Ejemplos

En el siguiente ejemplo de código se cambia NodeFont el tamaño de al tamaño especificado y se ItemHeight ajusta el del control principal TreeView del nodo de árbol.The following code example changes the size of NodeFont to the specified size and adjusts the ItemHeight of the tree node's parent TreeView control. Este ejemplo requiere Form que tenga un con un TreeView control que contenga una colección de TreeNode objetos y una ComboBox que contenga tamaños de fuente.This example requires that you have a Form with a TreeView control that contains a collection of TreeNode objects, and a ComboBox that contains font sizes.

Comentarios

Si nulles, Font el utilizado es Font TreeView el valor de propiedad del control al que está asociado este nodo.If null, the Font used is the Font property value of the TreeView control that this node is attached to.

Nota

Si la fuente del nodo es mayor que Font el valor de propiedad que se establece TreeView en el control, se recorta el texto de la etiqueta del nodo de árbol.If the node font is larger than the Font property value that is set in the TreeView control, the tree node label text is clipped.
