Title: As/es
| Old | New | Line | |
|---|---|---|---|
| 1 | + | ## As | |
| 2 | + | ||
| 3 | + | La palabra reservada **As** pertenece a la programación orientada a objetos y se utiliza para convertir (TypeCast) un objeto en una clase. Para ello, el objeto debe ser una instancia de la clase. | |
| 4 | + | ||
| 5 | + | Ejemplo: | |
| 6 | + | ||
| 7 | + | ``` pascal | |
| 8 | + | procedure TmainForm.selectionGridDrawColumnCell(Sender: TObject; const Rect: TRect; DataCol: Integer; Column: TColumn; State: TGridDrawState); | |
| 9 | + | begin | |
| 10 | + | (Sender As TDBGrid).DefaultDrawColumnCell(Rect,DataCol,Column,State); | |
| 11 | + | end; | |
| 12 | + | ``` | |
| 13 | + | ||
| 14 | + | Aquí la variable Sender del tipo (type of) TObject se convierte/asigna como (**as**) tipo (type) TDBGrid. | |
