THintWindow.ActivateHintData Method
|
RAD Studio VCL Reference
|
|
|
Displays the hint window using a provided data value.
procedure ActivateHintData(Rect: TRect; const AHint: string; AData: TCustomData); virtual;
virtual __fastcall ActivateHintData(TRect Rect, const AnsiString AHint, TCustomData AData);
Call ActivateHintData to display the hint window at the coordinates provided by the Rect parameter. The ActivateHintData method for THintWindow sets the Caption property to the AHint parameter and ignores the AData parameter. Descendant classes can override this method to combine the AHint and AData parameters into a customized Hint value.
After an application displays a hint window, it automatically deactivates it after a time period has elapsed, or when it receives a message that requires hiding the hint message. To hide the hint window that is brought up automatically by the application, use the HideHint method of the global Application object. To hide a hint window that is activated directly by calling ActivateHint, use the ReleaseHandle method.
