我一直在环顾JTabbedPane的,并且似乎无法找到任何解决方案。JTabbedPane没有显示添加的其他选项卡
我使用的GridBagLayout作为经理,因为我更舒服的(我是新来的Java编程)。
我做了这个类,并与JPanel的扩展它,并添加另一个类的所有类,当我运行程序我看到的是黑屏,我将发布代码,所以你可以看到。
(测试类/ GUI类)
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import javax.swing.JComboBox;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
public class test1 extends JPanel {
JTextField ID, Name, Address1, Address2,
Post_Code, Landline, Mobile, Card_Name,
Card_Number, Expiry_Date, Security_Number,
Identification = new JTextField();
ResultSet rs1;
Connection conn;
PreparedStatement pst;
//JFrame frame = new JFrame("Test");
String items[] = {"Yes", "No"};
JComboBox box = new JComboBox(items);
public test1() {
JPanel jp2 = new JPanel(new GridBagLayout());
GridBagConstraints c1 = new GridBagConstraints();
c1.insets = new Insets(5, 5, 5, 5);
c1.gridx = 1;
c1.gridy = 0;
c1.anchor = GridBagConstraints.CENTER;
jp2.add(new JLabel("Customer Registration"), c1);
c1.gridx = 0;
c1.gridy = 1;
c1.anchor = GridBagConstraints.EAST;
jp2.add(new JLabel("ID"), c1);
c1.gridx = 1;
c1.gridy = 1;
c1.anchor = GridBagConstraints.WEST;
jp2.add(ID = new JTextField(10), c1);
c1.gridx = 0;
c1.gridy = 2;
c1.anchor = GridBagConstraints.EAST;
jp2.add(new JLabel("Name"), c1);
c1.gridx = 1;
c1.gridy = 2;
c1.anchor = GridBagConstraints.WEST;
jp2.add(Name = new JTextField(10), c1);
c1.gridx = 0;
c1.gridy = 3;
c1.anchor = GridBagConstraints.EAST;
jp2.add(new JLabel("Address"), c1);
c1.gridx = 1;
c1.gridy = 3;
c1.anchor = GridBagConstraints.WEST;
jp2.add(Address1 = new JTextField(15), c1);
c1.gridx = 1;
c1.gridy = 4;
c1.anchor = GridBagConstraints.WEST;
jp2.add(Address2 = new JTextField(15), c1);
c1.gridx = 0;
c1.gridy = 5;
c1.anchor = GridBagConstraints.EAST;
jp2.add(new JLabel("Post Code"), c1);
c1.gridx = 1;
c1.gridy = 5;
c1.anchor = GridBagConstraints.WEST;
jp2.add(Post_Code = new JTextField(10), c1);
c1.gridx = 0;
c1.gridy = 6;
c1.anchor = GridBagConstraints.EAST;
jp2.add(new JLabel("Landline"), c1);
c1.gridx = 1;
c1.gridy = 6;
c1.anchor = GridBagConstraints.WEST;
jp2.add(Landline = new JTextField(10), c1);
}
}
,结合所有JTabbedPane中的共同的类:
进口javax.swing.JFrame中; import javax.swing.JTabbedPane; import javax.swing.SwingUtilities;
公共类tabadd延伸的JFrame {
JTabbedPane tab = new JTabbedPane();
Customer_Registration CR = new Customer_Registration();
test1 g = new test1();
public tabadd() {
tab.add("Customer Registration", CR);
tab.add("Equipment Registration", g);
getContentPane().add(tab);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
tabadd m = new tabadd();
m.setTitle("Test");
m.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
m.setSize(1280, 720);
m.setLocationByPlatform(true);
m.setVisible(true);
}
});
}
}
会有多个类因此Customer_Registration类。
再次感谢你的帮助。
或更好帮助,发布[SSCCE](http://sscce.org/)。 – 2013-02-21 19:39:08
我测试了你的代码,我发现没有问题。而不是Customer_Registration,我发送null,我可以看到选项卡,所以也许你的问题在对象CR中。 – 2013-02-21 19:52:49
