Use <MouseWheel> instead of the X11 <Button-4>/<Button-5> events, which Tk 8.7 dropped, in test_sidebar's test_mousewheel. In test_configdialog, assert the 'disabled' state flag alone instead of the exact ttk state tuple (which transient pointer states break), and restore the tests' method masks with addCleanup().

Several IDLE GUI tests fail on newer Tk or are fragile under display scaling. All test-only.
test_sidebartest_mousewheelfails on Tk 8.7+, which replaced the X11<Button-4>/<Button-5>wheel events with<MouseWheel>; the test now sends the button events only on Tk before 8.7. Verified on Tk 8.5.19, 8.6.17, 8.7b1, 9.0.3 and 9.1b1.test_configdialogcompared ttk widget states with exact tuples, which break when a widget picks up transientactive/hoverstates from the pointer (whose position shifts with the display scaling). The tested methods only toggledisabled, so the tests now assert that flag alone.Several
test_configdialogtests re-mask a method at the end, which is skipped on a mid-test failure (leaving the real method in place for the rest of the class);addCleanup()now makes the restore unconditional.🤖 Generated with Claude Code
