TCustomForm.OnCloseQuery property

Declaration

property OnCloseQuery: TCloseQueryEvent read FOnCloseQuery write FOnCloseQuery;

Description

OnCloseQuery is a TCloseQueryEvent property which contains the event handler signalled to determine whether the form can be closed. Set the value in the CanClose argument to True to allow the form instance to be closed. The default value for CanClose is True.

Use OnCloseQuery to perform any actions or dialogs needed to confirm that the form can in fact be closed.

An application must implement and assign an object procedure using the signature in TCloseQueryEvent to respond to the event notification.

OnCloseQuery is signalled from the CloseQuery method, and occurs immediately after MDI child forms have called their CloseQuery methods.
