Overview of JViews Gantt Web features
The JViews Web technology is organized hierarchically, with a common layer providing the basic infrastructure (JViews basic Web applications) followed by the JViews Charts Web capabilities, which are the base for the JViews Gantt Web capabilities.
The basic infrastructure of the JViews Web technology is implemented by encoding the JViews graphic view into a raster image by the servlet (server-side); this image is then sent to the client-side for display. Every interaction performed on the client-side is mapped into requests to the servlet, which might respond with an image update. The JViews basic Web application layer provides the support for displaying and interacting with graphic views at the
IlvManagerView level, while the Gantt and Schedule views are based on
IlvGanttChart and
IlvScheduleChart.
The servlet processing the client requests and responding with image updates is also known as an
image servlet as its main purpose is to encode a raster image as a response to certain client requests. The common infrastructure is based on the manager view (
IlvManagerView) while the Gantt chart implementation is based on
IlvGanttChart and the Schedule chart implementation is based on
IlvScheduleChart.
The following basic functions are available on the Web browser:
View interactions: provide the ability to pan, zoom in and zoom out the Gantt or Schedule view
Object interactions: provide the ability to select Gantt or Schedule elements
Actions: trigger client and server actions through buttons, menus and interactions
Message box: a text area to display custom messages
