Hi Noelia,
This line of code is correct. However, you can try to isolate the
problem, not adding the data to the rendering tree of your working area. You
can add the data to the data entity list only, after this, using the user
interface, change to the standard OrthoSliceWorkingArea, and visualize your
output signal in the signal viewer, using the check box:
Core::DataEntity::Pointer dataEntity = dataEntityHolder->GetSubject(
);
if ( dataEntity.IsNotNull() )
{
// Add to list and connect holders
DataEntityHelper::AddDataEntityToList( dataEntityHolder,
false );
}
DataEntity is a container. When the processor calls UpdateOutput( ),
it creates a new DataEntity holding the pointer to the data created by your
processor (in your case it is blSignalCollective). The DataEntity will be
destroyed when there are no references pointing to it. When the user removes
the DataEntity from the data tree, it sends an event to all widgets to
remove the references to this DataEntity.
Best regards,
Xavi

Subject: RE: Signal working area
Hello.
I tried to do what you told me, and both the processor and in the
OnModifiedOutputDataEntity my data signal are correct, but when viewing in
the corresponding dataEntity happens what I said earlier, maybe it is
because this well done publish output?
Core:: DataTreeHelper:: PublishOutput (m_Processor->
GetOutputDataEntityHolder (0), GetRenderingTree ());
I thought that dataEntity destroy or initialize the output but not very
well how, I've seen Core:: RenderingTreeMITK:: OnDestroyDataEntity (), but
not as relating to the right dataentity.
You can help me?
Thank you very much!
