From 1118cf1810f08b9bc0e7a767230ec08de0cb6adb Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Florian=20M=C3=BCllner?= Date: Fri, 17 Jan 2014 09:54:14 -0500 Subject: [PATCH] switcherPopup: Fix spacing calculation for empty lists Without special-casing, our current spacing calculation results in negative size requests for empty lists, which will trigger a Clutter assert later. While the list is never supposed to be empty, bugs happen; crashing users' systems is the least graceful way of handling this, so don't do it. https://bugzilla.gnome.org/show_bug.cgi?id=722434 --- js/ui/switcherPopup.js | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/js/ui/switcherPopup.js b/js/ui/switcherPopup.js index e6036b089..b06be6185 100644 --- a/js/ui/switcherPopup.js +++ b/js/ui/switcherPopup.js @@ -509,7 +509,7 @@ const SwitcherList = new Lang.Class({ _getPreferredWidth: function (actor, forHeight, alloc) { let [maxChildMin, maxChildNat] = this._maxChildWidth(forHeight); - let totalSpacing = this._list.spacing * (this._items.length - 1); + let totalSpacing = Math.max(this._list.spacing * (this._items.length - 1), 0); alloc.min_size = this._items.length * maxChildMin + totalSpacing; alloc.natural_size = alloc.min_size; this._minSize = alloc.min_size; @@ -539,7 +539,7 @@ const SwitcherList = new Lang.Class({ let childHeight = box.y2 - box.y1; let [maxChildMin, maxChildNat] = this._maxChildWidth(childHeight); - let totalSpacing = this._list.spacing * (this._items.length - 1); + let totalSpacing = Math.max(this._list.spacing * (this._items.length - 1), 0); let childWidth = Math.floor(Math.max(0, box.x2 - box.x1 - totalSpacing) / this._items.length);
