How can I move the starting point of a FOC? (Focus of Control, is portrayed through narrow rectangles that adorn lifelines.)
When I create an Object in the sequence diagram, it will have a default FOC, which is started just under the object. And I have no way to move it. Even I move the message between 2 objects lower, it will only create 2 seperated FOC on the object's lifeline. And the first FOC still attach to the oject's rectangle.
If I can't move this starting point of FOC, then it means every object is created at the same time. That's no good. So please help me if you have this experience.
I read the help and search on the internet, just find somebody with the same problem: "Moving the top and bottom of focus-of-control rectangles. Sometimes I manage to move them by moving some messages. I've tried the business of holding down the Alt key while moving a message. I'm still in the dark about this. In particular, I'd like to get rid of the dangling tail of the FoC rectangle that always hangs down below the last outgoing message from that object."
