Hi Mark,
Here are what I have tried within my custom reader panel (a subclass
of pqAutoGeneratedObjectPanel) so far and working fine for me. But I
may be wrong as Fabian reported the third one didn't for him.
( http://www.paraview.org/pipermail/paraview/2009-October/014074.html )
// 1. If one is happy with only updating the active view
if(this->view()) // may be null if no active view is present
{
this->view()->render();
}
// 2. All relevant views may be rendered this way, where Ps is a
// pqPipelineSource (a subclass of pqProxy) passed to the constructor
// of the reader panel class
this->Ps->renderAllViews();
// 3. All views including irrelevant ones may be rendered by
pqApplicationCore::instance()->render();
// 4. Or there may be another way something like
vtkSMProxyIterator *pIt = vtkSMProxyIterator::New();
pIt->SetModeToOneGroup();
for(pIt->Begin("views"); !pIt->IsAtEnd(); pIt->Next())
{
vtkSMViewProxy::SafeDownCast(pIt->GetProxy())->StillRender();
}
pIt->Delete();
