Beispiele

Im folgenden Codebeispiel wird die Größe NodeFont in die angegebene Größe geändert und das ItemHeight übergeordnete TreeView Steuerelement des Strukturknotens angepasst. Dieses Beispiel erfordert, dass Sie über ein FormTreeView Steuerelement mit einer Auflistung von TreeNode Objekten und einem ComboBox Steuerelement verfügen, das Schriftgrade enthält.

private:
   void Button1_Click( Object^ /*sender*/, EventArgs^ /*e*/ )

      // Get the font size from combobox.
