I saw the Qt code, but don't know how to do this in GTK.

My intention was to create a placeholder without working in methods
RealGetText/RealSetText. In Windows I can easily do with:

(...)
const
  ECM_FIRST = $1500;
  EM_SETCUEBANNER = ECM_FIRST + 1;
begin
  Edit1.Perform(EM_SETCUEBANNER, 0, LParam(PWideChar(WideString('Test'))));
end;
(...)

I gave up trying to do in GTK, with canvas. x(

Thanks to all.
