Constructor & Destructor Documentation

TrackPresenter()

TrackPresenter ( ID  id, ctrl::BusTerm &  nexus, DisplayViewHooks &  displayAnchor  )

inline

Parameters

Member Function Documentation

buildMutator()

void buildMutator ( lib::diff::TreeMutator::Handle  buffer )

inlineoverridevirtual

set up a binding to respond to mutation messages via UiBus

Note

we distinguish between the contents of our four nested child collections based on the symbolic type field sent in the Record type within the diff representation

• "Marker" designates a Marker object
• "Clip" designates a Clip placed on this track
• "Fork" designates a nested sub-track
• "Ruler" designates a nested ruler (timescale, overview,....) belonging to this track

See also

TimelineController::buildMutator() for a basic explanation of the data binding mechanism
