Thank you Xavi,
I have been testing both:
1.- DataEntityList::AddObserverOnAddDataEntity()
DataEntityList::AddObserverOnRemoveDataEntity()
2.- AddObserverOnModified()
Both works perfect, but, the fact is that I need to observer changes in the
rendering tree, after the data is rendered, but only on adding a new Data
Entity, to achieve a more efficient code, because I do something just in case
is a new data entity otherwise I do nothing.
Is possible to observe changes only in case I add a new Data Entity and after
the data is rendered? Some like GetRenderingTree()->AddObserverOnAddDataEntity()
Thank you very much.
MIRIAM

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
