| 8 | + | Jednoduchý (a veľmi krátky) návod: | |
| 9 | + | ||
| 10 | + | 1\. Umiestnite ikonku SaveDialog na váš formulár (hocikam, lebo za behu programu sa aj tak nezobrazí). | |
| 11 | + | ||
| 12 | + | ` `\ | |
| 13 | + | ` (Je to druhá najlavejšia ikonka v záložke Dialogs)` | |
| 14 | + | ||
| 15 | + | 2\. Pridajte do formulára komponentu Memo. | |
| 16 | + | ||
| 17 | + | <figure> | |
| 18 | + | <img src="tmemo.png" title="tmemo.png" /> | |
| 19 | + | <figcaption>tmemo.png</figcaption> | |
| 20 | + | </figure> | |
| 21 | + | ||
| 22 | + | 3\. Pridajte do formulára tlačidlo. | |
| 23 | + | ||
| 24 | + | <figure> | |
| 25 | + | <img src="tbutton.png" title="tbutton.png" /> | |
| 26 | + | <figcaption>tbutton.png</figcaption> | |
| 27 | + | </figure> | |
| 28 | + | ||
| 29 | + | 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: | |
| 30 | + | ||
| 31 | + | ``` pascal | |
| 32 | + | procedure TForm1.Button1Click( Sender: TObject ); | |
| 33 | + | begin | |
| 34 | + | if SaveDialog1.Execute then | |
| 35 | + | Memo1.Lines.SaveToFile( SaveDialog1.Filename ); | |
| 36 | + | end; | |
| 37 | + | ``` | |
| 38 | + | ||
| 39 | + | Metóda [[doc:lcl/dialogs/tcommondialog.execute.html|Execute]] zobrazí dialógové okno Uložiť súbor. Vráti true, ak užívateľ vyberie súbor, alebo false, ak okno stornuje. | |
| 40 | + | ||
| 41 | + | Vlastnosť [[doc:lcl/dialogs/tfiledialog.filename.html|Filename]] potom obsahuje názov súboru, vrátane disku a celej cesty. | |
