SWING:

1.       Jlabel

void setIcon(Icon icon);

Icon getIcon();

void setText(String text);

String getText();

2.       jbutton

void setIcon(Icon icon);

icon getIcon();

void setText(String text);

String getText();

3.       JtextField

Klasa JtextFiled słuzy do definiowania klatek, używanych zazwyczaj do wprowadzania jednowierszowych tekstów

void setText(String text);String getText()

4.       JtextArea - Do definiowania edytorów

void setText(String text);void append(String text);void insert (String text, int pos);

void setEditable(boolean edit);

5.       JcomboBox - Lista opadająca.

void addItem(Object item);void insertItemAt(Object item, int index);

void removeItem(Object item);void removeItemAt(int index);void removeAllItems();

int getSelectedIndex()Object getSelectedItem();

6.       JcheckBox – do definiowania opcji odhaczanych

Int getStateChange() – dostarcza info o nowym stanie opcji: SELECTED, DESELECTED

7.       JradioButton – OPCJE RADIOWE

Int getStateChange()

Przykład:

import java.awt.*;import java.awt.event.*;import javax.swing.*;

public class Daltonista extends JFrame implements ActionListener

{

JPanel p;JButton r,g,b,z;

public static void main(String [] args)

   {

              Daltonista f= new Daltonista("Czy jestes daltonistą ?",320,200);

              f. setVisible(true);

   }

public Daltonista(String s, int w,int h)

   {

              super(s);

              setSize(w,h);

              getContentPane().setLayout(new BorderLayout());

              p = new JPanel();

              JPanel pb = new JPanel();

              pb.setLayout(new GridLayout(1,3));

              getContentPane().add(p, BorderLayout.CENTER);

              getContentPane().add(pb, BorderLayout.SOUTH);

              r=new JButton("red");              g=new JButton("green");              b=new JButton("blue");              z=new JButton("Close");

              if (source == r)
