swt GridLayout Multi-Column


Similar to the Single-Column Example above, if we instead use the GridLayout(int, boolean) constructor, we can create a layout with multiple columns.

In this case we create two columns, each of which are the same width.

public class MultiColumnGridLayoutExample {

    private final Display display;
    private final Shell shell;

    public MultiColumnGridLayoutExample() {
        display = new Display();
        shell = new Shell(display);

        // Create the layout and apply to the Shell
        shell.setLayout(new GridLayout(2, true));

        // Add the child controls to the Shell - in this case, in two columns
        final Button buttonA = new Button(shell, SWT.PUSH);
        buttonA.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
        buttonA.setText("Button A");
        final Button buttonB = new Button(shell, SWT.PUSH);
        buttonB.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
        buttonB.setText("Button B");
        final Button buttonC = new Button(shell, SWT.PUSH);
        buttonC.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
        buttonC.setText("Button C");
        final Button buttonD = new Button(shell, SWT.PUSH);
        buttonD.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
        buttonD.setText("Button D");

    public void run() {

        while (!shell.isDisposed()) {
            if (!display.readAndDispatch()) {

    public static void main(final String... args) {
        new MultiColumnGridLayoutExample().run();
