SWT如何控制堆栈式面板之间的跳转

Answer 1

StackLayout mainsl = new StackLayout();
mainsl.topControl = 要显示的容器;

例
Composite main = new Composite(parent, SWT.NONE);

//将main 设置为堆栈布局
StackLayout mainsl = new StackLayout();
main.setLayout(mainsl);

//在main容器上创建3个
Composite sub1=new Composite(main, SWT.NONE);
Composite sub2=new Composite(main, SWT.NONE);
Composite sub3=new Composite(main, SWT.NONE);

mainsl.topControl = sub1;// 首先显示sub1面板

某个监听事件中，mainsl.topControl = sub2;即会显示sub2面板

Answer 2

比如一个StackLayout sk = new StackLayout();

sk.topControl = compArray[x];//compArray为包含所有面板引用的数组，
//x为要显示面板在数组中的索引
然后
sk.layout()一下就OK了
