fix(gui): stop row menus drawing unusable entries blurred by donislawdev · Pull Request #204 · donislawdev/BeanNetworkTester

Summary

In the row menus of the Sockets and Port check tables, an entry that does not apply to
the clicked row (for example "Target this process" on a free port) was drawn blurred,
and brighter than a live entry. The connection table had the same code.
Cause, from Tk's own source (win/tkWinMenu.c, DrawMenuEntryLabel): on Windows a
disabled label is drawn twice, first in the system 3-D highlight colour at (+1, +1),
then in -disabledforeground. No menu or entry option turns the first pass off, so
no colour choice could fix it.
New component theme.set_menu_entry_available(menu, index, available): the entry stays
in the normal state and is coloured inert (DIS_FG text, a subtle LINE_C hover so
keyboard navigation still shows where it is). Going back to usable hands every colour
back to the menu. The three row menus (conns.py, sockets.py, portcheck.py) use it;
they are the only places that ever greyed out a menu entry.
Every command behind these entries already checks the row, so a click on an inert entry
does nothing.
Trade-off: a screen reader reports an inert entry as available, since only Tk's disabled
state carries that. Hiding the entries instead would change the menu's shape per row.

Verification

Real Tk 9.0.4 and 8.6.15, a probe that posts the styled menu and grabs the screen: inert
entries are crisp grey, an entry set inert and then live is back in the menu's colours,
and keyboard navigation onto an inert entry shows the subtle hover with grey text.
New: tests/test_repo_conventions.py::test_no_menu_entry_is_greyed_out_with_tk_disabled_state
(AST scan of the GUI package) and
tests/test_gui_release_fixes.py::test_an_entry_a_row_cannot_use_is_coloured_inert_not_disabled.
The three existing menu tests compare with the two new constants.
Five mutation registry entries (Sockets moved to the new line, Port check, the connection
table, the component going back to state=, a call site doing so), each run and caught.
Ran locally: the guard tests of the changed files, the convention guards, ruff and mypy.
The full suite runs here in CI on Linux and Windows.

Bug Fixes
- Inapplicable right-click menu options in the Connections, Sockets, and Port Check tables now appear greyed out instead of blurred. Available options retain their normal appearance.

On Windows, Tk draws a disabled menu label twice: first in the system's 3-D highlight colour, one pixel down and right, then in -disabledforeground. Nothing in Tk turns the first pass off, and on the dark menu the white copy made an entry the row cannot use look blurred and brighter than a live one. It showed in the Sockets and Port check row menus, and the connection table had the same code. theme.set_menu_entry_available keeps the entry in the normal state and colours it inert (DIS_FG text, a subtle hover), and hands every colour back to the menu when the entry applies again. All three row menus use it. Every command behind these entries already checks the row, so a click on an inert entry does nothing. Checked on real Tk 9.0 and 8.6 by posting the menu and grabbing the screen. New tests: an AST guard that no GUI code greys a menu entry out with state=, and a test of the component, plus five mutation entries. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

📝 Walkthrough

Walkthrough

Unavailable row-menu entries in the connection, Sockets, and Port check tables now use inert colors instead of Tk’s disabled state. The existing conditions that determine entry availability remain in place.

Changes

Context menu styling

Layer / File(s)	Summary
Shared menu styling `beantester/gui/theme.py`	Added live and inert menu option mappings and `set_menu_entry_available`. The helper applies the selected mapping without changing the entry’s state.
Row-menu integration and regression checks `beantester/gui/pages/conns.py`, `beantester/gui/toolbox/portcheck.py`, `beantester/gui/toolbox/sockets.py`, `tests/test_gui_release_fixes.py`, `tests/test_gui_state.py`, `tests/test_mutation_registry.py`, `tests/test_repo_conventions.py`, `tests/test_toolbox.py`, `CHANGELOG.md`	The three row menus use the shared helper with their existing availability conditions. Tests check the live and inert styling and flag menu calls that set a `state` keyword. The changelog records the appearance change.

- Line 661: Update the menu entry configuration using MENU_ENTRY_LIVE and
MENU_ENTRY_INERT so unavailable entries use a platform-specific disabled state
on Aqua/macOS, while retaining the color-only treatment on Windows. Adjust the
convention test to allow this controlled Aqua fallback.
- Line 653: Add parameter and return type annotations to the public
set_menu_entry_available helper, using types that match the supported menu
objects, index, availability flag, and its actual return behavior.
