DensityBandMixin

Auto-generated @jbrowse/mobx-state-tree API for the current JBrowse release — see pluggable elements for concepts. Provided by the canvas plugin. View source.

The density band: where the cursor is over it, what it draws, what it reads out, and the three foundation getters the band stands in for the too-large banner in.

Composes DensityTierMixin rather than sitting beside it, because the swap it decides is what every getter here keys off — a display taking the band takes the tier, in that order, and cannot compose them the wrong way round. A display with its own stand-in for the banner takes the tier alone, which is what LinearAlignmentsDisplay does.

Composed after the fetch foundation, whose displayPhase / svgReady it post-processes — types.compose resolves a collision to the later argument.

The two displays drawing a band compose it: LinearBasicDisplay's base model and LinearMultiRowFeatureDisplay, which had the block written out line for line.

Members a composed model contributes are listed here too, so these tables are the whole surface.
