Java SWT：Table 滚动在对话框中不起作用

Question

我需要向对话框中添加一个 table，我正在用虚假内容填充它。显示对话框时，table没有滚动，所以最后的内容不可见。

可能与Dialog不可调整大小有关？我找不到使对话框可调整大小的方法。有可能吗？

这是我打开对话框的方式：

BetClubDialog dialog = new BetClubDialog(getShell(), SWT.DIALOG_TRIM | SWT.PRIMARY_MODAL, null);
String result = dialog.open();

这是我的对话框，带有 Table 和虚拟内容：

public class BetClubDialog extends Dialog {

    protected String result;
    protected Shell shell;
    private Club clubToEdit;

    /**
     * Create the dialog.
     * @param parent
     * @param style
     */
    public BetClubDialog(Shell parent, int style, Club clubToEdit) {
        super(parent, style);
        this.clubToEdit = clubToEdit;
        setText("Gestionar Peña de Apuesta");
    }

    /**
     * Open the dialog.
     * @return the result
     */
    public String open() {
        createContents();

        Rectangle parentSize = getParent().getBounds();
        Rectangle shellSize = shell.getBounds();
        int x = parentSize.x + (parentSize.width - shellSize.width) / 2;
        int y = (int) (parentSize.y + (parentSize.height - shellSize.height) / 3.5);
        shell.setLocation(new Point(x, y));
        shell.setLayout(new GridLayout(1, false));

        Composite topComposite = new Composite(shell, SWT.NONE);
        topComposite.setLayout(new GridLayout(2, false));
        topComposite.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, false, false, 1, 1));

        Label lblClubName = new Label(topComposite, SWT.NONE);
        lblClubName.setText("Peña:");

        Label lblClubNameValue = new Label(topComposite, SWT.NONE);
        lblClubNameValue.setText("Dummy");

        Composite clubComposite = new Composite(shell, SWT.NONE);
        clubComposite.setLayout(new GridLayout(1, false));
        clubComposite.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true, 1, 1));

        Table membersTable = new Table(clubComposite, SWT.BORDER | SWT.CHECK | SWT.FULL_SELECTION);
        membersTable.setHeaderVisible(true);
        GridData gd_membersTable = new GridData(SWT.FILL, SWT.FILL, true, true, 1, 1);
        gd_membersTable.minimumHeight = -1;
        membersTable.setLayoutData(gd_membersTable);

        TableColumn tblclmnName = new TableColumn(membersTable, SWT.NONE);
        tblclmnName.setWidth(150);
        tblclmnName.setText("Nombre");

        TableColumn tblclmnCommonPhoneNumber = new TableColumn(membersTable, SWT.NONE);
        tblclmnCommonPhoneNumber.setWidth(120);
        tblclmnCommonPhoneNumber.setText("Teléfono");

        TableColumn tblclmnCommonMoney = new TableColumn(membersTable, SWT.NONE);
        tblclmnCommonMoney.setWidth(150);
        tblclmnCommonMoney.setText("Participación Habitual");   

        // populate Table
        for (int i=0; i<50; i++) {
            TableItem tableItem = new TableItem(membersTable, SWT.NONE);                    
            tableItem.setText(new String[] {"person "+i, "610610620", "100"});
        }                       

        shell.open();
        shell.layout();
        Display display = getParent().getDisplay();
        while (!shell.isDisposed()) {
            if (!display.readAndDispatch()) {
                display.sleep();
            }
        }

        return result;
    }

    /**
     * Create contents of the dialog.
     */
    private void createContents() {
        shell = new Shell(getParent(), getStyle());
        shell.setSize(550, 550);
        shell.setText(getText());
    }
}

好的，我终于解决了这个问题，删除了这一行：

 gd_membersTable.minimumHeight = -1;
