Mirrors MC's panel.c:4080-4197 mouse handling. Wraps the
Tui screen in termion's MouseTerminal (enables GPM on Linux /
xterm mouse on others — without it mouse events never reach
ratatui). The translate_mouse function maps termion MouseEvent
to a MouseAction enum that the FileManager dispatches as
cursor moves / entries / scroll (deferring HistoryPrev/Next/
List and ToggleHidden which need dedicated Cmds not yet in
the keymap).
New APIs:
- terminal::event::translate_mouse(event, panel_top,
panel_height, panel_width) -> MouseAction
- terminal::event::MouseAction (Click, DoubleClick,
ScrollUp/Down, HistoryPrev/Next/List, ToggleHidden,
Unhandled)
- FileManager::handle_mouse_event(m, size) routes
MouseAction to existing cursor_up_n / cursor_down_n /
Panel::enter / Panel::set_cursor helpers.
- app.rs routes TermEvent::Mouse through handle_mouse_event
before the keyboard-dispatch path.
Tests (9 new in terminal::event::mouse_tests):
- click_on_file_row_emits_click_action
- click_below_panel_is_unhandled
- click_on_header_history_prev_button (col 1)
- click_on_header_history_next_button (col width-2)
- click_on_header_toggle_hidden_button (col width-6)
- scroll_up_emits_scroll_up
- scroll_down_emits_scroll_down
- click_on_column_name_row_is_unhandled (sort-by-column
not yet wired)
- click_respects_panel_top_offset (panel_top parameter
works for menu-bar offset)
