<bmx-gantt>
A project plan.
The dates are worked out, not typed. Each task has a duration and links; the chart schedules
them against the working calendar — weekends and the two holidays here — and draws the tasks with no
room to slip as the critical path. Drag a bar, its end or its progress grip, or draw a link from the dot at a
bar's end to another bar, and everything that depends on it moves with it.
Every edit is a cancelable event.
bmxTaskChange and bmxLinkChange
carry the whole list as it would be; call preventDefault() to refuse one, or set
apply-changes="false" and assign the lists yourself. canChange refuses a drag while it
is still in the reader's hand.
Tab into the task list once, then use the keyboard. The arrows move between rows,
→ and ← open and close a summary, F2 edits a cell,
Shift+→ moves a task a working day and Ctrl+Shift+→
lengthens it. Links are typed in the Predecessors column —
2, 3SS+1 — so nothing the
pointer can do needs a pointer.
