| 1 | 1 | Jednoduchý (a veľmi krátky) návod: | |
| 2 | 2 | ||
| 3 | 3 | 1\. Umiestnite ikonku OpenDialog na váš formulár (hocikam, nakoľko za behu programu je aj tak neviditeľná). | |

| 7 | + | ||
| 8 | + | (Je to tá najlavejšia ikonka v paneli Dialogs) | |
| 9 | + | ``` | |
| 8 | 10 | ||
| 9 | 11 | 2\. Do vašeho kódu umiestnite niečo takéto: | |
| 10 | 12 | ||
| 11 | 13 | ``` pascal | |
| 12 | 14 | var filename : string; | |
| 13 | 15 | ||
| 14 | 16 | if OpenDialog1.Execute then | |
| 15 | 17 | begin | |
| 16 | 18 | filename := OpenDialog1.Filename; | |
| 17 | 19 | ShowMessage(filename); | |
| 18 | 20 | end; | |
| 19 | 21 | ``` | |
| 20 | 22 | ||
| 21 | 23 | Metóda [[doc:lcl/dialogs/tcommondialog.execute.html|Execute]] zobrazí dialógové okno "Otvor súbor". Vráti true ak užívateľ vybral nejaký súbor, alebo false ak užívateľ okno zrušil. Vlastnosť [[doc:lcl/dialogs/tfiledialog.filename.html|Filename]] potom obsahuje celý názov súboru, vrátane disku a kompletnej cesty. | |
