Usage

From source file:ControlSizeLocation.java

public static void main(String[] args) {
    Display display = new Display();
    Shell shell = new Shell(display);
    shell.setLayout(new FillLayout());
    Button button = new Button(shell, SWT.PUSH);

    shell.setSize(260, 120);/*w  w  w .j av  a2 s  .c o m*/
    shell.open();

    System.out.println("------------------------------");
    System.out.println("getBounds: " + button.getBounds());
    System.out.println("getLocation: " + button.getLocation());
    System.out.println("getSize: " + button.getSize());

    while (!shell.isDisposed()) {
