新手求解惑 axlGRPDrwRectangle参数问题

mycoal

各位路过的大神，请问一下这个画矩形的函数，后面的这个坐标参数这么写有问题吗？还有就是前面的参数handle到底该写啥？看了帮助文件知道是定义图形类型为矩形的，但是到底该写什么呢？
axlCmdRegister("hello",'hello)
defun( hello ()

axlGRPDrwRectangle(handle '(-1000 1000) '(1000 1000)))

)

————————————————————————
我想实现的功能是在一个圆内，从中心点开始以一定间距拼矩形，初始的矩形是有的，其实最方便的是复制，不过为了后面判断矩形是否在圆内，所以想采用两点的方法来画矩形。现在是画第一个矩形，skill用过没接触过怎么写，见笑~

这个帖子有看到，里面列了很多专有的函数，axlGRPDrwRectangle也在列不过没有注释。

你需要的函数是
axlDBCreateRectangle()

axlDBCreateRectangle(
l_bBox
[g_fill]
[t_layer]
[t_netname]
[o_parent]
)
⇒ l_result/nil

Arguments
l_bBox Bounding box of the rectangle: Lower left and upper right corners
of rectangle
g_fill If t then the fill is solid. If nil (default) then the rectangle is
unfilled.
t_layer Layer to which to add the rectangle. Default is the active layer.
t_netname Name of net to which the rectangle is to belong. This argument
is meaningful only if the rectangle is being added on an Etch
layer.

o_parent dbid of object of which the rectangle is to be a part. Use either
the dbid of a symbol instance or use nil to specify the design
itself.

axlGRPDrwRectangle   需要   axlGRPDrwInit   初始化

axlGRPDrwInit
axlGRPDrwInit(
r_form
t_field
t_func
)
⇒ r_graphics/nil

Description
Sets up necessary data structures for triggering the graphics callback into the graphics field.
Arguments
r_form Handle of the form.
t_field Name of field into which the package should draw. (Only
THUMBNAIL fields are supported.)
t_func Name of the drawing callback function. Callback function is
invoked with the graphics handle as the parameter.
Value Returned
r_graphics Graphics package handle.
nil Failed to set up necessary data structures for triggering the
graphics callback due to invalid arguments.

axlGRPDrwInit

就是要先运行 axlGRPDrwInit来得到r_graphics这个参数的意思吗？谢谢！没人指教一下，这些浅显的东西看资料也很难看明白我再去研究一下axlGRPDrwInit这个函数。
