Pane

A pane is a single region of the tiled layout. It renders as a <bw-pane sash-id="…"> element and holds exactly one glass, which fills it with a header and content.

Concept

Panes come from the layout tree. Each leaf of the config becomes a pane; a node with children becomes a split, drawn as a draggable muntin (divider) between its two sides. Every pane carries a Sash ID — the identifier you pass to APIs like addPane, updatePane, and removePane to target it.

A pane is just the region; the glass is what fills it. Binary Window seeds each new pane with a glass built from that node's title, content, and actions.

Add, update, and remove

Panes are created by splitting an existing one and removed by collapsing back:

• Add — addPane splits a target pane, placing the new one to its top, right, bottom, or left.
• Update — updatePane changes a pane's size, position, or its glass title and content in place.
• Remove — removePane removes a pane; its sibling expands to fill the freed space.

Rearranging panes by dragging a glass, or resizing them by dragging a muntin, is handled for you — see Glass.
