[REBOL] Pane Refresh Problem

From: coussement::c::itc::mil::be at: 2-May-2001 11:29

Hi list:

For experimenting with /View, I've written another "Game of Life".

The algorithm works OK with an ASCII output, but I cannot get the result in
/view, because I don't know how to trigger a refresh of the pane.

Here's the code I use for the visual part - max-x and max-y are global words
setting the size of the life map.

show-visual: func [
    /local x y main society
][
    main: layout [
        vh2 "Game of Life"
        guide
        pad 20
        button "QUIT" [unview halt]
        return
        box 2x140 yellow
        return
        panels: box 300x300
    ]

    society: [
        origin 8x8
        backdrop black across space 1x1
        style alive box red 10x10
        style dead box black 10x10
        return
    ]

    forever [

        make-live   ;--- create the life map

        ;--- dynamically append boxes to pane
        for x 1 max-x 1 [
            for y 1 max-y 1 [
                either (alive? x y)[
                    append society 'alive
                ][
                    append society 'dead
                ]
            ]
            append society 'return
        ]

        panels/pane: layout society
        show panels/pane
        view main
    ]
]

</snip>

It works if I close the generated windowat each generation.
It's for sure not difficult, but I cannot find anything in the Doc :-(

Any idea ?
