java - Java SWT - グループ内の ScrolledComposite

Question

の中に入れるのに問題があります-ScrolledCompositeの中にGroup表示されませんGroup。ScrolledCompositeをスクロールする必要がありLabelます。

final private static Group group_netpbmOutput = new Group(shell, SWT.NONE);
final private static ScrolledComposite scroll_netpbmOutput = new ScrolledComposite(group_netpbmOutput, SWT.V_SCROLL | SWT.H_SCROLL);
final private static Label labelImage_netpbmOutput = new Label(scroll_netpbmOutput, SWT.BORDER);

//init Group
group_netpbmOutput.setLayout(new FillLayout());
formData = new FormData(((FormData)group_options.getLayoutData()).width, 200);
formData.top = new FormAttachment(group_options, 50, SWT.BOTTOM);
formData.left = new FormAttachment(group_options, 0, SWT.LEFT);
group_netpbmOutput.setLayoutData(formData);
group_netpbmOutput.setFont(font_group);
group_netpbmOutput.setText("Netpbm output");

//init Label
labelImage_netpbmOutput.setBackgroundImage(new Image(...));

//init ScrollComposite
scroll_netpbmOutput.setLayout(new FillLayout());
scroll_netpbmOutput.setContent(labelImage_netpbmOutput);

編集：バズの答えに対する反応

それは機能しますが...画像は次のように表示されます（「stackoverflow」は1つだけである必要があります）：

final private static Group group_netpbmOutput = new Group(shell, SWT.NONE);
final private static ScrolledComposite scroll_netpbmOutput = new ScrolledComposite(group_netpbmOutput, SWT.V_SCROLL | SWT.H_SCROLL);
final private static Label labelImage_netpbmOutput = new Label(scroll_netpbmOutput, SWT.BORDER);

group_netpbmOutput.setLayout(new GridLayout());
formData = new FormData(((FormData)group_options.getLayoutData()).width, 200);
formData.top = new FormAttachment(group_options, 50, SWT.BOTTOM);
formData.left = new FormAttachment(group_options, 0, SWT.LEFT);
group_netpbmOutput.setLayoutData(formData);
group_netpbmOutput.setFont(font_group);
group_netpbmOutput.setText("Netpbm output");

labelImage_netpbmOutput.setBackgroundImage(new Image(...));

scroll_netpbmOutput.setLayout(new GridLayout(1, false));
scroll_netpbmOutput.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));

scroll_netpbmOutput.setContent(labelImage_netpbmOutput);
scroll_netpbmOutput.setExpandHorizontal(true);
scroll_netpbmOutput.setExpandVertical(true);
scroll_netpbmOutput.setMinSize(labelImage_netpbmOutput.computeSize(SWT.DEFAULT, SWT.DEFAULT));
