I have a VTK class that takes two inputs:
int vtkRestorePolyDataPointIds::FillInputPortInformation(
int port, vtkInformation* info)
{
if ( port == 0 ) //this is the polydata we want to correct
{
info->Set(vtkDataObject::DATA_TYPE_NAME(), "vtkPolyData" );
return 1;
}
else if(port == 1) //this is the object we want to use to match the ids to
{
info->Set(vtkDataObject::DATA_TYPE_NAME(), "vtkPointSet" );
return 1;
}
return 0; //invalid port requested
}
So I made two InputProperty entires in the xml:
<!--input-->
<InputProperty
name="Input"
port_index="0"
command="SetInputConnection">
<ProxyGroupDomain name="groups">
<Group name="sources"/>
<Group name="filters"/>
</ProxyGroupDomain>
<DataTypeDomain name="input_type">
<DataType value="vtkPolyData"/>
</DataTypeDomain>
<Documentation>
Set the input point set.
</Documentation>
</InputProperty>
<!--target ids-->
<InputProperty
name="TargetIds"
port_index="1"
command="SetInputConnection">
<ProxyGroupDomain name="groups">
<Group name="sources"/>
<Group name="filters"/>
</ProxyGroupDomain>
<DataTypeDomain name="input_type">
<DataType value="vtkPointSet"/>
</DataTypeDomain>
<Documentation>
Set the target point set.
</Documentation>
</InputProperty>
However, if I create two sources ( a box and a cone), select one,
ctrl+click the other one, then go to the filters list, it is greyed
out. Can anyone see a problem with the above?
Thanks,
David
