LWUIT: ButtonGroup

2010-07-16T09:15:00.001-07:00

The ButtonGroup component manages the selected and unselected states for a set of
RadioButtons. For the group, the ButtonGroup instance guarantees that only one
button can be selected at a time.


import javax.microedition.midlet.*;
import com.sun.lwuit.*;
import com.sun.lwuit.events.*;
import com.sun.lwuit.layouts.BorderLayout;

public class LwuitButtonGroup extends MIDlet implements ActionListener {
    public void startApp() {
        Display.init(this);
        Form f = new Form("Hello, MIDlet in LWUIT!");
        Command exitCommand = new Command("Exit");
        f.addCommand(exitCommand);
        f.setCommandListener(this);

        f.setTitle("ButtonGroup");

        RadioButton radioButton1 = new RadioButton("Radio Button 1");
        RadioButton radioButton2 = new RadioButton("Radio Button 2");
        RadioButton radioButton3 = new RadioButton("Radio Button 3");
        ButtonGroup buttonGroup1 = new ButtonGroup();
        buttonGroup1.add(radioButton1);
        buttonGroup1.add(radioButton2);
        buttonGroup1.add(radioButton3);

        RadioButton radioButtonB = new RadioButton("Radio Button B");
        ButtonGroup buttonGroup2 = new ButtonGroup();
        buttonGroup2.add(radioButtonA);
        buttonGroup2.add(radioButtonB);
        f.addComponent(radioButtonA);
        f.addComponent(radioButtonB);

        f.show();

    }

    public void pauseApp() {}
    public void destroyApp(boolean unconditional) {}
    public void actionPerformed(ActionEvent ae) {
        notifyDestroyed();
    }
}

LWUIT: GridLayout

2010-07-12T03:16:00.000-07:00

A GridLayout object places components in a grid of cells. Each component takes all
the available space within its cell, and each cell is exactly the same size.


 GridLayout gridLayout = new GridLayout(3, 2);
        f.setLayout(gridLayout);
        f.setTitle("GridLayout");
        
        f.addComponent(new Button("Button 1"));
        f.addComponent(new Button("Button 2"));
        f.addComponent(new Button("Button 3"));
        f.addComponent(new Label("Label 1"));
        f.addComponent(new Button("Button 4"));

LWUIT: FlowLayout

2010-07-12T00:53:00.000-07:00

The FlowLayout class provides a very simple layout manager that is the default
layout manager for Container objects.
The FlowLayout class puts components in a row, sized at their preferred size. If the
horizontal space in the container is too small to put all the components in one row,
the FlowLayout class uses multiple rows. To align the row to the left, right, or center,
use a FlowLayout constructor that takes an alignment argument.


        FlowLayout flowLayout = new FlowLayout();
        f.setLayout(flowLayout);
        f.setTitle("FlowLayout");
        
        f.addComponent(new Button("Button 1"));
        f.addComponent(new Button("Button 2"));
        f.addComponent(new Button("Button 3"));
        f.addComponent(new Label("Label 1"));
        f.addComponent(new Button("Button 4"));

LWUIT: BoxLayout

2010-07-12T00:41:00.000-07:00

The BoxLayout class puts components either on top of each other or in a row.


        BoxLayout boxLayout = new BoxLayout(BoxLayout.X_AXIS);
        f.setLayout(boxLayout);
        f.setTitle("BoxLayout: BoxLayout.X_AXIS");
        
        Button button1 = new Button("Button 1");
        Button button2 = new Button("Button 2");
        Button button3 = new Button("Button 3");
        f.addComponent(button1);
        f.addComponent(button2);
        f.addComponent(button3);


        BoxLayout boxLayout = new BoxLayout(BoxLayout.Y_AXIS);
        f.setLayout(boxLayout);
        f.setTitle("BoxLayout: BoxLayout.Y_AXIS");
        
        Button button1 = new Button("Button 1");
        Button button2 = new Button("Button 2");
        Button button3 = new Button("Button 3");
        f.addComponent(button1);
        f.addComponent(button2);
        f.addComponent(button3);

        f.addCommand(exitCommand);
        f.setCommandListener(this);

        BorderLayout borderLayout = new BorderLayout();
        f.setLayout(borderLayout);
        f.setTitle("BorderLayout");
        
        Label labelCenter = new Label("Center");
        Label labelEast = new Label("East");
        Label labelSouth = new Label("South");
        Label labelWest = new Label("West");
        Label labelNorth = new Label("North");
        f.addComponent(BorderLayout.CENTER, labelCenter);
        f.addComponent(BorderLayout.EAST, labelEast);
        f.addComponent(BorderLayout.SOUTH, labelSouth);

        notifyDestroyed();
    }
}

LWUIT: Layout

2010-07-07T09:49:00.000-07:00

The form takes care of positioning the components. It uses a layout manager to decide where everything goes. For you AWT and Swing jocks, this should sound familar. Layout managers are great for mobile applications because they are good at adjusting to different screen sizes and filling the available space gracefully.

LWUIT includes five layout managers.

FlowLayout places components from left to right in rows, just like English text.
BorderLayout has a large center area and four smaller areas around the edges.
BoxLayout arranges components in a single row or column.
GridLayout places components in a grid.
More complex layouts can be accomplished using GroupLayout and its helper class Group.

LWUIT

2010-06-17T09:53:00.000-07:00

LWUIT is a UI library that is bundled together with applications and helps content developers in creating compelling and consistent Java ME applications. LWUIT supports visual components and other UI goodies such as theming, transitions, animation and more.

Writing appealing cross device applications today in Java ME is challenging. Due to implementation differences in fonts, layout, menus, etc. the same application may look and behave very differently on different devices. In addition much of the advanced UI functionality is not accessible in LCDUI and requires the developer to write very low level "paint" type code. The Lightweight UI Toolkit was developed to address these issues. The Lightweight UI Toolkit makes it very easy to create compelling UI's that will look and behave the same on all devices using a programming paradigm similar to Swing. This Toolkit is able to run on CLDC1.1 MIDP2.0/CDC PBP/SE.

NetBeans IDE 6.9 Now Available for Download!

2010-06-16T17:31:00.000-07:00

The NetBeans team announced the availability of NetBeans IDE 6.9!

Download NetBeans IDE 6.9

NetBeans IDE 6.9 introduces the JavaFX Composer, a visual layout tool for building JavaFX GUI applications, similar to the Swing GUI builder for Java SE applications. With the JavaFX Composer, developers can quickly build, visually edit, and debug Rich Internet Applications (RIA) and bind components to various data sources, including Web services.

The NetBeans 6.9 release also features OSGi interoperability for NetBeans Platform applications and support for developing OSGi bundles with Maven. With support for OSGi and Swing standards, the NetBeans Platform now supports the standard UI toolkit and the standard module system, providing a unique combination of standards for modular, rich-client development.
