Chamar uma função dentro de um Jframe

Willdoidao · Junho 25, 2009, 1:43pm

Sei que para quem conheçe e entende é uma pergunta idiota, mas estou a alguns dias já estudando e todos os exemplos q acho são pra quem fez tudo na mal fiz uma tela no netbeans usando as ferramentas visuais e os exeplos q achei aqui no forum e no google foram todos pra quem fez a mão ou nw funcionaram pra mim a tela q criei foi essa:

[code]package camera;

Alguem podeia me ajudar, explicar e me indicar algum mateiral. desde já agradeço a atenção!

Tela tela = new Tela();
tela.nomeDaFuncao();

Willdoidao · Junho 25, 2009, 2:10pm

Cara Desculpa a ignorancia, mas aonde faço isso, quando estou iniciando tudo?

gregorioarthur · Junho 25, 2009, 2:20pm

ou se vc quiser criar um botão pra chamar esse método, pode por um actionListener()

=D

vitinho1712 · Junho 25, 2009, 2:22pm

não, vc faz isso quando for usar a função, vou te explicar pra ficar mais fácil

na primeira linha vc está criando o objeto que contém a função,
na segunda vc está chamando a função que está nesse objeto

entendeu ?

Willdoidao · Junho 25, 2009, 3:05pm

Caras realmente me desculpa,mas tá dificil eu entendi o que vc explicou Vitinho mas ainda nw achei aonde seria q colocaria isso, seria aqui:

[code]public class Frontend extends javax.swing.JFrame {

/** Creates new form Frontend */
public Frontend() {
    initComponents();
    Teste1 teste1 = new Teste1();
     
    
                Visor tela = new Visor();
                
                tela.teste1(); 

     }[/code]

Só q dá dando erro e pedindo pra criar outra função!

vitinho1712 · Junho 25, 2009, 9:44pm

vc fez o import da tela que tá a função ?

Willdoidao · Junho 25, 2009, 10:36pm

Sim fiz sim, olhando o primeiro código lá em cima é o 3 ou 4 import q fiz!

vitinho1712 · Junho 26, 2009, 6:31am

A função que vc quer tá no Teste1 ou no Visor ?
Esta função foi declarada como public ?
