From 9ad22109bb9d819ddcb19718cbe7a95c1764a8d9 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Pedro=20C=C3=B4rte-Real?= Date: Sun, 28 Jul 2019 11:29:48 +0100 Subject: Make sure we don't calculate fractional pixel gaps When gaps are resized for lack of space the calculation could result in a gap size of non-integer pixels. This would result in containers located at non-integer pixels which would be subtly broken. --- sway/tree/arrange.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/sway/tree/arrange.c b/sway/tree/arrange.c index e4f59110..bac9f2fa 100644 --- a/sway/tree/arrange.c +++ b/sway/tree/arrange.c @@ -71,7 +71,7 @@ static void apply_horiz_layout(list_t *children, struct wlr_box *parent) { double total_gap = fmin(inner_gap * (children->length - 1), fmax(0, parent->width - MIN_SANE_W * children->length)); double child_total_width = parent->width - total_gap; - inner_gap = total_gap / (children->length - 1); + inner_gap = floor(total_gap / (children->length - 1)); // Resize windows sway_log(SWAY_DEBUG, "Arranging %p horizontally", parent); @@ -150,7 +150,7 @@ static void apply_vert_layout(list_t *children, struct wlr_box *parent) { double total_gap = fmin(inner_gap * (children->length - 1), fmax(0, parent->height - MIN_SANE_H * children->length)); double child_total_height = parent->height - total_gap; - inner_gap = total_gap / (children->length - 1); + inner_gap = floor(total_gap / (children->length - 1)); // Resize windows sway_log(SWAY_DEBUG, "Arranging %p vertically", parent); -- cgit v1.2.3
