Hello Miriam,
To observe changes on the data tree, you can use these two functions:
DataEntityList::AddObserverOnAddDataEntity()
DataEntityList::AddObserverOnRemoveDataEntity()
There's an example on how to use them in the function:
DataEntityListBrowser::InitConnections( ).
However, if you need to observer changes in the rendering tree
(after the data is rendered), you need to use the function
AddObserverOnModified(). You can find an example in the function
RenderWindowBase::SetPrivateRenderingTree().
Best regards,
Xavi
