Gantt Flow addon

Project root of the Gantt component addon, Flow integration for Vaadin 24 platform.

Multi-module Maven project with two modules: gantt-flow-addon and gantt-flow-demo.

• gantt-flow-addon contains add-on sources build into JAR deliverable.
• gantt-flow-demo contains demo application build into WAR package.

Example

Gantt gantt = new Gantt();
Step step = new Step();
step.setCaption("First Step");
step.setBackgroundColor("#9cfb84");
step.setStartDate(LocalDate.now().atTime(12, 0));
step.setEndDate(step.getStartDate().plusWeeks(1));
gantt.addStep(step);

Dependencies

Main component class org.vaadin.tltv.gantt.Gantt is a Java wrapper for tltv-gantt-element web component. This requires two dependecies:

• tltv-gantt-element (https://github.com/tltv/gantt-element)
• tltv-timeline-element (https://github.com/tltv/timeline-element).

Timeline element and gantt element depends on following libraries:

• Lit (https://lit.dev/)
• date-fns (https://github.com/date-fns/date-fns)
• date-fns-tz (https://github.com/marnusw/date-fns-tz)

Known issues

formatInTimeZone is not working in all cases (date-fns-tz 2.0.0). E.g. Gantt with "Europe/Berlin" time-zone shows wrong hour when run in Browser with "Europe/Helsinki" timezone.
