Question: You might sometimes want to force a hint window to appear. For example, when the mouse enters a certain cell or column of a grid.
Answer:
Thanks to Jonas Juskys
var hintWnd: THintWindow;
procedure TForm1.ActivateHintNOW( x,y: Integer);
var rect: TRect;
begin
HintTxt := 'qq';
if hintTxt '' then
begin
rect := hintWnd.CalcHintRect( Screen.Width, hinttxt, nil);
rect.Left := rect.Left + x;
rect.Right := rect.Right + x;
rect.Top := rect.Top + y;
rect.Bottom := rect.Bottom + y;
hintWnd.ActivateHint( rect, hinttxt);
end;
end;
Note: To hide a hint window that is activated directly by calling ActivateHint, use the ReleaseHandle method.
