![Array of Text Fields
You can create Array of Text fields by:
JTextField[][] txt = new JTextField[x][y];
for (int i = 0; i < x; i++) {
for (int j = 0; j < y; j++) {
txt[i][j] = new JTextField(10);
panel.add(txt[i][j]);
txt[i][j].setHorizontalAlignment(JTextField.CENTER);
if (i == j) {
txt[i][j].setText("1");
txt[i][j].setEditable(false);
} txt[i][j].addKeyListener(this);
}}](https://image.slidesharecdn.com/gettingstartedwithguiprogramming2-130201055004-phpapp01/85/Getting-started-with-GUI-programming-in-Java_2-9-320.jpg)
![Combo box
To Create Combo box :
JComboBox operations_txt= new JComboBox(new String[]{"<=", "=", ">="});
Operation_txt. getSelectedItem();](https://image.slidesharecdn.com/gettingstartedwithguiprogramming2-130201055004-phpapp01/85/Getting-started-with-GUI-programming-in-Java_2-10-320.jpg)
Getting started with GUI programming in Java_2
- 1. GETTING STARTED WITH GUI PROGRAMMING 2 By .Muhammad Shebl
- 2. OBJECTIVES 1. Labels & Images 2. Buttons 3. Text Fields & Text Area 4. Combo Boxes 5. Check box 6. Set bounds layout 7. Pack() & setResizable() 8. Menus
- 3. Labels : JLabel lab=new JLabel(“MUFIX”); ImageIcon icon = new ImageIcon("sigin.png"); JLabel lab=new JLabel(icon );
- 4. BUTTONS : Adding Event : JButton jbt = new JButton("OK"); jbt.addActionListener(this ); Add icon image : ImageIcon icon = new ImageIcon("sigin.png"); JButton jbt = new JButton(icon);
- 5. BUTTONS : Roll over icon : ImageIcon icon = new ImageIcon("sigin.png"); JButton jbt = new JButton(icon); Jbt.setRolloverIcon(icon);
- 6. BUTTONS: Roll Pressedicon : ImageIcon icon = new ImageIcon("sigin.png"); JButton jbt = new JButton(icon); jbt.setPressedIcon(icon);
- 7. TEXT AREA If you want to let the user enter multiple lines of text, you have to create several instances of JTextField. A better alternative is to use JTextArea, which enables the user to enter multiple lines of text. JTextArea jtaNote = new JTextArea(5, 20);
- 8. TEXT FIELDS KEY LISTNERS : // Create a text field with text "Type Name Here" JTextField jtfName = new JTextField("Type Name Here"); jtfName .addKeyListener(this);
- 9. Array of Text Fields You can create Array of Text fields by: JTextField[][] txt = new JTextField[x][y]; for (int i = 0; i < x; i++) { for (int j = 0; j < y; j++) { txt[i][j] = new JTextField(10); panel.add(txt[i][j]); txt[i][j].setHorizontalAlignment(JTextField.CENTER); if (i == j) { txt[i][j].setText("1"); txt[i][j].setEditable(false); } txt[i][j].addKeyListener(this); }}
- 10. Combo box To Create Combo box : JComboBox operations_txt= new JComboBox(new String[]{"<=", "=", ">="}); Operation_txt. getSelectedItem();
- 11. Check box : // Create a check box with text bold JCheckBox jchkBold = new JCheckBox("Bold"); jchkBold.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { if (jchkBold.isSelected()) { // your Action } } });
