From c604ada385e046e9307571fa078972d2b1815987 Mon Sep 17 00:00:00 2001 From: Carlos Garnacho Date: Wed, 3 Oct 2018 22:43:21 +0200 Subject: [PATCH] clutter: Do not latch modifiers on modifier keys If the user maps eg. Alt+F2 to a pad button, the MetaInputSettings will send the full Alt press, F2 press, F2 release, Alt release sequence. However the keycode corresponding to Alt is found in level 1, so the Shift modifier gets unintendedly latched in addition to the Alt key press/release pair. We could probably improve keycode lookup heuristics so level=0 (and no modifier latching) is preferred, but we can do without it altogether for modifier keys. --- clutter/clutter/x11/clutter-virtual-input-device-x11.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/clutter/clutter/x11/clutter-virtual-input-device-x11.c b/clutter/clutter/x11/clutter-virtual-input-device-x11.c index b86ded0d0..e16ba3fd0 100644 --- a/clutter/clutter/x11/clutter-virtual-input-device-x11.c +++ b/clutter/clutter/x11/clutter-virtual-input-device-x11.c @@ -147,14 +147,16 @@ clutter_virtual_input_device_x11_notify_keyval (ClutterVirtualInputDevice *virtu return; } - if (key_state == CLUTTER_KEY_STATE_PRESSED) + if (!_clutter_keymap_x11_get_is_modifier (keymap, keycode) && + key_state == CLUTTER_KEY_STATE_PRESSED) clutter_keymap_x11_latch_modifiers (keymap, level, TRUE); XTestFakeKeyEvent (clutter_x11_get_default_display (), (KeyCode) keycode, key_state == CLUTTER_KEY_STATE_PRESSED, 0); - if (key_state == CLUTTER_KEY_STATE_RELEASED) + if (!_clutter_keymap_x11_get_is_modifier (keymap, keycode) && + key_state == CLUTTER_KEY_STATE_RELEASED) clutter_keymap_x11_latch_modifiers (keymap, level, FALSE); } -- 2.20.1
