| 5 | 5 | Jednoduchý (a veľmi krátky) návod: | |
| 6 | 6 | ||
| 7 | 7 | 1\. Umiestnite ikonku SaveDialog na váš formulár (hocikam, lebo za behu programu sa aj tak nezobrazí). | |

| 11 | + | (Je to druhá najlavejšia ikonka v záložke Dialogs) | |
| 12 | + | ``` | |
| 11 | 13 | ||
| 12 | 14 | 2\. Pridajte do formulára komponentu Memo. | |
| 13 | 15 | ||
| 14 | 16 |  | |
| 15 | 17 | ||
| 16 | 18 | 3\. Pridajte do formulára tlačidlo. | |
| 17 | 19 | ||
| 18 | 20 |  | |
| 19 | 21 | ||
| 20 | 22 | V okne [[IDE Window: Object Inspector|Object Inspector]] sa zobrazi vlastnosti objektu Button1. Nastavte vlastnosť 'Caption' na 'Save'. Kliknite na záložku Events (udalosti) v okne Object Inspector. Kliknite na malý obdĺžniček napravo od 'OnClick', automaticky sa prenesiete do editoru kódu (Source Editor) s automaticky vytvoreným kúskom kódu. Vložte: | |
| 21 | 23 | ||
| 22 | 24 | ``` pascal | |
| 23 | 25 | procedure TForm1.Button1Click( Sender: TObject ); | |
| 24 | 26 | begin | |
| 25 | 27 | if SaveDialog1.Execute then | |
| 26 | 28 | Memo1.Lines.SaveToFile( SaveDialog1.Filename ); | |
| 27 | 29 | end; | |
| 28 | 30 | ``` | |
| 29 | 31 | ||
| 30 | 32 | Metóda [[doc:lcl/dialogs/tcommondialog.execute.html|Execute]] zobrazí dialógové okno Uložiť súbor. Vráti true, ak užívateľ vyberie súbor, alebo false, ak okno stornuje. | |
| 31 | 33 | ||
| 32 | 34 | Vlastnosť [[doc:lcl/dialogs/tfiledialog.filename.html|Filename]] potom obsahuje názov súboru, vrátane disku a celej cesty. | |
