Salut am de facut un mini paint la facultate . Creati un editor grafic simplu, cu 3 butoane: de adaugare in fereastra a unui cerc, de adaugare a unui patrat si de stergere a unei forme (cerc sau patrat) -forma ce se poate selecta cu mouse-ul. /** * Created by on 4/6/2015. */ import javax.swing.*; import java.awt.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.MouseEvent; import java.awt.event.MouseListener; import java.awt.geom.Ellipse2D; import java.util.ArrayList; /** * Created by Angheluta on 4/6/2015. */ public class Main extends JFrame implements ActionListener,MouseListener{ JButton b1; JButton b2; JButton b3; int x,y,x1,y1; int x3,y3; String nume=" "; ArrayList<Dreptunghi> dreptunghis = new ArrayList<Dreptunghi>(); ArrayList<cerc> cercs =new ArrayList<cerc>(); public Main(){ b1 =new JButton("Dreptunghi"); b1.setBounds(10,20,100,20); b1.addActionListener(this); b2 =new JButton("Cerc"); b2.setBounds(120,20,100,20); b2.addActionListener(this); b3 =new JButton("Sterge"); b3.setBounds(220,20,100,20); b3.addActionListener(this); addMouseListener(this); add(b1); add(b2); add(b3); setLayout(null); setSize(600,600); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setVisible(true); } public void paint(Graphics g) { if(nume.equals("Dreptunghi")) { for (Dreptunghi d : dreptunghis) { d.paint(g); } } if(nume.equals("Cerc")) { for(cerc c : cercs) { c.paint(g); } } } @M2G
