Mal.

hi Mal,

#1
add issue ticket (and star it) on google gwt api project issue list,

#2
I've done many ajax apis functionality myself recently, including full
Ajax Loader implementation, Language API and some of Visualization API
with 1.5 new JavaScriptObject implementation. What is functionality
form V* api you would use? Maybe I could help,

regards,
Peter

I too, am interested on this.

How would I import a visualization object into GWT?
Is there a way of java mapping of the visualization api in GWT?

Thanks

Check me off as "Me Too". In the mean time I have been using it via
JSNI with help from peter.

Here is the thread that may be of help to you. So far its doing what I
want, although if there is ever a gwt-visualization package I will
re-write.

Seems it wouldn't be too bad writing gViz wrapper into GWT. Anyone
wants to help me with it?

hi John,

will you be using gwt 1.5RC (and later when released)?
(this release really simplify things)

regards,
Peter

[John]

Hi Peter:

Yes. I will be.

I will post what I have once I have something.

Thanks

I hacked up something to get the piechart working via gwt.

This is not the complete implementation, I still need to learn more
about gwt.

You can download from:
www.browseengine.com/src.tar

included is the modified default MyApplication.

I will add to it once I figure out more about gwt.

Let me know how it works out for you.

Thanks

Peter:

I can't figure out how to build this as a separate jar to be
included into my gwt project. I had to move the src code into my
project for it to work.

hi John,

when I found time I'll give a help to you, After seeing your files I
think you're writing to complex code,
consider such 1.5RC implementation of google.visualization.DataTable
compared to your current one:

package google.visualization;

import com.google.gwt.core.client.JavaScriptObject;

public class DataTable {
static class DataTableImpl extends JavaScriptObject {
static native DataTableImpl create()
/*-{
return new $wnd.google.visualization.DataTable();
}-*/;

protected DataTableImpl() {
}

public native final void addColumn(String dataType, String name)
/*-{
this.addColumn(dataType, name);
}-*/;

public final native void addRows(int i)
/*-{
this.addRows(i);
}-*/;

public final native void setValue(int row, int column, String value)
/*-{
this.setValue(row, column, value);
}-*/;

public final native void setValue(int row, int column, int value)
/*-{
this.setValue(row, column, value);
}-*/;

}

DataTableImpl impl;

public DataTable() {
impl = DataTableImpl.create();
}

public void addColumn(String dataType, String name) {
impl.addColumn(dataType, name);
}

public void addRows(int i) {
impl.addRows(i);
}

public void setValue(int row, int column, String value) {
impl.setValue(row, column, value);
}

public void setValue(int row, int column, int value) {
impl.setValue(row, column, value);
}

}

with such implementation it can be used "as is" with code pasted from
Google Ajax api docs:

DataTable data = new DataTable();
data.addColumn("string", "Task");
data.addColumn("number", "Hours per Day");
data.addRows(5);
data.setValue(0, 0, "Work");
data.setValue(0, 1, 11);
data.setValue(1, 0, "Eat");
data.setValue(1, 1, 2);
data.setValue(2, 0, "Commute");
data.setValue(2, 1, 2);
data.setValue(3, 0, "Watch TV");
data.setValue(3, 1, 2);
data.setValue(4, 0, "Sleep");
data.setValue(4, 1, 7);

regards,
Peter

Hi Peter:

Thanks!

I thought according to the javadoc, JavaScriptObject should NOT
be extended. I am following the paradigm from Gears' source code.

Thanks

Just realized I could have just used the issue tracker:
Issue 2511

Thanks

created a project under google code:

please let me know if you can help.

Hi John,

I think it is great that you want to create GWT bindings for the visualization API.  There already is a project for these types of bindings: the gwt-google-apis (GALGWT) project.  If you are interested working on these bindings as part of that community, you should check out: Making GWT Better for how to get setup.  Get that lined up and we can create a branch for the development and get it integrated into the continuous build, etc.

GALGWT is near the end of a release cycle so these would be included in the next one.  

Cheers,

Hi Miguel:

Sure, that's the perfect place for it.

Are you gonna be creating a branch for me to check in?

Thanks

John

Hi John,

Could of things: did you sign and send back a CLA?  The Making GWT Better document talks about how to make contributions to GWT and the gwt-google-apis project uses the same rules.

I'll reach out to the internal Google Visualization API so that they can also provide feedback on the bindings.

Cheers,

Done.
Let me know what you need me to do next.

Thanks

Hi John,

I was talking to Miguel today and we are excited about your contribution.

- I think that one thing you could work on is a sample "HelloViz"
type of application.
- You can also look at the "Making GWT Better" and reformat the code
so that it passes all the GWT "checkstyle" rules - its pretty easy
once Eclipse is setup.

Regards,
-Eric.

Hi Eric:

I am working on the code convention and style setups.

Would you like me to add you or your team members to the project
so I can get some help?

Thanks
