如何探测rebol布局，但只是获得原始规格

Question

我们来看看：

panel1: layout [
    origin 8x8
    h2 "Panel 1"
    field "Field 1"
    field "Field 2"
    button "The Answer" [alert "I know nothing."]
]

如果我探测panel1，我得到了一堆行，而我想得到原始块：

[
        origin 8x8
        h2 "Panel 1"
        field "Field 1"
        field "Field 2"
        button "The Answer" [alert "I know nothing."]
    ]

如何获得这个？

Answer 1

您应该只使用另一个字来保存块值：

panel1: layout panel-def: [
    origin 8x8
    h2 "Panel 1"
    field "Field 1"
    field "Field 2"
    button "The Answer" [alert "I know nothing."]
]

probe panel-def

因为布局函数返回具有大量默认值的面对象。顺便用？而不是探测器，因为在面对象中可以有自引用，因此您将拥有无限的探测输出。
