public class JsonSearchBar extends JPanel
A compact search bar that drives text highlighting in the raw pane and match navigation in the tree pane.

Layout

  [ Search: ][______________text field______________][ ▲ ][ ▼ ][ ✕ ][ 3 of 12 ]

The bar is placed in the SOUTH slot of the JsonSplitPane below both content panes so it spans the full width and is always visible.

Behaviour

  • Typing in the field immediately highlights all matching spans in the raw pane via JsonRawPane#highlight(String) and filters the tree to show only matching paths via JsonTreePane.search(String).
  • The ▲ / ▼ buttons (and F3 / Shift+F3 key bindings) navigate between raw-pane highlights.
  • The ✕ button clears the query and removes all highlights.
  • The match count label ("3 of 12") is updated after every search by a callback from JsonRawPane.
  • The field background turns a muted red when there are no matches, normal dark when there are matches or the field is empty.

Threading

All callbacks arrive and all mutations happen on the EDT.
