创建新的JFrame然后关闭后，继续执行代码 [英] Continue code execution after new JFrame is created and then closed

问题描述

所以这可能是一个愚蠢的问题，但我无法弄清楚. 基本上我有MainWindow，当我按下按钮时，将出现一个名为PartSelectionWindow的新窗口，其中包含一个JTable(JTable用自定义表模型填充).然后，我选择一行，然后按OK返回到MainWindow并使用选定的信息.问题出在这里:

So this is probably a silly question but I just cant figure it out. Basically I have my MainWindow, when I press a button a new window should appear named PartSelectionWindow that contains a JTable (the JTable is filled out with a custom table model). Then I select a row and press ok to go back to the MainWindow and work with the info selected. Here's the problem:

如果我对PartSelectionWindow使用JFrame，则在关闭窗口之后，代码不会在MainWindow按钮事件中继续执行

If I use a JFrame for the PartSelectionWindow, after the window is closed the code execution does not continue in the MainWindow button event

如果我使用JDialog，则Jtable不会用自定义模型填充，并且它的按钮没有响应，只能通过单击JDialog的X来关闭它.好像它已被禁用.调试时，我注意到它确实在关闭JDialog之后尝试填写表.我在某处读到这可能是因为setVisible设置为true后代码暂停了，所以我尝试在setVisible设置为true之前将代码填充JTable，但仍然无法正常工作.

If i use a JDialog, the Jtable is not filled out with the custom model and the button for it does not respond, it can only be closed by clicking on the X of the JDialog. It's as if it was disabled. When debugging I noticed it DOES try to fill out the table AFTER closing the JDialog. I read somewhere that this may be because the code is paused after the setVisible is set to true, so I tried putting the code to fill out the JTable BEFORE the setVisible is set to true but it still does not work.

强制性代码:

    //MainWindow button event when tryng to use new JFrame
    private void btnSetupListActionPerformed(java.awt.event.ActionEvent evt) {                                             
        //call to new JFrame
        new partsWindow();
        //after closing partsWindow the next line of code does NOT execute
        txtPartNum.setText(PartsWindow.jpart.getPartNumber());
    }  

    //MainWindow button event when tryng to use new JDialog
    private void btnSetupListActionPerformed(java.awt.event.ActionEvent evt) {                                             
        //call to new JDialog
        new partsDialog(this, true);
        //after closing partsWindow the next line of code does NOT execute
        txtPartNum.setText(PartsWindow.jpart.getPartNumber());
    }  

JDialog窗口的构造函数

Constructor for JDialog window

public partsDialog(java.awt.Frame parent, boolean modal) {
    super(parent, modal);
    initComponents();
    this.setTitle("Setup Material Client");
    this.setVisible(true);
    this.setLocationRelativeTo(null);
    jTable1.getTableHeader().addMouseListener(new partsDialog.ColumnFitAdapter());
    jTable1.getTableHeader().setReorderingAllowed(false);
    GetBomForSetupMaterial = jtrace.GetBomForSetupMaterial(Main.station);
    jTable1.setModel(new PartModel(GetBomForSetupMaterial.getPartPositionList()));
}

任何帮助将不胜感激.

推荐答案

要说明我的评论，您可以使用以下代码(简化)

To ilustrate my comment you can use code like this (simplified)

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JLabel;


public class JDialogTest extends JDialog {
private static final long serialVersionUID = 1L;
private String text;
private JTextField textField;

public JDialogTest(JFrame owner, String text){
    super(owner,true);
    this.text = text;
    init();
}


private void init() {
    this.getContentPane().setLayout(new BorderLayout());
    JButton btnContinue = new JButton("Close me and continue");
    btnContinue.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            JDialogTest.this.dispose(); 
        }
    });
    textField = new JTextField();
    this.getContentPane().add(new JLabel(text),BorderLayout.NORTH);
    this.getContentPane().add(textField,BorderLayout.CENTER);
    this.getContentPane().add(btnContinue,BorderLayout.SOUTH);
    this.pack();
}

public JTextField getTextField() {
    return textField;
}

public static void main(String[] args) {
    JFrame frame = new JFrame();
    frame.setVisible(true);
    JDialogTest test = new JDialogTest(frame, "Hello");
    System.out.println("I open");
    test.setLocationRelativeTo(null);
    test.setVisible(true);
    System.out.println("Good you closed it value is " + test.getTextField().getText());
    frame.setVisible(false);

}

 }

我刚刚传递了一些文本以JLabel结尾，您应该传递表格或有关如何创建它的信息

I just passed some text to end up in JLabel you should pass your table or info on how to create it
