We can check if a the example tree is modified, and change the modification state of the tree as follows:

\code
// Check if the tree is modified
if (rootNode->isModified()){
  // If it is modified, we change its modification state to false for this example:
  rootNode->setModificationState(false,IModificationNotifier::NotifySubjects);
}
\endcode

Tree nodes also provide a number of signals which can be monitored if you are interested in specific changes in a tree. See the Qtilities::Core::Observer c
