Asemanari si deosebiri cu AWT

Tehnologia Swing extinde AWT.

import javax.swing.*;

import java.awt.*; //Font, Color, ...

import java.awt.event.*;

Conventia ”J”java.awt.Button - javax.swing.JButton

java.awt.Label - javax.swing.JLabel,etc.

Noi gestionari de pozitionare: BoxLayout

si SpringLayout

Folosirea HTML

JButton simplu = new JButton("Text simplu");

JButton html = new JButton("<html>Text formatat</html>");

Folosirea ferestrelor

Frame f = new Frame();

f.setLayout(new FlowLayout());

f.add(new Button("OK"));

JFrame jf = new JFrame();

jf.getContentPane().setLayout(new FlowLayout());

jf.getContentPane().add(new JButton("OK"));

jf.setDefaultCloseOperation(

Modele: BoundedRangeModel, ButtonModesi SingleSelectionModel

JSlider slider = new JSlider();

BoundedRangeModel model = slider.getModel();

model.addChangeListener(new ChangeListener() {

public void stateChanged(ChangeEvent e) {

// Sursa este de tip BoundedRangeModel

BoundedRangeModel m =

(BoundedRangeModel)e.getSource();

// Trebuie sa interogam sursa asupra schimbari

System.out.println(

"Schimbare model: " + m.getValue());

}

});

JList list = new JList(culori);

ListSelectionModel sModel = list.getSelectionModel()

sModel.addListSelectionListener(new ListSelectionListener() {

public void valueChanged(ListSelectionEvent e) {

// Schimbarea este continuta in eveniment

if (!e.getValueIsAdjusting()) {

System.out.println("Selectie curenta: " +

e.getFirstIndex());

}}

});

18

Initializarea

Object elemente[] = {"Unu", new Integer(2)};

JList lista = new JList(elemente);

DefaultListModel model = new DefaultListModel();

model.addElement("Unu");

model.addElement(new Integer(2));

JList lista = new JList(model);

ModelLista model = new ModelLista();

JList lista = new JList(model);

22




class Test implements ListSelectionListener {

...

public Test() {

...

// Stabilim modul de selectie

ListSelectionModel.SINGLE_SELECTION);// sau SINGLE_INTERVAL_SELECTION

// MULTIPLE_INTERVAL_SELECTION

// Adaugam un ascultator

ListSelectionModel model = list.getSelectionModel

model.addListSelectionListener(this);

...}


if (e.getValueIsAdjusting()) return;

int index = list.getSelectedIndex();

...

}}

23



Obiecte de tip Renderer

Un renderer este responsabil cu afisareaarticolelor unei componente.

class MyCellRenderer extends JLabel

implements ListCellRenderer {

public MyCellRenderer() {

setOpaque(true);

}

public Component getListCellRendererComponent(

JList list, Object value, int index,

boolean isSelected, boolean cellHasFocus) {

setText(value.toString());setBackground(isSelected ?

Color.red : Color.white);

setForeground(isSelected ?

Color.white : Color.black);

return this;

}

}...

list.setCellRenderer(new MyCellRenderer());

24



Clasa JComboBox

Clasa JSpinner

25



Tabele

Initializarea

String[] coloane = {"Nume", "Varsta", "Student"};

Object[][] elemente = {

{"Ionescu", new Integer(20), Boolean.TRUE},

{"Popescu", new Integer(80), Boolean.FALSE}};JTable tabel = new JTable(elemente, coloane);

26



Folosirea unui model

ModelTabel model = new ModelTabel();

JTable tabel = new JTable(model);

...

class ModelTabel extends AbstractTableModel {

String[] coloane = {"Nume", "Varsta", "Student"}

Object[][] elemente = {

{"Ionescu", new Integer(20), Boolean.TRUE},{"Popescu", new Integer(80), Boolean.FALSE}};

public int getColumnCount() {return coloane.lengt

public int getRowCount() {return elemente.length

public Object getValueAt(int row, int col) {

return elemente[row][col];

}public String getColumnName(int col) {

return coloane[col];

}

public boolean isCellEditable(int row, int col) {

// Doar numele este editabil

return (col == 0);

}}

27




1. Generate de editarea celulelor

public class Listener implements TableModelListener {

public void tableChanged(TableModelEvent e) {

// Aflam celula care a fost modificata

int row = e.getFirstRow();

int col = e.getColumn();TableModel model = (TableModel)e.getSource();

Object data = model.getValueAt(row, col);

...

}

}

...

tabel.getModel().addTableModelListener(new Listener

28



2. Generate de selectarea lini-ilor

class Listener implements ListSelectionListener {


if (e.getValueIsAdjusting()) return;

ListSelectionModel model =

(ListSelectionModel)e.getSource();

if (model.isSelectionEmpty()) {

// Nu este nici o linie selectata

...

} else {

int index = model.getMinSelectionIndex();

// Linia cu numarul index este prima selectata

...

}

}

}

...

tabel.setSelectionMode(

ListSelectionModel.SINGLE_SELECTION);

ListSelectionModel model = tabel.getSelectionMode

model.addListSelectionListener(new Listener());

return this;

}

}

Folosirea unui editorpublic class MyEditor

extends AbstractCellEditor

implements TableCellEditor {

public Object getCellEditorValue() {// Returneaza valoarea editata

...

}

...}

}

30

Arbori

String text = "<html>Radacina</html>";

DefaultMutableTreeNode root =

new DefaultMutableTreeNode(text);

DefaultMutableTreeNode numere =

new DefaultMutableTreeNode("Numere");

DefaultMutableTreeNode siruri =

new DefaultMutableTreeNode("Siruri");for(int i=0; i<3; i++) {

// Obtinem nodul selectat

DefaultMutableTreeNode node =

(DefaultMutableTreeNode)

tree.getLastSelectedPathComponent();

if (node == null) return;

// Obtinem informatia din nod

Object nodeInfo = node.getUserObject();

...

}

}

...// Stabilim modul de selectie

tree.getSelectionModel().setSelectionMode(

TreeSelectionModel.SINGLE_TREE_SELECTION);

// Adaugam un ascultator

tree.addTreeSelectionListener(new Listener());

32



Personalizarea nodurilor

TreeCellRenderer

• setRootVisible

•

setShowsRootHandles• putClientProperty

tree.putClientProperty("JTree.lineStyle", "Angled

// sau "Horizontal", "None"

• Specificarea unei iconite

ImageIcon leaf = createImageIcon("img/leaf.gif"

ImageIcon open = createImageIcon("img/open.gif"

ImageIcon closed = createImageIcon("img/closed.

DefaultTreeCellRenderer renderer =

new DefaultTreeCellRenderer();

renderer.setLeafIcon(leaf);

renderer.setOpenIcon(open);

renderer.setClosedIcon(closed);

tree.setCellRenderer(renderer);

33



Containere

1. Containere de nivel ınalt - JFrame,JDialog, JApplet

2. Containere intermediare

– JPanel

– JScrollPane

– JTabbedPane

– JSplitPane

– JLayeredPane– JDesktopPane

– JRootPane

34



JPanel

Permite gruparea componentelor.

JPanel p = new JPanel(new BorderLayout());

/* Preferabil, deoarece nu mai este construit si

un obiect de tip FlowLayout (implicit)*/

p.add(new JLabel("Hello"));

p.add(new JButton("OK"));

...

35

JScrollPane

Ofera suport pentru derulare

String elemente[] = new String[100];

for(int i=0; i<100; i++)

elemente[i] = "Elementul " + i;

JList lista = new JList(elemente);

JScrollPane sp = new JScrollPane(lista);

frame.getContentPane().add(sp);

36



JTabbedPane

Permite suprapunerea mai multorcontainere.

JTabbedPane tabbedPane = new JTabbedPane();

ImageIcon icon = new ImageIcon("smiley.gif");

JComponent panel1 = new JPanel();

panel1.setOpaque(true);

panel1.add(new JLabel("Hello"));

tabbedPane.addTab("Tab 1", icon, panel1,

"Aici avem o eticheta");

tabbedPane.setMnemonicAt(0, KeyEvent.VK_1);

JComponent panel2 = new JPanel();

...

37



JSplitPane

Ofera suport pentru separarea com-ponentelor.

JList list;

JPanel panel;

JTextArea text;

...

JSplitPane sp1 = new JSplitPane(

JSplitPane.HORIZONTAL_SPLIT, list, panel);

JSplitPane sp2 = new JSplitPane(

JSplitPane.VERTICAL_SPLIT, sp1, text);

frame.getContentPane().add(sp2);

38



Dialoguri - Clasa JDialog

• JOptionPane

JOptionPane.showMessageDialog(frame,

"Eroare de sistem !", "Eroare",

JOptionPane.ERROR_MESSAGE);

JOptionPane.showConfirmDialog(frame,

"Doriti inchiderea aplicatiei ? ", "Intreba

JOptionPane.YES_NO_OPTION,

JOptionPane.QUESTION_MESSAGE);

• JFileChooser

• JColorChooser

• ProgressMonitor

39



Desenarea

Metoda paint e responsabila cu:

• paintComponent

• paintBorder

• paintChildern

• ”double-buffering”

Afisarea imaginilor

ImageIcon img = new ImageIcon("smiley.gif");

JLabel label = new JLabel(img);

TransparentaPermite crearea de componente care nuau forma rectangulara.

40



Dimensiunile componentelorInsets insets = getInsets();

int currentWidth = getWidth() -

insets.left - insets.right;

int currentHeight = getHeight() -

insets.top - insets.bottom;

Contexte graficepublic void paintComponent(Graphics g) {

Graphics2D g2d = (Graphics2D)g;

// Desenam apoi cu g2d

// g este refolosit !!

// 1. Revenirea la starea initialag2d.translate(x, y); // modificam contexul
