java JTable - 显示为复选框的布尔值并且必须是可编辑的

JTable - Boolean to show as check box and must be editable

提问by user1808348

Ok so I have a JTable that I populated from an LinkedHashSet of Books.

好的，所以我有一个从 LinkedHashSet of Books 填充的 JTable。

    public static void LibToArray(){
    rowData = new Object[Book.bookList.size()][5];
    int i = 0;
    Iterator it = Book.bookList.iterator();
    while(it.hasNext()){
        Book book1 = (Book)it.next();
        rowData[i][0] = (Integer)book1.getId();
        rowData[i][1] =  book1.getTitle();
        rowData[i][2] =  book1.getAuthor();
        rowData[i][3] = (Boolean)book1.getIsRead();
        rowData[i][4] =  book1.getDateStamp();
        i++;
        }
    }

My issue Is I want the 4th coloum to show the Boolean status as a check Box, and I want it to be able to be changed, after saving the status back to the LinkedHashSet and refreshing the table.

我的问题是我希望第 4 个 coloum 将布尔状态显示为复选框，并且我希望在将状态保存回 LinkedHashSet 并刷新表后能够对其进行更改。

Sorry I am rather beginner, if you can give me some advice it will be appreciated.

抱歉，我是初学者，如果您能给我一些建议，将不胜感激。

In the table model, in getColumnClass()return Boolean.classfor the particular column. For example for AbstractTableModelor DefaultTableModelextensions:

在表模型中，对于特定列的getColumnClass()回报Boolean.class。例如对于AbstractTableModel或DefaultTableModel扩展：

@Override
public Class<?> getColumnClass(int columnIndex) {
    if (columnIndex == 3)
        return Boolean.class;
    return super.getColumnClass(columnIndex);
}

Also, to make the cell editable, override isCellEditable(), for example:

此外，要使单元格可编辑，请覆盖isCellEditable()，例如：

@Override
public boolean isCellEditable(int row, int col) {
    return (col == 3); 
}
