From 25f5cdd3a6e05f0e82d9e03ffd0889056d4ca8e1 Mon Sep 17 00:00:00 2001 From: tokyo4j Date: Sat, 21 Sep 2024 01:11:27 +0900 Subject: [PATCH] Refactor the logic of placing client-menu with ShowMenu action Before this commit, we assumed `ShowMenu` action is not bound to any buttons other than window menu button and always place the client-menu under the window-menu button when atCursor="no". Also, it was going to be difficult to distinguish whether the action is executed from the window menu button or the window icon, which will be added soon. This commit fixes it to open the menu under the actually-clicked button by passing `cursor_context` to `actions_run()`, with some refactoring: - `seat->pressed.resize_edges` is removed and it's calculated from the cursor position and `seat->pressed.type` just before running Resize action. This slightly changes the existing logic to determine the resizing edges with Alt-Right + Drag mousebinding, but `seat->pressed.type` is still stored on button press so it doesn't bring back the issue #543. - `seat->pressed.toplevel` is removed and `get_toplevel()` in `update_pressed_surface()` may be called more often, but its overhead will be negligible. --- include/action.h | 11 ++++++- include/labwc.h | 17 +++------- include/ssd.h | 1 + src/action.c | 74 ++++++++++++++------------------------------ src/input/cursor.c | 31 +++++++------------ src/input/keyboard.c | 4 +-- src/input/tablet.c | 2 +- src/input/touch.c | 2 +- src/menu/menu.c | 4 +-- src/seat.c | 24 +++++--------- src/ssd/ssd.c | 4 +++ src/window-rules.c | 2 +- 12 files changed, 67 insertions(+), 109 deletions(-) diff --git a/include/action.h b/include/action.h index 799c15ce..7130d701 100644 --- a/include/action.h +++ b/include/action.h @@ -7,6 +7,7 @@ struct view; struct server; +struct cursor_context; struct action { struct wl_list link; /* @@ -34,8 +35,16 @@ void action_arg_from_xml_node(struct action *action, const char *nodename, const bool actions_contain_toggle_keybinds(struct wl_list *action_list); +/** + * actions_run() - Run actions. + * @activator: Target view to apply actions (e.g. Maximize, Focus etc.). + * NULL is allowed, in which case the focused/hovered view is used. + * @ctx: Set for action invocations via mousebindings.
