[英]Adding actionlistener of column in a jtable
Hi everyone.. I need some help again. 大家好..我还需要一些帮助。 :)
:)
How to do this? 这个怎么做? When I click the column t1, another form must pop-up explaining what happens to column t1, say, at time 1, Instruction 1 is in fetch stage.
当我单击列t1时,必须弹出另一个表单,说明列t1会发生什么,比如说,在时间1,指令1处于获取阶段。 Then, when I click naman t2 column, Instruction 2 is in fetch stage and Instruction 1 is in Decode stage., so on and so forth.
然后,当我点击naman t2列时,指令2处于提取阶段,指令1处于解码阶段。依此类推。
Thank you in advance. 先感谢您。 I really need your help.. Regards.. :)
我真的需要你的帮助..问候.. :)
You need to add following chunk of code, 你需要添加以下代码块,
table.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
// This is for double click event on anywhere on JTable
if (e.getClickCount() == 2) {
JTable target = (JTable) e.getSource();
int row = target.getSelectedRow();
int column = target.getSelectedColumn();
// you can play more here to get that cell value and all
new DialogYouWantToOpen(row, Column);
}
}
});
A Dialog which will be opened on double click. 双击打开的对话框。
class DialogYouWantToOpen extends JDialog{
JLabel testLabel = new JLable();
public DialogYouWantToOpen(int row, int column){
setSize(200,200)
setLayout(new FlowLayout());
testLabel.setText("User double clicked at row "+row+" and column "+ column);
add(testLabel);
}
}
Generaly it should go something like this 通常它应该是这样的
Listener listener = new Listener() {
public void handleEvent(Event e) {
TableColumn column = (TableColumn) e.widget;
System.out.println(column);
}
};
you get the column out of event and then do what you want with it. 你从事件中得到列,然后用它做你想做的事。
