Ext::TableView PagingToolBar

hello

i have my problems with Ext::TableView
it's used like in the extkitchenexample:

...
tableStat_ = new Ext::TableView();
tableStat_->setModel(stat_);
tableStat_->setAlternatingRowColors(true);
tableStat_->resize(800, 400);
tableStat_->setPageSize(10);
tableStat_->setBottomToolBar(tableStat_->createPagingToolBar());
...

but when it should be shown i get the following error:
"Wt internal error: TypeError: e is undefined, code: undefined,
description: undefined"

the problem is the last line, because when i do not set the toolbar the
table is rendered normally.

bye,
jörg.

Re: GraphicsMagick

Hey John,

Sorry for the long delay. We have worked hard on improving our
WRasterImage lately and in the process I have been using
graphicsmagick alot. Still, it is not entirely clear to me what is
going wrong. But I have never used Magick++, only the C API.

2011/2/25 John Robson <John.Robson@...>:
> I tried using the Magick++ in Wt, it compiles but gives error when open
> the site.

What error do you get? I would think that the only difference is that
Wt already initializes the graphicsmagick library for you. Perhaps
graphicsmagick cannot stand doing this twice ?

If this is still troubling you, can you prepare a self-contained test
case for the Wt version ?

Regards,
koen

Re: PostgreSQL Session Not Destroy

How are you seeing that the Postgres sessions continue?

Do you also delete the Wt::Dbo::backend::Postgres object when your Wt
session exits?

You may also want to consider using a Postgres connection pool to
avoid creating as many connections to the database as you have Dbo
sessions.

Well, the Dbo code still needs to be able to call the persist()
function and so your code has to make it available. Wt::Dbo uses the
persist() method to manipulate objects of your class (loading, saving,
updating, deleting, creating/dropping the schema).

For situations where you cannot modify an existing class, Wt allows
you to specialize a Wt::Dbo::persist<T> struct which allows you to
define the 'persist()' method outside the class T. But template
specializations are cumbersome (and ASFAIK, this method of defining
the persist() function is currently not even documented).

koen

Axis Chart resolution

Hi all,
is it possible to set a minimum resolution on the axis chart ? As
example plotting
the points:

(0, 1.112), (1, 1.113), (2.114)

leads to have reported on the Y axis the values: 1.11, 1.11, 1.11.

Putting a resolution of 10 as example would lead those 3 points as a
straight orizontal
line instead of a diagonal one and then wandering why on the y axis I
have all 1.11

Regards
Gaetano Mendola

I have tried asking the minimum value or the maximum valued displayed
on the axis (the autolimit is set) and i seems that the minimum and
maximum retrieved are the ones of the previous visualization.

So I guess the minimum and the maximum are not calculated when the model
is set or the addSeries is performed.

How then I retrieve the actual minimum and maximum ?

Using WAxis::setLabelFormat() you can configure the labels to show
more significant digits.

True. You can force the chart to recalculate its layout using
WCartesianChart::initLayout()

Would this lead to have 2 calls to initLayout each time the model changes?

cross-compiled hello.wt fails: "remote_endpoint() threw: Bad file descriptor"

Hi Koen, all,

First off, thanks for Wt, it looks very interesting!

Now to the issue...

I've cross-compiled boost 1.46, Wt 3.1.8 and hello.wt example
application for an ARM system. At runtime hello.wt terminates due to
"remote_endpoint() threw: Bad file descriptor" (see log below). Any
ideas?

# hello.wt --docroot . --http-address 0.0.0.0 --http-port 8080
