QTimeline is a collection of Qt Widgets that draw a timeline similar to one you may find in common editorial software.
It does not implement much by itself. It has the concept of a keyframe and an errored frame however on their own, those don't mean much other than a coloured mark on the timeline.
This contains our main class, the TimelineWidget.
This contains our TimelineButtons class and our TimelineContiner class
This is a few buttons and their associated signals/slots that you may want to display with your TimelineWidget
This class acts mostly like a Controller linking the TimelineButtons and `TimelineWidget.
It also has minimal support for a playback loop via a QTimer at 30fps.
