anchoredCount()

std::size_t ml::AnchorManager::anchoredCount ( )

static

Number of objects with at least one anchor (test/introspection helper).

clear()

void ml::AnchorManager::clear ( Positionable * owner )

static

Drop all of owner's anchors (the unanchored() opt-out).

hasAnchors()

bool ml::AnchorManager::hasAnchors ( const Positionable * owner )

static

True if owner currently has any retained anchor.

recordBaseline()

void ml::AnchorManager::recordBaseline ( Positionable * owner )

static

Snapshot owner's current position as the baseline for external-move detection. Called right after a verb applies its op immediately.

release()

void ml::AnchorManager::release ( const Positionable * owner )

static

Remove owner's own anchors AND scrub any anchor (in any object) that references it. Called from ~Positionable so a destroyed object is never solved against or dangled.

set()

void ml::AnchorManager::set ( Positionable * owner, AnchorOp op, const Positionable * ref, float spacing )

static

Record/replace a retained anchor for owner. ref == nullptr anchors to the window. An op replaces any existing anchor with the same op, so repeated fill() calls don't accumulate.

solveAll()

void ml::AnchorManager::solveAll ( )

static

Re-solve every anchored object (called on window resize). Detaches externally-moved objects first, then iterates to a fixpoint.
