[Paraview-developers] What widget is used for the the check box selection?

[Cory Quammen]

Hi Josh,

Do you have a custom filter/source you are writing as a plugin? If so,
you just need to define certain methods in your filter/source and
configure your plugin XML a certain way.

Say you want to have checkboxes selecting a subset of point data
arrays from the input. The methods you need are:

  // Description:
  // Get number of point data arrays
  int GetNumberOfPointArrays();

  // Description:
  // Get name of a point data array at index
  const char* GetPointArrayName(int index);

  // Description:
  // Get/set the status of a point data array of a given name
  void SetPointArrayStatus(const char *name, int status);
  int GetPointArrayStatus(const char *name);

Now in the XML for your filter, you need something like this:

      <StringVectorProperty information_only="1"
                            name="PointArrayInfo">
        <ArraySelectionInformationHelper attribute_name="Point" />
      </StringVectorProperty>
      <StringVectorProperty command="SetPointArrayStatus"
                            element_types="2 0"
                            information_property="PointArrayInfo"
                            label="Point Arrays to Evaluate"
                            name="ArrayStatus"
                            number_of_elements="0"
                            number_of_elements_per_command="2"
                            panel_visibility="default"
                            repeat_command="1">
        <ArraySelectionDomain name="array_list">
          <RequiredProperties>
            <Property function="ArrayList"
                      name="PointArrayInfo" />
          </RequiredProperties>
          </ArraySelectionDomain>
        <Documentation>
        </Documentation>
      </StringVectorProperty>

I cribbed this from the XML descriptions in one of the readers in
ParaView/ParaViewCore/ServerManager/SMApplication/Resources/readers.xml

I hope that helps,

Cory
