Re: Floating label

[Raphaël Brugier]

How is your label added to the page ?
You  should try to display your label inside a popupPanel.

Re: GWT + app engine: how do I avoid double-work?

[Raphaël Brugier]

Since GWT 2.0 classes with JDO or JPA annations can be serialized over
gwt-rpc
see

Re: GWT Developer Plugin is not found in Firefox

[Raphaël Brugier]

Hi,

I am sorry but this solution didn't work for me.

I didn't understand if the symlink to create is from libnspr4.so.0d to
libnspr4.so as mentionned there
or from libnspr4.so.0d to libnspr4.so as mentionned in this thread :
https://groups.google.com/group/google-web-toolkit/msg/4695e012cb9001e0

Here is what a ls -la /usr/lib64 give :

...
lrwxrwxrwx  1 root root   14 29 mai   19:03 libnspr4.so ->
libnspr4.so.0d
lrwxrwxrwx  1 root root   20 29 mai   18:38 libnspr4.so.0d -> /usr/
lib/libnspr4.so
...

I am running on Archlinux 64 bits an Firefox 3.6.3

Thanks in advance.

Re: GWT server design

[Raphaël Brugier]

Gwt is client side, so it's just totally depends on how many numbers
of request you'll do from your gwt application to your server.
You can even have no request at all, just the first download of the
application.

Re: enum serialization

[Raphaël Brugier]

The serialization of inner enum works for me,

Be sure to have a default constructor in your enum.
Maybe also non-final fields.

Does your class is on a serializable package, usually the client or
shared ?

Re: Grouping Table Implementation

[Raphaël Brugier]

Yes, we did a similar thing just last week.
Just use cellTable.setRowSpan(row, colum, depth) on the cell you want to 
group and then delete the cell on the next row using 
cellTable.deleteCell(row, cell).
This is just the normal way to group cells in a html table but using the 
cellTable api.

Re: CellTable odd/even row styles

[Raphaël Brugier]

The good way to override the style of a cellTable is to pass a Ressource to 
the constructor.
See the Expense 
example

Styling Cell individually in CellTable

[Raphaël Brugier]

Hi,

I've got a use case with the CellTable where a cell should be rendered with 
a different background color depending on the cell content. I've also some 
TD with a rowspan > 1. 
I've implemented an AbstractCell to set a style depending on the status 
(short version) :

public class StatusCell extends AbstractCell {
@Override
public void render(final Status status, final Object key, final 
SafeHtmlBuilder sb) {
String cellStyle;
if (status == Status.OK) {
cellStyle = "greenCell";
} else {
cellStyle = "redCell";
}
sb.appendHtmlConstant("");
sb.appendEscaped(status.toString());
sb.appendHtmlConstant("");
}
}

Here is the result : 




Product
Status






car



OK





car




car



KO






But the point is that when the cell is rendered by the CellTable view, it 
encapsulates it inside an other DIV and then put it in the TD. Then my Div 
where I have applied a style will not have the max height of the TD so the 
background color will not be fully applied to the TD. (The green of the OK 
cell does not extend to the TD)


I got two ideas : 
1/ Use css to extends the DIV to be the height of the TD. But setting 
height: 100% did not work.
2/ Find a way to set manually a style to the . But there is nothing on 
the CellTable api to access the TD after they have been rendered.

Is anybody have encountered this use case or have a solution please ?

Thanks in advance.

Re: CellTable Grouping

[Raphaël Brugier]

By grouping you mean set a rowspan ?

You can set the rowspan of cell using the cellTable api : 

public void setRowSpan(final int row, final int column, final int 
rowSpan) {

cellTable.getRowElement(row).getCells().getItem(column).setRowSpan(rowSpan);
}

Re: Code Split

[Raphaël Brugier]

Hi,

To get information on how your code is split you can use the soyc (story of 
your compile) flag, see:
http://code.google.com/webtoolkit/doc/latest/DevGuideCompileReport.html

To get information on when your splitted code is loaded, use the speed 
tracer plugin for chrome:
