#crossCuttingMixin A legend the user can turn off. A promotable showLegend
config slot, whose promotedBase sets whether this display type's legend is on
by default. Brings the resolved showLegend getter, the
showLegendDisplayTypeDefault pin showLegendCheckboxItem takes, and
setShowLegend
Six displays carried a character-identical copy of these three members —
alignments, Hi-C, multi-row features, multi-wiggle, the multi-sample variant
base and the shared LD model — reading and writing one slot name through the
promotable cascade. Both ends of that were already shared: the track-menu
row is showLegendCheckboxItem and the thing it shows is FloatingLegend, so
this was the middle link between two pieces of common code.
The config slot stays per display, and deliberately — promotedBase
legitimately differs (a Hi-C color scale is off by default, a variant genotype
key on) and each description describes a genuinely different legend. That
decision is showLegendCheckboxItem's docstring and this does not disturb it:
the slot is what the composing display still supplies, and the mixin only stops
it hand-writing the accessors over it.
setShowLegend is overridable, and one display overrides it: the multi-sample
variant base also clears dismissedLegendSections, since re-showing the whole
legend is what un-dismisses the sections inside it.
Getters
| Member | Description |
|---|---|
showLegendboolean | Whether the legend is drawn. Resolved through the promotable-slot tiers (resolveConf): an explicit track value customizes it either way, otherwise it follows the session-wide default for this display type, falling back to the slot's promotedBase. |
showLegendDisplayTypeDefaultPin | The "make the current legend visibility the default for all tracks" control. Symmetric, so it promotes whichever value the track currently shows. showLegendCheckboxItem takes this as its pin. |
