Scrolling behavior for UML sequence diagrams [message #238330]

Hi,

I'm using GEF/Draw2d to visualize UML sequence diagrams. I would like to
make it so the lifeline heads remain on the top of the diagram when the user
scrolls down. However, since the number of lifelines can span more than one
screen width, behavior for scrolling across should not be changed. This
situation is analogous to the scrolling behavior of column headings in a
spreadsheet.

What would be the best way to accomplish this in GEF/Draw2d? My
implementation currently uses a ScrollingGraphicalViewer. Any assistance
would be greatly appreciated.

Thanks,

Jeff
