[comp.sys.mac.hypercard] Hypertalk line drawing

bernard@boulder.Colorado.EDU (Bernie Bernstein) (01/07/89)

I am writing a stack in which buttons and fields are created and moved
around.  I would like to add lines connecting these boxes.

So far the only way that I have been able to draw lines is using
the CHOOSE {LINE,PENCIL,BRUSH} TOOL command followed by a DRAG.  This 
works, but is very slow.  Anytime, I move a box, the line needs to be
re-drawn using the inverse color, and redrawn after the box is
finished moving.  This is very slow, and I am now looking for a way to
speed up this process.

Does anyone have an XFCN or know of any method of drawing lines
quickly given the two endpoints (or endobjects).

Thanks in advance.
