Thanks for your responses.
I know how to create a custom panel and how to use
"SimpleDoubleInformationHelper". My problem is how to get
a "DoubleArrayInformationHelper" from a vtkDoubleArray
with unknown size and send it to my custom panel. The
compoment of this vtkDoubleArray ( called "VolumesArray"
here) will be added in ResquestData().
I found a way to do it:
XML:
<StringVectorProperty
name="VolumesArray"
command="GetVolumesArray"
information_only="1">
<SimpleStringInformationHelper/>
</StringVectorProperty>
In RequestData(), I will set VolumesArray to some values
like "1223.44|2244.09|233232|..." Note the "|" separator
after each volume.
In my .ui, I created a QLineEdit with the same name
("VolumesArray").
In my pqCustomPanel.cxx:
pqComputeVolumes::pqComputeVolumes(pqProxy* pxy, QWidget*
p) :
pqLoadedFormObjectPanel(":/CustomWidget/pqComputeVolumes.ui",
pxy, p)
{
this->volumes =
this->findChild<QLineEdit*>("VolumesArray");
this->volumesList =
this->findChild<QListWidget*>("volumesList");
this->volumes->setVisible(false);
QObject::connect(this->volumes, SIGNAL(textChanged(const
QString&)),
this, SLOT(onShowVolumesList(const
QString&)),Qt::QueuedConnection);
this->linkServerManagerProperties();
}
void pqComputeVolumes::onShowVolumesList(const QString&
text)
{
int i=0;
QStringList list =
text.split("|",QString::SkipEmptyParts);
foreach( QString v, list)
{
i++;
this->volumesList->addItem("Volume " +
QString::number(i) + " " + v);
}
}
This works fine for me but I think there is an easier way.

If its because its an information property, I think
adding a show="1" attribute to the property will make it
show up.

You will have to create a custom panel. Look at the

Hi,
I am trying to use "DoubleArrayInformationHelper" to get
a vtkDoubleArray
from server side and show it in my filter GUI.
XML code:
<DoubleVectorProperty
name="volumesArray"
command="GetVolumesArray"
information_only="1">
<DoubleArrayInformationHelper/>
</DoubleVectorProperty>
C++:
vtkDoubleArray* GetVolumesArray()
{
return this->volumesArray;
}
The current code don't show anything in the GUI.
I would like to see the content of volumesArray in a
Table, List or a Tree
widget.
How can I do that ?

To get back "values" from the server, you can use either
"information
properties" or "information objects".
Information properties are properites with
information_only="1" set
in
the XML (eg. in
Servers/ServerManager/Resources/rendering.xml the
"Camera" proxy has "CameraPositionInfo" as an
information
property).
Such properties need an "InformationHelper" which knows
how to obtain
the values from the server. For simple Get*() methods,
you can use the
<SimpleDoubleInformationHelper/> or
<SimpleIntInformationHelper />
etc. based on the type of the property. Complex
information helpers
can be written as well. Look at
TimeStepsInformationHelper
(vtkSMTimeStepsInformationHelper.h|cxx) as an example.
Information objects are used to get data from server
which cannot be
simply put in a property for example information about
the data object
produced by a filter (vtkPVDataInformation). These are
vtkPVInformation subclasses. You can create you own
vtkPVInformation
subclass that knows how to collect information and then
serialize/deserialize it for transfer to the client from
the server
(if needed). To gather such information, one uses
vtkProcessModule::GatherInformation(vtkIdType
connectionID,
vtkTypeUInt32 serverFlags, vtkPVInformation* info,
vtkClientServerID
id) where "id" is vtkSMProxy::GetID() returned for the
proxy from
which you want to collect the information.
In your case, information property may be an easier
solution -- if I
understand your problem correctly.
There is a pqServerManagerModel instance
accessible as
pqApplicationCore::instance()->getServerManagerModel()
that can be
used to access sources/filters their representations,
views etc. Take
a look at Qt/Core/pqServerManagerModel.h for the API.
That should help
you access the visualization pipeline.
"How to get, for instance, the ids of the nodes which
are displayed
after the application of a filter to the model ?"
Not sure I understand what you mean by that. Can you
please elaborate?

Hey all,
I'm programming a filter with a custom Object Panel,
and I'm feeling a little bit lost about the ParaView
architecture and
code design.
My great problem is the comunication between the
Object Panel and the Model. I know I can't have a
pointer to my
vtkUnstructuredGrid displayed, 'cause they are not
necessarily at the
same machine or process. I also know that I'm able to
send information
to the model through properties, since I can get the
vtkSMProxy in my
panel. But what about the way back ? Is there a way to
send information
from the display view to the panel ? How can I display
in a QTable, for
instance, the nodes of my model which have some property
equals to 1 ?
Another problem is the Visualization Pipeline: is there
a way to
"walk" on
it ?
I mean, if I have a filter name, am I able to get the
the filter no
matter where it is in the Pipeline ?
Sorry for the mess with the questions. I hope I made it
clear and someone
can help me ! :)
Regards,
Rafael March.
