Question

我是swt的新手。在eclipse插件中，我创建了包含一些代码的视图，如下所示。

public void createPartControl(final Composite parent) {

Composite outer = new Composite(parent, SWT.BORDER);
    outer.setBackground(new Color(null, 207, 255, 206)); // Green

    FormLayout formLayout = new FormLayout();
    formLayout.marginHeight = 5;
    formLayout.marginWidth = 5;
    formLayout.spacing = 5;
    outer.setLayout(formLayout);
    //TOP
    Composite Top = new Composite(outer, SWT.BORDER);
    Top.setLayout(new GridLayout());
    Top.setBackground(new Color(null, 232, 223, 255)); // Blue

    FormData fData = new FormData();
    fData.top = new FormAttachment(0);
    fData.left = new FormAttachment(0);
    fData.right = new FormAttachment(100); // Locks on 10% of the view
    fData.bottom = new FormAttachment(20);
    Top.setLayoutData(fData);

    //BOTTOM
    Composite Bottom = new Composite(outer, SWT.BORDER);
    Bottom.setLayout(fillLayout);
    Bottom.setBackground(new Color(null, 255, 235, 223)); // Orange

    fData = new FormData();
    fData.top = new FormAttachment(20);
    fData.left = new FormAttachment(0);
    fData.right = new FormAttachment(100);
    fData.bottom = new FormAttachment(100);
    Bottom.setLayoutData(fData);

Bottom Composite包含一些标签，在mouseListener的mouseDown上，应该重绘整个页面。我使用了dispose，但页面是空的，但它不再创建。如何重绘或刷新主要父级。

标签代码如下所示：

    Label label = new Label(Bottom, SWT.NONE);
    label.addMouseListener(new MouseListener() {

        @Override
        public void mouseUp(MouseEvent arg0) {
        }

        @Override
        public void mouseDown(MouseEvent arg0) {
             for (Control kid : parent.getChildren()) {
                      kid.dispose();
                    }

            //Need to create/redraw th layout here
        }

        @Override
        public void mouseDoubleClick(MouseEvent arg0) {
        }
    });

Answer 1

在父Composite上调用layout（）方法

单击鼠标刷新整个复合/视图
