#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 "apply the current legend visibility to the open tracks" control. Symmetric, so it carries whichever value the track currently shows. showLegendCheckboxItem takes this as its pin. |
