AWT

AWT Java.awt Package contains many classes and methods that allow you to create and manage GUI-Based application. Unlike any simple non-GUI application, GUI application do not terminate when main() method finishes the execution of its last statement. The basic functionalities provided by AWT are Component management. Event handling.

Layout Management.

Graphics Rendering.

Hierarchy of classes in java.awt Package

Components: -These include Labels, Text Fields, Menus, Buttons and other typical elements of user interface (UI). Containers: -Containers are generic AWT Components that can contain other components and containers. Panel: -A panel is a window that does not contain a title bar, menu bar or border. Panel is a super class for Applets. When we run an applet using are applet viewer, the applet viewer, the applet viewer provides the title and border. Frame: -frame encapsulates what is commonly thought of as a Window. It is a sub class of windows and has title bar, menu bar borders and resizing corners. The component class is an abstract class which includes large number of methods for positioning and sizing components, repainting, setting fonts and colors, changing window bounds, handling events etc.Example: -

Others Component classes1. Label: - Labels are text strings that can be used to label other UI components. Labels are passive conbols i.e. they do not generate any event.

Syntax: -

Label lb1=new Label(Enter Name);

Label lb2=new Label(Hello,Label.RIGHT);

2. Button: - The Button class creates a push button that generates an event when it is pressed. It can only have a textual label. The button class defines the following two constructors to create button objects.

Button()

Button(String s)

The first Constructor creates button with no label and other one creates button than has S as a label.

E.g.: -

Button bt = new Button(OK);

The Button class also defines methods to set and get the labels.

Void setLabel(String s);

String getLabel();

3. TextField: -A Text Field is a subclass of the Text component class. It can hold a single row of text and its width is either set to accommodate a string used in the constructor or set by an int parameter specifying the number of columns.

To create a text field, any of the following constructors can be used:

( TextField() ( Creates an empty textfield.

(TextField(int column) (A textfield with given width in columns.

( TextField(String s) (A textfield initialized with the given string.

( TextField(String s, int column) (A textfield with the given width in columns and initialized with the given string.

e.g.: - TextField tf=new TextField(Hello,20);

The above example creates a textfield with 20-columnwidth and initialized to Hello.

The TextField class and its superclass TextComponent provide several mthods to set and obtain text, to make a field editable or read only to make textfield that works like password field etc. Some of these methods are: -

( void setText(String s)

( String getText()

( Boolean is Editable()

( void setEditable(Boolean b)

( void Select(int start, int end)

( String getSelected Text()

The last two methods select a portion of text from text field. The first one selects the characters beginning a start position and ending at end.

And the last on returns the entire selected text.

4. TextArea: - TextArea also is a subclass of TextComponent class. It is a multiline input area that include scroll bars so that large amount of text can be entered and displayed.

Given below are the constructor that are available to create TextArea objects.

( TextArea()

( TextArea(String s)

( TextArea(int rows, int columns)

( TextArea(String s, int row, int columns)

( TextArea(String s, int rows, int column, int column, int scrollbars)

The TextArea class also Supports various methods defined in the TextComponent class, such as getText(), setText(), setEditable(), etc.

5. CheckBox: -Checkboxes are user interface components that have two states checked and unchecked (truth or false). Checkboxes can be of two types: -

( Non Exclusive Checkboxes: -These checkboxes enable you to select any number of checkboxes within a given series.

( Exclusive Checkboxes: -Only one Checkbox can be selected from within a group. These types of checkboxes are also known as radio buttons. They have a circulars appearance.

The Checkbox class has the following constructors: -

( Checkbox()

( Checkbox(String s)

( Checkbox(String s, Boolean state)

( Checkbox(String s, Boolean state, checkbox group)

The first constructor creates an empty and unselected Checkbox,

The second one creates a checkbox with a given string as label,

The third one allows to specify state also and

The last one creates a Check box which specifies the group name (radio button).E.g.: -

Checkbox cb1=new Checkbox (BCA);

Checkbox cb2= new Checkbox(MCA,true);

To create a series of radio buttons, first create an instance of checkbox Group, then create the checkboxes. Each Checkbox requires three parameters to be specified label, group name and whether it is initially selected (true) or not (false).

E.g: -

Checkbox Group cbg= new Checkbox Group();

Checkbox cb1=new Checkbox(red,true,cbg);

Checkbox cb2= new Checkbox(blue,false,cbg);

Checkbox cb3= new Checkbox(green,false,cbg);

Function Supported by Checkbox: -

( String getLabel()

( void setState(Boolean b)

( void setLabel(String s)

( CheckboxGroup getCheckboxGroup()

( Boolean getState()

( void setCheckboxGroup(CheckboxGroup g)

( Checkbox getSelectedCheckbox()

( void setSelectedCheckbox(Checkbox c)

6. Choice: -A choice list appears like a menu and enables selection of an item from that menu. The advantage of the choice list over radio buttons is that it occupies less space on the window. To create a choice list create an instance of the class. Choice by using the single default constructor provided and add the items using add() method.

Void add(String item)

e.g.: -

Choice ch=new Choice();

To add items into the list

ch.add(Cricket);

ch.add(Football);

ch.add(Hockey);

Various methods of Choice: -

( String getItem(int index)

( int getItemCount()

( int getSelectedIndex()

( String getSelectedItem()

( void select(String str)

( void select(int Position)

7. List: -The list class implements a scrollbar list of text items. A list objects shows any number of items in the visible window. A scrollbar automatically appears when it is required to scroll the list. A list object allows either a single selection or multiple selections.

The constructors of the list class are as follows: -

(List()

(List(int rows)

(List(int rows, Boolean multiple)

These constructors creates a list object with row specifying the number of visible items. The true Boolean value allows multiple selection modes.

To add items in the list object, the following two methods can be used:

(void add(String item)

(void add(String item, int index)

The second method adds the item at the specified index. The index value zero refers to the beginning and a value denotes the end of the list.

The first method adds the item to the end of the list.List also defines various methods to find out number of visible rows, total item in the list and also to return the item at a particular position.

(Int getRows()

(int getItemCount()

(void Select(String item)

(void select(int index)

(void getItem(int index)

For Single selection list we use:

(String getSelectedItem()

(int getSelctedIndex()

For multiple selection List:

(String[] getSelectedItems()

(int[] getSelectedIndexes()

8. Scroll bar(): -Scrollbar are used to selct5ed continuous values between a specified minimum and maximum. Scrollbars may be oriented horizontally or vertically.

The constructors are as follows: -

(Scrollbar()

(Scrollbar(int style)

(Scrollbar(int style, int initial, int thumbsize, int min, int max)

Here, Style specifies orientation of the scrollbar which is defined as constants VERTICAL and HORIZONTAL in the class. The number of units represented by the height of the thumb is passed in thumbsize.

E.g.: -

Scrollbar sb =new scrollbar(Scrollbar, HORIZONTAL, 0,10,-50,100)

Methods used in scrollbar are: -

(int getvalue()

(void setvalue(int newval)

(void setMinimum(int min)

(int getMinmum()

(void setMaximum(int max)

(int getMaximum()

9. Menus: -Menus are one of the primary user interface constructs in almost any windowed application. Each user created top-level window can have its own menu bar at the top of the screen. A menu bar can have a number of drop-down menus which in turn can have menu items submenus.

Steps to create a Menu bar: -

( Create an instance of the MenuBar class.

MenuBar mb=new MenuBar();

( Attach it to the frame using the setMenuBar() method.

setMenuBar(mb);

( To create a popup, Create an instance of the Menu class.

Menu m= new Menu(background);

( Add the popup to the menubar using the add() method.

mb.add(m);

( Create and add menu items to the popup using add() and MenuItem() methods.

m.add(new MenuItem(default));

( To have separator, use addSeparator() method.

( To disable any menu item use the set Enabled (false) method.

10. Dialog: -The Dialog class is a sub class of the window class, which defines a movable top-level window with a title bar. Dialogs are separate popup window that accepts input from the user. Unlike frames they have several restrictions such as

( They cannot have menu.

( They cannot be resized.

( They must be opened by a parent window in order to exit.

EVENT HANDLING

: -`Event is object that describes a state change in a source. It can be generated by user interaction with GUI controls.

E.g.: -

Pressing a button, entering character via Keyboard, Selecting an item in the List, Clicking / Selecting a checkbox.

Handling Events

:- Event handling involves that are automatically called when a user action causes an event to take place. An event is generated in response to just about anything that a user can do during the cycle of java program. Every movement of the mouse, keyboard and button click generates an event.

Event: - It is an object that describes a state change in a source. It can be generated by user interaction with GUI control.

E.G.: - Pressing a button, entering character via keyboard.

Event Source: - It is an object that generates an event sources may generate more than one type of event.

Examples:

Public void addtypeListener(Type Listener I)

Where Type Listener is any valid Listener

e.g.: - addkeyListener();

addMouseMotionListener()

Event Classes: - Event classes are used to encapsulate the information that identifies the exact nature of the event.

1. Action Event: - The Action event class defines an integer constant, Action Performed which can be used to identify an action event. It has the following constructor.

It has the following constructor

action Event (Object source, int type, string cmdstr)

Here, Argument source is the object reference where this event is generated type is the type of event and cmdstr is the command string associated with the event source.

2. Item Event: - It event refers to a change of state that is defined by a integer constant Item state changed.

It provides the following methods:

Object getItem()

int getStateChanged()

Item Select table getItemSelectable()

Item Event is generated by checkbox, List box, choice box .

3. Mouse Event: -This Event is generated when the user moves the mouse or presses a mouse button. It defines following Methods:

int getx()

int gety()

Point getPoint()

Point getClickCount()

4. Key Event: -This event is generated by the key board inputs i.e. when a key is pressed or released.

It provide following method: -

char getkeyChar()

int getKeyCode()

5. Window Event: -This event is generated when some operation is performed on a window.

Event Listener Interfaces1. Action Listener: -

This Interface defines a method

public void actionPerformed (ActionEvent e)

When is executed when an ActionEvent is generated from a source.

2. Item Listener: -The following method of this listener is executed when the state of an item changes:

public void itemStateChanged (ItemEvent e)

3. Adjustment Listener: -The adjustmentValueChanged() method of this listener is executed when an adjustment event occurs. Its signature is as follows:

public void adjustmentValueChanged (AdjustmentEvent e)

4. Key Listener: -The methods of this interface are involved when a key is pressed or when a character has been entered. It defines the following methods:

void keyPressed (KeyEvent e)

void keyReleased (KeyEvent e)

void keyTyped (KeyEvent e)

5. Mouse Listener: -This interface defines the following five methods:

void mouseClicked (MouseEvent e)

void mouseEntered (MouseEvent e)

void mouseExited (MouseEvent e)

void mousePressed (MouseEvent e)

void mouseReleased (MouseEvent e)

6. Mouse Motion Listener: -This interface defines two methods which are executed multiple times as the mouse is moved or dragged.

void mouseDragged (MouseEvent e)

void mouseMoved (MouseEvent e)

7. Window Listener: -It defines the following methods:

void windowActivated (WindowEvent e)

void windowClosed (WindowEvent e)

void windowClosing (WindowEvent e)

void windowDeactivated (WindowEvent e)

void windowDeiconified (WindowEvent e)

void windowIconified (WindowEvent e)

void windowOpened (WindowEvent e)SWING: -The AWT is not a very satisfactory tool for creating commercial applications because it was designed to use each platforms native components. Also the component set provided by AWT is limited and not suitable for advanced applications that use trees, tables, progress bars and other complex components.

The Java Foundation classes (JFC) are collections of classes used to develop graphical user interfaces. The JFC includes swing classes.

The JFC was developed by the combined efforts of Java soft, Netscape and IBM.

JFC Also includes:- The Accessibility API (Support I/O devices to aid those with disabilities.

The java 2D classes ( Support better fonts & graphic capabilities.

Drag & Drop support ( Ability to drag and drop objects to and from a java application and a native file system application.

SWING AND AWT: -Swing is an extension (not a replacement) of the AWT. It uses the same event model and the same layout managers. Both share the common super classes component and container.

Heavy Weight vs Light Weight Components : -AWT components use native peer components to display themselves on any platform. These components are called heavy weight because they require across platforms. Swing components are entirely java components. They are called light weight because they are not directly backed by a native peer object.

Pluggable Look and Feel (PLAF)

: -Pluggable look-and- feel feature allows multiple appearances and behaviors for a single component class without having to sub class the component for every look and feel. Look part of look-and feel works for appearance while feel part comes from how components interact with the user i.e. how they respond to event.Swing Packages: -The main package used to develop swing applications is javax.swing but the java.awt is also include in import statements because swing relives heavily on the common frame work shared with the AWT components.

Hierarchy of Heavy Weight classes

JFrame: -The JFrame class implements a top-level container which is maintained by the native platform it is a direct sub class of the Frame class and is used to create a swing application. A frame can automatically close when the close button of title bar is pressed, but to make this action cause the application to exit, window listener should be used.

JApplet: -JApplet is the JFC equivalent of the AWT Applet class. It defines a heavy weight container and is used to support swing components in an applet.

JDailog: - A Dialog window is used to get input from the user on to simply inform the user of an error. It is always associated with a frame, but floats independently of it.AWT PROGRAMMINGFONT EXAMPLEimport java.awt.*;
