A large swt widget component shall be implemented. A gantt diagram may
be an example for this component:
- a small part is visible, horizontal and vertical scrollbars are used
to scroll to currently invisible areas
- the number of horizontal and vertical elements is dynamic
- any (visible) element is choosable and shows a context menu
Simply implementing a paint listener may have poor performance if there
are many elements in the invisible are. Also the scrollbars shall
support smooth scrolling.
In which way can such component be implemented?
