PatchbayWidget Class Reference

#include "stage/timeline/patchbay-widget.hpp"

Description

Header pane control area corresponding to a fork of nested tracks.

The structure of child tracks is built up recursively, starting with a single top level TrackHeadWidget corresponding to the »fork root«. The actual controls for the individual tracks are managed by those TrackHeadWidget elements, while the PatchbayWidget corresponds to the whole structure and is responsible for presenting the proper vertical scrolling, as dictated by the actual track content within the BodyCanvasWidget sitting at the right side of the HeaderPaneWidget (which is the enclosing container of this PatchbayWidget).

Constructor & Destructor Documentation

PatchbayWidget()

PatchbayWidget

(

PAdjustment const &

vScroll

)

Set up the patchbay area of the timeline UI.

The patchbay is a container to hold the actual placement control widgets arranged alongside with each track, according to the nested track structure. The header pane and thus especially the patchbay needs to follow as a slave to the vertical scrolling adjustments of the Timeline display; if the users scrolls up or down over the more or less expanded tree of tracks, the header has to follow this scrolled display in sync. Thus the implementation of the patchbay is based on a Gtk::Viewport, which is attached to the vertical Gtk::Adjustment, as exposed by the Gtk::ScrolledWindow holding the timeline body canvas on the right side of the Timeline UI.

Note

the Patchbay is not scrollable in horizontal direction, thus we create a disabled Adjustment for this parameter.
