SWT Composite出现在右侧

Question

我正在为eclipse开发一个带有视图的插件，我需要使这个视图可滚动。我发现了如何使其可滚动，但复合材料出现在视图的右侧。如何填写所有视图？

我的代码：

public class Comp2 extends Composite {

    public Comp2(Composite parent, int style) {
        super(parent, SWT.NONE);

        final ScrolledComposite sc = new ScrolledComposite(parent, SWT.H_SCROLL | SWT.V_SCROLL);
        sc.setLayout(new FillLayout());
        sc.setExpandHorizontal(true);
        sc.setExpandVertical(true);

        final Composite subContainer = new Composite(sc, SWT.NONE);

        Button btnNewButton = new Button(subContainer, SWT.NONE);
        btnNewButton.setBounds(75, 99, 90, 30);
        btnNewButton.setText("New Button");

        Button btnNewButton_1 = new Button(subContainer, SWT.NONE);
        btnNewButton_1.setBounds(357, 398, 90, 30);
        btnNewButton_1.setText("New Button");

        sc.setContent(subContainer);

        sc.addControlListener(new ControlAdapter() {

            @Override
            public void controlResized(ControlEvent e) {
                Rectangle r = sc.getClientArea();
                sc.setMinSize(subContainer
                        .computeSize(r.width, SWT.DEFAULT));
            }
        });
    }

    @Override
    protected void checkSubclass() {
        // Disable the check that prevents subclassing of SWT components
    }
}

由于您正在扩展Composite，因此复合材料正在将其正常主体添加到父级。然后，您将ScrolledComposite添加到父级，使其与第一个复合材料并排放置。

您可以通过更改其父级ScrollComposite将Composite置于super(parent, SWT.NONE); // This composite needs a layout setLayout(new FillLayout()); // Parent of the ScrolledComposite is this Composite ScrolledComposite sc = new ScrolledComposite(this, SWT.H_SCROLL | SWT.V_SCROLL); 内：
