Динамически добавить один или несколько JPanels к JScrollPane - (Flow) проблемы компоновки

2015-05-28 5 views

У меня есть окно настроек с JScrollPane [smtpPanelList] в JTabbedPane [settingsTabs] - на вкладке 1. Тем не менее, я хочу добавить случайное число nr. настроек SMTP в smtpPanelList. Эти настройки сконструированы в отдельный JPanel [SmtpSettings].Динамически добавить один или несколько JPanels к JScrollPane - (Flow) проблемы компоновки

Я пробовал много разных решений, но ни один из них не работал. Проблема заключается в том, когда я добавляю их в JPanel [lista] - с FlowLayout - который находится внутри smtpPanelList, его добавленный, но отображаемый по горизонтали, а не под друг друга.

Просмотреть скриншот video.

Здесь следует коды:

settingsWindow.java

import java.util.prefs.Preferences; 

public class settingsWindow extends javax.swing.JFrame { 
public static final String SETTINGS = "DLP.settings"; 
public static final String SETTINGSEMAILCONTENT = "emailContent"; 
public ArrayList<SmtpSettings> smtp_list = null; 
public int ID = -1; 
public SmtpSettings smtp_tmp = null; 

private Preferences prefs = null; 

public settingsWindow() { 
    initComponents(); 
    prefs = Preferences.userRoot().node(SETTINGS); 
    emailContent.setText(prefs.get(SETTINGSEMAILCONTENT, emailContent.getText())); 

    smtpPanelList.setLayout(null); 

    smtp_list = new ArrayList<SmtpSettings>(); 
    smtpPanelList.setViewportView(lista); 
    lista.setLayout(new FlowLayout(FlowLayout.TRAILING));

Возможно, вместо этого используется 'GridBagLayout'? – MadProgrammer

Пробовал и получил тот же результат. :( – Zoli

Используйте что-то вроде GridBagLayout

Layout

private void addNewSmtpAccountActionPerformed(java.awt.event.ActionEvent evt) { 

    GridBagConstraints gbc = new GridBagConstraints(); 
    gbc.gridwidth = gbc.REMAINDER; 
    gbc.fill = gbc.HORIZONTAL; 
    gbc.weightx = 1; 

    ID++; 
    smtp_tmp = new SmtpSettings(this, ID); 
    //smtp_tmp.setBounds(0, (ID * smtp_tmp.getSize().height)+5, 600, 100); 
    lista.add(smtp_tmp, gbc); 
    lista.revalidate(); 

    smtp_list.add(smtp_tmp); 

}

Кроме того, избегайте использования setPreferred/Minimum/MaximumSize
