java:如何只选择一个jtable中的一个单元格而不是整个行 [英] java: how to select only one cell in a jtable and not the whole row

问题描述

在jTable中，我希望当用户单击一个单元格时，将这句话打印在屏幕上:

in a jTable, I want when a user clicks on a cell, this sentence to be printed on the screen :

I am cell in row X and column Y

其中x和Y是单击的单元格的行和列. 但是我得到的是:例如，当我单击第1行和第4列中的单元格时 我得到以下信息:

where x and Y are the row and column of the clicked cell. But what I am getting is : when I click for example the cell in row 1 and column 4 I get the following :

I am cell in row 1 and column 0
I am cell in row 1 and column 1
I am cell in row 1 and column 2
....
I am cell in row 1 and column N  ( N = number of columns)

即整个行都被选中.

这是代码:

public class CustomTableCellRenderer extends DefaultTableCellRenderer{

public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
{

    Component cell = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);

            if(isSelected) System.out.println("I am cell in row "+row+" and column "+column);



    return cell;

}

}

感谢您的帮助.

推荐答案

CellRenderers用于呈现单元格内容.如果要查找单击鼠标所在的单元格，请使用MouseListener并在mouseClicked方法中找到该单元格.

CellRenderers are used for rendering the cell contents. If you want to find the cell in which the mouse clicked, use a MouseListener and in the mouseClicked method find the cell.
