添加按钮到jtable [英] Adding button to a jtable
问题描述
我有一张桌子，我必须添加一个JButton。
I am having a table in which i have to adda JButton.
我在做什么
TableColumnModel colModel = table.getColumnModel();
colModel.getColumn(0).setCellEditor(new MYCellEditor(new JCheckbox()));
MyCellEditor extends DefaultCellEditor{
public MyCellEditor(JCheckbox checkbox){
super(checkbox);
Jbutton button = new JButton("Start");
//actionlistener for button.
}
}
MyRenderer extends DefaultTablecellRenderer{
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column) {
//return a button for column ==0
}
我的理解是Celleditor对列中的所有单元格都有相同的按钮实例。因此，如果我单击一个按钮，文本将从开始更改为停止，但如果我单击其他行中的按钮则无法正常工作..调试后显示文本已被删除。
My understanding is that the Celleditor has same instance of button for all cells in a column. So if i click on one button the text changes from "Start" to "stop" but if i click on button in other row it doesnt work.. After debugging it shows that the text is alreadt Stop .
我如何在每一行中有不同的按钮实例？
How can i have different instance of button in each row ?
