Specifying the Message Width Spacing Restriction
When you want to restrict the mobility of any two Sequence diagram lifelines so that the width between them is the same as their message width, you can specify an automatically expanding space between the target lifelines by doing the following:
- At the top of the Sequence diagram, between the target lifelines, right-click the gray bar, and then choose Set Width to Message Width.
The IDE applies the restriction, and displays between the target lifelines a straight line with curved, vertical ends.
- To re-order Lifelines, simply drag a timeline to a new location.
