[Paraview-developers] Filter plugin, xml properties for arrays

[Lodron, Gerald]

Hi

I want to make a filter plugin where i do not know how to set the xml file for the properties panel, may some expert can give me a hint:

The filter has has two inputs (both vtkPolyData Objects ) with optional point based arrays. The user should optionally be able to select none ore an arbitrary amount of these arrays with an additional float value, so the member function of my filter has this signature:

    void EnableAttributeArray( const char* pcArrName, float fFactor );
    void ClearAttributeArrays();

It would also be nice if only those arrays would be displayed which are have same name in both inputs...

Currently i have made a list with array names of first input, no check for beeing in both inputs and no possibility of selection of the fFactor float value:

<InputProperty
         name="Target"
         command="AddInputConnection"
         clean_command="RemoveAllInputs">
        <ProxyGroupDomain name="groups">
          <Group name="sources"/>
          <Group name="filters"/>
        </ProxyGroupDomain>
        <DataTypeDomain name="input_type">
          <DataType value="vtkPolyData"/>
        </DataTypeDomain>
        <!--<InputArrayDomain name="input_array" attribute_type="point"/>-->
        <InputArrayDomain name="input_array" />
</InputProperty>
<InputProperty
         name="Source"
         command="AddSourceConnection"
         clean_command="RemoveAllSources">
        <ProxyGroupDomain name="groups">
          <Group name="sources"/>
          <Group name="filters"/>
        </ProxyGroupDomain>
        <DataTypeDomain name="input_type">
          <DataType value="vtkPolyData"/>
        </DataTypeDomain>
</InputProperty>

<StringVectorProperty clean_command="ClearAttributeArrays"
                            command="EnableAttributeArray"
                            label="Add array to distance measure"
                            name="SelectArrays"
                            default_values="0"
                            number_of_elements_per_command="1"
                            repeat_command="1" >
        <ArrayListDomain name="input_array">
                <RequiredProperties>
                <Property function="Input"
                      name="Source" />
                 <Property function="Input"
                      name="Target" />
                </RequiredProperties>
        </ArrayListDomain>
</StringVectorProperty>

If someone could help me it would be great
