所以我有两个类，一个叫ApplicationViewer，一个叫PetshopOverview。我希望applicationviewer使用JTabbedPane在两个选项卡中显示一些信息。我需要从扩展JScrollPane的另一个类获取一些信息，但是，该选项卡不显示信息。我看了各种答案，但似乎我的工作不正常。请参见下面的代码：如何添加组件到JTabbedPane
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);
}
这是其他类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);
宠物店：
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("", " ");
}
}
您可以添加“PetShop”类吗？ –
在这里你去@canlekili –
谢谢我刚创建petshop任意类。 –
