void TimeValueLayer::paint ( LayerGeometryProvider *  , QPainter &  , QRect    ) const

overridevirtual

Paint the given rectangle of this layer onto the given view using the given painter, superimposing it on top of any existing material in that view.

The LayerGeometryProvider (an interface implemented by View) is provided here because it is possible for one layer to exist in more than one view, so the dimensions of the view may vary from one paint call to another (without any view having been resized).

Implements Layer.

bool TimeValueLayer::snapToFeatureFrame ( LayerGeometryProvider *  , sv_frame_t &  , int &  resolution, SnapType  , int    ) const

overridevirtual

Adjust the given frame to snap to the nearest feature, if possible.

If snap is SnapLeft or SnapRight, adjust the frame to match that of the nearest feature in the given direction regardless of how far away it is. If snap is SnapNeighbouring, adjust the frame to that of the nearest feature in either direction if it is close, and leave it alone (returning false) otherwise. SnapNeighbouring should always choose the same feature that would be used in an editing operation through calls to editStart etc.

If ycoord is non-negative, it contains the y coordinate at which the interaction that prompts this snap is taking place (e.g. of the mouse press used for a selection action). Layers that have objects at multiple different heights may choose to use this information. If the current action has no particular y coordinate associated with it, ycoord will be passed as -1.

Return true if a suitable feature was found and frame adjusted accordingly. Return false if no suitable feature was available (and leave frame unmodified). If returning true, also return the resolution of the model in this layer in sample frames.

bool TimeValueLayer::snapToSimilarFeature ( LayerGeometryProvider *  , sv_frame_t &  , int &  resolution, SnapType    ) const

overridevirtual

Adjust the given frame to snap to the next feature that has "effectively" the same value as the feature prior to the given frame, if possible.

The snap type must be SnapLeft (snap to the time of the next feature prior to the one preceding the given frame that has a similar value to it) or SnapRight (snap to the time of the next feature following the given frame that has a similar value to the feature preceding it). Other values are not permitted.

Return true if a suitable feature was found and frame adjusted accordingly. Return false if no suitable feature was available (and leave frame unmodified). If returning true, also return the resolution of the model in this layer in sample frames.

This should return true if the layer can safely be scrolled automatically by a given view (simply copying the existing data and then refreshing the exposed area) without altering its meaning.

For the view widget as a whole this is usually not possible because of invariant (non-scrolling) material displayed over the top, but the widget may be able to optimise scrolling better if it is known that individual views can be scrolled safely in this way.

Get the number of vertical zoom steps available for this layer.

If vertical zooming is not available, return 0. The meaning of "zooming" is entirely up to the layer – changing the zoom level may cause the layer to reset its display extents or change another property such as display gain. However, layers are advised for consistency to treat smaller zoom steps as "more distant" or "zoomed out" and larger ones as "closer" or "zoomed in".

Layers that provide this facility should also emit the verticalZoomChanged signal if their vertical zoom changes due to factors other than setVerticalZoomStep being called.

inlinevirtualinherited

Return the ID of a model representing the contents of this layer in a form suitable for export to a tabular file format such as CSV.

In most cases this will be the same as returned by getModel(). The exceptions are those layers such as SpectrogramLayer, that are "only" alternative views of time-domain sample data. For such layers, getModel() will return the backing time-domain data, for example as a ReadOnlyWaveFileModel; but getExportModel() will return a model, possibly "local to" the layer, which adapts this into the form shown in the layer for a given view so that the export matches the layer's visible contents.

Because this is supposed to match the contents of the view rather than the backing model, it's necessary to pass in a view (or LayerGeometryProvider) so that the layer can retrieve its vertical extents for export.

virtual void Layer::setSynchronousPainting ( bool  )

Enable or disable synchronous painting.

If synchronous painting is enabled, a call to paint() must complete painting the entire rectangle before it returns. If synchronous painting is disabled (which should be the default), the paint() call may defer painting some regions if data is not yet available, by calling back on its view to schedule another update. Synchronous painting is necessary when rendering to an image. Simple layer types will always paint synchronously, and so may ignore this.
