Question

我有一个ExpandBar，上面有Group。

ExpandBar bar = new ExpandBar(this, SWT.V_SCROLL);
bar.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true, 1, 1));
ExpandItem item1 = new ExpandItem(bar, SWT.NONE, 0);
item1.setText(CORRANSWER);
item1.setControl(correctAnswerGroup);
item1.setImage(image);

正确答案小组的定义在此之前发生：

private void initCorrectAnswerGroup() {
    Group correctAnswerGroup = new Group(bar, SWT.BORDER);
    correctAnswerGroup.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true,
            true, 1, 1));
    correctAnswerGroup.setLayout(new GridLayout(1, false));

    (new Label(correctAnswerGroup, SWT.NONE)).setText(LABEL_TASK_TXT);

    taskTxt = new StyledText(correctAnswerGroup, SWT.READ_ONLY
            | SWT.V_SCROLL | SWT.H_SCROLL);
    gdTaskTxt = new GridData(SWT.NONE, SWT.NONE, false, false, 1, 1);
    gdTaskTxt.widthHint = 800;
    gdTaskTxt.heightHint = 200;
    taskTxt.setLayoutData(gdTaskTxt);

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

    Label answerTypeLabel = new Label(chooseAnswerTypeComposite, SWT.NONE);
    answerTypeLabel.setLayoutData(new GridData(SWT.LEFT, SWT.NONE, true,
            false, 1, 1));
    answerTypeLabel.setText(LABEL_ANSWER_TYPE);

    answerTypeCombo = new Combo(chooseAnswerTypeComposite, SWT.READ_ONLY);
    answerTypeCombo.setLayoutData(new GridData(SWT.LEFT, SWT.NONE, true,
            false, 1, 1));
    answerTypeCombo.setItems(new String[] { ANSWER_TYPE_STANDARD,
            ANSWER_TYPE_RULE });

    (new Label(correctAnswerGroup, SWT.NONE)).setText(LABEL_CORRECT_ANSWER);

    correctAnswerMsgTokenTextField = new TokenTextField(correctAnswerGroup,
            true, false, true, SWT.BORDER | SWT.V_SCROLL | SWT.H_SCROLL);
    GridData gdETxtCorrAnsMsg = new GridData(SWT.FILL, SWT.FILL, true,
            false, 1, 1);
    gdETxtCorrAnsMsg.heightHint = 40;
    correctAnswerMsgTokenTextField.getText()
            .setLayoutData(gdETxtCorrAnsMsg);
}

然而，ExpandBar的大小不正确。它水平和垂直切割小部件，根本不显示任何ScrollBars。它尝试使用ExpandItem的setHeight方法，但我试过的似乎既不工作...... 如何使ExpandBar拉伸垂直于correctAnswerGroup的整个大小并水平显示ScrollBars？

正确设置ExpandBar大小
