From a223030b70c8e360f81b820244705e007e3ac1ec Mon Sep 17 00:00:00 2001 From: Brian Ashworth Date: Sun, 23 Dec 2018 10:54:54 -0500 Subject: Change mouse buttons to x11 map and libevdev names This modifies the way mouse bindings are parsed. Instead of adding to BTN_LEFT, which results in button numbers that may not be expected, buttons will be parsed in one of the following ways: 1. `button[1-9]` will now map to their x11 equivalents. This is already the case for bar bindings. This adds support for binding to axis events, which was not possible in the previous approach. 2. Anything that starts with `BTN_` will be parsed as an event code name using `libevdev_event_code_from_name`. This allows for any button to be mapped to instead of limiting usage to the ones near BTN_LEFT. This also adds a dependency on libevdev, but since libevdev is already a dependency of libinput, this should be fine. If needed, this option can have dependency guards added. Binding changes: - button1: BTN_LEFT -> BTN_LEFT - button2: BTN_RIGHT -> BTN_MIDDLE - button3: BTN_MIDDLE -> BTN_RIGHT - button4: BTN_SIDE -> SWAY_SCROLL_UP - button5: BTN_EXTRA -> SWAY_SCROLL_DOWN - button6: BTN_FORWARD -> SWAY_SCROLL_LEFT - button7: BTN_BACK -> SWAY_SCROLL_RIGHT - button8: BTN_TASK -> BTN_SIDE - button9: BTN_JOYSTICK -> BTN_EXTRA Since the axis events need to be mapped to an event code, this uses the following mappings to avoid any conflicts: - SWAY_SCROLL_UP: KEY_MAX + 1 - SWAY_SCROLL_DOWN: KEY_MAX + 2 - SWAY_SCROLL_LEFT: KEY_MAX + 3 - SWAY_SCROLL_RIGHT: KEY_MAX + 4 --- sway/input/cursor.c | 59 +++++++++++++++++++++++++++++++++++++++++++++++------ 1 file changed, 53 insertions(+), 6 deletions(-) (limited to 'sway/input/cursor.c') diff --git a/sway/input/cursor.c b/sway/input/cursor.c index ad9b9835..444fe81d 100644 --- a/sway/input/cursor.c +++ b/sway/input/cursor.c @@ -1,5 +1,6 @@ #define _POSIX_C_SOURCE 200809L #include +#include #ifdef __linux__ #include #elif __FreeBSD__ @@ -982,6 +983,18 @@ static void handle_cursor_button(struct wl_listener *listener, void *data) { transaction_commit_dirty(); } +static uint32_t wl_axis_to_button(struct wlr_event_pointer_axis *event) { + switch (event->orientation) { + case WLR_AXIS_ORIENTATION_VERTICAL: + return event->delta < 0 ?
