NewFilterIndex |

New value for the FilterIndex property. |
IntfFileTypeChanged is a callback routine used by the widgetset class when it applies a change to the value in the FilterIndex property. It occurs when the FilterIndex returned from the native dialog is handled by the widget.
IntfFileTypeChanged stores the value in NewFilterIndex to its internal member, and calls DoTypeChange to signal the OnTypeChange event handler (when assigned).
Use the OnTypeChange event handler to perform actions needed when the value in FilterIndex has been modified.
