wolfhece._drowning_manager

Drowning-victim companion object for WolfMapViewer.

All drowning-simulation management logic lives here. WolfMapViewer holds a single instance as self._drowning and exposes one-line delegators so that external callers remain unaffected.

Design notes

• DrowningManager owns the active_drowning reference, the mydrownings list, and all menu state (menudrowning hierarchy + check-item references).

• The wx parent for dialogs and menus is always self._viewer.

• menu_build() is idempotent — the first call creates and appends the “Drowning” menu to the menubar; subsequent calls are no-ops.

• on_menu() is bound to the wx menu and dispatches all drowning commands.

• new_drowning() handles both “Create” and “Add” from the object toolbar.

• register() is called from WolfMapViewer.add_object to record a newly created Drowning_victim_Viewer instance and update the active reference.

Module Contents

class wolfhece._drowning_manager.DrowningManager(viewer: wolfhece.PyDraw.WolfMapViewer)

Companion object that owns drowning-victim simulation state.

Instantiated once as viewer._drowning = DrowningManager(viewer) inside WolfMapViewer.__init__.

_viewer

mydrownings: list[wolfhece.drowning_victims.drowning_class.Drowning_victim_Viewer] = []

active: Drowning_victim_Viewer | None = None

_menu: wx.Menu | None = None

_menu_plot: wx.Menu | None = None

_item_plot_runs: wx.MenuItem | None = None

_item_plot_cells: wx.MenuItem | None = None

_item_plot_kde: wx.MenuItem | None = None

register(newobj: wolfhece.drowning_victims.drowning_class.Drowning_victim_Viewer) → None

Add newobj to the registry and make it the active drowning.

menu_build() → None

Create and append the ‘Drowning’ menu to the viewer menubar.

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