在J2ME的LWUIT表中自定义单元格的创建 [英] Custom creation of cells in a LWUIT Table in J2ME

问题描述

我正在尝试在我的J2ME应用程序中创建LWUIT表，其中一列中的所有单元格均为特定类型，例如TextField采用十进制输入.

I am trying to create a LWUIT Table in my J2ME application where all cells in one column are of a particular type e.g. TextField taking decimal input.

有人可以建议实现这种方法，或者我可以采取另一种方法吗?

Could anyone please suggest of achieving this or even another approach I could take?

推荐答案

我在错误的区域中寻找.

I was looking in the wrong area.

我没有使用ListCellRenderer，而是扩展了Table对象并覆盖了createCell方法.

Instead of using ListCellRenderer I extended the Table object and overrode the createCell method.

public class CustomTable extends Table{
    public CustomTable(TableModel model) {
        super(model);
    }
    protected Component createCell(Object value, int row, int column, boolean editable) {
        switch (column) {
            case QUANITY_COLUMN:
                // create custom cell and return
                ...
            default:
                return super.createCell(value, row, column, editable);
        }
    }

}
