[Paraview] Re : Problem -> How to display informations in a plugin GUI ?

[R M]

Hi,

I have not yet found the solution.I have followed this example: 
http://www.paraview.org/pipermail/paraview/2008-November/010217.html but still 
have problems.
In my plugin xml file I have this:

<DoubleVectorProperty
        show="1"
        name="Result"
        label="Result
        command="GetResult"
        number_of_elements="1"
        default_values="0"
        information_only="1">
        <SimpleDoubleInformationHelper />
    </DoubleVectorProperty>

In my plugin source file, I have this:
double GetResult()
{
    return m_result;
}

I have a class that inherit from pqAutoGeneratedObjectPanel:
#include "MyPluginPanel.h"

#include <QLineEdit>

#include "vtkSMDoubleVectorProperty.h"
#include "vtkSMProperty.h"
#include "vtkSMProxy.h"

MyPluginPanel::MyPluginPanel(pqProxy* object_proxy, QWidget* _parent)
:pqAutoGeneratedObjectPanel(object_proxy, _parent)
{
    p_resultWidget = this->findChild<QLineEdit*>("Result");
    
    if( this->findChild<QLineEdit*>("Resylt") )
    {
        qWarning() << "NULL Widget Pointer";
        return;
    }

    p_resultWidget->setReadOnly(true);
}

MyPluginPanel::~MyPluginPanel()
{}

void MyPluginPanel::updateInformationAndDomains()
{
    pqAutoGeneratedObjectPanel::updateInformationAndDomains();
    updateDoubleValue(p_resultWidget, "Result", 0);
}

void MyPluginPanel::updateDoubleValue(QLineEdit* qLineEdit, QString property, 
qint32 index)
{    
  vtkSMProperty* smProperty = this->proxy()->GetProperty(property.toAscii());
  if (!smProperty)
   {
     qWarning() << "SMProperty [double] was NULL for " << property.toAscii();
     return;
   }
   vtkSMDoubleVectorProperty* dvp = 
vtkSMDoubleVectorProperty::SafeDownCast(smProperty);
 
   double value = dvp->GetElement(index);
   
   qLineEdit->setText(QString::number(value));   
}

The problem is that the widget resultWidget  is always NULL.  But I can have the 
good result.

So, what's wrong with my code ?

Why the widget doesn't appear in the GUI plugin in Paraview ?

Thank you for your attention and your advice.

Hi,

I develop a plugin that and in its corresponding xml file, I have a 
doubleVectorProperty in which I would like to write the result of my filter and 
I don't want to make it editable.
So, I am looking for some examples of doing this beacause I really don't know 
how to do this and that make a while I want to make it. I have found nothing 
about this in the Paraview Guide book.

Here's what I have written in the plugin xml file:

<DoubleVectorProperty
        name="GetResult"
        command="GetResult"
        information_only="1">
        <SimpleDoubleInformationHelper/>
     </DoubleVectorProperty>
    
    <DoubleVectorProperty
       name="Result"
       command="SetResult
       number_of_elements="1"
       default_values="0.0"
       information_property="GetResult">
    </DoubleVectorProperty>

and the code in the source is:
double GetResult()
{
    return m_result;
}

void SetResult(double value)
{
    m_result = value;
}

Then, in my code, when I would like to update this lineedit in the plugin GUI I 
call SetResult(myResult). But nothing happen and the lineedit in the plugin GUI 
is editable (which I don't want).

Thank you for your advise.
