| virtual ColourSignificance WaveformLayer::getLayerColourSignificance | ( | ) | const [inline, virtual] |
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.
