TFileDialog.DefaultExt property

Declaration

property DefaultExt: string read FDefaultExt write SetDefaultExt;

Description

DefaultExt is a String property which contains the default file extension used for the FileName or Files in the file dialog. It can contain a value like 'pas' or '.pas'. If the Period character is not present in the first position, it is inserted before the property value is stored.

DefaultExt is used in descendent classes, like TOpenDialog, and provides the value that is appended to a file name when an extension or a Filter has not been provided.
