Re: [nebula-dev] Nebula Timeline Annotations

["philipcokonkwo@xxxxxxxxx" <philipcokonkwo@xxxxxxxxx>]

Hi,
So I have modified the timeline widget a bit to add custom annotations which I have been using in a project for about 3 months now. I will like to know if you are accepting PRs at the moment and the best way to go about it so as to be able to add this feature to the official timeline widget.

Best regards,Philip

 Hi Philip,

with 'custom modification' I mean that you would have to checkout the
source code and modify it to your needs. Depending on how you use the
timeline view (raw API / jface api) you would have to adapt the code.

A good starting point might be
https://github.com/eclipse/nebula/blob/master/widgets/timeline/org.eclipse.nebula.widgets.timeline/src/org/eclipse/nebula/widgets/timeline/figures/detail/track/lane/LaneFigure.java

which is the parent of each 'line' and holds the events to display

best regards
Christian
