THintWindow.ActivateHintData procedure
An alternate version of ActivateHint with additional data used for the hint display.
Declaration
procedure ActivateHintData(ARect: TRect; const AHint: string;
AData: pointer); virtualArguments
ARect | Display rectangle for the hint text. |
AHint | Text displayed in the hint window. |
AData | Pointer to additional data used to construct the hint text. |
Description
ActivateHintData is an alternate version of
ActivateHint.
It provides the additional
AData argument which contains a pointer
to values which can be used to construct the text displayed in the hint window.
ActivateHintData stores the value in ARect to the HintRect for the hint window. It ensures that the display rectangle fits within the work area for the monitor where the hint window is displayed. Values in HintRect are adjusted as needed to position and size the window before the hint window becomes visible. ActivateHint is called to display the window with the specified hint text.
THintWindow does not use the
value in AData. The method must be overridden in a descendent class
to use the additional hint data in the AData argument.
