Detailed Description

Thin strip between toolbar and canvas showing one chip per active filter.

Hidden when no filters are active. Each chip carries a label and a × button. Clicking × emits chipCloseRequested(barIndex, scope) BEFORE any chip is removed. The receiver (MainWindow) orchestrates graph state restoration, then calls removeChipAt() or rebuilds the bar via clearAllChips() + addChip(). "Clear all" emits clearAllRequested(); MainWindow drains the stack, then calls clearAllChips().

Menu-driven restores (Restore All Nodes / Restore All Edges) must call removeLatestChipForScope() / removeAllChipsForScope() so the bar stays in sync.

addChip()

void FilterBarWidget::addChip	(	const QString &	label,
		FilterCondition::Scope	scope )

chipCloseRequested

void FilterBarWidget::chipCloseRequested ( int barIndex, FilterCondition::Scope scope )

signal

Emitted when the user clicks × on a chip, BEFORE the chip is removed. barIndex is the chip's position (0 = leftmost) at the time of the click. The bar does NOT remove the chip automatically; the receiver must call removeChipAt(), clearAllChips(), or rebuild the bar as appropriate.
