User Interactions

In VARCHART JGantt, user interactions such as create, delete and drag & drop activities, modify time scales and tables, collapse and expand groups of activities and many more are handled by the component. A programmer can react to those user interactions by registering specific events and can tailor the application to his customer's individual needs.

Page Preview and Printing
Printing capabilities of Gantt charts are included in the component allowing for zooming and and for scaling a diagram to page size, for paging and for page previews, for comfortable viewing and navigating.

Bars

Activities in a chart of Varchart JGantt can be displayed either by a variety of pre-defined bar shapes, or can be composed from the scratch. Any shape and pattern is available, even dynamic bars that actively grow or diminish to indicate the degree of completion of an activity. This animated picture shows a completion bar.

Grouping and Sorting in Gantt Charts

Activities in Gantt charts can be sorted and grouped after criteria. Group nodes can be defined and graphically accentuated in the Gantt graph as well as in the table.

Hierarchical Arrangement of Nodes
Nodes in Gantt charts can be arranged in a hierarchy by defining a hierarchy code. Display nodes on lower levels to be indented in the table. Lower level areas can interactively be collapsed and expanded.


Easy-To-Use Programming Interface
