    Default SWT login form

    Hi,

    I want code to create a login form in SWT.


    The login form should contain user id, password fiels to enter the data, and a login button .

    My requirement is that when the user clicks the "enter" key from the keyboard, "login" button action should be done.

    Thanks in advance

    Default

    package testing;

    import org.eclipse.swt.SWT;
    import org.eclipse.swt.layout.*;
    import org.eclipse.swt.widgets.*;
    import org.eclipse.swt.events.*;

    public class check {
    Display display = new Display();
    Shell shell = new Shell(display);
    Label label1,label2;
    Text username;
    Text password;
    Text text;

    public check() {
    shell.setLayout(new GridLayout(2, false));
    shell.setText("Login form");
    label1=new Label(shell, SWT.NULL);
    label1.setText("User Name: ");

    username = new Text(shell, SWT.SINGLE | SWT.BORDER);
    username.setText("");
    username.setTextLimit(30);

    label2=new Label(shell, SWT.NULL);
    label2.setText("Password: ");

    password = new Text(shell, SWT.SINGLE | SWT.BORDER);
    System.out.println(password.getEchoChar());
    password.setEchoChar('*');
    password.setTextLimit(30);

    Button button=new Button(shell,SWT.PUSH);
    button.setText("Submit");
    button.addListener(SWT.Selection, new Listener() {
    public void handleEvent(Event event) {
    String selected=username.getText();
    String selected1=password.getText();

    if(selected==""){
    MessageBox messageBox = new MessageBox(shell, SWT.OK |
    SWT.ICON_WARNING |SWT.CANCEL);
    messageBox.setMessage("Enter the User Name");
    messageBox.open();
    }
    if(selected1==""){
    MessageBox messageBox = new MessageBox(shell, SWT.OK |
    SWT.ICON_WARNING |SWT.CANCEL);
    messageBox.setMessage("Enter the Password");
    messageBox.open();
    }
    else{
    MessageBox messageBox=new MessageBox(shell,SWT.OK|SWT.CANCEL);
    messageBox.setText("Login Form");
    messageBox.setMessage("Welcome:" + username.getText());
    messageBox.open();
    }
    }
    });
    username.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));
    password.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));

    shell.pack();
    shell.open();

    while (!shell.isDisposed()) {
    if (!display.readAndDispatch()) {
    display.sleep();
    }
    }
    display.dispose();
    }
    public static void main(String[] args) {
    new check();
    }
    }

    My requirement is if the user press "enter" key instead of "submit" button after entering the data in text message box should open

    Post You only need one line of code for...

    For having the "login" button as the default button you need just this line:
    Java Code:
    shell.setDefaultButton(loginButton);
    Greetings
