bool NoteLayer::snapToFeatureFrame ( View v,
int &  frame,
size_t &  resolution,
SnapType  snap 
) 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). 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.

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.

virtual ColourSignificance SingleColourLayer::getLayerColourSignificance (  )  const [inline, virtual, inherited]

This should return the degree of meaning associated with colour in this layer.

If ColourAbsent, the layer does not use colour. If ColourIrrelevant, the layer is coloured and the colour may be set by the user, but it doesn't really matter what the colour is (for example, in a time ruler layer). If ColourDistinguishes, then the colour is used to distinguish this layer from other similar layers (e.g. for data layers). If ColourAndBackgroundSignificant, then the layer should be given greater weight than ColourDistinguishes layers when choosing a background colour (e.g. for waveforms). If ColourHasMeaningfulValue, colours are actually meaningful -- the view will then show selections using unfilled rectangles instead of translucent filled rectangles, so as not to disturb the colours underneath.

Set a property using a fuzzy match.

Compare nameString with the property labels and underlying names, and if it matches one (with preference given to labels), try to convert valueString appropriately and set it. The valueString should contain a value label for value properties, a mapped value for range properties, "on" or "off" for toggle properties, a colour or unit name, or the underlying integer value for the property.

Note that as property and value labels may be translatable, the results of this function may vary by locale. It is intended for handling user-originated strings, _not_ persistent storage.

The default implementation should work for most subclasses.

If vertical zooming is not available, return 0.

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.

Convert this exportable object to XML in a string.

The default implementation calls toXml and returns the result as a string. Do not override this unless you really know what you're doing.
