So fügen Sie Komponente zu JTabbedPane

Question

Also habe ich zwei Klassen, eine namens ApplicationViewer und eine namens PetshopOverview. Ich möchte, dass der Applicationviewer einige Informationen in zwei Tabs mit JTabbedPane anzeigt. Ich muss einige Informationen von einer anderen Klasse erhalten, die JScrollPane erweitert, jedoch zeigt die Registerkarte die Informationen nicht an. Ich habe mir verschiedene Antworten angesehen, aber es scheint, dass meine nicht funktioniert. Siehe Code unten:

public class ApplicationViewer extends JFrame{ 


public void viewer(final ArrayList<PetShop> petshops){ 
    lookAndFeel(); //this calls the look and feel method which changes the looks of the frame. 

    PetshopOverview ov = new PetshopOverview(petshops); 



    Object[] columnNames = {"Name", "Address", "Phone Number", "Website", "Opening Time"}; //declaring columns names 
    Object[][] rowData = new Object[petshops.size()][columnNames.length]; //initializing rows. 
    DefaultTableModel listTableModel; 

    for (int i = 0; i < petshops.size(); i++) { //this for loop adds data from the arraylist to each coloumn. 
     rowData[i][0] = petshops.get(i).getName(); 
     rowData[i][1] = petshops.get(i).getAddress(); 
     rowData[i][2] = petshops.get(i).getPhoneNumber(); 
     rowData[i][3] = petshops.get(i).getWebsite(); 
     rowData[i][4] = petshops.get(i).getOpeningTime();  
    } 

    listTableModel = new DefaultTableModel(rowData, columnNames); 
    JPanel panelLB = new JPanel(); 
    JPanel panel = new JPanel(); 
    JPanel panelBT = new JPanel(); 
    JButton btnViewSum = new JButton("View Summary"); 
    JButton btnExp = new JButton("Export table data"); 

    //---------------------JTABLE AND JFRAME (adding adding table, panels and buttons to the jframe)-------------------------------------------------------- 

    JTable listTable; 
    listTable = new JTable(listTableModel); 




    listTable.setRowSelectionAllowed(true); 
    JScrollPane scroll = new JScrollPane(listTable); 
    scroll.setViewportView(listTable); 
    JFrame frame = new JFrame("PetShops"); 
    JTabbedPane tab = new JTabbedPane(); 

    tab.addTab("Tab1", scroll); 
    tab.addTab("Tab2", new PetshopOverview(petshops)); 
    JLabel lb = new JLabel("Welcome to Pet shop app"); 
    panelBT.add(lb); 
    panelBT.add(btnExp); 
    panelBT.add(btnViewSum); 
    frame.setLocationRelativeTo(null); 
    frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE); 
    frame.setSize(600, 400); 
    frame.add(panelBT); 
    frame.add(tab); 
    frame.getContentPane().add(panelBT, java.awt.BorderLayout.NORTH); 
    frame.getContentPane().add(tab, java.awt.BorderLayout.CENTER); 
    frame.setVisible(true); 
    } 

Das ist die andere Klasse PetshopOverview:

public class PetshopOverview extends JScrollPane{ 
    public PetshopOverview(ArrayList<PetShop> petshopsSum){ 


    Object[] columnNames = {"Name", "Opening Time"}; 
    Object[][] rowData = new Object[petshopsSum.size()][columnNames.length]; 
    DefaultTableModel listTableModel; 

    int size= petshopsSum.size(); 

    for (int i = 0; i < size; i++) { 
     rowData[i][0] = petshopsSum.get(i).getName(); 
     rowData[i][1] = petshopsSum.get(i).getOpeningTime(); 
    } 


    listTableModel = new DefaultTableModel(rowData, columnNames); 

//-------------------------JTABLE AND JFRAME-------------------------- 
JTable listTable; 
listTable = new JTable(listTableModel); 

Petshop:

public class PetShop { 
    private String name, address, phoneNumber, website, openingTime; 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

    public String getAddress() { 
     return address; 
    } 

    public void setAddress(String address) { 
     this.address = address; 
    } 

    public String getPhoneNumber() { 
     return phoneNumber; 
    } 

    public void setPhoneNumber(String phoneNumber) { 
     this.phoneNumber = phoneNumber; 
    } 

    public String getWebsite() { 
     return website; 
    } 

    public void setWebsite(String website) { 
     this.website = website; 
    } 

    public String getOpeningTime() { 
     return openingTime; 
    } 

    public void setOpeningTime(String openingTime) { 
     this.openingTime = openingTime; 
    } 


    public PetShop(String sName, String sAddress, String sPhoneNumber, String sWebsite, String sOpeningTime){ 
     this.name = sName; 
     this.address = sAddress; 
     this.phoneNumber = sPhoneNumber; 
     this.website = sWebsite; 
     this.openingTime = sOpeningTime; 
    } 




    @Override 
    public String toString(){ 
     return getName()+"\n" 
       +getAddress().replaceAll(":", "").replaceFirst("", " ")+"\n" 
       +getPhoneNumber()+"\n" 
       +getWebsite().replaceFirst("", " ")+"\n" 
       +getOpeningTime().replaceFirst(",", "").replaceFirst("", " ")+"\n\n"; 
    } 

    public PetShop(String sName, String sOpeningTime){ 
     this.name = sName; 
     this.openingTime = sOpeningTime; 
    } 

    public String toString2(){ 
     return getName()+": " 
       +getOpeningTime().replaceFirst(",", "").replaceFirst("", " "); 
    } 
} 

Answer 1

Sie sind fast da ich denke, man muss nur den Rahmen anpassen und fügen Ihre Komponenten dazu. Also in ApplicationViewer statt eine neue JFrame erstellen Sie Ihre Komponenten zu ApplicationViewer, die bereits eine JFrame ist. Und unter PetShopOverview müssen Sie die ViewportView der PetShopOverview auf listTable setzen.

Hier ist ein Beispiel:

PetShop

public class PetShop { 
String name; 
String openingTime; 
String address; 
String phoneNumber; 
String website; 

public PetShop(String name, String openingTime, String address, String phoneNumber, String website) { 
    this.name = name; 
    this.openingTime = openingTime; 
    this.address = address; 
    this.phoneNumber = phoneNumber; 
    this.website = website; 
} 

public String getName() { 
    return name; 
} 

public String getOpeningTime() { 
    return openingTime; 
} 

public String getAddress() { 
    return address; 
} 

public String getPhoneNumber() { 
    return phoneNumber; 
} 

public String getWebsite() { 
    return website; 
}} 

PetShopOverview:

public class PetShopOverview extends JScrollPane { 
public PetShopOverview(ArrayList<PetShop> petshopsSum) { 
    Object[] columnNames = { "Name", "Opening Time" }; 
    Object[][] rowData = new Object[petshopsSum.size()][columnNames.length]; 
    DefaultTableModel listTableModel; 

    int size = petshopsSum.size(); 

    for (int i = 0; i < size; i++) { 
     rowData[i][0] = petshopsSum.get(i).getName(); 
     rowData[i][1] = petshopsSum.get(i).getOpeningTime(); 
    } 

    listTableModel = new DefaultTableModel(rowData, columnNames); 

    // -------------------------JTABLE AND JFRAME-------------------------- 
    JTable listTable; 
    listTable = new JTable(listTableModel); 
    this.setViewportView(listTable); 
}} 

ApplicationViewer:

public class ApplicationViewer extends JFrame { 

public ApplicationViewer(ArrayList<PetShop> petshops) { 
    viewer(petshops); 
} 

public void viewer(final ArrayList<PetShop> petshops) { 

    PetShopOverview ov = new PetShopOverview(petshops); 

    Object[] columnNames = { "Name", "Address", "Phone Number", "Website", "Opening Time" }; // declaring columns 
                          // names 
    Object[][] rowData = new Object[petshops.size()][columnNames.length]; // initializing rows. 
    DefaultTableModel listTableModel; 

    for (int i = 0; i < petshops.size(); i++) { // this for loop adds data from the arraylist to each coloumn. 
     rowData[i][0] = petshops.get(i).getName(); 
     rowData[i][1] = petshops.get(i).getAddress(); 
     rowData[i][2] = petshops.get(i).getPhoneNumber(); 
     rowData[i][3] = petshops.get(i).getWebsite(); 
     rowData[i][4] = petshops.get(i).getOpeningTime(); 
    } 

    listTableModel = new DefaultTableModel(rowData, columnNames); 
    JPanel panelLB = new JPanel(); 
    JPanel panel = new JPanel(); 
    JPanel panelBT = new JPanel(); 
    JButton btnViewSum = new JButton("View Summary"); 
    JButton btnExp = new JButton("Export table data"); 

    // ---------------------JTABLE AND JFRAME (adding adding table, panels and buttons to the 
    // jframe)-------------------------------------------------------- 

    JTable listTable; 
    listTable = new JTable(listTableModel); 

    listTable.setRowSelectionAllowed(true); 
    JScrollPane scroll = new JScrollPane(listTable); 
    scroll.setViewportView(listTable); 
    JTabbedPane tab = new JTabbedPane(); 

    tab.addTab("Tab1", scroll); 
    tab.addTab("Tab2", new PetShopOverview(petshops)); 
    JLabel lb = new JLabel("Welcome to Pet shop app"); 
    panelBT.add(lb); 
    panelBT.add(btnExp); 
    panelBT.add(btnViewSum); 
    this.setLocationRelativeTo(null); 
    this.setDefaultCloseOperation(this.EXIT_ON_CLOSE); 
    this.setSize(600, 400); 
    this.add(panelBT); 
    this.add(tab); 
    this.getContentPane().add(panelBT, java.awt.BorderLayout.NORTH); 
    this.getContentPane().add(tab, java.awt.BorderLayout.CENTER); 
    this.setVisible(true); 
}} 

Hauptmethode:

public static void main(String[] args) { 
    ArrayList<PetShop> p = new ArrayList<PetShop>(); 
    p.add(new PetShop("a", "9", "street 1", "123", "www.a.com")); 
    p.add(new PetShop("b", "10", "street 2", "456", "www.b.com")); 
    p.add(new PetShop("c", "11", "street 3", "789", "www.c.com")); 
    p.add(new PetShop("d", "12", "street 4", "000", "www.d.com")); 

    ApplicationViewer v = new ApplicationViewer(p); 
    v.setVisible(true); 
} 

p.s. Ich habe gerade eine beliebige PetShop-Klasse erstellt
