wolfhece._lidaxe_manager
========================

.. py:module:: wolfhece._lidaxe_manager

.. autoapi-nested-parse::

   Lidaxe (flow-accumulation / catchment delineation) companion for WolfMapViewer.

   All Lidaxe-related state and logic lives here.
   ``WolfMapViewer`` holds a single instance as ``self._lidaxe`` and exposes
   one-line delegators so external callers remain unaffected.

   Design notes
   ------------
   * ``LidaxeManager`` owns the ``active`` reference (the ``Lidaxe`` instance)
     and all menu state (``_menu`` hierarchy + item references).
   * The wx parent for dialogs is always ``self._viewer``.
   * ``menu_build()`` is idempotent — the first call creates and appends the
     'Lidaxe' menu to the menubar; subsequent calls are no-ops.
   * ``on_menu()`` is bound to the wx menu and dispatches all Lidaxe commands.
   * ``activate()`` creates the ``Lidaxe`` instance and calls ``menu_build()``.





Module Contents
---------------

.. py:class:: LidaxeManager(viewer: wolfhece.PyDraw.WolfMapViewer)

   Companion object that owns Lidaxe state for WolfMapViewer.

   Instantiated once as ``viewer._lidaxe = LidaxeManager(viewer)`` inside
   ``WolfMapViewer.__init__``.

   .. py:method:: activate() -> None

      Create a Lidaxe instance and build the menu (idempotent).



   .. py:method:: menu_build() -> None

      Create and append the 'Lidaxe' menu to the viewer menubar.

      Safe to call multiple times — only the first call has any effect.
