Hello,
I am trying to copy proxy properties from xml state. the
folowing code work well for "sources" proxies. It works
also for "representations" proxies, but Instead of copying
properties to the existing representation, it create
another representation and I got this error:
"vtkSMStateLoader (0A075FD0): No root is defined. Cannot
locate proxy element with id 74"
In Paraview I got two representations for the same source.
Here is my code:
void pqPowerView::loadProxyFromState(vtkPVXMLElement
*stateElement,
vtkSMProxy
*smProxy )
{
vtkSMProxyManager* pxm = vtkSMObject::GetProxyManager();
vtkSMStateLoader *myLoader = vtkSMStateLoader::New();
vtkPVXMLElement* collectionElement =
vtkPVXMLElement::New();
unsigned int numElems =
stateElement->GetNumberOfNestedElements();
unsigned int i=0;
for (i=0; i<numElems; i++)
{
vtkPVXMLElement* currentElement =
stateElement->GetNestedElement(i);
if (currentElement->GetName() &&
strcmp(currentElement->GetName(), "Proxy") == 0)
{
currentElement->AddNestedElement(collectionElement);
if(QString(currentElement->GetAttribute("group")) ==
smProxy->GetXMLGroup()
&& QString(currentElement->GetAttribute("id")) ==
QString(smProxy->GetSelfIDAsString()) )
{
vtkSMProxy *newProxy =
pxm->NewProxy(smProxy->GetXMLGroup(),
smProxy->GetXMLName());
newProxy->LoadState(currentElement, myLoader);
this->copyProxy(newProxy,smProxy);
if(!smProxy)
qDebug() << "proxy not loaded";
}
}
}
}
void pqPowerView::copyProxy(vtkSMProxy* src, vtkSMProxy*
dest)
{
vtkSMPropertyIterator* iter =
dest->NewPropertyIterator();
for (iter->Begin(); !iter->IsAtEnd(); iter->Next())
{
vtkSMProperty* destProp = iter->GetProperty();
vtkSMProperty* srcProp =
src->GetProperty(iter->GetKey());
if (destProp && srcProp)
{
destProp->Copy(srcProp);
}
}
iter->Delete();
}
can you please tell me what am doing wrong ?
the goal is to restore the exposed properties for the xml
state.
