Constructor & Destructor Documentation

build a new timeline display and attach it to the UI-Bus.

Parameters

identity	used to refer to a corresponding element in the Session
trackID	the mandatory root track used in the associated Sequence
nexus	some established connection to the UI-Bus, will be used to register the embedded TimelineController as communication partner to respond under the given timeline ID.

Remarks: after creation, the widget can be hooked up and wired like any ordinary GTK element; it becomes passive and ready to receive signals. The active role is played by the controller, which also responds to mutation messages; this is the only way to populate the timeline display. Likewise, a timeline shall be deleted by sending a respective mutation message to its parent element, the one that created it, typically also in response to a message. Non the less it is possible just to delete a TimelineWidget, since it is a Gtk::Widget, and the controller is also sigc::trackable and additionally, as a stage::model::Tangible, it will deregister automatically from the UI-Bus. After that, any further messages towards this element will be dropped silently.
