| 2 | + | ||
| 3 | + | 1\. Umiestnite ikonku OpenDialog na váš formulár (hocikam, nakoľko za behu programu je aj tak neviditeľná). | |
| 4 | + | ||
| 5 | + | ` `\ | |
| 6 | + | ` `\ | |
| 7 | + | ` (Je to tá najlavejšia ikonka v paneli Dialogs)` | |
| 8 | + | ||
| 9 | + | 2\. Do vašeho kódu umiestnite niečo takéto: | |
| 10 | + | ||
| 11 | + | ``` pascal | |
| 12 | + | var filename : string; | |
| 13 | + | ||
| 14 | + | if OpenDialog1.Execute then | |
| 15 | + | begin | |
| 16 | + | filename := OpenDialog1.Filename; | |
| 17 | + | ShowMessage(filename); | |
| 18 | + | end; | |
| 19 | + | ``` | |
| 20 | + | ||
| 21 | + | 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. | |
