获取动态添加的jbutton动作命令 [英] Get dynamically added jbutton action command

问题描述

我有JFrame Main，它包含左侧JXTaskPainContainer（内容菜单）和右侧cardLayout面板。内容菜单有一个JButton btn（数据），当我们点击btn它显示在cardLayout面板上时 - > JPanel测试。在内容菜单下有addButton，它添加动态btn - > data2，data3，....这里给出的主框架布局：

I have JFrame Main which contains in left side JXTaskPainContainer (content menu) and right side cardLayout panel. Content menu has a JButton btn("data"), when we click btn it shows on cardLayout panel -> JPanel Test. Under content menu there is addButton, which adds dynamic btn -> "data2", "data3",.... The layout of Main frame given here:

Main frame

    | jButton2 |
    -------------
    |Content menu|         CardLayout Panel
    |----------  |------------------------------------|
    |    //shows |                                    |
    |data1 ------|-> Test jPanel [Test.add(jButton1)] |
    |data2 ------|-> Test jPanel [same as above     ] |
    |data3 ------|-> Test jPanel [same as above     ] |
    |  ...       |                                    |
    |----------  |------------------------------------|
    |  AddButton |                                    |
     //data2, data3 dynamically added by AddButton

我尝试过：



jButton2必须调用Test.jButton1：

What I have tried:

jButton2 must call Test.jButton1:

private void jButton2actionPerformed(java.awt.event.ActionEvent evt) {
        Test.jButton1.doClick(); //here I want to call all jButton1 (i.e. data2, data3,...)
}

但是当我点击jButton2时，它只调用最后点击的Test.jButton1。例如，如果我添加了动态data2和data3，那么只点击了data3的jButton1，因为data2没有任何意义。

我想问一下如何调用所有的Test.jButton1动作命令在Main类中动态添加data2，data3，...？

but when I click jButton2 it calls only last clicked Test.jButton1. For example, if I added dynamic data2 and data3, then only jButton1 of data3 is clicked, for data2 is no sense.
I would like to ask how can I call all the Test.jButton1 action commands of dynamically added data2, data3,... in Main class?

推荐答案

JButton button1 = new JButton（" new button"）;

button1 .setActinCommand（idActin）;

button1 .setActionListener（this）;



...

void actionPerformed（ActionEvent e）{

String idActin = e.getActionCommand（） ;

}



试试这个

JButton button1 = new JButton("new button");
button1 .setActinCommand(idActin );
button1 .setActionListener(this);

...
void actionPerformed(ActionEvent e) {
String idActin = e.getActionCommand();
}

Try this
