[Paraview-developers] custom object panel with additional information

[Lodron, Gerald]

Thanks, it worked!

But i can only use properties with number_of_elements=1, when i use mulitple number of elements it could not find the correct function definition....

I tried:
Void GetPlaneCoefficients( double& rdX, double& rdY, double& rdZ, double& rdD)
Void GetPlaneCoefficients( double* pdPl )
Void GetPlaneCoefficients( double a[4] )
Double* GetPlaneCoefficients()

With
      <DoubleVectorProperty
        name="PlaneCoefficients"
        command="GetPlaneCoefficients"
        number_of_elements="4"
         information_only="1"
        default_values="0 0 0 0">
      </DoubleVectorProperty>

But all failed, now I wrote:
    double GetPlaneCoefficientX();
    double GetPlaneCoefficientY();
    double GetPlaneCoefficientZ();
    double GetPlaneCoefficientD();
with
<DoubleVectorProperty
        name="PlaneCoefficientX"
        command="GetPlaneCoefficientX"
        number_of_elements="1"
        information_only="1"
        default_values="0">
        <Documentation>
         X value of planes normal vector.
        </Documentation>
      </DoubleVectorProperty>

      <DoubleVectorProperty
        name="PlaneCoefficientY"
        command="GetPlaneCoefficientY"
        number_of_elements="1"
        information_only="1"
        default_values="0">
        <Documentation>
        Y value of planes normal vector.
        </Documentation>
      </DoubleVectorProperty>

      <DoubleVectorProperty
        name="PlaneCoefficientZ"
        command="GetPlaneCoefficientZ"
        number_of_elements="1"
        information_only="1"
        default_values="0">
        <Documentation>
           Z value of planes normal vector.
        </Documentation>
      </DoubleVectorProperty>

      <DoubleVectorProperty
        name="PlaneCoefficientD"
        command="GetPlaneCoefficientD"
        number_of_elements="1"
        information_only="1"
        default_values="0">
        <Documentation>
           Distance value from origin to plane.
        </Documentation>
      </DoubleVectorProperty>

Which is a little bit nasty, anyone knows what I am making wrong?

Thanks, best regards,
Gerald

Hi Gerald,

In your XML definition of your proxy you need to specify "an information" property. Like follow:

      <IntVectorPropery command="GetLevelRange"
                        default_values="0 0"
                        information_only="1"
                        name="LevelRange"
                        number_of_elements="2">
       </IntVectorPropery>

Then on the client side in order to get the value back, you will need to do something like that.
The code is based on memory not on actual real C++ code, but that should be enough to help you out.

proxy->UpdatePropertyInformation();
prop = vtkSMPropertyHelper(proxy, "LevelRange");
cout << prop.GetValue() << endl;

Hello

Is there a way to display some additional output from filter computation in the custom object panel or information panel? I programmed a custom paraview plugin with a filter and a custom object panel for some filter settings and now want to display some meta information of computation, e.g. Computation Time, Number of used iterations, etc....

I think I must overwrite the "updateInformationAndDomains()" function in my panel to set a QLabel for outputting such thinks but I have no clue how to get to the "GetProcessingTime" of my filter. I think it must be something like that:

vtkSMSourceProxy* poSourceProxy = vtkSMSourceProxy::SafeDownCast(this->proxy());
    if( !poSourceProxy )
        return;

    vtkSMProperty* poProcessingTime = poSourceProxy->GetProperty("GetProcessingTime");

but I have no clue what to write into the xml or how to get the return value from GetProcessingTime....

I searched for an example doing this but cannot find anything, for any help I would be very thankful...

Best regards,
Gerald
