Re: [Paraview] vtkSMProxy saving/restoring

2008-11-20 Thread Nehme Bilal 


Hello,

Instead of saving a copy of a proxy, I'm trying to use 
lookMarkModel state to get the exposed properties and 
restore it to servermanager proxies.

I'm trying to do something like that:

vtkSMProxyManager* pxm = vtkSMObject::GetProxyManager();
vtkSMProxy *smProxy;

1- convert the stored lookmark state from a qstring to a 
vtkPVXMLElement:


  vtkPVXMLParser *parser = vtkPVXMLParser::New();
  parser-Parse(lookMarkState.toAscii().data());
  vtkPVXMLElement *stateElement = 
parser-GetRootElement();

  if(!stateElement)
{
qDebug()  Could not parse lookmark's state.;
parser-Delete();
return;
}

2- now from this state I want to copy the exposed 
properties:

for (?? xmlProxy in stateElement ??)
{
  smProxy = pxm-GetProxy(??xmlProxy groupeName??, 
??xmlProxyName??);
  vtkSMPropertyIterator* iter = 
smProxy-NewPropertyIterator();


  for(iter-Begin(); !iter-IsAtEnd(); iter-Next())
  {
vtkSMProperty* smProp = iter-GetProperty();
vtkSMProperty* xmlProp = 
??xmlProxy-GetProperty(iter-GetKey())from??

if (destProp  srcProp)
{
destProp-Copy(srcProp);
}
   }
   iter-Delete();
 }

how can I do that ?

thanks !

Ah I think I know the problem. vtkSMProxy::Copy() copies 
all properties even those on the sub proxies. A 
representation is a complex beast with several internal 
subproxies which are linked up internally. You actually 
simply want to save/restore the exposed properties so 
I'd do something 
like follows:


void Copy(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();
}

Use the above Copy instead of vtkSMProxy::Copy().

Hi again,

I did save and restore the source proxy and 
representations and it's 
working.
All display properties are saved/restored perfectly, but 
after 
restoring, changing color or Style properties from 
the object 
inspector has no effect. Other properties like visible 
or 
Transformation works !


after restoring I called:
vtkSMObject::GetProxyManager()-UpdateRegisteredProxiesInOrder();

but it didn't solve the problem.

Re: [Paraview] vtkSMProxy saving/restoring

2008-11-19 Thread Geoff Draper 

Hello,

I'm also facing a related problem when I save/restore vtkSMProxy's. The 
proxy ID is stored in the XML file. So when I reload the proxies, the 
StateLoader attempts to recreate the proxy with the same ID as before. 
But because I'm running a new ParaView session, sometimes the saved ID 
has already been reserved by another object in the current session, 
causing a collision.


When this happens, ParaView aborts inside the function:
vtkClientServerInterpreter::ProcessCommandAssign(const vtkClientServerStream 
css, int midx)
The error message is Attempt to assign existing ID.

Has anyone else ever dealt with this before?  Is there a known workaround? 
Am I completely off base?


Thank you!

but nothing is restored ! why? Is there any other way to do that?
(suppose that I have only on source)

Thank you

Re: [Paraview] vtkSMProxy saving/restoring

UndoRedo states are not meant to loaded across different sessions. If 
loaded in the same session such ID conflicts should not occur.

Hello,

I'm also facing a related problem when I save/restore vtkSMProxy's. 
The proxy ID is stored in the XML file. So when I reload the proxies, 
the StateLoader attempts to recreate the proxy with the same ID as 
before. But because I'm running a new ParaView session, sometimes the 
saved ID has already been reserved by another object in the current 
session, causing a collision.


When this happens, ParaView aborts inside the function:
vtkClientServerInterpreter::ProcessCommandAssign(const 
vtkClientServerStream css, int midx)

The error message is Attempt to assign existing ID.

Has anyone else ever dealt with this before?  Is there a known 
workaround? Am I completely off base?


Thank you!

it works but I have some problems like:
- after restoring the proxy, changing some display properties in 
Paraview has no effect (like color ...)
- only the display properties are saved/restored. (variables in 
object inspector properties tab are not restored)


It's probably the way that I'm casting the source proxy and some 
staff like that.


I'll try to solve these problems and let you know.

Re: [Paraview] vtkSMProxy saving/restoring

For saving the object inspector properties you'll have to save/restore 
the state for the source proxy (and not merely it's representation proxy).

Re: [Paraview] vtkSMProxy saving/restoring

2008-11-19 Thread Utkarsh Ayachit 
Ah I think I know the problem. vtkSMProxy::Copy() copies all properties 
even those on the sub proxies. A representation is a complex beast with 
several internal subproxies which are linked up internally. You actually 
 simply want to save/restore the exposed properties so I'd do something 
like follows:


void Copy(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();
}

Use the above Copy instead of vtkSMProxy::Copy().

Hi again,

I did save and restore the source proxy and representations and it's 
working.
All display properties are saved/restored perfectly, but after 
restoring, changing color or Style properties from the object 
inspector has no effect. Other properties like visible or 
Transformation works !


after restoring I called:
vtkSMObject::GetProxyManager()-UpdateRegisteredProxiesInOrder();

but it didn't solve the problem.
