(* Always on Top *)
{I had a hard time finding out how to ensure a form always remains on top
of all other forms. fsAlwaysOnTop only affects the z-order within the
current application. To ensure that it remains on top of other forms from
other programs as well, one needs to use the Windows API.
Including the following in a form's OnCreate event will designate it as a
topmost window.}
procedure TYourForm.FormCreate(Sender: TObject);
begin
SetWindowPos(YourForm.Handle,
HWND_TOPMOST,
0, 0, 0, 0,
SWP_NOMOVE OR
SWP_NOACTIVATE OR
SWP_NOSIZE);
end;
{However, you need to keep reminding Windows to restore your window to the
top of the z-order ahead of any other topmost windows by adding the
following to the form's OnPaint event. Otherwise, other programs that
modify the z-order can paint over yours.}
procedure TYourForm.FormPaint(Sender: TObject);
begin
SetZOrder(True);
end;
