 0, 120, 20));

        WMSOptions wmsLayerParams = new WMSOptions();
        wmsLayerParams.setIsBaseLayer(false);
        wmsLayerParams.setLayerOpacity(1.0);

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

        OverviewMapOptions options = new OverviewMapOptions();
        Layer[] layers = new Layer[1];
        layers[0] = (Layer)wmsLayer;
        options.setLayers(layers);

        map.getMap().addControl(new OverviewMap(options));


Anyone knows whats wrong with the code?

[Gwt-openlayers-users] Getting absolute window size

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

Greetings,

I'm using a SmartGWT Window to display the openlayers map and the size can
be given in absolute px*px or relative in % or *.
Openlayers seems to need an absolute size to display the map. Am I right in
this point?
Is it possible to just load the map and fit it's size to the extent of the
SmartGwt Window?

Cheers,

[Gwt-openlayers-users] Using WMS

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

Greetings,

I'm new in devoloping with openlayers-gwt and I tried to use a different WMS
than the one that is used in the gwt-openlayers-showcase
(http://labs.metacarta.com/wms/vmap0...).
And I also tried to change the position of Map Controls (like NavToolBar,
MousePosition, PanZoom, ...).

So far, my effort was not very effective.

My goal is to use an openstreetmap layer (if possible to display the whole
world, if not at least asia) and to have the Map Controls in some sort of
toolbar at the top.

I would be thankful for anything, especially code snippets.

Cheers,
Philipp

Re: [Gwt-openlayers-users] Event Model

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

Hi David,

First of all thanks for your previous contributions. I hope to soon
have time to merge the user contributions into the main code base, but
for now I am swamped with work unfortunately.

It seems that you are mixing two questions in your question about the
events. One about how GWT-OL abstracts OL events and one about OL
events.

In GWT-OL there is a wrapper of the OL event at a basic level of
abstraction with the EventHandler, but this requires more knowledge of
the user of the GWT-OL API. Therefore, a layer of abstraction has been
build on top of the EventHandler that calls the EventHandler under the
hood. Therefore, the second, higher layer of abstraction of OL events,
builds on top of the basic abstraction and they are not two different
things.

GWT-OL events fired by controls and layers are specific for that
layer, so not global. It could be that protocol HTTP returns a
singleton and the effects are therefore global. I am not sure what you
mean when you say 'when my wrapper was active'. The higher layer of
abstraction of OL events also instrumented the registering and
unregistering of events, because the EventListenerCollection keeps the
information to do this. When a listener is unregistered that is
registered via the EventListenerCollection it should no longer receive
notifications of the event it was previously registered to.

There is another way of listening to callbacks by the way, which is
illustrated in org.gwtopenmaps.openlayers.client.control.SelectFeature.
This uses the possibility to call "Java" code from javascript in GWT.
This is useful if you are dealing with callbacks instead of events as
thrown by the OL event object.

Hope this is helpful for you.

Greetings,
Edwin

[Gwt-openlayers-users] Event Model

[David P. <dav...@pi...>]

Hi

I trying to understand the event model used in gwt-openlayers

As far as I understand it, there are two event models.

The one based on openlayers register event, etc.

The the model employed in gwt-openlayers, eg addMapClickListener from
Map.java.

They are both based on the same code model, but I have an issue with the
openlayers one.

I have written a wrapper for the OpenLayers.Protocol.HTTP function.  Its
it provides several callback interfaces.  In my wrapped version I support
both the use of the callback paramter and an addProtocol style function.

As I expected when ever I accessed a file the callback function for the
success event fired.

BUT my callback function installed by the gwt-openlayers function fired
whenever a file protocol event fired, ie when ever openlayer opens a file
my protocol specfic callback function was called, instead of only being
called when my protocol wrapper was active.

It seems that anycallback function installed by an openlayers Listener
function are global,ie  not tied to a specfic instance off an object.  Is
this the expect results or should objects only get events that they
created?

The only reason thatI ask is that I want to wrap some of the
Handler(Hover,Box, MouseWheel, etc)  objects which have an extensive
system off callbacks functions and I want to get the right interface.

HI Edwin, Roland

Thanks for this I will have a play with Mercurial

Instead of dumping the svn, is it possible to get the source forge setup 
just to say we don't use svn, just the following to get a copy of the

file that says how to get the source code?

Hi Dave,

Roland is correct, the code is in Mercurial. The SVN repository is
only there to make Trac happy (an SF issue). However, it has confused
so many people already that I am thinking about removing the SVN repo
and putting up with a red error bar in Trac.

Edwin

Re: [Gwt-openlayers-users] Zoom proportional point radius and handling both hover and click events at the same time

[Mikael C. <mik...@cl...>]

Hi again,


I've taken it a step further :

1) Point radius proportional to the zoom
After a few tests trying to delegate the functionnality to OpenLayers, I
gave up. The whole thing was gonna end up in really bad design (with Style
instances holding a reference to the Map instance).
I'll just implement the whole thing with a zoom listener.
By doing this, I run into a new feature I'd like to add to GWT-OpenLayers
(being able to define the point radius as a string). I'll create the Trac
ticket.

2) Handling both hover events and click events at the same time for vector
features
In fact it was very easy, I'll create the Trac ticket.

[Gwt-openlayers-users] Zoom proportional point radius and handling both hover and click events at the same time

[Mikael C. <mik...@cl...>]

Hello,


I am working on a project involving GWT-OpenLayers, the project is in its
early phase and I'm currently building a prototype.
I'm using the 0.5 version because I need MapStyles.

I have encountered technical limitations implementing two features, and I
felt I could use your advice :

1) Point radius proportional to the zoom
Here's an example of what I'd like to have :
http://www.palewire.com/openlayers-proportional-symbols/
I guess I could use the zoom listener to implement this behaviour, but it
doesn't seem right. I'd rather delegate this task to OpenLayers. However, I
don't even know if it's possible (Did I mention I'm not very good in
JavaScript and JSNI ?).
I'd be happy to contribute to the project, but I woudn't like to start
anything before asking you guys if it's a good idea.
Maybe I can be more specific in my questions :
 - Is it possible to implement such a behaviour in GWT-OpenLayers without
breaking the design ?
 - How long would it take for a noob to master the art of JSNI enough to do
such a thing ?
 - Where would you start ?

2) Handling both hover events and click events at the same time for vector
features
>From my various tests, I concluded that the only way to trigger a feature
related event is through the SelectFeatureListener. It works great, but in
my case I want to trigger one event when the feature is hovered, and a
second when it is clicked. However, it is not possible because when it is
clicked it has already been selected by the hover.
>From what I've seen from the code and the OpenLayers API, it shouldn't be

I think I could do it, but if you guys think you can get it done quickly you
might want to consider the option.
What do you say, should I create a Trac ticket and get to it ?

By the way, thanks for the great tool, i'm sure lots of people like me have
found it useful.

[Gwt-openlayers-users] Refresh size of openlayers map

[Thierry T. <te...@ya...>]

Hello,

I try to update the size of a map according to the size of its resizable container. I handle the resize event of the container and try to notify map and its layers to be also resized but it seems not to work.
My maps come from geoserver and are displayed using GWT and GWT-Ext...

Here is my code:

mapWidget.setSize(panel.getWidth()+"px", panel.getHeight()+"px");
//mapWidget.getMap().updateSize();
Layer[] layers = mapWidget.getMap().getLayers();
for (Layer layer : layers) {
    JSObject props = layer.getJSObject();
    props.setProperty("width", panel.getWidth());
    props.setProperty("height", panel.getHeight());
    layer.redraw(true);
}
panel.doLayout(false);

Is my code correct or/and is there another way to do?
Moreover I'm astonished not to find the updateSize on the map object. This one seems to implement this feature...

Thanks very much for your answer and your great tool!!
Thierry

Thanks very much for sending along the code to implement these
features.  A similar solution (and a number of other newly implemented
features like the RegularPolygonHandler which are not in the currently
released jar) are in the current head of the source code repository.<br>

We should probably create a new jar, but in the meantime you might find
building from source fills in some holes in the current distribution.<br>

I was a bit hasty and added some issues to the SF issue tracker. I'll 
add the same issues to Trac.

For now I added the patches to the tickets in Trac. I'm fairly sure I 
will keep fixing things/adding features that I need. If there's no 
development process, I think I'd rather contribute tickets+patches than 
have commit access, though. Access to the developer mailing list would 
be nice, though.

Re: [Gwt-openlayers-users] openlayers-gwt question

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

Hi Andrew,

If you want to make a custom control into a reusable control, I would
create a javascript file saying

My.Namespacing.Object.ShiftClickDrag = OpenLayers.Util.extend( ... see
example ...);

And then wrap the ShiftClickDrag in a way similar to any other Control
is wrapped in GWT-OL, but in a separate GWT-OL-Extension lib. For the
latter I can only recommend to look at the code in the Mercurial
repository.

Edwin

Re: [Gwt-openlayers-users] Vector + StyledMap example

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

Hi Ricky,

There is a GWT-OL example in the showcase in the Mercurial trunk.
StyleMap support is a recent addition to GWT-OL, that is not yet in
GWT-OL 0.4.

Greetings and good luck,
Edwin
