Oi gente,
Duvida - Como transformar uma imagem para o jLabel, sem usar macetes do Netbeans?

Minha dúvida é a seguinte, Eu tenho que pegar uma imagem em um local X , e colcoar em um Jlabel que esta em um jFrame!

Eu preciso conseguir mudar de imagem quando puder. As imagens poderão estar em JPEg eu acho.

Olhei o javadoc mas não entendi nada.Alguém pode me ajudar? Pelo menos indicar o que devo fazer ou que pesquisar ? Só uma luz plx

Valeu gente.

ImageIcon imagem = new ImageIcon(file); suaLabel.setIcon(imagem);

Onde file é o File da imagem (que vocêp pode obter por um JFileChooser).

Se quiser mais flexibilidade que isso, use um ImagePanel:

ViniGodoy:
ImageIcon imagem = new ImageIcon(file);
suaLabel.setIcon(imagem);

Onde file é o File da imagem (que vocêp pode obter por um JFileChooser).

Se quiser mais flexibilidade que isso, use um ImagePanel:

Valeu Viny, mas ainda tenho uma dúvida. Em javaFX , quando eu fiz algo parecido com isso, tive que fazer uns esquemas pra ele transformar a String em URI e depois em URL.
Aqui, eu nao queria usar o JFileChooser, ja queria jogar o caminho direto , por exemplo : "C:\foto.jpeg"

public static void setImageInLabel(String file)
{
     //pega a string e faz algo?
    
    //Seta a "file" como imageicon
        ImageIcon imagem = new ImageIcon(file);  
        jLabel_FotoAeronave.setIcon(imagem);  
}
Eu jogaria esse "C:\foto.jpeg" como parametro e o método faria o resto.

Como poderia fazer isso ?

Valeu pela resposta

Mas é JavaFX ou Swing?

Em Swing, bastaria fazer:

Java Swing.Ainda preciso de ajuda :? ...

Tentei com jFileChooser, passei pra URI, depois pra URL, depois pra STRING. até que funcionou, mas a iamgem nao é mostrada. Em compensação, nao da erro,
usei revalidate() tbm e nao foi.

Viny, fiz o que vc falou:

Está faltando um pouco de conceito básico de OO aí.

Para começar, não declare coisas como "static". Se você fizer isso, elas pertencerão à classe AeronaveNaTela, não somente ao objeto da tela em si.

SirDominque

Viny, obrigado pela ajuda de novo. mas nao deu certo.
Tentei do seu modo, coloquei tudo certinho. Copiei a classe da interface, coloquei na classe java, pq o lixo do netbeans n deixa copiar e etc..
Enfim, nao deu.

Fiz algumas modificações com SYSTEm.out pra saber se o método esta sendo chamado. E foi isso a resposta:

run: passo 0 passo 2 passo 3 passo 1 CONSTRUÍDO COM SUCESSO (tempo total: 5 segundos)

A imagem ainda nao é exibida.
depois disso, tentei passar a string pra uri, url e depois pra string de novo, pra ver se ia, mas nao foi.

Segue o Código novamente :
A classe main, permanece igual.ok?

<blockquote>public void setImageInLabel()

{

System.out.println(“passo 2”);

String file =  “C:\foto.jpeg”;

ImageIcon imagem = new ImageIcon(file);   
jLabel_FotoAeronave.setIcon(imagem);  
//jLabel_FotoAeronave.revalidate();
//jLabel_FotoAeronave.validate();
System.out.println("passo 3");

}
}

Modifiquei esse método várias vezes, mudei algumas coisas, mas nao adiantou.
