◆ paint()

void NoteLayer::paint ( View ,
QPainter &  ,
QRect   
) const
virtual

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 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).

◆ snapToFeatureFrame()

bool NoteLayer::snapToFeatureFrame ( View ,
int &  ,
int &  resolution,
SnapType   
) const
virtual

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 SnapNearest, adjust the frame to that of the nearest feature in either direction. If snap is SnapNeighbouring, adjust the frame to that of the nearest feature 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.

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.

◆ isLayerScrollable()

bool NoteLayer::isLayerScrollable ( const View ) const
virtual

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.

This should return true if the layer can be edited by the user.

Reimplemented from Layer.

Definition at line 96 of file NoteLayer.h.

◆ getCompletion()

virtual int NoteLayer::getCompletion ( View ) const
inlinevirtual

Return the proportion of background work complete in drawing this view, as a percentage – in most cases this will be the value returned by pointer from a call to the underlying model's isReady(int *) call.

The view may choose to show a progress meter if it finds that this returns < 100 at any given moment.

◆ getValueExtents()

bool NoteLayer::getValueExtents ( float &  min,

virtual

Return the minimum and maximum values for the y axis of the model in this layer, as well as whether the layer is configured to use a logarithmic y axis display.

Also return the unit for these values if known.

This function returns the "normal" extents for the layer, not necessarily the extents actually in use in the display.

Return the minimum and maximum values within the displayed range for the y axis, if only a subset of the whole range of the model (returned by getValueExtents) is being displayed.

Return false if the layer is not imposing a particular display extent (using the normal layer extents or deferring to whatever is in use for the same units elsewhere in the view).

Return false if not supported on this layer (and set nothing). In most cases, layers that return false for getDisplayExtents should also return false for this function.

◆ getVerticalZoomSteps()

int NoteLayer::getVerticalZoomSteps ( int &  ) const
virtual

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.

Reimplemented from Layer.

Definition at line 287 of file NoteLayer.cpp.

References m_model, and shouldAutoAlign().

◆ getCurrentVerticalZoomStep()

int NoteLayer::getCurrentVerticalZoomStep ( ) const
virtual

Get the current vertical zoom step.

A layer may support finer control over ranges etc than is available through the integer zoom step mechanism; if this one does, it should just return the nearest of the available zoom steps to the current settings.

Convert the layer's data (though not those of the model it refers to) into XML for file output.

This class implements the basic name/type/model-id output; subclasses will typically call this superclass implementation with extra attributes describing their particular properties.

Return true if this layer can handle zoom levels other than those supported by its zoom constraint (presumably less efficiently or accurately than the officially supported zoom levels).

Definition at line 81 of file Layer.h.

◆ setSynchronousPainting()

virtual void Layer::setSynchronousPainting ( bool  )
inlinevirtualinherited

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.

virtual bool Layer::snapToSimilarFeature ( View ,

inlinevirtualinherited

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 completely obscures any underlying layers.

It's used to determine whether the view can safely draw any selection rectangles under the layer instead of over it, in the case where the layer is not scrollable and therefore needs to be redrawn each time (so that the selection rectangle can be cached).

◆ setLayerDormant()

void Layer::setLayerDormant ( const View v,

virtualinherited

Indicate that a layer is not currently visible in the given view and is not expected to become visible in the near future (for example because the user has explicitly removed or hidden it).

The layer may respond by (for example) freeing any cache memory it is using, until next time its paint method is called, when it should set itself un-dormant again.

A layer class that overrides this function must also call this class's implementation.
