test24.c

安装DDD之前

/** $Header: /cvsroot/lesstif/lesstif/test/Xm/rowcolumn/test24.c,v 1.7 2001/05/15 14:46:10 amai Exp $
    -- vertical tight layout of widgets with XmNadjustLast = False.

    resulting layout should be something like this:

    button1
    button2
    button3
    button4
    button5

    resizing smaller will yield something like this:

    button1 button4
    button2 button5
    button3
