将CheckBox添加到jTable? [英] Add CheckBox to jTable?

问题描述

我需要在行中添加一个复选框，但是我不知道该怎么做.

I need to add a checkbox the rows, but I don't know how to do that.

我正在使用自己在互联网上获得的表模型.

I'm using an own Table Model that I got on internet.

表模型的代码:

import java.util.ArrayList;
import javax.swing.table.AbstractTableModel;
/**************/

public class ModeloTabela extends AbstractTableModel {
    private ArrayList linhas = null;
    private String [] colunas = null;

    public ModeloTabela(ArrayList lin, String[] col){
        setLinhas(lin);
        setColunas(col);
    }
    public ArrayList getLinhas(){
        return linhas;

    }
    public void setLinhas(ArrayList dados){
        linhas = dados;
    }
    public String[] getColunas(){
        return colunas;
    }
    public void setColunas(String [] nomes){
        colunas = nomes;
    }
    public int getColumnCount(){
        return colunas.length;
    }
    public int getRowCount(){
        return linhas.size();
    }
    public String getColumnCount (int numCol){
        return colunas[numCol];
    }

    public Object getValueAt(int numLin, int numCol){
        Object[] linha = (Object[])getLinhas().get(numLin);
        return linha[numCol];
    }

此方法将填充表格:

public void PreencheTabela(String sql, JTable jt1, JTextField j1){
        c.conexao();
        ArrayList dados = new ArrayList();

        String [] Colunas = new String[] {"STATUS", "ID", "FABRICANTE", "FORNECEDOR", "NOME", "CATEGORIA", "DATA DO CADASTRO", " CODIGO DE BARRAS", "QUANTIDADE"};

        c.executaSQL(sql);
        try { 
            c.rs.first();
            do{
            dados.add(new Object[]{c.rs.getInt("prod_id"),c.rs.getString("prod_fabricante"),c.rs.getString("prod_fornecedor"),c.rs.getString("prod_nome"),
                c.rs.getString("prod_categoria"),c.rs.getDate("prod_datacadastro"),c.rs.getString("prod_codbarras"), c.rs.getInt("est_quantidade")});
            j1.setBorder(BorderFactory.createLineBorder(Color.black));
        }while(c.rs.next());

        } catch (SQLException ex) {
            JOptionPane.showMessageDialog(null, "Erro!\n"+ex.getMessage());
        }
        ModeloTabela modelo = new ModeloTabela(dados, Colunas);
        jt1.setModel(modelo);
}

我可以使用哪个代码?该代码放在哪里?

Which code can I use? Where do I put this code??

推荐答案

您需要在TableModel中实现getColumnClass(int columnIndex)，并确保它为要包含复选框的列返回Boolean.

you need to implement getColumnClass(int columnIndex) in your TableModel, and make sure it will return Boolean for the column you want to contain checkboxes.

看一下本指南，它非常有用: http://docs.oracle.com/javase/tutorial/uiswing /components/table.html#data
