[Lazarus] how to get Type of Sender or Components[i] in order to Cast?

[Péter Gábor]

If you typecast something you can use the fields and properties of the
type you use for casting, for example:

if TCheckBox(Sender).Checked then {do_something}  ;

or

if TCheckBox(Components[I]).Checked then {do_something}  ;
