class exlab_wizard.ui.components.breadcrumb.BreadcrumbSegment(label, node_id)[source]#

Bases: object

One clickable segment in the breadcrumb bar.

Parameters:

label (str)
node_id (str)

label: str#

node_id: str#: Tree node id the segment selects when clicked.

exlab_wizard.ui.components.breadcrumb.render_breadcrumb(*, selected_node, on_navigate=None)[source]#

Render the breadcrumb row. Pure render function.

Each segment is a clickable label; the callback receives the segment’s node_id so the caller can re-emit selection through the standard on_select_node handler (Redesign §9.1).

Parameters:

selected_node (str | None)
on_navigate (Callable[[str], None] | None)

Return type:

Any

exlab_wizard.ui.components.breadcrumb.segments_from_node_id(selected_node)[source]#

Decompose a tree-node id into clickable segments.

Tree ids are slash-joined strings (equip/proj/Runs/Run_...). The leading device label is conceptually the root; we don’t render it explicitly here. Returns a left-to-right list of segments where each segment’s node_id is the ancestor id needed to navigate to it.

Parameters:: selected_node (str | None)
Return type:: list[BreadcrumbSegment]
