Esempi

Nell'esempio seguente viene illustrato come utilizzare la proprietà Type di un oggetto ContextNodeBase denominato selectedNode. Il testo di un oggetto TextBox, selectedResultsTextBox viene compilato in modo diverso a seconda del tipo di nodo. Nella maggior parte dei casi viene utilizzata la stringa riconosciuta, ma per InkWord viene utilizzata la stringa riconosciuta della riga e la parola viene selezionata in TextBox.
