IsDirectoryEmpty Event

Fires when the OS needs to know whether a directory is empty.

Syntax

type TIsDirectoryEmptyEvent = procedure (
  Sender: TObject;
  const DirectoryName: String;
  var IsEmpty: Boolean;
  var DirectoryContext: Pointer;
  var ResultCode: Integer
) of Object;

property OnIsDirectoryEmpty: TIsDirectoryEmptyEvent read FOnIsDirectoryEmpty write FOnIsDirectoryEmpty;

Remarks

This event fires when the OS needs to know whether the directory specified by DirectoryName is empty.

This event only needs to be handled if the UseDirectoryEmptyCheck property is enabled. To handle this event properly, applications must set the IsEmpty parameter appropriately.

The DirectoryContext parameter is a placeholder for application-defined data associated with the directory (for "general-purpose" events, it is called FileContext instead). Please refer to the Contexts topic for more information.

The ResultCode parameter will always be 0 when the event is fired. If the event cannot be handled in a "successful" manner for some reason (e.g., a resource isn't available, security checks failed, etc.), set it to a non-zero value to report an appropriate error. Please refer to the Error Reporting and Handling topic for more information.
