TFileDialog.IntfFileTypeChanged procedure
Signals the OnTypeChange event handler when the value in FilterIndex is changed by the widgetset class instance.
Declaration
procedure IntfFileTypeChanged(NewFilterIndex: Integer)Arguments
NewFilterIndex | New value for the FilterIndex property. |
Description
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.
