Example #9 in the MetaCard example stack connects some buttons with lines
that you can manipulate with the mouse. I had this kind of functionality
in a program I created that let the user annotate pictures with text and
draw lines from the text to points on the picture to better illustrate
their point. They could click on and move either endpoint of the line if
they wanted to in my app.
If I remember correctly, I think it goes something like this:
set the points of graphic "foobarLine" to startx, starty, endx, endy
>>> >The "line" tool is a paint tool. There are no "draw" tools in
>>> >MetaCard. There is a "line" graphic style, though, which you can get
>>> >at with:
>>> >set the style of the templateGraphic to "line"
>>> >choose graphic tool
>>>
>>> Almost there. Adjusting the endpoints of the graphic does not seem
>>> possible, at least not in the manner users are accustomed for line
>>> objects.
>>
>>The object is always a rect, if that's what you mean. This
>>characteristic would be extremely difficult to change.
>>
>>> Any chance we'll see the line style have selection/interaction behaviors
>>> like standard line objects in drawing programs?

>>There's always a chance, but it'd be good to know exactly what's wrong
>>with the way it works now first.

>In drawing programs for Mac OS and Windows (can't think of an exception

>Dragging either of these handles adjusts that end point.
