TCustomFileListBox.OnChange property
Event handler signalled when the selected file in the list box control is changed.
Declaration
property OnChange: TNotifyEvent read FOnChange write FOnChange;Description
OnChange is a
TNotifyEvent property which contains the
event handler signalled when the selected file for the control has been
changed. This can occur when clicking on an entry in list box, when assigning
a value directly to the
FileName property, and when the list of
file system entries in the control is reloaded.
OnChange is triggered (when assigned) from the DoChangeFile
method. An application must implement and assign an object procedure to the
handler to respond to the event notification.
