    I try this (gwt-openlayer into smartclient widget added to smartclient vertical panel) , but there are problems with native events of openlayers: pan (drag map), zoom (double clic), zoom to rectangle (ctrl+drag) not are sended from client to native javascript of openlayers, then nothing happens.
    Can someone help?

    Mapstraction

    Is there a plan to include Mapping API support via Mapstraction (like GWT-Ext 2.0.3)?

    Like still none mailing list /forum for gwt-openlayers project. Possible to use feature/bug/patch tracker at sourceforge.

    gwt-openlaers compatible with last 2.4-2.7 openlayers api

    The fix to my last problem was to use no arg constructors as follows:

    Code:
    		map.addControl(new PanZoomBar());
    		map.addControl(new MousePosition());
    		map.addControl(new Scale());
    I am all set now but for the questions: What is the correct mailing list /forum for gwt-openlayers project. Thanks again.

    Adding the following in my Application.html file just before the close of body tag worked:

    Code:
        <script src="http://www.openlayers.org/api/OpenLayers.js" type="text/javascript"></script>
    Now I have one last question which is specific to using OpenLayers with SmartGWT.

    The following code from the tutorial needs to be fixed for SmartGWT not using RootPanel:

    Code:
    		map.addControl(new PanZoomBar(RootPanel.get("nav").getElement()));
    		map.addControl(new MousePosition(RootPanel.get("position").getElement()));
    		map.addControl(new Scale(RootPanel.get("scale").getElement()));
    Can you please tell me what to replace it with. At present I am getting NPE. Thanks very much for all your help.

    I'm don't use maven and not is specialist in the ant/maven, sorry (only use them for build projects). For gwt-oprnlayers use ant.

    Aah! That must be the problem. Thanks gev.

    It appears that gwt-openlayers does not automatically include OpenLayers.js. Could this not be fixed in the pom.xml for gwt-openlayers? I would be glad to help. What list can I post to about that project?

    gev, do you know where I can find pom/jar for openlayers for maven projects?

    Thanks again for your help.

    Hi,

    I added the FileUpload widget from GWT to my smartGWT app.

    All I did was added the GWT widget as a member to existing smartGWT vStack.

    What I find difficult to understand is that it works fine in Chrome but doesnt show up in Firefox. I faced similar issues previously too with firefox nt displaying some smartgwt functionality and never found a way around it.

    Hope this helps.

    Cheers!

    Here is what I have learned...

    There is an error I encounter at the end and would be grateful if gev or someone else could help me understand the cause of that.

    Is there someplace I can read how to integrate GWT widgets with SmartGWT. The gwt-integration sample does not provide any details.

    I needed to use latest CVS bits because released version does not support GWT 1.5.x. Note I also had to modify the pom.xml file with following patch:

    Code:
    Index: pom.xml

    I tried the following for integrating the latest CVS bits of openlayers_gwt in my maven project.

    Added following to my pom:

    [CODE]
    <dependency>
    <groupId>com.eg.gwt.openLayers</groupId>
    <artifactId>openlayers_gwt</artifactId>
    <version>0.3.1-SNAPSHOT</version>

    Added following to my Application.gwt.xml module decsriptor:

    Code:
    <inherits name='com.eg.gwt.openLayers.OpenLayers'/>
    I then coded the following Canvas sub-class that creates a MapWidget as its child per tutorial here:

    }
    I then get the following error when I run the app in GWT shell.

    Thanks for any tips on how to fix above error.

    I have not used straight GWT components with SmartGWT. Since openlayer-gwt is straight GWT project I am wondering if there are any special tricks I need to be aware of. Thanks for sharing.

    gwt-openlayers

    There is one project gwt-openlayers at http://sourceforge.net/projects/gwt-openlayers. I'm use it inside smartGWT's widgets. This is (still partial) wrap opelayer's javascript API and with my patch openstreet API also.
    Use from CVS. Just (from 11.00 to 19.00 by Moscow) you can look example of using gwt-openlayers with openstreetmap at my book here: http://gwt.stkurier.ru/site.Site/Site.html#map

    started a topic SmartGWT wrapper for OpenLayers?

    SmartGWT wrapper for OpenLayers?

    I was wondering if anyone has done a SmartGWT wrapper for OpenLayers mapping service.

    Even better would be something like Mapstraction from GWT-Ext.

    Does SmartClient have any plans in this area? Thanks.
Working...
