Question

如前所述，我Main Frame包含JXTaskPainContainer，jPanel1和jButton2以及AddButton，其中包含动态btn。布局为here。

主要课程：

public class Main extends javax.swing.JFrame{
public static JXTaskPaneContainer taskPaneContainer;
public static int count = 2;

public Main() {
   initComponents();

   taskPaneContainer = new JXTaskPaneContainer();
   jPanel1.setLayout(new GridLayout(1,1));
   jPanel1.add(taskPaneContainer, BorderLayout.EAST);
}

private void addMenu(String Title) {
   final JXTaskPane actionPane = new JXTaskPane();
   actionPane.setSpecial(true);
   JPanel opaquePanel = new JPanel();
   opaquePanel.setOpaque(true);
   JButton btn = new JButton("Test");
   btn.setActionCommand(Integer.toString(count));
   cardLayoutPanel.add(new Test(count), "Test"+Integer.toString(count));

   opaquePanel.add(btn);
   actionPane.add(opaquePanel);
   taskPaneContainer.add(actionPane);
}

 private void addButtonActionPerformed(java.awt.event.ActionEvent evt) {                                            
        count++;
        addMenu("Menu " + count);
 }

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
       Test.jButton1.doClick(); //call from Test panel
}
}

此处测试小组：

public class Test extends javax.swing.JPanel{

/**
* Creates new form Test
* @param val
*/

public Test(int val){
   initComponents();
   jButton1.setActionCommand(Integer.toString(val));
}

public Test(){        
   initComponents();
}

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt){
   System.out.println("test"+evt.getActionCommand());
}
}

现在当我点击jButton2上的Main frame时，我想从jButton1致电Test panel并获取他们的actionCommand。点击addButton后，它会添加动态btn = new JButton("Test")，并引用Test panel。我想要做的是添加动态btn，例如，如果我们添加btn2, btn3, btn4,然后使用jButton2，我想doClick()所有jButton1 actionCommands addMenu()

当我在Test.jButton1.setActionCommand(Integer.toString(count)); Test.jButton1.doClick();中添加这行代码时：

addButton

然后，每次点击jButton1，btn2, btn3, btn4 jButton1的所有jButton2都会被点击。但是，当我想使用Main frame中的private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) { Test.jButton1.setActionCommand(Integer.toString(count)); Test.jButton1.doClick(); }点击所有jButton1时：

btn4

但在这种情况下，只点击了上一个jButton1（即btn2, btn3, btn4）。我想问一下，如何使用jButton2一次点击动态添加的$ImageName = '/IMAGES/testImage.jpg'; //Download the Image File $base_url = 'https://image.jimcdn.com/app/cms/image/transf/none/path/sa6549607c78f5c11/image/ia62ed3191fcc424f/version/1457278719/athens-european-best-destinations.jpg'; $image_size = getimagesize($base_url); $image_width = $image_size[0]; $image_height = $image_size[1]; $src_image = imagecreatefromjpeg($base_url); //Copy Image Object To File imagejpeg($src_image, $ImageName, 100); <pre> {}？}？任何帮助都非常感谢。

使用getter而不是静态调用＆＃39; Test.jButton1＆＃39;

//include imports to make it an MCVE
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JPanel;
public class Test extends javax.swing.JPanel{

    JButton jButton1;   

    public Test(int val){
        initComponents();
        jButton1.setActionCommand(Integer.toString(val));
    }

    public Test(){        
        initComponents();
    }

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt){
        System.out.println("test"+evt.getActionCommand());
    }

    /**
     * Add a getter, so you can get jButton1 
     */
    public JButton getjButton1() {
        return jButton1;
    }
}

如果jPanel1是Test的一个实例，你可以通过以下方式获得jButton1：

    JButton jButton1 = jPanel1.getButton1();

或者点击

jPanel1.getButton1().doClick();

jButton立即点击
