Hi there,
I have three questions:

1. Is it worth (and how to) write my own component a'la TStringGrid, but
derive it directly from TCustomControl?
I believe so -- for sake of saving useless functionality code (like i.e.
fonts etc.) and possibility of introducing own functions that TStringGrid
simply does not support -- but I am not sure...

2. How to make -- in lieu of TInplaceEdit as a descendant from
TCustomMaskEdit -- a brandnew TInplaceEdit as a descendant from TWinControl,
so that on its base I could then build my own TInplaceSimpleEdit (a'la
TMaskEdit), TInplaceCombo (a'la TComboBox), TInplaceCalendar (a'la
TDateTimePicker)? Is my hierarchy alright?
example:
  uses ...; //we do not use the Grids library
  type
    TMyCustomGrid = class(TCustomControl)
    private
      FInplaceEdit: TInplaceEdit;
      ...
    end;
    ...
    TInplaceEdit = class(TWinControl)
    ...
    TInplaceCombo = class(TInplaceEdit)
    ...
    TInplaceSimpleEdit = class(TInplaceEdit)
    ...

3. What is the best way -- in this situation -- to make a column acting like
CheckBox? Also as TInplaceEdit, or in some better way?

Thanks and regards,
Kris
