lbajardsilogic@0: \section model Data sources: the Model hierarchy
lbajardsilogic@0: 
lbajardsilogic@0:    A Model is something containing, or knowing how to obtain, data.
lbajardsilogic@0: 
lbajardsilogic@0:    For example, WaveFileModel is a model that knows how to get data
lbajardsilogic@0:    from an audio file; SparseTimeValueModel is a model containing
lbajardsilogic@0:    editable "curve" data.
lbajardsilogic@0: 
lbajardsilogic@0:    Models typically subclass one of a number of abstract subclasses of
lbajardsilogic@0:    Model.  For example, WaveFileModel subclasses DenseTimeValueModel,
lbajardsilogic@0:    which describes an interface for models that have a value at each
lbajardsilogic@0:    time point for a given sampling resolution.  (Note that
lbajardsilogic@0:    WaveFileModel does not actually read the files itself: it uses
lbajardsilogic@0:    AudioFileReader classes for that.  It just makes data from the
lbajardsilogic@0:    files available in a Model.)  SparseTimeValueModel uses the
lbajardsilogic@0:    SparseModel template class, which provides most of the
lbajardsilogic@0:    implementation for models that contain a series of points of some
lbajardsilogic@0:    sort -- also used by NoteModel, TextModel, and
lbajardsilogic@0:    SparseOneDimensionalModel.
lbajardsilogic@0: 
lbajardsilogic@0:    Everything that goes on the screen originates from a model, via a
lbajardsilogic@0:    layer (see below).  The models are contained in a Document object.
lbajardsilogic@0:    There is no containment hierarchy or ordering of models in the
lbajardsilogic@0:    document.  One model is the main model, which defines the sample
lbajardsilogic@0:    rate for playback.
lbajardsilogic@0: 
lbajardsilogic@0:    A model may also be marked as a "derived" model, which means it was
lbajardsilogic@0:    generated from another model using some transform (feature
lbajardsilogic@0:    extraction or effect plugin, etc) -- the idea being that they can
lbajardsilogic@0:    be re-generated using the same transform if a new source model is
lbajardsilogic@0:    loaded.
lbajardsilogic@0: 
lbajardsilogic@0: \section layer Things that can display data: the Layer hierarchy
lbajardsilogic@0: 
lbajardsilogic@0:    A Layer is something that knows how to draw parts of a model onto a
lbajardsilogic@0:    timeline.
lbajardsilogic@0: 
lbajardsilogic@0:    For example, WaveformLayer is a layer which draws waveforms, based
lbajardsilogic@0:    on WaveFileModel; TimeValueLayer draws curves, based on
lbajardsilogic@0:    SparseTimeValueModel; SpectrogramLayer draws spectrograms, based on
lbajardsilogic@0:    WaveFileModel (via FFTModel).
lbajardsilogic@0: 
lbajardsilogic@0:    The most basic functions of a layer are: to draw itself onto a
lbajardsilogic@0:    Pane, against a timeline on the x axis; and to permit user
lbajardsilogic@0:    interaction.  If you were thinking of adding the capability to
lbajardsilogic@0:    display a new sort of something, then you would want to add a new
lbajardsilogic@0:    layer type.  (You may also need a new model type, depending on
lbajardsilogic@0:    whether any existing model can capture the data you need.)
lbajardsilogic@0:    Depending on the sort of data in question, there are various
lbajardsilogic@0:    existing layers that might be appropriate to start from -- for
lbajardsilogic@0:    example, a layer that displays images that the user has imported
lbajardsilogic@0:    and associated with particular times might have something in common
lbajardsilogic@0:    with the existing TextLayer which displays pieces of text that are
lbajardsilogic@0:    associated with particular times.
lbajardsilogic@0: 
lbajardsilogic@0:    Although layers are visual objects, they are contained in the
lbajardsilogic@0:    Document in Sonic Visualiser rather than being managed together
lbajardsilogic@0:    with display widgets.  The Sonic Visualiser file format has
lbajardsilogic@0:    separate data and layout sections, and the layers are defined in
lbajardsilogic@0:    the data section and then referred to in the layout section which
lbajardsilogic@0:    determines which layers may go on which panes (see Pane below).
lbajardsilogic@0: 
lbajardsilogic@0:    Once a layer class is defined, some basic data about it needs to be
lbajardsilogic@0:    set up in the LayerFactory class, and then it will appear in the
lbajardsilogic@0:    menus and so on on the main window.
lbajardsilogic@0: 
lbajardsilogic@0: \section view Widgets that are used to show layers: The View hierarchy
lbajardsilogic@0: 
lbajardsilogic@0:    A View is a widget that displays a stack of layers.  The most
lbajardsilogic@0:    important subclass is Pane, the widget that is used to show most of
lbajardsilogic@0:    the data in the main window of Sonic Visualiser.
lbajardsilogic@0: 
lbajardsilogic@0:    All a pane really does is contain a set of layers and get them to
lbajardsilogic@0:    render themselves (one on top of the other, with the topmost layer
lbajardsilogic@0:    being the one that is currently interacted with), cache the
lbajardsilogic@0:    results, negotiate user interaction with them, and so on.  This is
lbajardsilogic@0:    generally fiddly, if not especially interesting.  Panes are
lbajardsilogic@0:    strictly layout objects and are not stored in the Document class;
lbajardsilogic@0:    instead the MainWindow contains a PaneStack widget (the widget that
lbajardsilogic@0:    takes up most of Sonic Visualiser's main window) which contains a
lbajardsilogic@0:    set of panes stacked vertically.
lbajardsilogic@0: 
lbajardsilogic@0:    Another View subclass is Overview, which is the widget that
lbajardsilogic@0:    contains that green waveform showing the entire file at the bottom
lbajardsilogic@0:    of the window.
