track-body.hpp File Reference

Go to the source code of this file.

Description

This helper class serves to manage the layout and display of the horizontally extended space of a "track" within the timeline.

Actually, this space is just a working area and created by custom drawing on the timeline canvas; yet for coordination of a globally consistent timeline layout, each track display is coordinated by a TrackPresenter, which corresponds to a session::Fork and directly controls the respective display elements in the header pane and the display of the timeline body; the latter is actually a canvas for custom drawing.

Todo:

as of 3/2023 the reworked Timeline-UI is basically complete
