在JTable Netbeans中插入Radiobuttons [英] Insert Radiobuttons in JTable Netbeans

问题描述

我使用Netbeans在JTable中填充员工数据。我想在每一行中添加Radiobutton，以便用户可以选择任何行并执行更新/删除等操作。
这是我的TableModel代码：

I am populating Employee Data in JTable using Netbeans. I want to add Radiobutton in each row, so that user can select any row and can perform actions like Update/Delete,etc. Here is my code for TableModel:

    DefaultTableModel model = new DefaultTableModel();

    model.setColumnIdentifiers(new String[] {"Select","Employee ID","Name","Surname","Birth Place","Genre","Home","Marital Status","Phone","Age","Department"});
    try{
    con = DriverManager.getConnection ("jdbc:mysql://localhost:3306/"+database,"root","123456");
    Statement s = con.createStatement ();
    s.executeQuery ("SELECT * FROM Employee");
    ResultSet rs = s.getResultSet ();
    rs.next ();
    String eid = rs.getString ("emp_no");
    String name = rs.getString ("name");
    String surname = rs.getString ("surname");
    String pbirth = rs.getString ("place_birth");
    String genre = rs.getString ("genre");
    String home = rs.getString ("home");
    String mstatus = rs.getString ("marital_status");
    String ph = rs.getString ("phone");
    int age = rs.getInt ("age");
    String dept = rs.getString ("department");
    for(int i=0;i<30;i++)
    model.addRow(new Object[] {?,eid, name, surname, pbirth, genre, home, mstatus, ph, age, dept});
    }
    catch (Exception e){

    }
    this.jTable1.setModel(model);

在每行的第一列中，我想插入一个单选按钮。请建议我。
谢谢。

In first column of every row i want to insert a radiobutton. Please suggest me. thanks.

推荐答案

你必须实现 TableCellEditor 并覆盖 getTableCellEditorComponent ，就像这样

You have to implement TableCellEditor and override getTableCellEditorComponent like this

public java.awt.Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column)

{
            return new JRadioButton();
}

希望这会有所帮助

编辑：
您可以这样写

You can write like this

this.jTable1.getColumnModel().getColumn(0).setCellEditor(new javax.swing.table.TableCellEditor(){
    @Override
    public java.awt.Component getTableCellEditorComponent(javax.swing.JTable table, java.lang.Object value, boolean isSelected, int row, int column) {
        return new javax.swing.JRadioButton();
    }

    @Override
    public java.lang.Object getCellEditorValue() {
return null;//Here you can return the radio button status
    }

    @Override
    public boolean isCellEditable(java.util.EventObject anEvent) {
        return false; //uneditable cell
    }

    @Override
    public boolean shouldSelectCell(java.util.EventObject anEvent) {
        return false;
    }

    @Override
    public boolean stopCellEditing() {
        return true;
    }

    @Override
    public void cancelCellEditing() {       
    }

    @Override
    public void addCellEditorListener(javax.swing.event.CellEditorListener l) {
    }

    @Override
    public void removeCellEditorListener(javax.swing.event.CellEditorListener l) {
    }

});

您可以将单元格编辑器实现取出到单独的类中。

You can take out the cell editor implementation to a separate class.

此外，您必须根据您的要求设置标志。

Also you have to set the flags accordingly to your requirement.
