What can the DrawGrid component display at the same time?

Question

Delphi

Please provide correct answers. There is an assumption that only drawings ...

Answer 1

This component allows you to display everything that can be drawn programmatically: pictures, texts, lists, formulas, and so on. The form is not only drawing, but also the placement of an object with its window handle, so that disappears. "Calculations" is too general a term, but if you can figure out how to draw a diagram/formula of calculations, then you are welcome. And the rest rolls.

Answer 2

The form... is dropped.

A form can be "embedded" using Parent .
For example (FilmDatailFM "embeddable" form):

...
    tsDatail: TTabSheet;
...
procedure TMainFM.tsDatailShow(Sender: TObject);
begin
  if FilmDatailFM = nil then begin
    FilmDatailFM := TFilmDatailFM.Create( Application );
    FilmDatailFM.Parent := tsDatail;
  end;
  FilmDatailFM.Show;
end;
