Ejemplos

En el ejemplo siguiente, se muestra cómo se utiliza la propiedad Type de un objeto ContextNodeBase denominado selectedNode. El texto de un objeto TextBox, selectedResultsTextBox, se rellena de manera diferente dependiendo del tipo de nodo. En la mayoría de los casos, se utiliza la cadena reconocida, pero para InkWord, se utiliza la cadena reconocida de la línea, y la palabra se selecciona en TextBox.
