开始编辑JTable Cell时选择所有数据 [英] Select all data when start editing JTable Cell

问题描述

我正在尝试创建一个像Excel一样工作的表。这意味着，当用户开始将数据插入单元格时，内容将被选中并通过插入的新数据进行更改。

I'm trying to make a table that works like Excel. Meaning, when a user starts to insert data into the cells the content into them is selected and changed by the new data inserted.

推荐答案

您可以为表创建自定义TableCellEditor。这个类将有一个 TextField 的实例变量，让我们称之为 textField 。然后 getTableCellEditorComponent 方法可能如下所示：

You can create a custom TableCellEditor for your table. This class will have an instance variable of a TextField, lets call it textField. Then the getTableCellEditorComponent method could look like this:

public Component getTableCellEditorComponent(JTable table, Object value, 
                             boolean isSelected, int row, int column ) {
    textField.setText(value.toString());
    textField.selectAll();
    return textField;
}
