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

Assuntos Gerais
#1

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.

#2

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:

#3

[quote=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:
https://github.com/MarkyVasconcelos/Towel/blob/master/src/com/towel/swing/img/JImagePanel.java[/quote]

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”

[code]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);

}
[/code]
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:

#5

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.

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:

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

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?
