Prohlizec obrazku – Java – Fórum – Programujte.com

Zdravim, resim mensi problem, se kterym si nevim rady.Ten problem jsou tlacitka Predchozi a dalsi. Nactu nejaky obrazek ze slozky. Slozku ulozim do promene, a necham si vypsat vsechny veci te slozky do pole. A ted potrebuju abych podle jmena zjistil, ktere cislo se rovna tomu memu obrazku, a pri kliku na dalsi se zvetsilo, atd. Uryvek kodu.

public static String adresar;

public static String pname;



otevrit.addActionListener(new ActionListener(){

			public void actionPerformed(ActionEvent evt){

				FileDialog open = new FileDialog(frame,"Zvolte soubor....",FileDialog.LOAD);

				String openFile,kudy;

				

				open.show();

				

				if((openFile = open.getFile()) != null){

					adresar = open.getDirectory();

					pname = open.getFile();

					kudy = adresar+pname;

					

					obrazek.setIcon(new ImageIcon(kudy));

					cesta.setText(kudy);

					

				}

				

			}

		});



		predchozi.addActionListener(new ActionListener(){

			public void actionPerformed(ActionEvent evt) {

				File slozka = new File(adresar);

				File [] c = slozka.listFiles();

				int i;

				

				for(i=0; i < c.length;i++){

					//tady by seemelo zjistit, ktere cislo(i) = tomu obrazku

					

				}

				

			}

		});

Neviem ci som to dobre pochopil, ale ty chces priradit kazdemu obrazku nejake cislo a potom sa pomocou toho cisla presuvat medzi obrazkami?

jj, zatim me lepsi reseni nenapadlo..

Dalo by sa to spravit asi aj podla indexov pola, ale na presuvanie medzi prvkami nejakeho zoznamu su urcene kolekcie. Zopar linkov:
