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

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

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

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

Hi Chris,

For now, I'd prefer if you send me the code as a patch created from
mercurial (unified diff) so I can review it and merge it in trunk.

If you keep working on GWT-OL and have more patches then I can add you
as a developer.

Greetings,
Edwin

[Gwt-openlayers-users] contributing code

[Christian T. <chr...@gm...>]

Hi all,

While playing with the GWT-OL I've implemented some methods and classes
still missing in GWT-OL. For instance the 'trasform' and the
'intersectsBounds' methods in the Bounds class or the basic implementation
for the HttpProtocol (e.g. OpenLayers.Protocol.HTTP).

Is there a mechanism I can contribute this (and future) code back to the
project?

Cheers,
Chris

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

Hi Giuseppe,

Sounds great. Does that mean GWT-OL is used within GeoSDI?

I would be glad to add you as developers to the project.

Do you have SourceForge accounts? I need the SF usernames to grant you
developer access :).

Hi all,
First, great job. My colleague(Francesco Izzi) and I have implemented the
part for the management of GML and I personally have added something to
WMSGetFeatureInfo for managing cached Layers. I prepared a  Maven project
with GWT-OL and the possibility to start the application with mvn jetty:
run.
Francesco and I work at the CNR IMAA and we develop for Civil Protection
Dept. and we ask the opportunity to commit the code that we wrote and join
the development team to add more features to the project.

Re: [Gwt-openlayers-users] OpenLayers.Control.Button [SEC=UNCLASSIFIED]

[Couzic M. <mik...@gm...>]

Hi Vanessa,

If you feel like you should use OpenLayers.Control.Button, then just
implement it in GWT-OpenLayers !
That's how I became a contributor, I needed some functionnality that wasn't
implemented, so I just did it myself. It's not that hard, and you can always
ask for help if you need.
I have 2 advices to help you start :
 - develop a working example using OpenLayers in JavaScript. It will help
you get a grasp of the API. It doesn't have to be complicated, just do
something like this :
http://funmap.co.uk/openlayers-test/buttons.html
 - study an existing class of GWT-OL. Choose one that is as similar as
possible to the one you want to implement.

Please do not hesitate to ask for help if needed.

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

Hi Brad,
 
I am also using Ext GWT for my UI widgets and I agree the toolbar would
be an alternative. In fact I am doing something similar currently. It's
not exactly what I am after as I think it looks a little strange having
a set of default buttons on the map already (such as the editing
toolbar, hand tool, zoombox - which are tied to the map) then another
set in an external toolbar (which also have functionality tied to the
map). But it seems it might be the only sensible option at this point.
Maybe it would be easier to move everything to an Ext GWT toolbar so
they are all in the same place?
 
Thanks,

Hello, I was just wondering if this really has to be part of the map
panel.

I've been using Ext GWT for UI widgets, and they have a nice toolbar.
You could place it just above the map panel in an overall container
panel or layout.

[Gwt-openlayers-users] OpenLayers.Control.Button [SEC=UNCLASSIFIED]

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

Hi,
 
I noticed OpenLayers.Control.Button is yet to be supported in the
gwt-openlayers project. I'm currently working with the latest snapshot
openlayers_gwt-0.5-SNAPSHOT.jar.
 
I really need to be able to put simple buttons in a custom toolbar
within the map panel. It's not something I've done in openlayers
previously. From what I can see this could be implemented using
OpenLayers.Control.Button if it was supported. I was wondering if this
was something I could easily implement myself and if so what would be
involved if someone could provide some guidance?

Re: [Gwt-openlayers-users] GWT-OpenLayers and SmartGWT

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

Hi again,

I've solved my error problem, now I've discovered that my map is there...
but it has a height of 0px.  I've tried the suggestions here but for some
reason I always get the same result.  Here is my code:

VLayout mapLayout = new VLayout();
mapLayout.setWidth100();
mapLayout.setHeight100();
mapLayout.setBackgroundColor("#FFFF99");
 mapWidget = createMap();
HLayout mapPanel = new HLayout();
mapPanel.setWidth100();
mapPanel.setHeight100();
mapPanel.addChild(mapWidget);
mapLayout.addMember(mapPanel);

I'm at a loss as to how I should fix this... any help would be appreciated!

Thanks,

Jon

Hi Lukas,

Thanks for the feedback on your own question. Great to hear that
upgrading worked smoothly.

Answering my own question. I upgraded to 2.9.1 in our application which uses multiple baselayers, multiple WFSlayers, editing trough WFS and a whole lot other things. I haven't yet found anything that got broken other than a css class in OL that changed name.

Ämne: [Gwt-openlayers-users] Safari and multiple urls for a WMS baselayer

I'm having a issue with Safari (4.0.5 on windows).
When I define a WMSlayer with a single url only it works fine, but when
initiate it with an array of url:s the urls: are combined into a string
where each url is separated with an ',' and this string is then used as
the url to the WMS server.

The constructor I call is:
WMS.java
public WMS(String name, String[] urls, WMSParams params, WMSOptions
layerParams) {
	this(WMSImpl.create(name, new JStringArray(urls).getJSObject(),
params.getJSObject(), layerParams.getJSObject()));
}

I've looked into JstringArray() and it simply copies all values from
urls to a JStringArray so no problem there.
In WMSImpl there is a comment about the Object/Array problem and this is
solved by once more copying the values from the new array, seems ok. The
new value is then passed to OpenLayers.Layer.WMS.

So the bottom line is that I have no idea why this works in all mayor
browsers except Safari. When I only use 1 url there is no problem. We
have another OpenLayers (plain OpenLayers, non-GWT) application which
also uses multiple url and that app does not show this symtoms.

Anyone got a clue?

Hi guys, thanks for the swift replies.

I don't think I've got a problem with SmartGWT after all, GWT-Openlayers has
just decided to break for me!  I've started a new Eclipse project and now
can't get it working at all.  I have no idea what's changed, but I get the
following error:

Hi,

for me it worked by putting the mapwidget in a dockpanel:

DockPanel dp = new DockPanel();
dp.setHeight("100%");
dp.setWidth("100%");
dp.add(OLmap.getMapWidget(), DockPanel.CENTER);
window.addItem(dp);

Cheers,
Philipp

Haven't tried with smartGWT but I guess that the map doesn't get sized. 

Check with firebug (or any other inspect tool) what size the div containing the map has. If it's 0x0 then try to set a larger size in firebug.  if you're lucky the map shows and you can start trying different strategies to get it sized.

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

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] Producing clickable layers from WMS

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

I will within a two weeks add this functionality to our app, (we're currently using WFS but need to handle larger amount of data which get impossible to load with WFS). 

The plan is to use the technique shown in http://openlayers.org/dev/examples/getfeatureinfo-popup.html to be able to produce popups for WMS-layers as well.

I'm not sure if gwt-ol implements all that I need to use, but if not, I will implement those parts myself and send them back as a patch.

Hi Philipp,

I needed this kind of functionnality, but I didn't use WMS, just WFS.
The idea is to get your polygons from the WFS protocol, and load them into your VectorLayer. If your polygons are static, you can even use GML files. But I'm not sure that's what you're looking for, as this solution implies the WMS is completely independant from the polygons.

Ask me if you want more info, I could even provide you with sample code if you want.

Cheers,
Mikael

Hi,
 
I'm looking for a solution to make any wms layer clickable. That means that there should be areas - which are bounded by a polygon - that show an information bubble when hovering over.
Does anyone have experience in this field? As far as I know gwt-openlayers does not support this feature.

I found a suitable example for openlayers using a WFS:
http://openlayers.org/dev/examples/getfeature-wfs.html

It is possible to add the needed funcionality and build the .jar by myself, right?!

I'm thankful for any idea or comment on this.

Cheers,
Philipp

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

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

Hi,

I'm looking for a solution to make any wms layer clickable. That means that
there should be areas - which are bounded by a polygon - that show an
information bubble when hovering over.
Does anyone have experience in this field? As far as I know gwt-openlayers
does not support this feature.

I found a suitable example for openlayers using a WFS:
http://openlayers.org/dev/examples/getfeature-wfs.html

It is possible to add the needed funcionality and build the .jar by myself,
right?!

I'm thankful for any idea or comment on this.

Cheers,
Philipp
