rqt_bag.timeline_frame module

class rqt_bag.timeline_frame.TimelineFrame(*args: Any, **kwargs: Any)

Bases: QGraphicsItem

TimelineFrame Draws the framing elements for the bag messages (time delimiters, labels, topic names and backgrounds). Also handles mouse callbacks since they interact closely with the drawn elements

boundingRect()

cache_message(topic, t)

Updates the cache of message timestamps with a specific new message, bypassing any need to read entries from the bag.
