From bf5933c501a3c1705715b62dc1507df2bf0a4d2b Mon Sep 17 00:00:00 2001 From: Ryan Dwyer Date: Sat, 22 Sep 2018 10:42:59 +1000 Subject: Implement tab cycling using mouse wheel Firstly, a change had to be made to the container_at functions. If you create layout `T[view H[view view]]` and hover the second tab, the container_at functions would return the focus_inactive child. They now return the split container itself. To compensate for this, dispatch_cursor_button has been adjusted to find the focus_inactive child before focusing it. The actual implementation of wheel scrolling is pretty straightforward. This uses handle_cursor_axis, so I took a similar approach to handle_cursor_button (ie. creating a dispatch_cursor_axis function). --- sway/input/cursor.c | 49 +++++++++++++++++++++++++++++++++++++++++++++---- 1 file changed, 45 insertions(+), 4 deletions(-) (limited to 'sway/input/cursor.c') diff --git a/sway/input/cursor.c b/sway/input/cursor.c index 85951c09..5111e8e5 100644 --- a/sway/input/cursor.c +++ b/sway/input/cursor.c @@ -911,9 +911,10 @@ void dispatch_cursor_button(struct sway_cursor *cursor, return; } - // Handle clicking a container surface + // Handle clicking a container surface or decorations if (cont) { - seat_set_focus_container(seat, cont); + node = seat_get_focus_inactive(seat, &cont->node); + seat_set_focus(seat, node); seat_pointer_notify_button(seat, time_msec, button, state); return; } @@ -930,12 +931,52 @@ static void handle_cursor_button(struct wl_listener *listener, void *data) { transaction_commit_dirty(); } +static void dispatch_cursor_axis(struct sway_cursor *cursor, + struct wlr_event_pointer_axis *event) { + struct sway_seat *seat = cursor->seat; + + // Determine what's under the cursor + struct wlr_surface *surface = NULL; + double sx, sy; + struct sway_node *node = node_at_coords(seat, + cursor->cursor->x, cursor->cursor->y, &surface, &sx, &sy); + struct sway_container *cont = node && node->type == N_CONTAINER ? + node->sway_container : NULL; + enum wlr_edges edge = cont ? find_edge(cont, cursor) : WLR_EDGE_NONE; + bool on_border = edge != WLR_EDGE_NONE; + bool on_titlebar = cont && !on_border && !surface; + + // Scrolling on a tabbed or stacked title bar + if (on_titlebar) { + enum sway_container_layout layout = container_parent_layout(cont); + if (layout == L_TABBED || layout == L_STACKED) { + struct sway_node *active = + seat_get_active_tiling_child(seat, node_get_parent(node)); + list_t *siblings = container_get_siblings(cont); + int desired = list_find(siblings, active->sway_container) + + event->delta_discrete; + if (desired < 0) { + desired = 0; + } else if (desired >= siblings->length) { + desired = siblings->length - 1; + } + struct sway_container *new_focus = siblings->items[desired]; + node = seat_get_focus_inactive(seat, &new_focus->node); + seat_set_focus(seat, node); + return; + } + } + + wlr_seat_pointer_notify_axis(cursor->seat->wlr_seat, event->time_msec, + event->orientation, event->delta, event->delta_discrete, event->source); +} + static void handle_cursor_axis(struct wl_listener *listener, void *data) { struct sway_cursor *cursor = wl_container_of(listener, cursor, axis); wlr_idle_notify_activity(cursor->seat->input->server->idle, cursor->seat->wlr_seat); struct wlr_event_pointer_axis *event = data; - wlr_seat_pointer_notify_axis(cursor->seat->wlr_seat, event->time_msec, - event->orientation, event->delta, event->delta_discrete, event->source); + dispatch_cursor_axis(cursor, event); + transaction_commit_dirty(); } static void handle_touch_down(struct wl_listener *listener, void *data) { -- cgit v1.2.3-54-g00ecf
