canvas = new Canvas(composite, SWT.NONE);
canvas.addPaintListener(new PaintListener() {
            public void paintControl(PaintEvent e) {
                if(image!=null)
                    e.gc.drawImage(image, 0, 0);
            }
        });
2、新建Image，调用canvas.redraw()方法
Image image = new Image(display,"C:/eclipse/plugins/org.eclipse.platform_2.0.2/eclipse_lg.gif");
canvas.redraw();


另外还有一种更加简单的方法可以显示图片，通过设置Label的setImage方法显示图片

Label label = new Label(shell, SWT.NONE);
label.setImage(new Image(Display.getDefault(), "c:/abc.gif"));

        switch (iIndex) {
            case 0: {
                if(grpExpression.getLayoutData() instanceof GridData) {
                    GridData gd = (GridData)grpExpression.getLayoutData();
                    gd.heightHint = -1;
                    grpExpression.setLayoutData(gd);

                    GridData gd = (GridData)grpExpression.getLayoutData();
                    gd.heightHint = -22;  //设成非-1的任何小于0的值即可
                    grpExpression.setLayoutData(gd);
                    grpExpression.layout(true);
                    rootComposit.layout(true);
                }
                grpObject.setVisible(true);
                break;
            }
        }

    上例中grpExpression位于布局中段，grpObject位于布局末尾
