MouseEvent

[Fernando hiar]

I´m creating a program who is loaded in JPanel superior the images and when the user click in an imagem this image appear in Jpanel inferior...

there´s the code of Janela1(Window1)

package Codigo;

import javax.swing.*;
import java.awt.event.*;
import java.awt.*;


public class Janela1 extends JFrame {
	int pWidth, pHeight;
	CarregarImagens imagens;
	int posX;
	int posY;
	int y1[] = {50,50,50,50,50,50,50,150,150,150,150,150,150,150,250,250,250,250,250,250,250};
	Image nome3[] = new Image[21];
	PintarImagem pi;
	EventImagem ei;
	JPanel inferior,superior;
	
	public Janela1(int x, int y, CarregarImagens ci) {
		
		pWidth =x;
		pHeight = y;
		imagens = ci;
			
		
		Container c = getContentPane();
		c.setLayout(null);
		
		setBackground(Color.white);
		setVisible(true);
		setSize(pWidth,pHeight);
		setResizable(true);
		

		superior = new PintarImagem(pWidth,pHeight,imagens);
		c.add(superior);
		superior.setBounds(-30,-30,pWidth,pHeight-200);
		//Aqui aonde estão as imagens que serão clicadas pelo mouse
		
		JLabel rotulo1 = new JLabel("");
		rotulo1.setIcon(getImagem("00021.gif"));
		rotulo1.setBounds(50,pHeight-240,90,90);
		
		JLabel rotulo2 = new JLabel("");
		rotulo2.setIcon(getImagem("00031.gif"));
		rotulo2.setBounds(150,pHeight-240,90,90);
		
		JLabel rotulo3 = new JLabel("");
		rotulo3.setIcon(getImagem("00111.gif"));
		rotulo3.setBounds(620,pHeight-240,90,90);
		c.add(rotulo1);
		c.add(rotulo2);
		c.add(rotulo3);
		
		inferior = new EventImagem(pWidth,pHeight,imagens);
		c.add(inferior);
		inferior.setBounds(50,pHeight-150,90,90);
		//aqui aonde eu pintaria as imagens que foi clicado no JPanel superior
		
		addMouseListener(new Tratador());
		
	}
	public ImageIcon getImagem(String nome){   
        String caminhoDaImagem = "/Imagens2/" + nome;   
        ClassLoader classLoader = this.getClass().getClassLoader();   
        ImageIcon icone = new ImageIcon(getClass().getResource(caminhoDaImagem)); 
        return icone;   
    }  
	
	public  class Tratador extends MouseAdapter {
		
		public void mousePressed(MouseEvent e) { 
			String s;// --ö)
			posX = e.getX();
			posY = e.getY();
			EventImagem.passarMouse(posX, posY);
			repaint();
			
		}
	}
}

there´s the code of the two JPanel superior and inferior who the classes is : PintarImagem and EventImagem...there´s the 2 classes:

PintarImagem(JPanel superior):

package Codigo;


import javax.swing.*;
import java.awt.*;
import java.io.IOException;

public class PintarImagem extends JPanel {
	Image nome2[] = new Image[21];
	CarregarImagens ima;
	static int x1[] = new int[21];
	static int y1[] = new int[21];
    int pWidth, pHeight;
    static int posX,posY;
    static boolean passou2;
	public PintarImagem(int w, int h, CarregarImagens c) {
		ima = c;
		pWidth = w;
		pHeight = h;
		setImage();
	}
		
		public void setImage() {
			String s;
			for(int i = 0; i <= 20; i++) {
				s = (String)ima.id.get(i);
				nome2[i] = ima.getImage(s, i);
			}
		}
		
		protected void paintComponent(Graphics g) { 
 			 super.paintComponent(g);
 			 int x =50, y = 50; 
 			 
 			for(int i = 0; i <= 20; i++) {
				if(x > pWidth - 100) {
					y = y + 100;
					x = 50;
					x1[i] = x;
					y1[i] = y;
				}		
				try { 
					g.drawImage(nome2[i], x,y,this);
					x1[i] = x;	
					x = x + 100;
				}
				catch(Exception e) {
				e.printStackTrace();
				}		
			}
 			
 		}
		
		
}	

and EventImagem:

package Codigo;

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class EventImagem extends JPanel  {
	static int posX;
	static int posY;
	int y1[] = {50,50,50,50,50,50,50,150,150,150,150,150,150,150,250,250,250,250,250,250,250};
	static Image[] nome3 = new Image[21]; 
	PintarImagem pi;
	int pWidth, pHeight;
	CarregarImagens imagens2;
	static String s = "";

	
	public EventImagem(int x,int y,CarregarImagens imagens) {
		pWidth =x;
		pHeight = y;
		imagens2 = imagens;
	}
	
	public static void passarMouse(int x1, int x2) {
		posX = x1;
		posY = x2;
	}
	

	protected void paintComponent(Graphics g) {
		super.paintComponent(g);
		int x = 50;
		for(int i = 0; i <=20;i++) {
			if(((posX >= pi.x1[i])&&(posX <= pi.x1[i]+ 90))&&
					((posY >= y1[i])&&(posY <= y1[i] + 90))) {
					//coordenadas x ja são existentes
					try {	
					s = (String)imagens2.id.get(i);
					nome3[i] = imagens2.getImage(s, i);	
					g.drawImage(nome3[i],x,pHeight-150,this);
					x = x + 100;
					}
					catch(Exception e) {
						e.printStackTrace();
					}
			}		
		}
	}
}

the issues is: when I call the Mouse event, the event call paintComponent of EventImagem class load the imagem of this method, but don´t paint the image in JPanle inferior, the question is Why? I debugged this code and I see, first the jvm call paintComponent of EventImagem and after the jvm call paintComponent of PintarImagem.... I don´t know what´s happening......

thanks,

Nothing wrong in posting code in a language
few here can interpret.

In doing so, it is critical that the code must
compile and/or run with java error messages that gives us a clue to the problem.

'cannot find class ...' as an error message
is just wasting everyone's time.

There´s no error of compilation, but the image doesn´t appear in the event..... I thought there´s an error of logic or the language....I don´t know....

Someone with 3690 posts doesn't make a silly statement. Can you compile the three classes you posted, in isolation?

Hint: you can't. Try it, discover why, then post code that people can actually help you with, preferably in the form of an SSCCE <--click the link.
